Carrier Access Access Navigator user manual Send DS1 Line Loopup, Example send ds1 9 csu loopup

CLI Language Reference

CLI Command List

Security: Level 2 (operator)

Syntax: send ds1 <n> csu <loopuploopdown>

Field	Description
n	DS1 number, 1 to 32, or a range of numbers such as 2-8.
loopup	Enable line loopback.
loopdown	Disable line loopback.

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.
