Notes:

•Multiservice aggregation layer - the capacity to use Ethernet as a common transmission layer to transport any kind of traffic, independently by the type of interface. Ethernet becomes the convergence layer.

• Service awareness - traffic handling and quality management, queuing traffic according to the type of service assigned, independently by the type of interface

• Packet node - no service aggregation limits with all traffic aggregated in packets, in term of: capacity, type of service requirements and type of interface

• Service-driven adaptive modulation- fully exploit the air bandwidth in its entirety by changing modulation scheme according to the propagation availability and allocate transport capacity, discriminating traffic by different services, only possible in a packet-based environment



Notes:

• 9500 MPR aggregates and carries over a COMMON PACKET LAYER: TDM 2G, 3G, LTE and IP/Ethernet. This allows sharing of common packet transmission infrastructures, regardless of the nature of carried traffic.

• Due to the nature of Ethernet, each service can be discriminated based on several parameters like quality of service.

• Mapping different access technologies over Ethernet is achieved by standardized protocols like circuit emulation and pseudo-wire.

• R99 - original standard for UMTS WCDMA based networks

• HSDPA (High Speed Data Packet Access) - add on to R99/UMTS networks which adds a shared high speed downlink packet channel

• ISAM (Indexed Sequential Access Method) - a method for indexing data for fast retrieval

• UMTS (Universal Mobile Telecommunications System – 3rd generation mobile cellular technology for GSM-based networks.

• WCDMA (Wideband Code Division Multiple Access) – interface standard found in 3G mobile telecommunications networks.

• WiMAX (Worldwide Interoperability for Microwave Access) - telecommunications protocol that provides fixed and mobile Internet access



Notes:

• Service awareness means the ability to discriminate the different traffic types carried over the converged Ethernet stream. Our traffic flow can be composed of E1, E3, STM-1, ATM, DS1, DS3, and/or IP/Eth, coming from different sources, and therefore having different requirements. For instance, DS1 or ATM traffic from a 3G base station can carry voice (high priority, real time service) and data (lower priority and possibly non real time with high variability load, such as internet browsing, music download or video streaming).

• Service awareness is what allows identifying the traffic types, and in the case of non real time variable bit rate one, optimize the band with overbooking of the radio scarce resource.



Notes:

• 9500 MPR offers a SINGLE PACKET MATRIX able to switch, aggregate and handle any of the possible incoming traffic types with virtually no capacity limits (up to 10 GB/s).

Note: The TDM can be also E3.

• The MSS can also provide Gigabit Ethernet (GigE) and metallic uplinks.

• Packets can be transported over Ethernet or PDH in any direction, avoiding service aggregation bottlenecks in terms of capacity, service types and interface types.



Notes:

• Traffic with high priority will always have bandwidth available, like voice (deterministic approach)

• Broadband traffic is discriminated by QoS dynamically, with modulation scheme changes driven by propagation conditions.



Notes:

This true packet product is not based on TDM (circuit-based) technology, so it efficiently transports multimedia traffic by handling packets natively while still supporting legacy TDM. It also adapts packets to the air conditions and quality required by different service types. This product improves packet aggregation, increases bandwidth, and optimizes Ethernet connectivity.

n Low cost, ½ rack length, Very low power consumption, MW radio protection, Hybrid & Packet operational modes

• Multipurpose ODU è the MPT; to cover all MW applications under a single platform

n Zero foot print for Ethernet applications, common to all MSS platform, enables integrated solution for MPLS metro network

• Introducing 9500 MPR-e è stand-alone “full outdoor”

• Existing compatibility with 9500 MXC



Notes:

• CAC (Call Admission Control) - prevents oversubscription of VoIP networks. It is used in the call set-up phase and applies to real-time media traffic as opposed to data traffic.

• CBR – Constant Bit Rate

• DWRR (Deficit Weighted Round Robin) - is a scheduling method for packets of variable size. A maximum packet size number is subtracted from the packet length, and packets that exceed that number are held back until the next visit of the scheduler.

• HPQ (High Preempt Queue)



Notes:

• IMA (Inverse Multiplexing over ATM) - a standardized technology used to transport ATM traffic over a bundle of T1 or E1 cables where a stream of Asynchronous Transfer Mode cells is spread over multiple physical links.

• Backward compatibility with hybrid installed base



Notes:

• 9500 MPR in the stand alone (zero-footprint) architecture is built by only one unit for Ethernet applications:

• Outdoor Unit.

• Outdoor Unit is connected to the MPLS metro networks equipment with one coaxial cable for the power supply and one Ethernet optical or electrical cable (with MPT).

• 9500 MPR in the split mount architecture is built by two separate units:

• MSS (Microwave Service Switch): indoor unit for split mount and stand alone configurations (Ethernet uplink)

• Outdoor Unit.

• MSS and Outdoor Unit are connected with a single standard coaxial cable (with ODU300) or with one coaxial cable for the power supply and one Ethernet optical or electrical cable (with MPT).

• Up to 6 ODU300 can be connected to an MSS-8

• Up to 2 ODU300 can be connected to an MSS-4

• Up to 18 MPT can be connected to an MSS-8. Up to 8 can be powered directly by the MSS-8 shelf.

• Up to 14 MPT can be connected to an MSS-4



Notes:

• Link Aggregation groups a set of ports so that two network nodes can be interconnected using multiple links to increase link capacity and availability between them.

