The User may select VIEW or CLEAR-ALL, using the ◄ ► arrow keys, then press 

. 

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. 

Æ VIEW 

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 

 or 

 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: 

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). 

This display shows that the Switch has good monitoring I/O communications with the indicated 
modems. 

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.
