Access Navigator - Release 1.8 August 2003 18-63
CLI Language Reference
CLI Command List
Security: Level 2 (operator)
Syntax: send ds1 <n> csu <loopup|loopdown>
Example: send ds1 9 csu loopup
Message: Loopup signal sent to remote.
Waiting for confirmation.....loopup confirmed.
The above message indicates that the loopup code was sent and that the Access
Navigator confirms that the far-end is in loopback. If the message ends with “unable to
confirm loopup” there may be a line or equipment problem in the DS1 loop. When
testing is finished, always use the loopdown command to return the far-end equipment
to normal operation.
Example: send ds1 9 csu loopdown
Message: Loopdown signal sent to remote.
Waiting for confirmation.....loopdown confirmed.
The above message indicates that the loopdown code was sent and that the Access
Navigator confirms that no loopback signal is being received from the far-end. If the
message ends with “loopup still present” the far-end equipment is still in loopback
mode.
If the code can not be sent, the CLI will display an error message, as in the following
example.
Message: *- unable to set up ds1 because ds1 is reporting an alarm
condition.
Send DS1 Line Loopup
NOTE:
The DS1 must be set Out of Service, using the set ds1 <n> down
command, before you can use loopbacks or test patterns.
NOTE: For normal operation, the loopback must be disabled (loopdown).
NOTE: This command works with ESF framing and T1.403 FDL, or with
SLC-96/TR-08 framing for Shelf A. For Shelves B, C, D, use the command
Send DS1 CSU Loopup on page 18-62. An Access Bank II using Carrier
Access FDL protocol will ignore this command.
