●
If there is no extended demarcation point, install the loopback jack directly at the network
interface point as shown in
Figure 37 .
●
If there is an extended demarcation point and the smart jack is not accessible, install the
loopback jack as shown in
Figure 38 .
●
If there is an extended demarcation point, but the smart jack is accessible, install the
loopback jack as shown in
Figure 39 .
To install the loopback jack with a smart jack
1. 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 37 through Figure 39 .
2. Plug the H600-383 cable 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:
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.
Installing a loopback jack without a smart jack
Use one of the following installation methods:
●
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 40 and Figure 41 .
