Overview of BSS integration
1 Overview of BSS integrationBSS integration instructions are intended to be used during the integration of the TCSM-BSC-BTS system in the final location.
The BSS integration testing can be started when the commissioning of the different network elements has been done.
The purpose of the BSS integration tests is to ensure that the BSC, TCSM, and BTS operate correctly together in the GSM/GPRS/EDGE network. When the BSS integration tests have been performed, the base station subsystem can be taken into use.
There are different product variants of the Base Station Controller: BSCi, BSC2i, BSC3i660, BSC3i 1000, BSC3i 2000, Flexi BSC and mcBSC. Flexi BSC has two vari-ants: upgraded Flexi BSC and new delivery Flexi BSC.
In the Flexi BSC, new HW elements CP1D-A ( New processor unit with multicore capa-bility), ETP(Exchange Terminal for Packet Transmission for Packet Abis over TDM and Packet Abis over Ethernet) and ETP-A (Packet gateway for AoIP) are introduced to support 4200 TRX, Packet Abis over ETH or TDM and Packet gateway for AoIP.
There are ETIP1-A plug in unit and ESB24-D plug-in unit. The ETIP1-A plug in unit provides one active and one protecting Gigabit Ethernet interface. The ETIP1-A is rep-resented by two functional units: Exchange terminal for IP transmission unit ETIP and Ethernet Exchange Terminal unit (EET). The EET represents a functional unit of a physical GigE Ethernet interface.
The ESB24-D plug-in unit is used with Ethernet based Message Bus (EMB) as a collec-tor of EMB LANs from the CPU units in both new delivery and upgraded Flexi BSC. ESB24-D can also be used as a generic LAN switch in the new delivery Flexi BSC.
The mcBSC (Multicontroller BSC) can be used in two ways. It can be used as a totally new BSC option for new installations with standalone multicontroller BSC modules.
Thesecond one is - capacity can be flexibly extended for the existing installed Flexi BSC base using the new HW module implementation of the Multicontroller. In this case, mcBSC enables the evolution of installed Flexi BSCs towards multicontroller capability.
Transcoding functionality is usually performed in a separate standalone network element (TCSM2/TCSM3i/mcTC), and the interface between the Base Station Control ler (BSC) and the transcoder (TC) is called Ater. As an alternative to standalone 2G transcoders MGW offers the Ater interface (2G transcoder) functionality. Thus transcod ing can be performed also by the transcoder located in the Multimedia Gateway (MGW).In creation of the Ater connection to the Multimedia Gateway, no configuration or controlling the TCSM is needed. The TCSM and the transcoder in the MGW are con figured differently in the BSC. For information, see Multimedia Gateway Product Docu mentation. The mcTC is used as a transcoding solution for standalone and combined mcBSC cases. TCSM2 and TCSM3i can be used in parallel with mcTC in combined mcBSC. Combined BSC/TCSM installation is also supported here.
As a part of capacity upgrade for TCSM3i, IC209-A cabinet is used to allow the equip-ping of five full shelf wide transcoder cartridge. Cabling Cabinet is not equipped with E1 balanced interfaces if new Rear Cabling Modules are used. TC1C-A is the new cartridge for TCSM3i and ETP-A is the new Exchange Terminal for Packet Transport. The capacity in one S15 standalone TCSM3i cabinet is 14400 channels.The capacity of one S15 combined TCSM3i cabinet in full configuration is 16800 channels, but 16320 channels is the maximum capacity reached, due to the channel sales configuration step.

BSS Integration Overview of BSS integration
Id:0900d8058086ac4fConfidential
Creating a connection to the network management system for BSC2i and BSC3i is described in the following documents:
• Integrating 2GBSS to NetAct in NetAct documentation
Creating a connection to the SGSN is described in SGSN Integration in SGSN docu-mentation. Creating the connection in BSC is described in Enabling GPRS in BSC in BSC documentation.
Creating a connection to the Cell Broadcast Centre is described in BSC-CBC Integration in BSC documentation.
Creating TCP/IP connections through LAN switches for BSC3i is described in BSC Site IP Connectivity Guidelines in BSC documentation.
For more information on the effects due to mcBSC, please check BSS21341: A over IP and BSS21454: Packet Abis over Ethernet in BSC documentation.
Any detected fault should be reported with a Nokia problem report and the report should be sent to the Customer Service Centre.
BSS integration procedureThe main phases of the testing are executed in the order presented here. BSS integra-tion consists of the following phases:
1. Creating the A interface2. Synchronising the A interface3. Adding DN2, SSS, DMR and BBM to the service channel4. Creating the Abis interface5. Creating X.25 or LAN connections. See Integrating 2GBSS to NetAct in NetAct doc-
umentation (for BSC2i and BSC3i).6. Initialising base stations7. Testing BSS integration
Test logs can be filled in during the testing.

A interface protocol layers
2 A interface protocol layersIn the ETSI environment, the A interface is defined in accordance with CCITT#7 Signal-ling System. In the ANSI environment, the A interface is defined in accordance with ANSI SS7 Signalling System. Three protocol layers are used: the Message Transfer Part (MTP), the Signalling Connection Control Part (SCCP), and the BSS Application Part (BSSAP; with ETSI) or the Radio System Application Part (RSAP; with ANSI), as shown in the figure below.
Figure 1 Three layers of CCS7/SS7 signalling between MSC and BSC
The MTP's task is to provide a reliable means of data transmission. It consists of a sig-nalling link, a signalling link set, and a signalling route set.
The SCCP complements the services of the MTP by providing connectionless and con-nection-oriented network services. It consists of SCCP subsystems.
The BSSAP/RSAP uses the services of the MTP and the SCCP. It takes care of actual GSM/DCS-related interaction between the MSC and the BSS. Typical tasks of the BSSAP/RSAP are for example call control, location updates, handover management, and paging. It has no counterparts in terms of BSC MMI but is created along with the SCCP.

