MODULES (E1/PRA-1) > ALARMS
Read security: 5
Displays the alarm type, as listed below.
LOS (Loss of Signal) No signal detected on port interface.
LOF (Loss of Framing) The receiver is unable to synchronize to the FAS framing
pattern of the received signal.
LOMF (Loss of Multi-frame) The receiver is unable to synchronize to the TS15
multi-frame pattern of the received signal.
CRC4 (Loss of CRC-4 Framing) The receiver is unable to synchronize to the CRC-4
frame pattern of the received signal.
AIS (Alarm Indication Signal) An upstream failure has been detected and all ones
are being received.
REM (Remote Frame Alarm) Loss of frame alarm being received from far end.
REMMF (Remote Multi-Frame Alarm) Loss of multi-frame alarm being received from far
end.
MODULES (E1/PRA-1) > TS0 ALARMS
Read security: 5
Displays per-TS0 alarm status. These alarms usually indicate the failure to receive the protocol that has
been configured for the TS0.
- No Alarm TS0
D D Channel Alarm (ISDN)
F Frame Alarm (packet)
T TBOP Alarm (packet)
P PPP Alarm (packet)
MODULES (E1/PRA-1) > TS0 STATUS
Read security: 5
The TS0 status indicates usage on a TS0 basis for each port. These options are read-only:
• Idle N Dedicated (nailed) TS0
– Inactive O Off hook detected
A Active call on this TS0 R Ringing detected
D Active D Channel TS0 S Signaling
M Maintenance TS0
MODULES (E1/PRA-1) > SIG STATUS
Read security: 5
Displays the state of the A/B/C/D signaling bits for the E1/PRA Network Interface Module. Dashes
indicate TS0s where signaling is not being transferred by the ATLAS 550.
