DS1 CPE loopback jack (T1 only)

Using the DS1 CPE loopback jack, a technician can test the DS1 span between the system and the
network interface point. The loopback jack is required when DC power appears at the interface to the
Integrated Channel Service Unit (ICSU). The loopback jack isolates the ICSU from the DC power and
properly loops the DC span power.