3 A interface configuration with TCSM2 and TCSM3iThe A interface configuration can be made in many different ways depending on the equipment, or capacity and redundancy requirements. For example, the transcoder can be either TCSM2 or TCSM3i. Likewise, it is possible to implement only one PCM, E1 (used in ETSI environment), or T1 (used in ANSI environment) line between the MSC and the BSC or to use several separate PCM lines for redundancy or capacity purposes. The following figure illustrates an A interface configuration example.
With both TCSM2 and TCSM3i, the A interface is always multiplexed.
Figure 2 A interface configuration example
Signalling can also be performed using IETF signalling transmission (SIGTRAN). For more information, see SIGTRAN Configuration for the A Interface.
Multipoint A Interface enables one BSC to be connected to several core network elements (MSCs or MSC Servers). Even though one core network element fails, the network can stay operational with reduced capacity. For more information, see Multi-point A Interface in BSC.
TCSM3i for combined BSC/TCSM installationIn combined BSC/TCSM installation, no E1 or T1 interfaces are used as Ater interfaces between the BSC and TCSM3i. Instead, internal serial broadband interfaces (SBI) or Hotlinks are used. STM-1/OC-3 or IP/Ethernet (GigE) interfaces are used as external A interfaces.

A interface configuration with TCSM2 and TCSM3i
In TCSM3i for combined BSC/TCSM installation with a Flexi BSC, a mixed ETS2 and ETIP1-A configuration (STMU and SET, and ETIP and EET units) is possible in A-inter-faces.
TCSM3i
The TCSM3i uses an allocation with 16 kbit/s traffic channels for the use of HR speech, FR speech, EFR speech, AMR (FR and HR) speech traffic, and FR data traffic. An example is shown in the table below.

The basic requirement for high-speed circuit-switched data (HSCSD) data transmission capability is that the associated BSC is equipped with an 8 kbit/s switching network or Bit Group Switch. Channel allocations for TCSM3i configured to transmit the data exclu-sively at the maximum rate of 32 kbit/s (type H) and 64 kbit/s (type I) are shown in the following tables. The same allocations accept also speech channels (FR/EFR, HR) instead of data, allowing an optimised use of transmission capacity for mixed speech/data use. The capacity unit reserved for an HSCSD connection on the A-inter-face is:
• 8–32 kbit/s (4 bits of a timeslot) for a 2 × 16 kbit/s channel • 8–64 kbit/s (an entire timeslot) for a 4 × 16 kbit/s channel

TCSM2, ETSIProvided that the BSC is equipped with an 8 Kbit group switch (GSWB), four separate A interface lines can be put into one highway PCM, making it possible to have up to 120 full-rate speech channels in one highway PCM cable. In half-rate configuration the maximum number of speech channels is 210. The combination of half-rate and full-rate can also be used.
The maximum efficiency is achieved if the recommendation for time slot allocation is followed (shown in the figure Time slot allocation for full-rate traffic on Ater 2 Mbit/s inter-face with the TCSM2 (ETSI)).
Signalling channels, and possibly network management system connections, are always allocated beginning from the end of the frame. This optimises the number of the traffic channels available for the fourth tributary. This is due to the fact that only the time slots preceding the first signalling time slot can be used as speech channels in the fourth tributary.
For example, if signalling links are allocated to time slots 31 and 27, only the time slots 25 and 26 are available for the fourth tributary - even if time slots 30, 29, and 28 are not used at all.

TCSM2, ANSIBecause of multiplexing, four A interface T1s can be put to one highway T1, making it possible to have up to 96 traffic channels between the transcoder and the BSC as shown in figure A interface time slot allocation (ANSI). However, one channel is required for the LAPD channel and normally one 64 kbit time slot is used for SS7 signalling. This leaves 91 channels for traffic.

ET indexes in BSC
4 ET indexes in BSCIn new delivery Flexi BSC both STM-1/OC-3 interfaces (optical) and IP/Ethernet (GigE) interfaces (optical or electrical) are supported in the whole cabinet wide cartridge mechanics together with E1/T1 interfaces. Cartridge mechanics is divided to sub car-tridges, which are used same way as smaller cartridges in earlier delivered BSCs. In upgraded Flexi BSC one-cabinet configuration is supported with full range (16+16) of STM-1/OC-3 interfaces and IP/Ethernet (8 + 8 GigE) interfaces. In the upgraded Flexi BSC it is possible to extend the configuration with a second cabinet also to full support for 800 E1/T1 interfaces to earlier delivered BSCs.
The Exchange Terminals (ETs) of the BSC3i 1000/2000 and the upgraded Flexi BSC are housed in GT6C-A and/or GT4C-A cartridges. One GT4C-A cartridge can contain up to eight ET plug-in units and a GT6C-A cartridge can contain up to four ET plug-in units. ET16 plug-in units can be installed to six ET cartridges with indexes ETC 0 to ETC 5 in BSC3i 2000. Additionally, ET16 units can also be equipped to GTIC cartridges to achieve a maximum of 800 E1/T1 interfaces amount in the two-cabinet configuration and 384 E1/T1 interface amount in the one-cabinet configuration.
The ET16 and ETIP1-A units are installed to GTIC cartridge starting from the right in mixed ET16 or ETIP1-A and ETS2 equipping. In the incoming direction, the ET decodes the 2048 Mbit/s in European Telecommunications Standards Institute (ETSI) signal or 1544 Mbit/s American National Standards Institute (ANSI) signal of a circuit into data signals.
In the outgoing direction, the ET receives a binary PCM signal from the switching network and generates the PCM frame structure. The resulting signal is converted into a line code (HDB3 in the ETSI environment, B8ZS or AMI in the ANSI environment) and transmitted further onto the 2048 Mbit/s (ETSI) or 1544 Mbit/s (ANSI) circuit.
The ETS2 plug-in unit contains up to two active and two redundant optical STM-1/OC-3 interfaces. All optical components have 2N redundancy for transmission protection. A maximum of 16 active optical interface can be achieved with 8 plug-in units, if two active interface per unit is used or with 16 plug-in units if one active interface is used per unit.
The ETS2 units are equipped to GTIC cartridges in the first equipment cabinet. The GTIC cartridges can also be used for E1/T1 connectivity with ET16 units. The ETS2 unit is responsible for framing, mapping, and multiplexing of PCMs into channelised way in optical interfaces (VC12). One STM-1 interface consists of 63 E1s (ETSI) and one OC-3 interface consists of 84 T1s (ANSI). PCMs are handled in the same way as ETs in the ET16 plug-in unit.
Equipment protection for ETS2 (MSP 1 + 1 protective units) is provided if two STMU units (functional units for ETS2) are configured with consecutive indexes. For example, STMU-0 and STMU-1 comprise a pair of STMUs.
Integrated E1/T1 over IP application software offers an integrated solution for BSC3i and TCSM3i based transcoders to send/receive TDM frame timeslots via a packet-switched network. Integrated E1/T1 over IP is based on the circuit emulation service over packet-switched networks (CESoPSN) technology and it is implemented in the ETIP1-A plug-in unit. The ETIP1-A can be equipped to the ETS2 and ET16 cartridges to replace the E1/T1 or STM-1/OC-3 unit. This improves the BSC connectivity. The operator has more alternatives to select transmission technology in different interfaces of the BSC environment. The ETIP-A plug-in unit can be used in the Abis and Ater inter-faces in the BSC3i and in the A and Ater interfaces in TCSM3i based transcoders. The

