Chapter 1 TL1 Overview

Responses

Error Response

The TimeProvider sends an Error response when a command is mis-typed, an

invalid command is issued, or some other operator error is performed. The format of

an Error response is as follows. Note that M and DENY identify the response as an

Error response:

sid date time<cr><lf>

M ctag DENY<cr><lf>

errcde<cr><lf>

;

Table 1-2 explains each field that is contained in the Error response.

Table 1-1. Normal Response Fields

Field Description

sid The unit’s Source Identifier (SID), which identifies the specific TimeProvider unit

within the synchronization network. The unit’s SID is set using the SET-SID TL1

command.

date The date of the response, in the format YY-MM-DD, where YY is the 2-digit year, MM

is the 2-digit representation of the month, and DD is the day of the month.

time The time of the response, in the format HH:MM:SS, where HH is the hour in 24-hour

format, MM is the minutes, and SS is the seconds.

ctag The correlation tag that was sent as part of the TL1 command string. If the value for

the ctag is null in the command string, the unit returns a zero ( 0 ) as the ctag in the

response.

textblk A double-quoted message containing less than 4 kBytes of information that the unit

returns in response to the command.

LG_textblk If the unit responds with a message containing more than 4 kBytes of information, the

message is divided into records of approximately 4 kBytes, each ending with

COMPLD<cr><lf>. The last record ends with <cr><lf>;.
