Monitor jacks are available on the rear System Processor modules and can
be used monitor DS-0s of multiple DS1s (e.g., ISDN D channels). The
DS-0s are typically ISDN D-channels or SS7 signaling channels, although
a single DS1 could be monitored. However, ISDN D-channels and SS7
signaling channels cannot be monitored on the same DS-1. The test jacks
and the DS-0s to be monitored, which must be on the same IOM, are
selected with TL1 commands.
Because there are two pairs of jacks, two different DS-1s can be
monitored. J7, labeled “I”, allows the user to input a signal and monitor it
using J8, labeled “O”. J9 is not used and J10, which is labeled “O”, is
used as a monitor jack. Refer to