TCSM3i for combined BSC/TCSM installationThe TCSM3i for combined BSC/TCSM installation refers to a way to configure TCSM3i by equipping TCSM3i with a BSC3i or Flexi BSC. The combined BSC/TCSM consists of one BSC3i 1000/2000/upgraded or new delivery Flexi BSC cabinet (also called master BSC) and one TCSM3i cabinet.
Note that when two or more TCSM3i cabinets are used the master BSC needs to be BSC3i 1000 or Flexi BSC.

ET indexes in BSC
The A interface is implemented by using the STM-1/OC-3 (SDH/SONET) or IP/Ethernet (GigE) interfaces instead of the ET16 (E1/T1) interface. Furthermore, the ET16 units in BSC's and TCSM3i's Ater interface are not used in this configuration.
Two duplicated hotlink cables are used between the BSC and the TCSM3i cabinet. In this application each hotlink cable carries 48 2Mbit/s PCM lines. The capacity of one STM-1 interface is 63 E1 PCMs and one OC-3 interface 84 T1 PCMs. BSC software treats STM-1/OC-3 interfaces as normal E1/T1 PCM lines.
The TCSM3i for combined BSC/TCSM installation with upgraded Flexi BSC brings some modifications to the structure of the BSC3i and TCSM3i: In BSC3i, the TCSA 0 cabinet replaces BCSU 6, the TCSA 1 cabinet replaces BCSU 5, and the TCSA 2 cabinet replaces BCSU 4 in the Group Switch GSW2KB. In TCSM3i, control PCM cables for STMUs/ETIPs both in the TCSA 0 and in the TCSA 1 cabinet are moved to other locations in the GSW2KB. Control PCM cables and control PCM allocations for STMUs/ETIPs in the TCSA 2 cabinet remain the same.
In the TCSM3i for combined BSC/TCSM installation, the ETIP1-A plug-in unit is con-nected to the BSC GSW by a hotlink and it is controlled by a separate LAPD link.
The capacity of one ETIP1-A plug-in unit in the TCSM3i for combined BSC/TCSM instal-lation environment is 126 E1 PCMs or 168 T1 PCMs.

BSC3i 660BSC3i 660 can have up to two ET4C-B cartridges in basic configuration.
With the 256 PCM Bit Group Switch (GSWB), the two ET4C-B cartridges have space for 62 * (2*2) Mbit ET PCM's plug-in units in ETSI or 62 * (2*1.5) Mbit ET PCM's plug-in units in ANSI (32 pcs in ET4C 0, 30 pcs in ET4C 1). This makes it possible to have a maximum of 124 ET PCMs in one BSC3i 660. See figure ET4C-B cartridges with GSWB and ET2A/ET2A-T(B)/ET2E-S/SC/ET2E-T(B)/ET2E-TC(B) indexes in BSC3i 660.
With the 1024 PCM Bit Group Switch (GSW1KB), the two ET4C-B cartridges have space for 64 * (4*2) Mbit ET PCM's plug-in units in ETSI or 64 * (4*1.5) Mbit ET PCM's plug-in units in ANSI (32 pcs in ET4C 0 and 32 pcs in ET4C 1). This makes it possible to have a maximum of 256 ET PCMs in one BSC3i 660. See figure ET4C-B cartridges with GSW1KB and ET4A/ET4E/ET4E-C indexes in BSC3i 660.
With the GSW1KB Bit Group Switch it is also possible to mix ET2 and ET4 plug-in units in the BSC3i 660, so that each BSC3i 660 equipped with GSW1KB can have both ET2 and ET4 plug-in units with the restriction that one ET4C-B shelf must be equipped with either ET2 plug-in units or ET4 plug-in units. See figure ET4C-B cartridges with GSW1KB and ET2A/ET2A-T(B)/ET2E-S/SC/ET2E-T(B)/ET2E-TC(B) indexes in BSC3i 660.

