H802SHGM Board Description
The H802SHGM board is a 32-port SHDSL.bis service board. It
works with the SHDSL transceiver unit-remote (STU-R) to provide
32-channels of SHDSL services.
Feature and Specifications
Please refer to "SHDSL Service Board Comparison".
Parameters
Please refer to "Power Consumption and Maximum Frame Size of
Boards".
Working Principle
Figure 1 Working principle of the H802SHGM board
The basic working principle of the H802SHGM board is as follows:
The control module loads the board software, controls the running
of the board, and manages the entire board.
The protection module protects and isolates the board from
lightning strikes. The DC block isolates the direct current. The
protector protects the high voltage.
The forwarding module processes the signals. After being processed
by the control module, the signals are transmitted to the backplane
bus through the interface of the backplane.
The interface module inputs, outputs, and converts the signals.
The power module supplies power to each functional module of the
board.
The clock module provides clock signals for each functional module
of the board.
The MELT module provides the MELT test function for digital
subscriber lines.
The service process is as follows:
In the upstream direction, the interface module transmits
subscriber line signals to the forwarding module. The forwarding
module reorganizes the cell flow into ATM/PTM packets, encapsulates
the ATM/PTM packets into IP packets, and performs CAR on the IP
packets. Controlled by the logical switch, the IP packets are
transmitted to the backplane bus through the backplane interface.
In the downstream direction, the forwarding module decapsulates the
IP packets from the backplane bus, performs CAR on the IP packets,
reorganizes the IP packets into ATM/PTM packets, and transmits the
ATM/PTM packets to the interface module. The interface module
converts the ATM/PTM packets into analog signals and transmits the
signals to subscriber lines.
