The board configuration principles are:

Use of more than two BUSN resource shelves requires level 1 switching subrack configuration.

Use of BPSN backplane requires level 1 switching subrack configuration, two PSN4V switching boards, at least two GLIQV line cards, and two UIMC two boards.

GLIQVs follow configuration in pairs on consecutive slots starting from the left most. Each pair supports four BUSNs.

UIMC boards work in the active/standby mode and are always inserts into Slots 15 and 16 in the Level-1 switching shelf.

PSN boards also work in the active/standby mode and are always inserts into Slots 7 and 8.

GLIQV boards can be inserted into 1 to 6 slots and 9 to 14 slots.

The CHUB is control flow convergence centre, and needs when system capacity is more than 2 x BUSN + 1 x BCTC. Each pair of CHUB boards provides control plane access capability of 21 BUSN or BPSN subsystems, and inserts into control shelf slots 15 and 16. Excess system capacity exceeding capacity of a pair of CHUBs requires configuration

Control Shelf



of an additional pair of CHUBs. The two BCTCs where CHUBs reside follow trunk mode connection. UIMC FEC43–46 connects with the first pair of CHUBs to UIMC FEC7–FEC10 of the BCTC shelf that has the second CHUB pair.

The control shelf contains pair of CLKG boards, one is active and other is standby. The CLKG board inserts into control shelf slots 13 and 14, and allocates system clocks to level-1 switching shelf and resource shelves through cables.

The OMP board is a communication control centre, performs specific processing function. One BSC subsystem needs only one pair of OMP boards that are inserts into control shelf slots 11 and 12.

UIMC boards work in active/standby mode and inserts into control shelf slots 9 and 10.
