Disconnect the RJ-48 (8-wide) connector at the appropriate interface point and connect the loopback jack in series with the DS1 span. See the figure through the figure.
Plug the H600-383 cable from the ICSU into the female connector on the loopback jack.
Plug the male connector on the loopback jack cable into the network interface point.
Note:
Do not remove the loopback jack after installation. This is not a test tool and should always be available to remotely test a DS1 span.