•When aggregated, two or more physical links operate as a single logical link with a traffic capacity that is the sum of the individual link capacities.

• This doubling, tripling or quadrupling of capacity is relevant where more capacity is required than can be provided on one physical link.

• Link aggregation also provides redundancy between the aggregated links. If a link fails, its traffic is redirected onto the remaining link, or links.

• If the remaining link or links do not have the capacity needed to avoid a traffic bottleneck, appropriate QoS settings are used to prioritize traffic so that all high priority traffic continues to get through.

• The Link Aggregation is performed according to 802.3ad and can be applied to Radio ports and to User Ethernet ports.



Notes:

• The 9500 MPR Node supports up to 18 RF links for operation on the same or different frequency bands using the MSS-8.

• The ODU for each link is connected to a plug-in card inside the site aggregator.

• Other plug-in cards provide line interface access (TDM and native IP), management, and so on.

• 9500 MPR Node supports a mix of non-protected and protected or diversity operation for single link, repeater or star radio configurations.

It sends/receives standard Ethernet packets to/from both Core-E modules, manages the radio frame (on Ethernet packet form) generation/termination, the interface to/from the alternate Radio module (for RPS management), the cable interface functions to ODU; it contains the logic for the EPS Core-E protection, the RPS logic.

• MPT access card (with PFoE): this unit is used to interface the MPT. PFoE (Power Feed over Ethernet) is used to carry the power supply to the MPT-HC through an electrical Ethernet traffic connector.

• The optional +24 Vdc/-48 Vdc Converter unit (to be installed in transport slot 4, 6 or 8 of MSS-8 can be used to power the MSS for +24 Vdc office applications.



Notes:

To manage more directions the “Stacking configuration” can be realized by installing up to 3 MSS, interconnected through the Ethernet ports in the Core-E module. In the example of Figure are shown two interconnected MSS.



Notes:

• With the Core protection max. 3 MSS can be interconnected as shown in figure.

• To implement this configuration the LOS alarm on the Ethernet ports must be enabled as switching criterion of the Core protection. To enable this alarm the “Ethernet LOS Criteria” feature has to be enabled.

• The Ethernet optical cable is preassembled and available in different lengths (up to 350 m).

• A special cord adapter must be connected to the coaxial cable on the MPT-HC V2.

• MPT-HC V2 must be connected to a fuse or a breaker on a customer power distribution box. The recommended value is 3 Amps.




Notes:

Two MPT-HC V2 are installed and connected to the power injector, and interconnected through the XPIC and RPS cables.



Notes:

• If MPT-HC V2 final installation will be in optical on the pole mounting don't insert SFP module, use a simple Ethernet cable connected to the RJ45 port for provisioning phase.

• Verify on the PC, that the MCT application has been installed.

• Configure the PC network card interface.

• Launch the MCT by double clicking on file MctStarter.jar, located under the path created by the operator during the local copy and under \\WebEML MPR TCO 4.4\9500MCT_V02.0X.XX\MctStarter.jar


Notes:

MPT-HC must be connected to a fuse or a breaker on a customer power distribution box. The recommended value is 3 Amps.



Notes:

• TDM to TDM – This is the typical service associated to a traditional TDM network in which E1/T1 traffic is transported, switched and terminated inside a MPR network.

• TDM to ETH – This is the service allowing the TDM traffic to be aggregated and output in a single ETH stream. On this service specific algorithms are applied in order the E1/T1 is transported, switched and provided to an external ETH network in standard format (MEF-8).

• SDH to SDH – This is the typical service associated to a traditional SDH transport network. STM-1 traffic is transparently transported, switched and terminated inside a MPR network.

• ETH to ETH (ETSI) DATA (ANSI) – This is not a real CES due to the native IP architecture of MPR. Ethernet traffic is directly managed by the L2 switch on the Core board, thanks to the auto-learning algorithm, VLANs etc.

• ATM to ATM (ETSI) – This profile allows the management of the ATM services inside a 9500 MPR network. E1s IMA/ATM are terminated/reconstructed at the borders of the 9500 MPR cloud; encapsulation/extraction of ATM streams into/from ATM PW packets is performed according to RFC 4717.

• ATM to ETH (ETSI) – This profile allows the ATM service to be terminated and encapsulated into an Ethernet stream towards an IP/MPLS Core Network.



Notes:

• Definition: This service identifies a flow inside MPR network, in which E1/T1 is transported, switched and terminated.

• Application: Typical microwave 2G backhauling application, in which E1/T1s are terminated before entering into aggregation network.



Notes:

• Definition: E1/T1 TDM input signals are packetized according to MEF8 standard; E1/T1s are transported, switched and provided to an external ETH network in standard format (MEF-8).

• Application: Typical microwave 2G backhauling application, in which E1/T1s are terminated before entering into aggregation network, where aggregation network is a packet network. E1/T1s are not terminated at the end of the microwave backhauling and an end-to-end circuit emulation services could be established between 9500 MPR and the service router in front of BSC/RNC



Notes:

• Definition: This service identifies a flow inside MPR network, in which STM-1 is transparently transported, switched and terminated.

• Application: Typical microwave transport application.



Notes:

• Definition: Ethernet traffic is transported and switched automatically by the standard auto-learning algorithm of the built-in MPR 10 Gbit Ethernet switch.

