Description

Huawei SSN1D75S Board is 32xE1 / T1 electrical interface switch outboard (75 ohms).It is used to input and output 32 E1 electrical signals. It needs to be used with PQ1 board. The Huawei D75S board consists of interface modules, switch matrix modules, and power access circuits.

Huawei SSN1D75S Board Product Overview

Huawei SSN1D75S Board is a PDH interface switching board. It is used on OptiX OSN series equipment to provide signal input and output interfaces for PDH processing boards. At the same time, when the corresponding PDH processing board is configured with TPS protection, an interface switching board is required to complete the TPS protection.

The D75S receives and transmits 32xE1 electrical signals.

The D75S must work with the PQ1.

The D12S needs to configure 4*E1 subscriber cable.

SSN1D75S is a PDH interface switching board, receives and transmits 32xE1 electrical signals, can be used on Huawei OSN 1500B, OSN 2500, OSN 3500, OSN 7500 when working with PQ1. SSN1D75S part number is 03026727, model name is D75S.

Huawei SSN1D75S Board Product Features

  • The D75S board is used to input and output 32 E1 electrical signals. It must be used with the PQ1 / PD1 board.
  • Working principle and signal flow
    The D75S board consists of an interface module, a switch matrix module, and a power access circuit.
  • Interface module
    The interface module completes the reception and transmission of E1 electrical signals.
    Switch Matrix Module
  • In the receiving direction, the switch matrix module accesses the signal from the interface module and selects the output direction of the signal according to the TPS protection control signal of the crossbar. When TPS does not occur, the switch matrix module sends signals to the PQ1 / PD1 board; when TPS occurs, the switch matrix module sends signals to the protection board for bridging.
  • In the transmitting direction, the working process of the switch matrix module is the inverse process of its receiving direction.
  • Power access circuit
    The power supply circuit provides the required DC voltage for all modules of the board