BSS Integration Creating the A interface
Id:0900d805807d47d0Confidential
5 Creating the A interfaceIn this phase the MSC, the transcoder, and the BSC are configured to enable the MSC and the BSC to communicate properly with each other.
For more information on connecting a BSC to other core network elements, see Multi-point A Interface in BSC.
For an overview, see Overview of BSS integration.
5.1 Connecting the A interface ETEach A interface needs its own ET. The ETs used for the A interface must be the ones that supply synchronisation to the BSC's CLS units. There are three such ETs per BSC, and their default unit numbers are shown in the table below. It is possible to use any other ET for the synchronisation by changing the position of the corresponding synchro-nisation cable in the ET cartridge.
*RoHS compliant ET2A-TB, ET2E-TB and ET2E-TCB units are created to the equip-ment database as ET2A-T , ET2E-T and ET2E-TC.
Steps
1 Check that the ET is connected (WUP).ZWUP:<PCM numbers>;
If the ET is already connected, it has a controlling BCSU (Base Station Controller Sig-nalling Unit) and process info. The controlling process can be SC7PRB A interface, ABIPRB Abis interface, SI1PRB ISDN Abis interface, or ERATES Gb interface.

2 To implement this step, choose one of the following alternatives:
a If ET is already connected
Then
Check that the ET is in WO state and restart the ET (USU).The state of the ET can be changed with command USC.
The ET must be restarted to ensure that the correct ET software is loaded into the unit.
ZUSU:ET,<pcm_index>,C=TOT;
Note that all ET's in the same plug-in unit will be restarted concurrently.
b If ET is not connected
Then
Connect the ET (WUC).ZWUC:ET,<unit index>:<plug-in unit type>,0:IF=A:BCSU,<bcsu index>;

Note that you have to select the line interface (T1 or E1) in ET16 with a micro switch. For more information see ET16 C109519 in Jumper Settings of the Plug-in Units in BSC3i and in TCSM3i.
If the controlling BCSU is not already in WO-EX state, the state of the BCSU must be changed to WO-EX. Once the BCSU's state is WO-EX, the state of the ET can be changed to WO-EX, too.
t When using ET2E/A, ET2E-C, ET2E-S/SC, ET2E-T(B), ET2A-T(B), or ET2E-TC(B) plug-in units, connect the even-numbered ET before the odd-numbered.
When using ET4A, ET4E, ET4E-C, or ET16 plug-in units, first connect the first logical ET of the cartridge.
3 Check and change the functional modes for the ET if needed.The status of the frame alignment mode must be the same at both ends of the PCM line.
For ET1E cards the frame alignment mode is set by strapping.
For ET2E/A, ET2E-C, ET2E-S/SC, ET2E-T(B), ET2A-T(B), ET2E-TC(B), ET4A, ET4E, ET4E-C, or ET16 the frame alignment mode is set by MML. The frame alignment mode strapping in them is used only during the unit restart when the software cannot be loaded for some reason.

increases the connectivity of the network element. One STM-1 (ETSI) interface can carry 63 E1 PCMs and one OC-3 (ANSI) interface 84 T1 PCMs.
STM-1/OC-3 interfaces are implemented with ETS2 plug-in units, each of which can handle two interfaces.
For more information, see Configuring the STM-1/OC-3 interface in STM-1/OC-3 (SDH/SONET) Interface.
Steps

5.3 Connecting the PWE interfacePurposeThis section describes how to connect the A interface when IP/Ethernet (GigE) trans-mission is used. The IP/Ethernet interfaces are implemented with ETIP plug-in units.
For more information, see Creating the unit connections in ETIP/PWT User Guide.
When there is no existing IP/Ethernet based Ater interface connection between BSC and TCSM3i, the user needs to configure BSC and TCSM3i locally. When you do this for the first time use one of the Ater interface master TR3E/TR3A/TR3T plug-in units, otherwise remote connections are not possible later.
Steps
1 Create the cartridge, functional unit, ET groups and plug-in units for the ET groups.For detailed instructions and commands, see Creating and managing ETIPs in Creating and Managing BSC Hardware.

5.4 Creating the transcoder devicesIn this phase the transcoder is configured. The transcoder is needed between the MSC and the BSC for speech compression. It compresses 64 kbit speech time slots coming from the MSC to 16 or 8 kbit speech time slots going to the BSC. Decompression is carried out in the opposite direction.

Creating the A interface
Choose one of the following procedures, depending on the type of TCSM and the type of configuration used.
5.4.1 Creating the TCSM3i
PurposeWhen the standalone TCSM3i is created into the BSC hardware database, its functional unit is TCSM and both transcoder types are controlled by the BSC via the LAPD link. The TCSM3i software is also kept in the BSC hard disks from where it can be down-loaded to the TCSM3i whenever necessary.
One transcoder based on TCSM3i hardware consists of one TR3E (ETSI), TR3A (ANSI), or TR3T (ETSI or ANSI) plug-in unit and either one ET16 or one ETIP plug-in unit (as Ater interface). ETP-A unit for the Packet Transport is included in the stand alone TCSM3i, also mixed with ET16 and ETIP plug-in units (as A interface).
In TCSM3i, both ET16 and ETIP plug-in units are equipped only with supervised TR3E/TR3A/TR3T units.
When IP/Ethernet (GigE) connections are used as Ater interfaces, Ater PCM cablings are delivered in a general optional set for ETIP used as Ater interface. The ETIP1-A plug-in unit on the Ater interface is always HW protected, so an optional set for HW pro-tection is always used in Ater interfaces for standalone TCSM3i with IP/Ethernet (GigE) interfaces
One TCSM3i can handle a maximum of four TC-PCMs on the A interface when 16 Kbit/s submultiplexing is used on Ater interface. 8 Kbit/s Ater submultiplexing is not supported by the TCSM3i.
One TCSM3i cabinet can contain up to 96 transcoder units in 6 cartridges as shown in the figure below. The same principles apply in both ET16 and ETIP configurations.

