SETTING UP THE
CAMPUS-RS SYSTEM
There are three sets of configuration options that must be set for the
Campus-RS Fractional Interface Card to operate:
• the HDSL mode and rate
• the Timing Source
• The Transmit Clock
Depending on the requirements of your network, you may be able to use the
default settings for one or more of these options. If so, you can skip the
relevant section(s). With the default settings, the Fractional Interface Card is
set to operate:
• with the HDSL Operating Mode set to Standard Mode
• with the Standard Mode HDSL Rate set to T1 over two loops
• with the Timing Source option set to Internal
• with the Transmit Clock option set to External, so the SD signal is
sampled based on TT input
See “Default Settings” on page A-2 for a list of all configuration option
default settings.
The steps in this chapter set these options through the menu buttons and LCD
on the front of the desktop unit or the Campus-Star Campus Management
Unit (CMU). You may also use an ASCII terminal to set these options, as
described in Chapter 5, “Configuring with an ASCII Terminal.”
