Layer Stats and Alarm
Log
The physical layer statistics displays the T1/E1 error rate in errors per second 
for the past second. An event log (up to 5 kB) is maintained for certain 
events. The time stamp is relative to the last system reset. As new events are 
added, older events are discarded when the file size is maximized.
Events include the start and end of Telnet sessions, SNMP access with an 
invalid community name, system reset and system reset from menu command, 
and the WAN link going up or down.
