Performance/Status Menu
The Performance/Status Menu is used to monitor the functioning
and condition of the network ports. The parameters in this screen
count the various problems that occur in a given period of time.
Performance information is logged in 15-minute intervals over a
24-hour period.
To access the Performance/Status Menu from the Main Menu,
enter “P”.
Figure 3-14 Performance/Status Menu
Use the Performance/Status Menu to monitor the following:
• LOS—Loss-of-Signal. A major alarm indicating no receive
pulses at all. May be caused by disconnected or miswired
network cable. Supercedes all other alarms: ignore other
alarms and troubleshoot this condition first when LOS is Yes.
One of the three fatal T1 errors which causes a Red Alarm
condition to exist.
• LOF—Loss-of-Frame (no frame synchronization). One of the
three fatal T1 errors which causes a red alarm condition to
exist.
• AIS—Alarm Indication Signal. A received pattern of unframed
all-ones. One of the three fatal T1 errors which causes a Red
Alarm condition to exist.
• RAI—Remote Alarm Indication (Yellow Alarm) is an indication
that the remote device (which is sending a Yellow Alarm
message) is in a Red Alarm state.
• SLIP—Indicates unexpected variations in clock rate.
• CRC-6—Cyclic Redundancy Check. Method for detecting bit-
errors. Used only on ESF framed T1s.