For more information on TCSM3i cabinet configurations, please refer TCSM3i cabinet configuration and capacity.
As shown in the following table, a certain number of TR3E/TR3A/TR3T units act as masters who supervise the ET16 plug-in units. When the master TR3E/TR3A/TR3T plug-in units are taken into use, the ET16 plug-in units are also equipped.

Creating the A interface
* acts as a cartridge master when two BSCs are connected to one cartridge
To ensure that the TCSM3i capacity is fully exploited, its transcoding functions can be shared between several BSCs. This is achieved by connecting two BSCs to one TCSM3i cartridge. In this kind of configuration one BSC uses the first eight TR3E/TR3A/TR3T plug-in units and the other BSC the last eight TR3E/TR3A/TR3T plug-in units. Additional ET16 plug-in units must be installed to the TCSM3i for the second BSC Ater interface to the TCSM3i cartridge.
For more information on configuring ETIP plug-in unit and creating the IP/Ethernet (GigE) configuration, see ETIP/PWT User Guide.

10 Change the state of the TCSM3i to WO-EX (USC).This command automatically changes the state of the TCSM LAPD link to WO-EX. If the TCSM3i software does not exist or is different from that in the BSC, it is downloaded in this phase.
11 Check the state of the TCSM3i LAPD link (DTF).ZDTF:TCSM,<unit index>:OMU;
The transcoder has less PCM types than the BSC has pools. This results in the fact that when you are checking the PCM circuits from the transcoder end, the PCM types are different than the pools in the BSC.

5.4.2 Creating TCSM3i for combined BSC/TCSM installationThe growing capacity of the BSC results in the increased transmission capacity between the BSC and the MSC. For example, the BSC3i 2000 has a capacity of 12000 erlangs. This means the user has to configure 99/124 PCM cables between the BSC and the transcoders, translating to 396/496 A-interface PCM cables. To avoid using such a huge number of PCM cables, synchronous transmission on optical media (cable) is intro-duced.
In the ETSI environment, synchronous transmission is standardised by Synchronous Digital Hierarchy (SDH). Interface to optical media is called STM-N, where N defines the transmission speed.
In ANSI environment synchronous transmission is standardised by SONET and inter-face is called OC-x, where x defines the transmission speed. One STM-1 interface can handle 63 E1 PCM's capacity and one OC-3 interface can handle 84 T1 PCM's capacity.

TCSM3i for combined BSC/TCSM implements same transcoding functionality and features as standalone version. It is possible to distribute TCSM3i's capacity between several BSCs. The BSC3i which is combined or installed together with the TCSM3i is called the Master BSC. A Remote BSC is located away from the TCSM3i and its Ater PCMs are connected to TCSM3i cabinet via Master BSC's E1/T1 PCM lines, optical STM-1/OC-3, or IP/Ethernet (GigE) connections.
1. Creating TCSM unit to Master BSCThe Master BSC must always be a BSC3i 1000, BSC3i 2000 or Flexi BSC.
2. Sharing TCSM3i for combined BSC/TCSM transcoding capacity to remote BSCA Remote BSC can be BSC3i 1000, BSC3i 2000, Flexi BSC, or even older models. If the remote BSC does not support IP/Ethernet (GigE) or optical interfaces, ET inter-faces can be used.If the BSC in a combined BSC/TCSM installation is BSC3i 1000, it is possible to install up to three TCSM3i cabinets. With Flexi BSC there can only be one TCSM3i cabinet.
The procedure below contains the ETSI command examples for creating the transcoder into the Master BSC. You can find more detailed information in the document BSC3i upgrade for combined BSC/TCSM in the release binder.

5.4.3 Creating the TCSM2The TCSM2 is a functional unit of the BSC. The BSC monitors the TCSM2 by using a LAPD link which is connected from the TCSM2's Transcoder Controller (TRCO) to the BSC's Operation and Maintenance Unit (OMU). The LAPD link is allocated to the 2 Mbit/s PCM frame (ETSI) or 1.5 Mbit/s T1 frame (ANSI) that carries the TCH/CCS7 between the MSC and the BSC. It is a 16 kbit/s link using the first two bits in time slot one (for ETSI, see figure Time slot allocation for full-rate traffic on Ater 2Mbit/s interface with the TCSM2 (ETSI) and for ANSI, figure A interface time slot allocation (ANSI)). In addition to monitoring, the LAPD link is also used for configuring, alarms, remote MMI sessions, and for software downloading to the TCSM2.
The TCSM2 software is kept in the BSC's hard disks and consists of three modules; software for the TRCO units, for the ET2E/A, ET2E-C, ET2E-S/SC, ET2E-T(B), ET2A-T(B), or ET2E-TC(B) units, and for the TR16 (ETSI) or TR12 (ANSI) units. These software modules are downloaded to the TCSM2 when necessary, that is when there is no software in the TCSM2 or it is different from that in the BSC.

One TCSM2 rack can contain up to eight transcoder units as shown in figures TCSM2 rack and cartridges (ETSI) and TCSM2 rack and cartridges (ANSI). Each transcoder unit consists of the transcoder cartridge and one ET cartridge having up to four ET2E/A, ET2E-C, ET2E-S/SC, ET2E-T(B), ET2A-T(B), or ET2E-TC(B) plug-in units.

Figure 17 TCSM2 rack and cartridges (ANSI)
The TCSM2 rack, transcoder and ET cartridges along with the plug-in units are created to the BSC's equipment database. It is important to create the configuration and espe-cially the transcoder ETs correctly to the BSC since they are used to define the type and the number of the A interface PCMs (in ETSI) or T1s (in ANSI). This information is used by the transcoder when it configures its PCMs/T1s during restart.
The procedure consists of the following phases:
• Configuring the hardware for the TCSM2 (steps 1–8) • Connecting the TCSM2 functional units (steps 9–14) • Configuring the TCSM2 (steps 15–16)
In this procedure, parameter unit index refers to the number of the ET in the BSC.

