SL91MD1,MD1,Huawei RTN 900 Series IDU Board

Huawei RTN 900 Series IDU Board SL91MD1 Overview

The MD1 is a 32xSmart E1 service processing board

The functional version of the MD1 is SL91.

ML1/MD1 boards transmit E1 services on OptiX RTN 950 NEs that transmit E1-carried ATM/CES services in PWE3 mode. The selection of boards depends on desired port quantities.

The ML1/MD1 board is used to:

Transmit CES/ATM E1 services in PWE3 mode.
Allow an MPLS tunnel to traverse a TDM network

An MD1 receives and transmits 32 channels of E1 signals.

There are indicators and E1 ports on the front panel of the ML1/MD1.

The ML1/MD1 can be inserted in Slots 1-6, which have consistent logical slot numbers on the NMS.

The port impedance of the ML1/MD1 can be identified by the board feature code of the bar code. A board feature code refers to the number next to the board name in a bar code.
