The Enhanced Integrated CSU is for use in the United States of America with
1.544 Mbps DS1 service. For further details on the 120A1 CSU Module refer to
DEFINITY Communications System Generic 1, Generic 2, and Generic 3 V1 and
V2 - Integrated CSU Module Installation and Operation.
The UDS1-BD and 120A1 CSU Module support on-demand loopback tests that
assist in the detection of faults between the UDS1-BD circuit pack and the CSU
Module, between the Integrated CSU and the optional Customer Premises
Loopback Jack, or between the Integrated CSU and remote CSU. These
loopback tests are explained in detail later in this UDS1-BD MO, but
Figure 56
gives a high level overview of the loopback points.
