DS1 Test Jacks
There are two pairs of bantam jacks, label “I” and “O”. Refer to
. Typically, these jacks are used to monitor DS0s of multiple
DS1s (e.g., ISDN D channels). Because there are two pairs of jacks, two
different DS1s can be monitored. The top connector, labeled “I”, allows
you to input a signal and monitor it using the connector beneath, labeled
“O”.
These jacks allow you to monitor a DS-1 or DS-0s of multiple DS-1s
entering or leaving the Plexus 9000. The DS0s are typically ISDN
D-channels or SS7 signaling channels, although a single DS-1 could be
monitored. However, ISDN D-channels and SS7 signaling channels
cannot be monitored on the same DS1. The DS-0s to be monitored must
be on the same IOM and are selected with TL1 commands. The test jacks
are also selected with a TL1 command.
