61200051L1-1D
The ISU 2x64 must be optioned for Clear Channel operation for DDS
and V.54 loopbacks to take effect.
NEBE/FEBE
This test reports the quality of the network connection between
the T-1 and the switch by viewing the number of near-end block
errors (NEBE) and far-end block errors (FEBE) occurring on the
ISDN interface. An incrementing count in NEBE means the prob-
lem is in the direction of the NT-1. An incrementing count in
FEBE means the problem is in the direction of the switch.
Software Version
This test determines the software version in use on the ISU 2x64.
