MCMU- Marker and Cellular Management Unit

• The Marker and Cellular Management Unit (MCMU) controls and supervises the Bit Group Switch and performs the hunting, connecting and releasing of the switching network circuits.

• The cellular management functions of the MCMU are responsible for cells and radio channels that are controlled by the BSC. The MCMU reserves and keeps track of the radio resources requested by the MSC and the handover procedures of the BSC.

• MCMU also manages the configuration of the cellular network.

• Redundancy 2N

BCSU- BSC Signalling Unit

• The BSC Signalling Unit (BCSU) performs those BSC functions that are highly dependent on the volume of traffic.

• Consists of two parts, which correspond to the A and Abis interfaces

• Packet Control Units (PCUs) are housed in the same cartridge.

• The A interface part of the BCSU is responsible for performing all message handling and processing functions of the signalling channels connected to it

• Performing the distributed functions of the Message Transfer Part (MTP) and the Signalling Connection Control Part (SCCP) of SS7

• Controlling the mobile and base station signalling (Base Station Subsystem Application Part, BSSAP)

• The Abis interface part of the BCSU controls the air interface channels associated with transceivers (TRXs) and Abis signalling channels.

• The handover and power control algorithms reside in this functional unit.

• Redundancy N + 1

OMU- Operating and Maintenance Unit

• OMU is an interface between the BSC and a higher-level network management system and/or the user. The OMU receives fault indications. It can produce local alarm printouts to the user or send the fault indications to NetAct

• In a fault situation, the OMU automatically activates appropriate recovery and diagnostics procedures. Recovery can also be activated by the MCMU if the OMU is lost.

• The OMU consists of microcomputers and contains I/O interfaces for local operation.

• The tasks of the OMU can be divided into five groups:

• traffic measurement functions

• maintenance functions

• system configuration administration functions

• system management functions

• LAN topology management

Flexi BSC mechanical design

• Welded frame structure designed on IEC, EN, ETSI, UL and Telcordia recommendations with advanced features in terms of safety, protection against interference, stability and durability

• Easy transportability and suitability for installations with normal room height as well as with completed internal cabling

• Due to the simple mechanical structure with relatively few components, the equipment cabinets are easy to assemble and disassemble when necessary

• The Flexi BSC includes forced cooling system to ensure optimum ambient temperature for its functional units


Flexi BSC site solution

Fast installation and very easy expansion

No special site requirements

Simplified cabling with compact one cabinet design

Low site costs ensured with small size and installation easinessLow site costs ensured with small size and installation easiness

EXAMPLE Flexi BSC REMOTE SITE:

Raised floor installation option

Cabling CabinetIn equipment rooms with raised floor the Cabling Cabinet is used with each Flexi BSC cabinet for cabling external cables under the floor

Side Cabling Conduit, SCCThe SCC can be used to separate power cabling from the external PCMs cabled to cabling cabinet

The SCC can be installed on either side of the BSC


NetAct link options in Flexi BSC

LAN (Ethernet) interface (recommended)• LAN Ethernet interface according to IEEE802.3 for faster

access

• This is the default NetAct link interface

• Connected via CPRJ45 panel on top of the cabinet

Digital X.25 interface, AS7-D (PCM time-slot-based O & M interface via A Interface, G.703)

• An O&M interface via transcoders and transmission equipment

• Network management interfaces in PCM time slots

• Suitable only small BSCs with under 1000TRX

The LAN interface redundancy is implemented by providing a redundant LAN connection

The digital X.25 interface can optionally be redundant by using duplicated units


BSC peripheral options

Line Printer, LPT

A printer can be connected to the OMU. The interface complies with the ITU-T Recommendation V.24.

External Alarm Unit, EXAU

The alarm lamp panel shows the BSC HW alarms and it can be installed to a place where the observations of alarms can be noticed easily.

Visual Display unit, VDU

A visual display unit is used as a user interface at BSC site. By using a VDU terminal, the

user can perform normal operational functions, using MML commands and diagnostic tests on various units.

Detailed Flexi BSC power consumption (RG20)

Typical power consumption of the Flexi BSC is below 1 W/TRX and depends on top of TRX capacity on:

• PS Capacity (0 – 5 PCU2-E per BCSU) • Interface unit amount (see below)

Power consumption of the base configurations:

• Additional power consumption from external interface units• ~12 W per ET16 unit (0 – 50 units)• ~26 W per ETS2 unit (0 – 18 units)• ~21 W per ETIP1-A unit (0 – 18 units)• ~80 W per ETP active (0 – 6 units)• ~70 W per ETP spare (0 – 6 units)• ~60 W per ETP-A (0 – 4 units)

Please note: Site power distribution is recommended to be dimensioned as defined in Installation Site Requirements document (for max. 4.0 kW)
