GPON board - GPBC/GPBD
 
● Control module: complete the software loading, operation control, management and other functional
● Exchange modules of the board: realize the aggregation of 4 (8) GPON port signals
● Interface module: realize the mutual conversion of GPON optical signal and Ethernet message ● Power module: provide working power for each functional module in the single board
● Clock module: provide working clock for each functional module in the board
 
EPON service board I EPBC / EPBD
 
Main functions:
EPON (Ethernet passive optical network) access board and terminal ONU (optical network unit) equipment cooperate to realize OLT function of EPON system.
External interface:
Each EPBC panel provides 4 EPON SFP pluggable optical modules, and each EPBD panel provides 8 EPON SFP pluggable optical modules
 
● Control module: complete the software loading, operation control, management and other functional
● Exchange modules of the board: realize the aggregation interface module of 4 (8)
● EPON port signals: realize the mutual conversion of EPON optical signal and Ethernet message
● Power module: receives - 48ν power supply from the backplane, converts the cost of the working power of each functional module of the board
● Clock module: provides the working clock for each functional module of the board
 
Special line service board - CSPA
 
Main functions  
•CESoP business processing board, providing SAToP (structure agnostic TDM over packet) processing of 64 E1 channels
• Support the 8K clock channel to the backplane, and send the clock recovered from the service to the main control board.
• One 10GE interface to each main control board
• CSPA completes the conversion from native TDM to SATOP, and the panel does not come out of the interface  
• need to be used with SPUB
 
Special line business board - TOPA
 
Major function
T0PA is a packet switching network transmission time division multiplexing service board, which realizes the service uplink through the daughter board.
Support native TDM function (configure NH1A/O2CE button board) and CESoP function (configure EH1A / CSSA button board).
Support TDM signal E1 interface uplink (configure NHIA / EH1A gusset board)
Support TDM signal STM-1 optical port uplink (configure O2CE / CSSA gusset plate)
