DS1/T1 CPE loopback jack

If the smart jack is not accessible, install the loopback jack at the extended demarcation point.

If there is no extended demarcation point, install the loopback jack directly at the network interface point as shown in Figure 24 and Figure 25.

If there is an extended demarcation point and the smart jack is not accessible, install the loopback jack as shown in Figure 26 and Figure 27.

If there is an extended demarcation point, but the smart jack is accessible, install the loopback jack as shown in Figure 28 and Figure 29.

1.To install the loopback jack, simply disconnect the RJ-48 (8-wide) connector at the appropriate interface point and connect the loopback jack in series with the DS1 span. See Figure 24 through Figure 33.

2.Plug the H600-383 cable from the ICSU, or from the MM710, into the female connector on the loopback jack.

3.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.

Without a smart jack

Install the loopback jack at the point where the cabling from the ICSU plugs into the dumb block. If there is more than one dumb block, choose the one that is closest to the Interface Termination feed or the fiber MUX to provide maximum coverage for loopback jack tests. Refer to Figure 30 through Figure 33.