• Application: Typical microwave 3G backhauling/WiMax application, in which transport of Ethernet packets coming from base stations is requested.



Notes:

• TDM2TDM and TDM2ETH profiles are managed in compliancy with Metro Ethernet Forum specifications

• MEF 8- Implementation Agreement for the Emulation of PDH Circuits over Metro Ethernet Networks

• Same behavior than PDH/SDH transmission devices (QoS)

• Reduced impact of the “packetization” overhead

• Same Radio performances than PDH/SDH devices



Notes:

Case 1 for E1/T1 (TDM2TDM over MPR network)

• The E1/T1 stream is inserted in Node 1 and extracted in Node 2. In this case the two IWFs used to packetize the traffic for the Ethernet switch in the Core-E module are both internal to the 9500 MPR network. The Circuit Emulation Service is TDM2TDM in Node 1 and Node 2. The Cross connections are PDH-Radio type.

Case 1 for STM-1 (SDH2SDH)

• The STM-1 stream is inserted in Node 1 and extracted in Node 2. In this case the two IWFs used to packetize the traffic for the Ethernet switch in the Core-E module are both internal to the 9500 MPR network. The Circuit Emulation Service is SDH2SDH in Node 1 and Node 2. The Cross connections are SDH-Radio type.

Case 2 (TDM2Eth)

• The E1/T1 stream is inserted in Node 1 and extracted in Node 2. One IWF is inside the 9500 MPR, the second IWF is external to the 9500 MPR-E network. The Circuit Emulation Service is TDM2ETH in Node 1 and Node 2. The Cross connections are PDH-Radio type in Node 1 and Radio-Eth type in Node 2.

Case 3 (TDM2Eth)

• The E1/T1 stream is inserted/extracted in Node 1. One IWF is inside the 9500 MPR, but the second IWF is external to the 9500 MPR network. The Circuit Emulation Service is TDM2ETH in Node 1 and Node 2. The Cross connections to be implemented are PDH-Eth type in Node 1.



Notes:

Cases 4 and 5 (ETH2ETH)

• In these cases Ethernet packets enter Node 1 and are extracted in Node 2. In case 4 the Ethernet packets encapsulate the E1 stream; in case 5 the packets are native Ethernet packets. None of the IWFs belongs to the 9500 MPR network. The Circuit Emulation Service is ETH2ETH in Node 1 and Node 2. No Cross connections must be implemented. The path is automatically implemented with the standard auto-learning algorithm of the 9500 MPR Ethernet switch.



Notes:

Case 6 for E1/T1 (TDM2TDM over Ethernet)

• The E1/T1 stream is inserted in Node 1 and extracted in Node 2. In this case the two IWFs used to packetize the traffic for the Ethernet switch in the Core-E module are both internal to the 9500 MPR network. The Circuit Emulation Service is TDM2TDM in Node 1 and Node 2. The Cross connections are PDH-Eth type.



Notes:

• Flow Id present (user defined)

• intermediate node configuration (E1/T1 provisioning):

• node by node (building Cross-connection tables based on Flow Id)

• bandwidth guaranteed (according to QoS à Highest Queue Priority association)

• no flooding-autolearning necessary



Notes:

• ECID = Emulated Circuit Identifier

• IWF = Inter-Working Function



Notes:


• all the parameters must be configured compliant with the MEF8 standard

• adaptive or differential clock recovery supported

• bandwidth guaranteed (according to QoS à Highest Queue Priority association)

• destination MAC added before going into whole network (MEF8 compliant)



Notes:

• ECID = Emulated Circuit Identifier



Notes:


• If there are intermediate nodes in each node build the Cross-connection tables based on Flow Id.

• Bandwidth guaranteed (according to QoS à Highest Queue Priority association)

• No flooding-autolearning necessary

• Both the IWFs belong to 9500 MPR-E and the packets are not supposed to exit the 9500 MPR-E network.



• In figure is shown a more detailed block diagram of the ASAP unit in Ingress.



Notes:

• Any packet belonging to an Eth2Eth TDM flow is treated as any other Ethernet packet with the only exception of giving it an higher priority based on the MEF 8 Ethertype.



Notes:

• The table summarizes the actions taken for specific reserved multicast addresses. Frames identified with these destination addresses are handled uniquely since they are designed for Layer 2 Control Protocols.

• The actions taken by the system can be:

• Discard - The system discards all ingress Ethernet frames and must not generate any egress Ether-net Frame carrying the reserved multicast address.

• Forward - The system accepts all ingress Ethernet frames as standard multicast frames and for-wards them accordingly.

• Peer - The system acts as a peer of the connected device in the operation of the relevant Layer 2 Control Protocol.



Notes:

• 9500MPR uses a Connection Admission Control (CAC) for committed services and two schedulers in series (on Core embedded L2 switch and on Radio peripheral)

• The two schedulers need to jointly interoperate to guarantee determistic behavior of the services

• The QoS function inside 9500 MPR-E is the result of a distributed implementation in the switch in the Core-E unit and Radio Interface unit. Both those QoS functions are properly configured in order to get the wished behavior on Ethernet flows that will be transmitted towards the Radio.

• The QoS configuration is the same for all the involved units:

• Core-E

• EAS

• Modem unit (to interface the ODU300)

• MPT-HC/MPT-HC V2/MPT-XP/MPT-MC



Notes:

• In the figure is shown an overview of the QoS implementation inside the Core-E unit and Modem unit which is used to interface the ODU300.

