7.6.3 MONITOR: STORED-EVENTS
STORED EVENTS: VIEW
CLEAR-ALL (PRESS ENTER)
The User may select VIEW or CLEAR-ALL, using the ◄ ► arrow keys, then press [ENT] .
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, new log entries
will be generated for those faults.
Note that the date is shown in DAY/MONTH/YEAR format, in accordance with international
convention.
7.6.3.1 MONITOR: STORED-EVENTS Æ VIEW
LOG23: 26/01/00 10:37:32
FT-06 RX ALARM (UP/DN)
The User may scroll backwards or forwards through the entries in the event log, using the ▲ ▼ arrow
keys. The event log can store up to 98 events. Press
[ENT] or [CLR] to return to the previous menu.
When a fault (FT) condition occurs, it is time-stamped and put into the log. Similarly, when the
fault condition clears (OK), this is also recorded, as shown below:
LOG24: 26/01/04 10:37:35
OK-06 RX ALARM (UP/DN)
Next to the FT/OK indicator is a number/code for the faulted unit: the TM slot number (1 through
10), RM (for Redundant Modem) or SW (for the Switch).
7.6.4 MONITOR: COMMS (Communications State)
GOOD COMMS WITH MODEMS:
1 2 3 - 5 - 7 8 – 10
This display shows that the Switch has good monitoring I/O communications with the indicated
modems.
7.6.5 MONITOR: IO
<0100/LRS?
>0100/LRS=1
This display shows actual communication strings between the Switch and the modems:
Upper line = Switch controller’s outbound messages
Lower line = Modem’s inbound responses
When in this mode, the communication is slowed down to enable viewing of messages. Because
of this, it should only be used for troubleshooting purposes.
