H802DSRE
The basic working principle of the H802DSRE board is as follows:
l The CPU module controls calls, processes call protocols, and packages voice data.
l The ISDN service processing module processes the ISDN service of the board, including
extracting signaling and switching data.
l The interface module converts between the media independent interface (MII) interface
and the GE interface.
l The power module supplies power to each functional module of the board.
l The clock module provides clock signals for each functional module of the board.
The service process is as follows:
l In the upstream direction, service data is transmitted to the board through the ISDN
service processing module and is packaged by the CPU module. The interface module
