The H802EDTB board provides two 8-channel E1 ports and one 16-channel SHDSL port and
its basic working principle is as follows:
l The control module controls the board, and loads and configures the service processing
logic. The LocalBus and MII interfaces are for the service processing module.
l The service processing module implements switching of the time division multiplexing
(TDM) timeslots and IP packets distribution inside the board, configures and controls the
E1 ports, and provides the HDLC channel for its communication with the control board.
In addition, the service processing module supports packet filtering, traffic control, and
encryption.
l The E1 interface module provides 16 channels of E1 access services and signal
conversion.