Creating the A interface
The table below shows which A-interface pools support which codecs and application software.
12 Connect the TRCO to the BSC (WUC).This command creates the LAPD link between the BSC and the TCSM2. A circuit group DTCSM and the circuit to it are created at the same time.
ZWUC:TCSM,<unit index>:TRCO,0;
13 Change the state of the TCSM2 to WO-EX (USC).This command automatically changes the state of the TCSM LAPD link to WO-EX. If the TCSM2 software does not exist or is different from that in the BSC, it is downloaded in this phase.
14 Check the state of the TCSM2 LAPD link (DTF).ZDTF:TCSM,<unit index>:OMU;
The transcoder has less PCM types than the BSC has pools. This results in the fact that when you are checking the PCM circuits from the transcoder end, the PCM types are different than the pools in the BSC. The following execution printouts illustrate this:

Limitations in Multimedia Gateway (MGW) line card IW1S1 capacityWhen using TDM over STM-1 (IW1S1/IW1S1-A units) for user plane traffic, the capacity may be limited. The total IW1S1 capacity in U3B & U3C is 1602 timeslots.
For more information on this limitation, see the section IW1S1 and IW1S1-A with MX622 capacity limitation for user plane traffic in Routing and Digit Analysis in MGW in the Mul-timedia Gateway Product Documentation.

Degradation of TCSM3i capacity can be totally avoided if SDH multiplexer is used between TCSM3i and MGW.
The maximum capacity of TCSM3i in combined installation can not be fully used due to the limitation of MGW line card. A maximum of 7896 channels of the TCSM3i capacity can be used in ETSI environment. An alternative to overcome the ill effects of this limi-tation is to leave four TR3E plug-in units in every TC2C cartridge unequipped in the TCSM3i for combined BSC/TCSM. This results in the MGW supporting the TCSM3i with a maximum of 7680 channels in an ETSI installation.
5.5 Creating Ater Connection to Multimedia GatewayMultimedia Gateway (MGW) implements the same base transcoding functionality and features as TCSM. However, MGW does not support the same pool set as the BSC. Fur-thermore, MGW and TCSM3i do not support 8kbit/s submultiplexing on Ater interface, but TCSM2 does.
There is no O&M LAPD link between BSC and MGW so BSC does not control MGW at all. This means that the user is responsible for creating identical transcoder configura-tions to both BSC and MGW. Since there is no LAPD link, there is no need to equip TCSM functional unit into the BSC HW database.

5.8 Creating the speech channelsSpeech circuits are used to carry the actual user data through the A interface. One circuit is needed for each ongoing call. With conventional hunting the circuit is chosen by the MSC which means the MSC has to know the circuits of the BSC and their status. That is why the circuits must be identified by both the MSC and the BSC. This is accom-plished by using CICcodes. A CIC code consists of the CCSPCM and the time slot of the circuit. The CIC codes must be the same at both ends.
Reversed Hunting can be activated here. The following instructions apply when activat-ing it in a new BSC. If you want to change the BSC to use Reversed Hunting instead of normal hunting, see Activating and Testing BSS10005: Reversed Hunting.
For more information on Reversed Hunting, see Circuit configuration on the A interface in Half Rate, and A interface circuit allocation in Radio Channel Allocation.
Note that Multipoint A Interface cannot be used if Reversed Hunting is activated.

Synchronising the A interface
6 Synchronising the A interfaceFor an overview, see Overview of BSS integration.
Before you startThe A and Ater interface transport has been connected into operation between the core Network and the BSC. In the BSC the user has to select the ETs that will be used as synchronisation inputs and install the synchronisation cables between the selected ETs and the clock unit.
Normally three ETs are used for synchronisation. The synchronisation input with the highest priority (2M1) should be in the state CONNECTED and in use (USED INPUT). The other inputs (2M2 and 2M3) should be in the state CONNECTED.
Steps
1 Check the state of the synchronisation (DRI).ZDRI;
Expected outcomeNormally, it gives the following output:
CL1TG:
INPUT STATE USED INPUT PRIORITY----- --------------- ---------- ----------2M1 CONNECTED 2M1 72M2 CONNECTED - 62M3 CONNECTED - 5SYNCHRONISATION UNIT WORKING MODE .........

2 Create or delete synchronisation inputs if necessary (DRC, DRD).ZDRC:<synchronization input>;
ZDRD:<synchronization input>;
The number of possible synchronisation inputs depends on how many transport lines are connected between the core network and the BSC. The maximum number of A/Ater lines that can be used as synchronisation lines is 3 if CL1TG is used.

3 Change the supervision timers for the inputs if necessary (DRS).Use the DRS command.
4 Check if there are any faults.The following steps include typical faults and instructions on how to correct them.
Steps
a To implement this step, choose one of the following alternatives:
1 If The synchronisation units are not in synchronous operation mode.
Then
Force the synchronisation units to use a specific input (DRS).ZDRS::U=<2M1 - 2M4>;
2 If The CL1TG will search the entire control range in order to lock the units to a certain input.
Then
Wait for the alarm to be cancelled (which may take a couple of minutes) and remove the forced use of input (DRS).ZDRS::U=OFF;
3 If Operation mode is not hierarchical.
Then
Check that the operation mode has been set to hierarchical (DRM).ZDRM:H;
4 If The settings of the ETs are not correct.
Then
Check the settings of the ETs.The TCL signal should be 8 kHz. In ET1E it is selected by strapping, but in other ET variants it is 8kHz permanently.
5 If The control words of both CL1TGs approach the values 0 to 65534.
Then
Check the connection.It is possible that the incoming circuit is connected to a loop.
5 Change the synchronisation inputs.
Steps
a Disconnect the incoming signal from the first input.
Expected outcomeThis will cause normal circuit alarms. After a time delay of more than the timer: SYN-CHRONISATION SIGNAL MALFUNCTION TOLERANCE TIME allows, both syn-

