Introduction

Set the Clock Source

This chapter describes how to configure 2- and 4-wire 56/64 kbps ser- vice modules. These tasks are described:

zSet the Clock Source

zSet the Network Line Speed

zEnable Scrambled Data Coding

zChange Between DDS and Switched Dial-Up Modes

zEnable Acceptance of a Remote Loopback Request

zSelect a Service Provider

In most applications, the CSU/DSU should be configured with the service-module 56k clock source line command. Fo back-to-back configurations, use the internal keyword to config- ure one CSU/DSU and use the line keyword to configure the othe CSU/DSU.

Configure the clock source for a 4-wire 56/64-kbps CSU/DSU mod- ule:

service-module 56k clock source {line internal}

Do not use any form of this command to revert to the default clock source, which is the line clock.
