Terminal Operation

2048 PMU/NTU

‘AT’ modem command set. They should NOT include the
‘ATDT’ dial command prefix.

The unit attempts 3 times to connect using the primary num-
ber. If all 3 attempts fail, it will attempt 3 times to connect
using the secondary number (if it is not blank). If the sec-
ondary number fails, the unit waits 5 minutes and then
attempts to communicate with the primary number again.
When a connection is detected, the unit outputs the notifica-
tion message (as described in the ‘Element ID’ field) and
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.

Call on alarm messages are reported in the following format
in the [

DIAL

] or [

DIRECT

] modes only:

Element ID HH:MM:SS MM/DD/YY
NET Alarms: alarms
DTE Alarms: alarms

where (

alarms

) is a string consisting of some or all of the

identifiers ‘

LOS

’, ‘

OOF

’, ‘

RAS

’, ‘

AIS

’, ‘

UAS

’, ‘

ERRS

’, or

the word ‘

NONE

’. The following is an example:

Joesunit 17:24:55 08/04/93
NET Alarms: LOS AIS ERRS
DTE Alarms: LOS

The user programmable ‘Element ID’ string is transmitted
first to allow the COA function to send a message with a
specific meaning to some host (such as a log on message).

NOTE: The identifier ‘ERRS’ represents an alarm that
is caused by ES, SES, and /or BPV errors.