chronisation units will change to the second input. This can be seen in the LEDs of the CL1TG plug-in units and on the alarm printer:
2641 FAILURE IN SYNCHRONISATION SIGNAL
0630 SYNCHRONISATION SIGNAL CHANGED
b Disconnect the incoming signal from the second output.
Expected outcomeThe results should be similar to the earlier ones.
6 Go to plesiochronous mode of operation.Disconnect the incoming signal from the third input (the last synchronisation input has been disconnected) in CL1TG.
Expected outcomeThe synchronisation units will go to PLESIOCHRONOUS OPERATION mode. All syn-chronisation input indicators in the active CL1TG unit will extinguish, only the current indicator light is on. All 3/4 input indicators in the passive CL1TG unit are lit, but not the current indicator light. The alarm printer will print out the following:
2641 FAILURE IN SYNCHRONISATION SIGNAL
2631 OPERATION MODE CHANGED TO PLESIOCHRONOUS
7 Return to synchronous mode of operation.Return the circuits to their normal state one by one starting from the circuit with the lowest priority.
Expected outcomeThe synchronisation units will synchronise themselves to the input 2M3/2M4 after a time delay of more than the timer REPAIRED SYNCHRONISATION INPUT OBSERVATION TIME. On the alarm printer the following alarms will be cancelled:
2641 FAILURE IN SYNCHRONISATION SIGNAL
2631 OPERATION MODE CHANGED TO PLESIOCHRONOUS
8 Check possible slips in the synchronous mode of operation (YMO).ZYMO:ET,<index>:SLI;
The observation begins daily at 00.00 and should normally show no slips.
9 Check oscillator adjustments.The CL1TG has no adjustments in the synchronous mode of operation.

Id:0900d805805cedebConfidential
7 Adding DN2, SSS, DMR and BBM to the service channelThe connection between the BSC and the managed equipment is established either through a BSC-BTS O & M link or a Q1 service channel. The possible equipment types at a Base Transceiver Station (BTS) site include Base Station Interface Equipment (BIE), Transmission Unit (TRU), Digital Microwave Radio Link (DMR), and other trans-mission equipment (TRE).
All equipment with the same alarm unit type must have a unique index in the BSC con-cerned. All equipment in the same channel must have a unique address.
DN2 The Q1 service channel comes in TSL31 bits 7-8 to the 2M port of the DN2 interface unit (IU2). The Q1 service channel is forwarded through an extra loop connection to the Control Unit (CU); either one port of the IU2 is connected to the 2M interface of the CU or two IU2 ports are con-nected together with a local cable. The supported baud rates of the service channel are 1200, 2400 and 4800.
SSS The Supervisory Substation is located in the same rack with other trans-mission equipment, normally with the DN2. The Q1 service channel is forwarded to the SSS with a local cable.
DMR The Digital Microwave Radio link cannot pick the Q1 service channel from a time slot. The Q1 service channel is forwarded to the DMR with a local cable from another source, normally DN2. The supported baud rates of the service channel are 1200, 2400, 4800, and 9600.
BBM The Baseband Modem cannot pick the Q1 service channel from a time slot. The Q1 service channel is forwarded to the BBM through an Inte-grated Line Terminal (ILT) plug-in unit from the DN2.
TRE Other types of transmission equipment, for example optical line equip-ment, are handled in the BSC with the common name Transmission Equipment (TRE).

BSS Integration Initialising base stations
Id:0900d805807d4158Confidential
9 Initialising base stationsEach base station has one LAPD link called OMUSIG (see figure Abis interface). It is connected to the Operation and Maintenance Unit (OMU) of the base station and used for O&M purposes like remote sessions to the BTS, software up- and downloading, transferring of alarms, and transferring of configuration information.
Each TRX has one LAPD link called TRXSIG and up to eight traffic channels. There can be fewer traffic channels if some of the TRXs' radio interface time slots are used for sig-nalling. The bit rate of the LAPD links can be either 16 or 64 kbit/s. Also 32 kbit/s is possible for TRX links.
In this phase, the LAPD links are created and the base stations are created to the BSC's radio network database. In terms of BSC, a base station consists of BCF, BTSs, TRXs, and handover and power control parameters.
The hardware database is attached only to Talk-family base stations. In the other types, the TEI of the TRX links is the same as the TRX number in the BSC. The TEI of the OMU links is always 1.
In the case of Flexi EDGE base stations, the TRXSIG links and traffic channels data created in the BSC can be downloaded and used by the Flexi EDGE base station auto-matically. For more information, see Flexi EDGE BTS Commissioning in the Flexi EDGE Base Station Product Documentation.
The following instructions apply to Talk-family, UltraSite EDGE, MetroSite, Flexi EDGE, Flexi Multiradio and BTSplus base stations.
For an overview, see Overview of BSS integration.
9.1 Creating LAPD links and a base station, and initialising the base station parametersA LAPD link can be created either to a certain physical Base Station Controller Signal-ling Unit (BCSU) or to a logical BCSU address. When the link is created to a logical BCSU address the actual controlling unit may not necessarily be the one given in the command. The concept of logical BCSU address was introduced to eliminate the effect of BCSU switchovers to radio network planning. In terms of MMI commands, only the command name is different with logical BCSU addresses.
It depends on the type of the BTS which links must be created. For more information, see Creating D channels on Abis interface.
Steps
1 Create LAPD links (DSE).Create 16, 32 or 64 kbit LAPD links. Create the links for O&M signalling link (OMUSIG) and TRX signalling links (TRXSIG). If you are creating a 64kbit link, do not give <SUB-TSL>.

