MONITOR=b b = ALW Monitor is used for alarm purposes
b = INH Monitor is not used (INH) for alarm
purposes
ALMOUT=b b = AIS When the ESCIU detects an LOS on one
of its input spans, AIS is output to the NE
(the E1 alignment sequence is blocked)
b =
PASSTHRU
When the ESCIU detects an LOS on one
of its input spans, the E1 alignment
sequence is passed through to the NE
with the original input alarm

ALMOUT=b b = AIS Output is AIS during alarm
b = SQUELCH Output is squelched during alarm
b = SSM Outputs are at “STU” quality level for ESF
framing and at “SSUT” quality level for
CAS4 and CCS4 framing during holdover
alarm (SSM requires CAS4, CCS4, or
ESF framing)
FRAMING=b b = CAS Output framing is CAS
b = CAS4 Output framing is CAS4
b = CCS Output framing is CCS
b = CCS4 Output framing is CCS4
b = D4 Output framing is D4
b = ESF Output framing is ESF
b = NONE Output framing is NONE (analog) (If
ALMOUT is SQUELCH, the signal turns
off during holdover alarm. Any other
ALMOUT option does not affect output
during alarm.)
