Parameters

The following fields pertain to the call on alarm (COA) parameters.

Alarm Notification

This field controls remote alarm reporting. The choices are as follows.

OFF.

Disables alarm reporting.

DIRECT.

Sends reports to a printer or terminal connected directly to the

supervisory port.

DIAL.

Sends reports through an attached AT-command-set-compatible modem

connected to the SUPV serial port, which must dial out to a remote modem. The
message format is described in the Element ID field.

DIAL NMS.

Sends reports through a modem to an EM8000 Network Manager or

8100A Site Controller workstation.

Primary Phone#, Secondary Phone#

These fields are ASCII strings for the primary and secondary call on alarm phone
numbers used in the DIAL and DIAL NMS modes. The strings must be compatible
with the standard AT modem command set. They should not include the ATDT
dial command prefix.

The unit make three attempts to connect using the primary number. If all three
attempts fail, it make three attempts to connect using the secondary number (if it is
not blank). If the secondary number fails, the unit waits five minutes and then
attempts to communicate with the primary number again. When a connection is
detected, the unit outputs the notification message (as described in the Element ID
field) then disconnects.

Element ID

This field allows the entry of an ASCII string (29 characters in length) which
identifies the unit to the device receiving the alarm notification messages.

DIRECT modes only.
