H801CSPA Board
The H801CSPA is a CESoP service processing board. It supports the
structure-agnostic TDM over packet (SAToP) processing of 64
channels of E1 signals.
Overview
The H801CSPA board supports the following functions:
SAToP processing of 64 channels of E1 signals
8 kHz clock channel from the H801CSPA board to the backplane, which
is used to transmit the clock signals recovered from the service to
the control board
Automatic power shutdown in case of a high temperature
Parameters
Power Consumption and Maximum Frame Size of Boards
You can query power consumption, maximum frame size, and normal
operating temperature of all boards.
lists the power consumption and maximum frame size of boards. "-"
indicates N/A.
The operating temperature of all the boards is -40°C to +65°C. The
lowest board startup temperature is -25°C.
NOTE:
The power consumption of the board is tested in the following
conditions:
Working voltage: -53.5 V DC.
Ambient temperature: 25 °C.
Static power consumption: All ports do not carry any loads.
Specifically, users under POTS ports hang up phones, xDSL ports are
deactivated, and optical modules are not installed on optical ports
Maximum power consumption: All ports fully carry loads. However,
only 25% users under POTS ports concurrently pick up phones and the
feeding current is 20 mA.
The board power consumption slightly varies with the power module
configured for the board and discreteness of components.

Working Principle
Figure 1 Working principle of the H801CSPA board
The basic working principle of the H801CSPA board is as follows:
The control module loads the board software, controls the running
of the board, and manages the entire board.
The service processing module implements the switching of the
services.
The DSP module implements the SAToP algorithm function.
The power module draws -48 V power from the backplane and converts
the power into working power for each functional module of the
board.
The clock module provides clock signals for each functional module
of the board.
