Terminal Operation

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 <CR> <LF>
NET Alarms: alarms <CR> <LF>
DTE Alarms: alarms <CR> <LF>

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 2A 2B 3A 3B

The user programmable ‘

Element

ID

’ string is transmit-

ted 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.

Telnet Option

Telnet expands the Ethernet or Token Ring capabilities of
the PRISM unit. With the telnet feature installed, any telnet
compatible station emulating an ANSI VT100 terminal can
communicate with the PRISM unit. Fractional loopback and
BERT can be initiated and monitored from any telnet com-
patible device in the wide area network (WAN). Note that
only a single telnet session is supported at any one time.

The user must be familiar with telnet operation to begin
communication with the unit (refer to the telnet documenta-
tion) The telnet interface provides security through pass-
word layers identical to those described in this chapter for
the terminal interface. Once communication is established,
all telnet screens are identical to those described for the ter-
minal interface.
