Chapter 2 TL1 Reference
Retrieve TDEV Data
124 SSU-2000 Technical Reference 12713020-003-2 Revision F.01 – January 2007
Retrieve TDEV Data
This command returns TDEV data for a port on a DS1, E1, or Sine Input module.
This command requires an aid to identify the input port to report data from. The ctag
and a null field are followed by optional parameters which contain a clock identifier
clksrc [CLK-A | CLK-B] and the start and stop times for the measurement. If no clock
source is specified, the current output clock is used.
Syntax
RTRV-DATA-TDEV:[tid]:aid:ctag[::[clksrc][,start][,stop]];
Response Format
The response is the complied message followed by the
requested data.
Only the
values available in the interval between the start and stop times is output.
The
format for each response message line is
:
^^^"aid:ocrdat,ocrtm,TDEV,clksrc,tmper,monval"<cr lf>
where:
aid = port access identifier
ocrdat and ocrtm = the beginning date and time the data was collected
clksrc = clock used for the measurements
tmper = time period for the measurement data, in seconds
monval = data value for the time period, in nanoseconds. The maximum tmper
values for TDEV are 0.1, 0.3, 0.6, 1.0, 3.0, 6.0, 10.0, 30.0, 60.0, 100.0, 300.0,
600.0, 1000.0, 3000.0, 6000.0, and 10 000.0
Only the values available in the interval between the start and stop times are output.
Parameter Value Description
[aid] S1Ay-z Retrieves the current TDEV data from the specified Input
port.
[clksrc] CLK-A |
CLK-B
Specifies which clock supplies the TDEV data. If clksrc
is not specified, the current output clock is used.
[start] {MM-DD},
{HH:MM}
Specifies the start date and time for data. If the date is null
but followed by a time, the command defaults to the current
date. If the start time is null, but preceded by a date, the
command defaults to the current time. If the start date and
time are null, the command defaults to the start of the data.
The comma must be present to indicate a null start time.
[stop] {MM-DD},
{HH:MM}
Specifies the stop date and time for data. If the date is null
but followed by a time, the command defaults to the current
date. If the stop time is null but preceded by a date, the
command defaults to the current time. If the stop date and
time is null, the command defaults to the end of the data.