• The QoS feature provides eight internal queues to support different traffic priorities. The QoS function can assign the packet to one of the eight egress transmit queues.

• Queue 8 is assigned to TDM2TDM traffic (fixed assignment)

• Queue 7 is assigned to TDM2Eth traffic (fixed assignment)

• Queue 6 is assigned to TMN (fixed assignment)

• Queues 1 to 5 are assigned to Ethernet traffic according to the information inside the packet as 802.1p field or DiffServ field.



Notes:

• In case the configuration of radio interfaces changes from 1+0 to 1+1, the Radio QoS of Spare interface takes the queue sizes of the Radio QoS of Main interface. The previous configuration of queue sizes of the Radio QoS of Spare interface is lost.

• In case of the configuration of radio interfaces changes from 1+1 to 1+0, the Radio QoS of Main interface maintains the previous configuration of queue sizes, while the Spare interface takes the default queue sizes according to the configured Modem Profile.

• When a radio port is added to the L1 LAG port, all custom QoS and queue size configuration is lost.

• When a radio port is removed from a L1 LAG port, the NE QoS settings are applied to the radio port. The queue sizes are set to the default values.



Notes:

• In order to give an estimation of the maximum delay, that an Ethernet frame can experience when entering the specific queue in case of congestion of radio interface, the WebEML shows a read-only value, which is the queue size configured by the operator converted in a time value (msec).



Notes:

The weights can be changed, from the WebEML user interface.



Notes:

It is recommended to forward the jumbo frame only in the queue Q1 (lower priority).



Notes:

• In this example, user traffic is split up into radio channels. Main advantages:

• Throughput. The overall radio Ethernet throughput is more than 1 Gbit/sec (4 x 350 Mbit/s, being this the value for 256QAM@56 MHz)

• Protection. In case of a failure of one of the three channels, all the traffic is redirected on the remaining link (with a throughput of around 0.35 Gbit/sec). The discarded or dropped traffic is the one with lower priority: high priority traffic is still running on the remaining active channels.



Notes:

• In Layer1 Link Aggregation, the Distributor performs a packet-based traffic distribution over multiple links regardless of the content of the packets.

• The Distributor takes into account the number of bytes sent over a specific link and loads links according to the available bandwidth. As a consequence, Layer1 Link Aggregation allows a traffic load balancing independently of traffic content. Since the distribution does not depend on Layer2 or Layer3 header content, this kind of Link Aggregation is called Layer1 (i.e., associated to the physical layer).



Notes:

The following radio configurations are supported:

• 1+0 MPT-HC connected to P8ETH SFP port

• 1+0 MPT-HL connected to P8ETH SFP port

• 1+1 MPT-HL connected to P8ETH SFP port



Notes:

Radio L2 LAG ports configured in Active/Standby mode are NOT recommended in this release of the 9500 MPR.



Notes:

One MPT per MPT plug-in.



Notes:

The Ethernet ports involved in a LAG cannot be used as TMN In-band interface.



Notes:

After a user Ethernet port has been added to an Ethernet L2 LAG port, the following user Ethernet port parameters may not be modified:

• Link Capacity (10, 100, 1000 Mbps)

• Duplex Mode

• VLAN 802.1Q port priority

• VLAN 802.1Q port filter mode

• Auto Negotiation Enabled/Disabled

• Disable the port

• Synchronous Ethernet Operation Mode

• SynchE Master/Slave (electrical only)

• SSM support



Notes:

With MSS-1c and with MPR-e the SSM are transparency forwarded in most of the configurations.



Notes:

• On the radio channel, a 9500 MPR transfers the reference clock to an adjacent MPR device through the radio carrier frequency at physical layer.

• This method offers two main advantages:

• No bandwith is consumed for the synchronization distribution,

• Total immunity to the network load.

• End-to-end scenarios where time-of-day/phase alignment are requested are fully supported, as 1588 PTP v2 is carried transparently by MPR across the microwave backhauling network.

• Both for Hybrid and Packet working modes, the Clock can be received at hand-off or delivered at the cell site. Synch-Eth, E1, PDH and BITS clock modes are available.



Notes:

• The availability of the Clock in the Network represents the most common scenario, characterized by a time source available at the ingress of the microwave backhauling network, derived from the primary reference clock.

• Synchronization (frequency) is delivered to the cell site using any of the options available on MPR, depending on the operator’s need. Worth repeating ingress and egress methods can be mixed (i.e. Synch-Eth at the ingress, E1/T1 at the egress) via a simple configuration.



Notes:

• 9500 MPR has an embedded reference clock which is distributed to each board of the network element.

• Such clock is generated in the Clock Reference Unit (CRU) of the core unit (controller).



Notes:

• Differential: used in case of clock distribution on the whole network. It’s more reliable than Adaptive; also used in TDM2TDM traffic (MPR to MPR).

• Adaptive: simpler network, but performances depends on the PDV (Packet Delay Variation) in the Network. Always used when the reference clock isn’t distributed on the whole network.

• Node Timing: this feature (called either “network clock re-timing” or “node timing” or, according to G. 8261 wording, “network-synchronous operation for service clock”) introduces an additional possibility to recover E1 clock.

