DSU DIM Installation

Troubleshooting DSU DIM Installation

Introduction

Some of the potential installation problems are listed below:

Improper port connection of the EIM

Improper telco interface connection

DSU DIM not connected in DTE configuration

Processor card jumpers not in HS1 mode

DSU option software not operational

DSU port clock source option not correct

No signal from telco interface

CTP

The following information can be derived from the control terminal to aid in

Troubleshooting

troubleshooting.

 

 

 

 

 

Node Statistics

Used to verify that the software is a version which contains

 

 

the DSU option modifications. It also shows if the DSU DIM

 

 

is recognized by the software.

 

 

 

 

Port Statistics

Used to verify that data is being sent without error. Error

 

 

counts may denote an error in clocking mode configuration.

 

 

It also shows if the DSU DIM is recognized by the software.

 

 

 

 

Monitor

Input/output signals can be used to determine if the DSU

 

 

option is in a loopback mode requested by the remote end.

 

 

This would be an explanation for the inability to send data.

 

 

Continuous bipolar violations would also indicate the remote

 

 

system is out of service.

 

 

 

 

DSU Internal

Failure of this loopback mode would indicate that the EIM

 

Loopback

module is not connected.
