control cabinet and resource cabinet. The cabinet mounting
includes mounting the BSC cabinet and its accessories, and
mounting the server cabinet and its accessories.
4. Installing the Power system and Grounding system
Stable and reliable power and grounding systems are the
basis for the safe running of the BSC. The installation flows
and precautions for the power and grounding systems of the
BSC cabinet, server cabinet and plug-in boxes, including:
Procedure for installing the power system of the BSC
Procedure for installing the grounding system of the BSC
The BSC has two types of power supplies. One is the -48 V
DC power supply for the BSC and alarm box, and the other is
the 220 V AC power supply for the server, router, Ethernet
switch, and background terminals.
For different power supplies, the power cables and their
installation procedures and precautions are different.
The BSC employs a group of four separate busbars to
directly provide power supply and grounding points for the
backplanes on various layers.

-48 V GND
Protection Ground (PGND)
5. Installing internal Cables
For a new BSC system, the internal cables of the cabinet
usually have already been connected and tested before
delivery. In installation, you only need to check if their
connections comply with the cabling requirements.
For a BSC in capacity expansion, the cabinets should be
installed according to the expansion cabinet and board
conditions, and then the boards are plugged and the internal
cables of the BSC are connected. The installation of the
internal signal cables of the cabinet need straight
screwdrivers and cross screwdrivers.
Types of internal cables:

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 board configuration principles are:
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
46

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.
