7.5.8 CHANGING COMMON MODULE SETUP PARAMETERS
The setup of a CM4 Common Module can be changed by issuing SET commands with the appropriate
parameter names and values. For example, to set line code to AMI in a terminal multiplexer with an
address of 11, issue the following command:
11:TERM:SET:FAST=ON;
Table 7-4 lists the CM4 setup parameters that can be changed remotely.
