In an ACS-166 dual terminal multiplexer, if an alert or alarm condition occurs on either terminal,
the shelf goes into its corresponding alarm state. It is therefore possible for the shelf to register
an alarm while one of its two terminals is still operating normally. Table 5-7 defines all the alert
and alarm messages that can appear in the CM-5RB response to a STATUS? command.
Table 5-7. Alert and Alarm Messages Responding To STATUS? Command
Message Meaning
REDUNDANT POWER SUPPLY
FAILURE One of the two power supplies on the main shelf or (if so equipped) one
of the two power supplies on the expansion shelf has failed.
ALARM AT CNN The channel module with card address nn ( nn = 01 to 36) is in an alarm
state. This message appears when there is an alarm at one (and only
one) channel module.
Reported by a TERM or DI-A module only.
ALARM AT N CHANNEL CARDS There are n channel modules in an alarm state. This message appears
when there are at least two channel modules in an alarm state. Issue
STATUS? commands to specific channel modules to determine exactly
which modules are in trouble (Section 5.2.3.5 – Channel Module Status ).
Reported by a TERM or DI-A module only.
ALERT AT CNN The channel module with card address nn ( nn = 01 to 36) is in an alert
state. This message appears when there is an alert at one (and only one)
channel module.
Reported by a TERM or DI-A module only.
ALERT AT N CHANNEL CARDS There are n channel modules in an alert state. This message appears
when there are at least two channel modules in an alert state. Issue
STATUS? commands to specific channel modules to determine exactly
which modules are in trouble (Section 5.2.3.5 –
Channel Module Status ).
Reported by a TERM or DI-A module only.
TRANSMITTER USING FTIME = INT
(fallback timing) The T1 transmitter is using its fallback (internal) timing mode.
TRANSMITTER CLOCK FREE
RUNNING
The T1 transmitter has dropped out of its primary timing mode but for
some reason cannot operate in its fallback timing mode.
NO OUTPUT FROM TRANSMITTER The T1 transmitter is not generating an output signal.
RECEIVE SIGNAL LOSS No signal is detected at the T1 input.
EXCESS JITTER Excess jitter is detected at the T1 input.
RECEIVER OUT OF FRAME The T1 receiver has lost frame synchronization.
OTHER SIDE (DI-B) IS OUT OF
FRAME The T1 receiver in the DI-B module has lost frame synchronization.
Reported by a DI-A module only.
OTHER SIDE (DI-A) IS OUT OF
FRAME The T1 receiver in the DI-A module has lost frame synchronization.
Reported by a DI-B module only.
RECEIVING ALL ONES A framed or unframed all-ones signal is detected at the T1 input.
RECEIVING YELLOW ALARM A Yellow Alarm signal is detected at the T1 input.
PAYLD-LB = ON (payload loopback
on)
Using loop timing for payload
loopback
The Payload Loopback is active.
LINE-LB = ON (line loopback on) The T1 Line Loopback is active.
EQPT-LB = ON (equipment loopback
on) The T1 Equipment Loopback is active.
CONFLICT AT TIME SLOT n There are two or more channel modules assigned to time slot n. The
time slots are 1-24.
RECEIVING 10^-3 BIT ERROR RATE There is a bit error rate alarm (Section 6.3.5.3 - Studio-Transmitter Link
(STL) Alarms ).
