E1-a
ALMOUT=b
b = AIS
Output is AIS during alarm
b =
SQUELCH
Output is squelched during alarm
b = SSM
Outputs are at “SSUT” quality level 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 (analog) (If
ALMOUT is SQUELCH, then signal turns off
during Holdover alarm. Any other ALMOUT
option does not affect output during alarm)
OPT-a
(Additional
E1 outputs
on 990-
72020-02
systems
only)
ALMOUT=b
b = AIS
Output is AIS during alarm
b =
SQUELCH
Output is squelched during alarm
b = SSM
Outputs are at “SSUT” quality level 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 (analog) (If
ALMOUT is SQUELCH, then signal turns off
during Holdover alarm. Any other ALMOUT
option does not affect output during alarm)
OPT-a
(990-72020-
04 systems
only)
ALMOUT=b
b = AIS
When the ESCIU detects an LOS on an input
span, AIS is output to the NE (the E1 option
does not affect output during alarm)
b =
PASSTHRU
When the ESCIU detects an LOS on an input
span, the E1 alignment sequence is passed
through to the NE with the original input alarm