• Node timing is a way to recover TDM clock quite popular in the industry of service routers and site aggregator boxes. This feature inside the 9500 MPR platform is adding interworking capabilities with third parties service routers and circuit emulations gateway.

• In node-timing working mode, all the E1s are re-sampled with the network element clock. This means that, as also reported in G8261, this method does not preserve the service timing (E1 clock).

• Recovered E1 clock is according to G. 823 synchronization masks.



Notes:

• In meshed networks (rings) do not close the synchronization configuration.

• If the NODE TIMING is enabled, the CT still propose the possible selection between ACR and DCR: in this specific case, the meaning of this option is not related to the clock recovery algorithms but rather to the MRF8 frame format.



Notes:

• Differential clock recovery

• Common reference clock IS available at both Ends.

• IWF system, at RX side, generate output clock based on RTP TimeStamps which are sent together with each Fragments.

• Adaptative clock recovery

• Common reference clock is NOT available at both Ends.

• IWF system, at RX side, generate output clock based on data arrival rate: TDM clock is slowly adjusted to maintain the average fill level of a jitter buffer at its midpoint.



Notes:

• Each Module will mute its own Synchronization clock in case of Fail Alarm.

• For each available sync source, the CRU detects the signal Degrade Alarm on each available sync source. Such Signal Degrade alarm raises also in case of muted (missing) clock.

• The Signal Degrade Alarm relevant to the selected Synchronization Source, or the relevant Card Fail, causes the switching of the Synchronization Source.

• Each E1/T1 (board #, port #) must be associated to a signal flow ID



Notes:

Refer to the attached diagram as an example of the IP address assignment.



Notes:

• With the introduction of TMN In-Band two new IP interfaces are added to those already available.

• NE Local IP Address

• TMN Local Ethernet interface, IP/subnet

• TMN Out-of-Band interface on User Ethernet port 4, IP/subnet

• TMN In-Band interface #1, IP/subnet

• TMN In-Band interface #2, IP/subnet

• User Ethernet port 4 can then used as:

• pure Ethernet traffic interface

• pure Out-of-band TMN Local Ethernet interface

• Ethernet traffic interface carrying TMN In-Band traffic

• The NE Local IP Address can be reused on one of the other TMN interfaces. These interfaces must have different IP subnets.

Notes:

General Rules:

• One CSM-E/Core-E card is required (unprotected)

• Can be protected with 2nd CSM-E/Core-E

• One Flash card is required for every CSM-E/Core-E card



Notes:

• Gigabit Ethernet serial internal interfaces between CSM-E/Core-E and peripherals

• CSM-E/Core-E Macro Functions:

• Controller

• Layer 2+ Ethernet Switch, VLAN management and MAC based

• Ethernet MAC learning

• Cross-connect function for PDH and Data payload traffic;

• For any “packetized” flow, the switch will be in charge to also manage the Equipment Protection Switching (EPS).

• Quality of Service (QoS) management.

• Selection of the synchronization clock to be distributed to each plug-in.

• The flash card stores the license, equipment software, equipment MIB, and equipment MAC address.



Notes:

The SFP must be installed after the Configuration File has been downloaded. If the SFP has been installed before, withdraw it and then installed it again.



Notes:

For the correct operation of the EoSDH SFP it is necessary to disable the autonegotiation via WebEML or via the Configuration File.



Notes:

• Based on packet technology with 7 GbEth serial internal interfaces between Core-E and peripherals (jumbo frames 9728 bytes allowed)

• The Ethernet ports of the Core-E can be configured in two ways:

• to be used as GigaEthernet interface for Ethernet traffic (Note: for port#5 and port#6 the optional SFP must be installed);

• to be used to connect an MPT: MPT-HC (ETSI), MPT-HCV2, or MPT-MC (ETSI) to port#1 to port#4; an MPT-HC only to port#5 and port#6.

• The Core-E unit has the option to equip two SFPs (in port #5, port #6). These ports can be also used to connect directly an MPT-HC/MPT-HCV2.



Notes:

• The CSM-E/Core-E consists of microprocessor and Ethernet switch circuits. The Ethernet Switch provides a Quality of Service (QOS) mechanism to control all streams.

• If QoS is disabled, all traffic inside the switch has the same priority. This means that for each switch port there is only one queue, first in, first out (FIFO)

• Three QoS settings in GUI are available as follows:

• Disabled

• 802.1 priorities are set based on IEEE 802.1D-2004 Annex G User Priorities and Traffic Classes that defines seven traffic types and corresponding user priority values.

• DiffServ priorities are based on one of eight tags, each identifying one of eight traffic types and corresponding user priority values.

• The connection to the MPT-HC can be realized:

• by using two connectors:

• one DC power Supply connector to send the power supply to the MPT-HC

• one Gigabit Ethernet connector (electrical or optical) to send the Ethernet traffic and the Ethernet control frames to the MPT-HC

• or by using only one electrical Ethernet cable with the enabling of the PFoE (Power Feed over Ethernet) function (Ethernet traffic + Power Supply on the same cable).

• If the optical port has to be used, an SFP plug-in must be installed.

• If has been enabled port #1 (optical or electrical), the associated Power Supply port is #1.

• If has been enabled port #2 (optical or electrical), the associated Power Supply port is #2.

