When the Dual Trunk E1 Router detects an alarm condition, the unit reports the condition to the
terminal.
Depending on your network management environment, the unit may also send alarm messages or
SNMP trap messages.
Set alarm conditions in Menu-8A, Alarm Configuration.
The Dual Trunk E1 Router reports alarm conditions to the device connected to its COMM Port
(such as a terminal or modem)
SNMP traps are sent as configured in Menu-0B, SNMP Configuration; otherwise, the connection
indicated in Menu-8C identifies from where the alarms are reported.
If a modem is connected, the unit causes the modem to dial out (if in Menu 8C, Connection is set to
Modem; valid telephone numbers are set in Phone Number 1 or Phone Number 2; in Menu-8A.
Ethernet Signal Loss Alarm
is Enabled and Block all Alarms is set to No).
How Alarm Reports Are Displayed
Alarms are displayed on a terminal at the bottom of the screen when the terminal is connected to the
COMM Port and you are logged on:
Example—Ethernet Signal Loss Alarm will be given at the bottom of the screen, as follows:
??? ID: Oahu Data1 Carrier Loss Start: 07:17:37 Feb.22, 1997--
The alarm includes the unit ID, type of alarm, start or end of alarm condition, date, and time. The
alarm information remains on the screen either until a new alarm occurs or until you select a new
screen.
When no alarm is present, a dotted line (similar in appearance to the one below) is shown:
---------------------------------------------
When you are not logged on, the alarm appears as a single line showing the unit ID, type of alarm,
start or end of alarm, and the time stamp, if IP is disabled.
In SNMP mode, the system sends the alarm as an SNMP trap to the SNMP manager which displays
it on the SNMP console.
NOTE: If IP is enabled, only SNMP traps are sent. Alarms will not be
displayed on the terminal.
