Access Navigator - Release 1.8
CLI Language Reference
CLI Command List
Purpose:
Sends an out-of-band (FDL) line loopup or loopdown code over the Access Navigator
DS1. It is used with other commands and test equipment to verify that the DS1 signal
is reaching far-end CSU equipment, such as the Access Bank.
Line loopups can be used with either unframed (line) or framed (payload) patterns and
test commands, including
Send DS1 Line <pattern>
,
Send DS1 Line <pattern> Test
,
Send DS1 Payload <pattern>
, and
Send DS1 Payload <pattern> Test
.
When the operator sends a
line
loopup
command, the Access Navigator transmits
a T1.403 defined out-of-band line loopback activate code over the FDL channel of the
drop DS1 to the CSU. After the required 5-second integration time, the CSU should
perform a line loopback, which loops the received DS1 frame back to the DS1 transmit
output (see Figure 18-4).
When testing is complete, send a
line
loopdown
command.
NOTE:
This command will send one of the following T1.403 defined FDL
code words, repeated for 5 seconds.
Line loopback activate:
00001110 11111111
Line loopback deactivate:
00111000 11111111
