3.9 CSMB BoardThis section describes the function, principles, front panel, port, pin assignment, andspecifications of the CSMB board.

OverviewThe CSMB board is a 16-port ADSL/ADSL2+ and POTS combo service board, with built-insplitter.




l The ADSL/ADSL2+ service communicate with the broadband control board through thebackplane. The broadband control board forwards the services from the CSMB board tothe IP network.

l The POTS service communicates with the narrowband control board through HW bus. Thenarrowband control board forwards the services upstream through V5 or MG interface.

The CSMB board has the following functions and features:l The ADSL service and the POTS service do not affect each other either on services or on

management.l Ports 7 and 8 support the reversal polarity.l The circuit and loop line tests are supported by configuring the CSMB board with a test

relay board.The ASL board resides in slots 635 of the HABA shelf, slots 617 of the HABC or HABDshelf, slots 1835 of the HABF shelf, and slots 611 of the HABL shelf.Figure 3-29 shows the external connections of the CSMB board.

Figure 3-30 Principles of the CSMB board

The CSMB board consists of:l Protection module, which protects the service board in case of loop line abnormality,

including power line touching and lightning.l Splitter module, which splits POTS signals and ADSL2+ signals from the mixed signals.l Driving module, which magnifies driving of downstream services.l Service process module, which accesses ADSL2+ services.l Convergence module, which forwards the customer data upstream to the control board or

sends the data from the control board downstream to the customer.l Control module, which performs service board startup, management, control and serial port

communication.l Power module, which provides power supply of 48 V, 5 V, 3.3 V and 1.5 V to the board.l Relay module, which performs circuit/loop line test through switchover of narrowband

relay.l Main control module, which communicates with NOD board and detects line board status

and controls the COMBO chip on board.l COMBO module, which provides BORSCHT function to 16 pairs of analog subscriber

lines and realizes the switchover and assignment of time slots.l SLIC module, which performs feed detection, offhook detection and 2/4 line switchover.

OverviewThe DSL board is an 8-port digital line board that provides eight 2BD ports.The DSL board provides: Standard ISDN BRA services, TA128 semi-permanent connectionmode, MTA access mode and U-port transparent transmission access mode.



The DSL board has the following functions and features:l The eight U ports on the DSL board can be configured to different working modes.l The DSL board can provide the power supply to customer terminals. It controls the DC

power supply of eight ports through the remote power control circuit.l The provision of power supply can be set by ports through configuration at the background.l The power supply circuit has the functions of over-current detection and automatic

protection. The automatic recovery of power supply can be implemented through thesoftware control.

The DSL board resides in slots 6-35 of the HABA shelf, slots 617 of the HABC or HABDshelf, slots 1835 of the HABF shelf, and slots 610 of the HABL shelf.Figure 3-41 shows the external connections of the DSL board.

3.12 ADRI BoardThis section describes the function, principles, front panel, port, pin assignment, andspecifications of the ADRI board.

OverviewThe ADRI board is a 32-port ADSL/ADSL2+ service board, with a built-in ADSL over POTSsplitter to access the ADSL over POTS service. The ADRI board communicates with thebroadband control board through the broadband subtending serial port. The broadband controlboard forwards the broadband services to the IP network.The ADRI board resides in slots 635 of the HABA shelf, slots 617 of the HABC or HABDshelf, slots 1835 of the HABF shelf, and slots 611 of the HABL shelf.Figure 3-43 shows the external connections of the ADRI board.

The ADRI consists of:l Control module, which initiates controls chips on the board.l Bus conversion module, which converts between backplane bus and broadband bus.l Digital process module, analog front end module and line amplifier module, which

performs the ADSL2+ service coding/decoding, analog/digital conversion and line driving.The uplink port connects to the broadband bus of the backplane.

l Splitter module, which splits POTS signals from the mixed signals and accesses them tothe corresponding service process boards.