Initialising base stations
If logical BCSUs are used, use the DSL command with the same parameters.
2 Create a base control function (EFC).The base control function (BCF) is a logical counterpart of the actual base station. It is connected to the OMUSIG link created earlier.
As a default, the operational state of the new BCF is 'Locked' (L). It is recommended that you first create the entire BCF site (BCF, BTS, and the TRXs) and unlock the TRXs and BTSs of the BCF, before you change the state of the BCF to 'Unlocked'.
In the case of Flexi EDGE Base Station, the administrative state of BCF is also 'Locked' after creation, but it is created as 'Automatic Unlock Allowed' by default. It means that when the BTS site has been commissioned and it indicates the start up for the BSC, the BSC automatically changes the administrative state of the BCF to 'Unlocked'.
• All site types if it is being autoconfigured:ZEFC:<bcf identification>,<site type>:DNAME=<D-channel link set name>;
Further informationThe BCF parameters can be modified later with the EFM and EFT commands if needed.
3 Create a base transceiver station (EQC).A base transceiver station (BTS) is a logical counterpart of a sector in a base station site. It should not be confused with a base station even though they have the same abbrevi-ation.

Further informationYou can modify the power control parameters with the EUG, EUA, EUQ, and EUS com-mands.
6 Create default handover control parameters (EHC).Each cell must have a handover parameter set.
ZEHC:BTS=<BTS identification>;
You can modify the handover control parameters with the EHG, EHA, EHS, EHQ, EHI, EHD, EHN, EHX, EHY, EHP commands.
7 Create neighbouring cell information (EAC).Define the list of cells where mobiles can make a handover when using the cell.
Create the adjacent cells.
• Adjacent cell located in the same BSC:ZEAC:BTS=<BTS identification>:ABTS=<adjacent cell identification>;
• Adjacent cell located in a different BSC:ZEAC:BTS=<BTS identification>:LAC=<location area code>,CI=<cell identification>:NCC=<network colour code>,BCC=<BTS colour code>,FREQ=<BCCH frequency>,:
The adjacent cell parameters can be modified with the EAM command.
8 Check and change the synchronisation of TalkFamily, UltraSite, Flexi EDGE, and MetroSite BTSs if necessary (EFM).Check that the synchronisation is suitable. The default is the internal clock of the BTS.
Change the synchronisation of the BCF to external synchronisation if necessary.
If the synchronisation settings are not defined or synchronisation is not enabled for the BCF(s) in the BSC Radio Network database, then the BTS site's own synchronisation settings are valid.
There are three alternative ways to define synchronisation for the BTS (and LMU) via BSC: the internal clock of the BTS, BSS synchronisation, and Site synchronisation.
For further information on changing synchronisation settings of base stations, see BSS Synchronisation.

t This is done only for Talk-family base stations.
The BTS hardware database contains the base station's hardware configuration. Hardware database files are kept in the BSC's hard disks in BCF_PACK\HWDATA directory as shown in figure BTS software directories.
Before you startBefore proceeding, you must have suitable hardware database files available. For infor-mation on how to prepare a BTS hardware database, see BTS documentation.
Steps
1 To implement this step, choose one of the following alternatives:
a If The BTS does not yet have a valid hardware database
Then
Once the BTS hardware configuration is available, copy it to the BSC.The database files are:
HWDATA_T.<ext> Database file in text format
HWDATAOM.<ext> Database file in binary format
b If The BTS already has a valid hardware database
Then
Upload the hardware database to the BSC (EVU).If the BTS already has a valid hardware database, it can be uploaded to the BSC instead of copying new files with the command EVU.
2 Create BCF hardware database (EVC).Once the hardware database files have either been copied or uploaded to the BSC, the database must be created.
ZEVC:<database id>:NAME=<file name>,EXT=<file extension>;
3 Attach hardware database to the BCF (EVA).ZEVA:<bcf identity>:<database id>;
4 To implement this step, choose one of the following alternatives:

Then
Activate the hardware database without downloading (EVV).ZEVV:<bcf identity>:PAS:NODL;
b If The hardware database is not in the flash

9.4 Taking the base station into useIn this phase, the base station is taken into use by unlocking it.
Steps
1 Change status of BTS D-channels (DTC).Change the state of the Operation and Maintenance (OMU) link and the TRX links to WO-EX:
ZDTC:<D-channel link set name>:,WO;
2 Unlock the TRXs (ERS).If the higher level objects are already unlocked the transition from locked to unlocked causes a TRX reset in the BTS site. Otherwise, the reset is not done.
ZERS:BTS=<BTS identification>,TRX=<transceiver identification>:U;
3 Unlock the BTSs under the BCF (EQS).If the BCF is already unlocked the transition from locked to unlocked causes a BTS reset in the BTS site. Otherwise, the BTSs are not reset.
ZEQS:BTS=<BTS identification>:U;
4 Unlock the BCF (EFS).ZEFS:<BCF identification>:U;
Expected outcomeThe transition from locked to unlocked causes a BCF reset. While the BCF is resetting, all its components and the BCF itself are in BL-RST (blocked-reset) state. During that time, the BCF is not available for traffic nor controllable by MML.

10 Testing BSS integrationBefore you startThe test requires one of each network element (BTS, BSC, MSC, and HLR), and in fault conditions a PCM/T1 analyser (PC with GSM Protocol Analyser to trace A/Abis mes-sages). All the network elements and connections must be operative and the network configuration valid.
Figure 23 The test arrangements
The test cases are described in a general level. For more detailed information, refer to BSC SW release material: BSC System Test Cases and BSC Release Test Cases.
For an overview, see Overview of BSS integration.
