Alarm Configuration Options (2 of 3)

DialOut: Disab
Next Enab Disab Prev

Alarm and Trap Dial Out. Controls whether generated alarm or trap messages initiate a
call if the external communication port device connection has not already been
established. When enabled, a call is placed to the phone number contained in the alarm
directory (directory A). If the call cannot be completed and the retry option is enabled,
the alarm or trap message is held until the call is completed or the call has been retried
once. If more than one alarm message is received while waiting for a call retry, only the
highest priority alarm message received is held; all previous messages are discarded.
When the COM port is configured as the SNMP management link, up to 10 SNMP trap
messages can be queued at the interface.

Enab – Enables automatic call initiation (dial out) if an alarm or trap message needs to
be sent.

Disab – Disables automatic call initiation. Trap messages sent to the external
communication port device are queued (held) if a carrier external communication port
device connection has not been previously established. Alarm messages are not
queued.

Call Retry: Disab
Next Enab Disab Prev

Call Retry on Alarm or Trap. Determines whether a call that cannot complete (busy, no
answer, etc.) is retried. This affects calls that are initiated in attempting to send an alarm
or trap message to the carrier external communication port device. If call retry is
specified, the DSU/CSU attempts to complete the call after a configurable delay.

Enab – Enables call retry. If enabled the call is retried once per alarm or trap message.
A delay as specified by the dial-out delay time is imposed between call attempts. If an
alternate dial-out directory is specified, both the alarm directory as well as the alternate
directory are retried once.

Disab – Disables call retry. If a call setup cannot be completed it is not retried.

Dial Delay: 5
Next 1 2 3 4 5 6 7 8 9 10 Prev

Dial Out Delay Time on Alarm or Trap. Specifies the number of minutes to wait between
successive dial-out alarms or traps and between retry attempts after failed alarm
dial-outs. The factory default is 5 minutes.

AltDialDir: None
Next None 1 2 3 4 5 Prev

Alternate Dial-Out Directory for Alarm or Trap. Specifies whether a call that cannot be
completed (busy, no answer, etc.) is retried using an alternate phone number. This
affects calls that are initiated in an attempt to send an alarm or trap message to the
carrier external communication port device. The alternate phone number to try is
contained in one of the five call directories. If call retry is enabled, the initial call is
retried at the original number once before a call attempt to the alternate number is tried.
If the call is not completed at the alternate number, it is also retried once. The alternate
dial-out option applies to each alarm/trap event. Once a call for an alarm/trap message
either is completed or fails all retry attempts, the next alarm/trap attempts to establish a
call to the phone number contained in the alarm directory.

None – Specifies that alternate alarm dial-out is not performed if a call cannot be
completed to the telephone number contained in the alarm directory.

1–5 – Specifies the call directory that contains the phone number to call if a call cannot
be completed to the telephone number contained in the alarm directory.
