H801TOPB Board

The H801TOPB is a TDM traffic over PSN board. It provides two STM-1 ports for transmitting TDM services to the upstream.

Overview

The H801TOPB board supports the following functions:

Native TDM function

CESoP function

TDM signal upstream transmission through two STM-1 optical ports

Intra-board and inter-board 1+1 port protection

Automatic shutdown in times of high temperatures

Specifications

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 H801TOPB board

The basic working principles of the H801TOPB board are as follows:

The control module loads the board software, and controls and manages the entire board.

The service processing module allocates the GE bus of the backplane and processes signals.

The interface module converts signals.

The power module supplies power to other function modules of the board.

The clock module provides the working clock signals for other function modules of the board.

The service processing procedure of the H801TOPB board is as follows:

In the upstream direction, GE signals from the backplane travel trough the interface module and are converted into the TDM frames. Then the TDM frames are transmitted upstream.

In the downstream direction, the interface module receives signals from the TDM line and converts the signals into the GE packets. Then the service processing module processes the GE packets and forwards them to the backplane bus. The backplane bus transmits the GE packets to the control board and then the control board allocates the GE packets to respective service boards
