Carrier Access Access Navigator user manual Send DS1 NIU Loopup, Example send ds1 9 network loopup

		CLI Language Reference
		CLI Command List
Syntax: send ds1 <n> network <loopuploopdown>
	Field	Description
	n	DS1 number, 1 to 32, or a range of numbers such as 2-8.
	loopup	Enable network loopback.
	loopdown	Disable network loopback.

Example: send ds1 9 network 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 network 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 NIU 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 or D4 (SF) framing. This command also works with SLC-96/TR-08 framing for Shelves B, C, D. (For Shelf A, use the command Send DS1 Line Loopup on page 18-63.)

Purpose: Sends an in-band(bit pattern) line loopup or loopdown code over the Access Navigator DS1. The NIU loopup is used with other commands and test equipment to verify that the DS1 signal is reaching a far-end Network Interface Unit (NIU), such as a “Smart Jack.”
