LOSE TxFRM: Loss of Tx frame occurs in Drop & Insert operation,
when the incoming T1 or E1 frame cannot be found by the modem.
BER >10E-3: This error rate monitor is enabled for IBS and IDR
framing.
LOSE TxMUL: Loss of Tx multiframe occurs in E1-CAS D&I operation,
when the multiframe marker for CAS signaling data cannot be found.
Tx Sig AIS: An AIS condition in the signaling positions of an incoming
E1-CAS frame is monitored.
TX TERR RM indicates the presence of the Tx terrestrial remote alarm
on the incoming T1 or E1 frame.
IBS RX REM indicates the presence of the IBS satellite remote alarm
(backward alarm) on the incoming IBS frame from the transmit side of
the link.
IDR RX BW1-4: Multi-destinational backward alarms are the
corresponding satellite alarms used by the IDR frame structure.
IDR TX BW1-4: Backward alarms 1-4 indicate that the hardware inputs
available on the back panel of the modem have triggered, resulting in
the corresponding Tx backward alarm being generated by the modem’s
IDR framer.

An example of a Stored Events screen is shown. Use the [↑] [↓] arrow keys to select
Clear All: YES or NO, then press ENTER.
Use the [←][→] arrow keys to select the ‘#’ character on the bottom line to view the log
entries. Scroll backwards or forwards through the entries in the event log, using the [↑]
[↓] arrow keys. Pressing ENTER or CLEAR will take the user back to the previous
menu. The event log can store up to 199 events. When a fault condition occurs, it is timestamped and put into the log. Similarly, when the fault condition clears, this is also
recorded.
If the user selects CLEAR ALL, the event log is cleared, and the user is taken directly
back to the previous menu. However, if there are faults present on the unit at this time,
they will be re-time-stamped, and new log entries will be generated.
Note that in accordance with international convention, the date is shown in DAYMONTH-YEAR format.