• The connection to the MPT-MC is realized by using only one electrical Ethernet cable with the enabling of the PFoE (Power Feed over Ethernet) function (Ethernet traffic + Power Supply on the same cable).

Notes:

Service Channels

Using the CT/NMS, the user can enable/disable the 64 kbit/s Service Channel interfaces. The default is disabled:

• When enabled, Service Channel interfaces 1 and 2can be configured to transport the following protocol:

• Synchronous 64 Kb/s RS422/V.11 DCE co-directional

Radio Service Channels

On each radio direction three 64 kbit/s out-of-band channels are dedicated to Service Channel transmission.

Alarm-Housekeeping

13 Alarm-Housekeeping pins are provided:

• 6 pins are configured as inputs

• 7 pins are configured as outputs.

Input alarms

The polarity of each input Alarm-Housekeeping is configurable. The state of each alarm input is configurable in order to be active, if the voltage on the input is high (open contact) or if the voltage is low (closed contact). This second option is the default value.

It is possible to assign one user label for each input.

Output alarms

By default the presence of active alarm corresponds to closed relay contact with a common wire available to the customer. By CT/NMS the polarity can be changed independently for each alarm (both normally closed and normally open contacts are available on the I/O connector).

When the power supply is down (and also when the power supply is on but the SW has not yet initialized the HW), all the relays of the outputs of the alarms/housekeeping are in the "open" state (HW default condition).

The Output Housekeeping can be managed in Manual mode only: in Manual mode the output state of each housekeeping is controlled by the operator. It is possible to assign one user label for each output.



Notes:

• Service Channels access and Housekeeping alarms are available with the optional Auxiliary peripheral unit.

• The Auxiliary peripheral unit on front panel is equipped with four connectors:

• one connector to manage the Service Channel 1

• one connector to manage the Service Channel 2

• one connector to manage the housekeeping alarms

• one connector for EOW (not used in the current release)



Notes:

EOW - Engineering Express Order Wire



Notes:

•The STM-1 unit can be used in two different working modes, addressing two different network scenarios:

• STM-1 channelized, provision card as SDHCHAN

• STM-1 transparent, provision card as SDHAC

• The STM-1 channelized interface works as a terminal multiplexer; it terminates or originates the SDH frame. It multiplexes NxE1 into an STM-1 electrical/optical line connection. The clock source can be “Loop time” or “Node time”. Typical application is a direct connection to SDH add-drop multiplexers (ADMs). STM-1 card manages one 155 Mbit/s STM1 interface and up to 63xE1. Standard VC4 mapping of lower-order E1 traffic streams to/from STM-1 is applied, that means that a VC4 directly maps up to 63xVC12 into an STM-1 signal (in turn each VC12 contains 1xE1).

• Link options include:

• 1+0 non-protected operation

• 1+1 EPS protection (available ONLY with the optical interface)

• When protection of the unit is required (1+1 EPS protection), two STM-1 units must be installed.

• Clock source from the incoming STM-1 signal can be selected as Network Element source clock. In the event the clock source is lost, clocking falls back to the internal clock or to other of any synch in options.

• In the Tx direction, the STM-1 Local Access unit processes and encapsulates up to 2xSTM-1 input lines into an Ethernet packet that is sent to the Core-E card(s).

• In the Rx direction, the STM-1 Local Access unit extracts data from the Ethernet data packets and processes the data to provide up to 2 STM-1 output lines.



Notes:

• The ASAP card is used to transport 16xE1 ATM traffic, with E1/IMA physical layer.

• The ASAP cards are unprotected (No 1+1 EPS is available).

• ATM traffic is transported within the MPR network as "special" Ethernet traffic.

• This "special" Ethernet traffic is managed by the MPR using RFC 4717 (IETF ATM PseudoWire EdgetoEdgeeEmulation, PWE3) with N-1 encapsulation format.

• ATM PW Ethernet traffic is managed by MPR is such a way to emulate the native QoS that would be applied by ATM equipment.

• VCC mode

• It is possible to transport max 48 VC for every IMA group. It is possible to manage VC switching (= VCI and VPI change)

• It is possible to assign at every VC one specific QoS. Policing and shaping at ATM level has performed VC mode only

• The VC of the same class level (CBR / UBR+ / UBR) are managed in the same radio tail than are available 3 different radio tails

• VPC mode

• It is possible to transport max 48 VP for every IMA group. It is possible to manage only VP switching (=only VPI change)

• All the VC inside the VP must have same QoS (= for ex. all CBR or all UBR)

• The radio QoS (= radio tails) and QoS ATM (=policing and shaping) are managed at VP level.

• The sum of VP + VC configured on a single ASAP card must be <128.



Notes:

•The 16xE1 ATM streams enter the ASAP unit on the front panel.

•The block diagram is divided into 3 parts:

• LIU/Framer

• Network Processor

• Confederation FPGA

•The main functions implemented by the LIU/Framer are:

• Internal termination supported: 75 ohm, 120 ohm.

• Line code supported: HDB3.

• Pulse shape: digitally programmable

• Framing to G.704 E1 signals and to CRC-4 multi-frame alignment signals.

• Detection of alarm conditions as loss of signal, loss of frame, loss of signaling multi-frame and loss of CRC multi-frame.

