DialOut: Disab
Next Enab Disab Prev
Alarm and Trap Dial Out. Controls whether generated alarm or trap messages initiate a
call if the integral modem connection or carrier 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
has been retried unsuccessfully 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 modem 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 mes sage n eeds to be
sent.
Disab – Disables automatic call initiation. Trap messages sent to the modem port or
carrier external communication port device are queued (held) if an integral modem
connection or carrier external communication port device connection has not been
previously established. Alarm messages are not queued.
NOTE: For carrier-mounted DSU/CSUs, this configur ation option is only available if the
communication port is enabled for an external device.
Call Retry: Disab
Next Enab Disab Prev
Call Retry on Alarm or Trap. Determines whether a call that cannot be completed (busy,
no answer, etc.) is retried. This affects calls that are initiated in attempting to send an
alarm or trap message to the modem port or carrier external communication p ort 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 pe r 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.
NOTE: For carrier-mounted DSU/CSUs, this configur ation option is only available if the
communication port is enabled for an external device.
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 before a retry attempt after failed alarm dial-outs.
The factory default is 5 minutes.
NOTE: For carrier-mounted DSU/CSUs, this configur ation option is only available if the
communication port is enabled for an external device.
