E1-a 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=NONE Output framing is NONE (if an analog signal). (If
ALMOUT is SQUELCH, the signal will turn off
during holdover alarm. No other ALMOUT
option affects output during alarm.)
ALMOUT=b b = AIS Output during holdover alarm is AIS
b =
SQUELCH No output during holdover alarm
b = SSM Output is “SSUT” quality level message during
holdover alarm (SSM requires output framing of
CAS4 or CCS4)
OPT-a
(Additional
eight E1
outputs for
990-
72020-02
systems
only) ALMOUT=b b = AIS Output during holdover alarm is AIS
b =
SQUELCH No output during holdover alarm
b = SSM Outputs is “SSUT” quality level message during
holdover alarm (SSM requires CAS4 or CCS4
output 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 = NONE Output framing is NONE (if an analog signal) (If

option affects output during alarm.)
OPT-a
(ESCIU for
990-
72020-04
systems
only) 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