• The Network Processor is the heart of the ASAP card and provides the implementation of the protocols to be supported as well as data forwarding. ATM-IMA over PseudoWire, SAToP (like on the PDH card), CESoP, ML-PPP can be supported by the SW application controlling the Data Path and running on a different MIPS processor embedded on the same chip.

• The main function implemented in the confederation FPGA is the clock management.

• The right-hand side is the backplane with the 1 Gb bus shared among the other slots and hence common with the other units (PDH units and Modem units).



Notes:

Power Injector box: stand-alone box, powered through two connectors on the front providing power supply redundancy.

• The box can be mounted in a rack by means of a separate bracket.

• The bracket can support two boxes side by side.

• Height: 1.3 U.



Notes:

• Two DC connectors in the front (for box version), or power from the back panel (for plug-in version).

• Two RJ45 for the data in (DATA)

• Two RJ45 for the data + DC out (DC+DATA)

Notes:

• The ODUs include a waveguide antenna port, Type-N female connector for the ODU cable, a BNC female connector (with captive protection cap) for RSSI access, and a grounding stud.

• The ODUs, are designed for direct antenna attachment via an 9500MPR-specific mounting collar supplied with the antennas.

• ODU polarization is determined by the position of a polarization rotator fitted within the mounting collar.

• A remote ODU mounting kit is available as an option. These may be used to connect an ODU to a standard antenna, or to a dual-polarized antenna for co-channel link operation.

• ODUs are fixed for Tx High or Tx Low operation.

•Where two ODUs are to be connected to a single antenna for hot-standby or frequency diversity configurations, a direct-mounting coupler is used. They are available for equal or unequal loss operation. Equal loss is nominally 3 dB.

• Unequal is nominally 1/6 dB.

• The ODU assembly meets the ASTME standard for a 2000 hour salt-spray test, and relevant IEC, UL, and Bellcore standards for wind-driven rain.

• ODUs are frequency-band specific, but within each band are capacity-independent up to their design maximums.



Notes:

• The quadrature modulated 311 MHz IF signal from the MSS is extracted at the N-Plexer and passed via a cable AGC circuit to an IQ demodulator/modulator.

• Here the 311 MHz IF is demodulated to derive the separate I and Q signals using the 10 MHz synchronizing reference signal from the MSS.

• These I and Q signals modulate a Tx IF, which has been set to a specific frequency between 1700 and 2300 MHz, such that when mixed with the Tx local oscillator signal (TXLO) in the subsequent mixer stage, it provides the selected transmit frequency. Both the IF and Tx local oscillators are synthesizer types.

• Between the IQ modulator and the mixer, a variable attenuator provides software adjustment of Tx power.

• After the mixer, the transmit signal is amplified in the PA (Power Amplifier) and passed via the diplexer to the antenna feed port.

• A microprocessor in the ODU supports configuration of the synthesizers, transmit power, and alarm and performance monitoring. The ODU microprocessor is managed under the NCC microprocessor, with which it communicates via the telemetry channel.

• A DC-DC converter provides the required low-voltage DC rails from the -48 Vdc supply.

• In the receive direction, the signal from the diplexer is passed via the LNA (Low Noise Amplifier) to the Rx mixer, where it is mixed with the receive local oscillator (RXLO) input to provide an IF of between 1700 and 2300 MHz. It is then amplified in a gain-controlled stage to compensate for fluctuations in receive level, and in the IF mixer, is converted to a 126 MHz IF for transport via the ODU cable to the MSS.

• The offset of the transmit frequencies at each end of the link is determined by the required Tx/Rx split. The split options provided are based on ETSI plans for each frequency band. The actual frequency range per band and the allowable Tx/Rx splits are range-limited within 9500MPR-E to prevent incorrect user selection.

• A power monitor circuit is included in the common port of the diplexer assembly to provide measurement of transmit power. It is used to confirm transmit output power for performance monitoring purposes, and to provide a closed-loop for power level management over the specified ODU temperature and frequency range.



Notes:

The ODU mounts directly to an Antenna: Non-protected.



Notes:

• ODUs can be installed separately from its antenna, using a remote-mount to support the ODU, and a flexible-waveguide or coaxial cable to connect the ODU to its antenna:

• a flexible waveguide is required.

• The remote mount allows use of standard, single or dual polarization antennas.

• The mount can also be used to remotely support a protected ODU pairing installed on a coupler. The coupler connects to the remote mount assembly in the same way as an ODU.

• The remote mount clamps to a standard 112 mm (4”) pole-mount, and is common to all frequency bands. Figure shows an ODU installed on a remote mount.

• Flexible waveguides are frequency band specific and are normally available in two lengths, 600 mm (2 ft) or 900 mm (3 ft). Both flange ends are identical, and are grooved for a half-thickness gasket, which is supplied with the waveguide, along with flange mounting bolts.



Notes:

• Table lists the antenna port flange types used with the ODU300, plus their mating flange options and fastening hardware for remote mount installations.

• UDR/PDR flanges are rectangular; UBR/PDR flanges are square.

• On the ODU, the two flange styles are:

• UDR. 6-hole or 8-hole (6/8 bolt holes depending on frequency range/waveguide type), flush-face flange with threaded, blind holes.

• UBR. 4-hole flush-face flange with threaded, blind holes.

• The corresponding mating flange styles are:

• PDR. 6-hole or 8-hole flange with gasket groove and clear holes.

• PBR. 4-hole flange with a gasket groove and clear holes.

