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
.
