Installation Procedures
The following procedures provide step-by-step instructions for installing the
CSU and the ISDN Interface. The ISDN procedure that you should use
depends on the type of system you have and the number of ISDNs you are
installing.
Installing the CSU
The following instructions explain how to install the CSU. See “CSU
Equipment” on page 1-9 for specifications on CSUs and CSU cabling.
Note: The CSU can be powered locally or through the CO line. Also, a
locally powered CSU should be connected to an Uninterruptible Power
Supply (UPS) to provide battery backup in case of AC power failures.

side of the CSU, as shown in Figure 2-1.