• All fastening hardware is metric.



Notes:

For all set-ups, one ground wire must be installed to ground the ODU.

Notes:

• The MPT-HC is broken down into the following sections:

• Common Belt section. This section is Frequency independent, and all the features relevant to this unit are common to all the MPT RF options.

• RF section that is frequency dependent.

• The MPT-HC interface is based on a Gb Ethernet, that can be either optical or electrical depending on the needs and the cable length. If the optical port has/have to be used (data and/or RPS port), the corresponding SFP plug-in must be installed by opening the Cobox.



Warning: A waterproofing tape is glued on the waveguide of the MPT-HC. It must never be removed.

Notes:

§ The DC Extractor, installed close to the MPT-HC, allows to interconnect the MSS and the MPT-HC with a single electrical Ethernet cable by using the “Power Feed over Ethernet” solution (Ethernet traffic and Power Supply on the same cable).

§ The DC Extractor then separates the Power Supply from the Ethernet traffic, which are separately sent to the MPT-HC.

§ The two cables, interconnecting the DC Extractor to the MPT-HC (the Power Supply cable to be connected to the DC Out connector of the DC Extractor and Ethernet cable to be connected to the Data Out connector of the DC Extractor), are provided, already terminated (2 m long), with the DC Extractor itself

Notes:

Two mechanical solutions are adopted:

• With embedded diplexer for cost optimization, where the branching (diplexer) is internal to the MPT-HC V2 cabinet; this type of unit is identified by one Logistical Item only.

• With external diplexer: due to a high number of shifters the diplexer is external for the flexibility of the shifter customization, where MPT-HC V2 is composed by two independent units: the BRANCHING assembly (containing the diplexer) and the RF TRANSCEIVER assembly (containing the RF section); each of this type of MPT-HC V2 is identified by two Logistical Items, one for the BRANCHING assembly and another for the RF TRANSCEIVER assembly. To read the BRANCHING assembly identification label it is necessary to separate the BRANCHING assembly from the RF TRANSCEIVER assembly.



Notes:

• The common belt section is frequency-independent. It is the digital section of the MPT-HC V2/MPT-XP.

• There are two architecture types for the RF section, the differences between these two architectures are on the Rx side:

• For 7/8 GHz, there are two frequency conversions between RF input frequency and baseband frequency

• For all other bands, there are three frequency conversions

• The power comes from office power. Input voltage range is -28 to -58 Vdc.

Notes:

• The Ethernet interface traffic is bridged across the link via an embedded switch. The SONET/SDH traffic is handled separately within the radio and does not pass through the internal switch.

• The SONET/SDH and Ethernet traffic are aggregated within the radio unit for transmission over the air to the far end of the link.

• Depending on configuration, the available Ethernet bandwidth can exceed 1000Mbps. To utilize the full Ethernet capacity, the radio contains an internal Primary and Secondary Ethernet radio interface. This allows copper or Ethernet SFP interfaces to be assigned to the Primary or Secondary channel within the radio. An internal radio link aggregator handles this functionality.

• The portion of the radio bandwidth that is not used by SONET/SDH is available for use by Ethernet as shown in the table below.

Notes:

In the figure Ethernet port 2 of one MPT-HCV2/MPT-XP is connected to Ethernet port 2 of the second MPT-HC V2/MPT-XP.



Notes:

• MPT-HCV2/MPT-XP supports a further embedded functionality called "Enhanced RPS". Enhanced RPS is a frame-based protection mechanism, aimed to reach a quick reaction time and increasing significantly the quality of the radio interface in the Rx side.

• It assumes the alignment between the 2 received radio channels and it is based on frame by frame selection of the "best" frame between the frames received from the Main and the Spare radio channel.

• The Enhanced RPS assumes that the "classical" RPS criteria are used to give indication about the "preferred" channel, whose frame has to be selected, when the frame-based choice between the 2 streams is not possible (e.g. due to the frame alignment error).

• The Enhanced RPS switching criterion depends on the presence of errors in the decoded LDPC word.



Notes:

Where there is a cross configuration (EPS on Spare & TPS on main), HSB (TPS) will switch and align with EPS position, if there is an inter-MPT coupling link failure.



Notes:

• This function is implemented by installing the “RPS+XPIC” external module).

• The actual improvement will depend on the native discrimination provided at antenna alignment, and any reduction of this discrimination caused by atmospheric effects (fading).

• XPIC typically provides 20 dB improvement in polarization discrimination.



Notes:

• Since there is no coupling link in the current release the TPS Operator Commands are not supported.

• Only Operator Commands for EPS are supported.

• MPT-MC supports a further embedded functionality called "Enhanced RPS". Enhanced RPS is a frame-based protection mechanism, aimed to reach a quick reaction time and increasing significantly the quality of the radio interface in the Rx side.

• The Enhanced RPS assumes that the "classical" RPS criteria are used to give indication about the "preferred" channel, whose frame has to be selected, when the frame-based choice between the 2 streams is not possible (e.g. due to the frame alignment error).

• The Enhanced RPS switching criterion depends on the presence of errors in the decoded LDPC word.



Notes:

All the switching criteria coming from both the Core units, are available (via back panel) to each peripheral in order to allow to each logic to take the same decision.



Notes:

In case of stand-by Flash Card realignment in progress, the application SW refuses/removes a manual switch command.
