DS1/T1 CPE loopback jack
This chapter provides information on how to install and use a DS1 loopback jack
to test the DS1 span between the Avaya Media Server or Gateway and the
network interface point. The loopback jack is required when DC power is at the
interface to the integrated channel service unit (ICSU).
NOTE:
Do not remove the loopback jack after installation. It should always be
available for remote tests of the DS1 span.
NOTE:
For G700 Media Gateway systems, the channel service unit (CSU) is
integrated within the MM710 board. This means that there is no need for a
separate external device. For earlier media gateway systems, the integrated
channel service unit (ICSU) — also known as the 120A2 — is a separate
device that plugs into the back of the media gateway.
For G700 Media Gateway systems, the loopback jack isolates the MM710
internal CSU from the DC power and properly loops the DC span power.
Installing a loopback jack
You can install a loopback jack with or without a smart jack.
With a smart jack
Install the loopback jack at the interface to the smart jack, if possible. This position
provides maximum coverage of CPE wiring when remote loopback tests are run.
