TL1 Command Interface
The format for a complied (COMPLD) output response message is:
<cr lf lf>
^^^sid^date^time <cr lf>
M^^ctag^COMPLD <cr lf>
[^^^”response message” <cr lf>]
[...]
;
where:
sid (Source Identifier) is the returned ID, and is the same as the tid in the input
command message to which the IP acknowledgment is responding
date is the current year, month, and day in the SSU-2000 in the format:
YY-MM-DD
time is the current hours, minutes, and seconds timestamp information in the
SSU-2000 in the 24-hour format: HH-MM-SS
ctag (Correlation Tag) field is a six-digit alpha-numeric message identifier code
that is received with the command and returned in the response, for correlation of
message and response within the operating system
COMPLD is the complied message
“response message” is the response message. The response message line for
complied messages always begins with 3 spaces (^^^) followed by the response
message enclosed in quotation marks, and terminated by <cr lf>. Multiple lines of
response messages are allowed. Each command response is terminated by a
semicolon following the last <cr lf>.
DENY Output Response Message Conventions – The DENY response contains
a four-character error code (ercd) that describes the reason for the denied
response. For example, the error code ICNV indicates Input Command Not Valid.
The error codes are listed in Table B-3.
The SSU-2000 sends the DENY response when:
the cmd is not valid
the aid is not valid
the ctag is not valid, indicated by a response containing the ctag set to a single
zero character (0)
the unit is unable to comply with the request for the reason indicated by the ercd
The format for a denied (DENY) output response message is:
<cr lf lf>
^^^sid^date^time <cr lf>
M^^ctag^DENY <cr lf>
^^^ercd <cr lf>
