DS1 and E1 Input Module Default Settings
424 SSU-2000 User’s Guide 12713020-002-2 Revision D – April 2004
DS1 and E1 Input Module Default Settings
The DS1 Input Module and E1 Input modules maintain factory default and current
user configuration information in nonvolatile memory. This information is retrieved at
power up and is modified by commands from the Communications module.
When the current user configuration cannot be used, the Input module settings
automatically revert to factory defaults. Table E-4 lists factory default settings and
ranges for all DS1 Input module or E1 Input module software parameters.
