2. Plug the H600-383 cable from the MM710 into the female connector on the loopback jack.

3. Plug the male connector on the loopback jack cable into the network interface point.

Note:

Do not remove the loopback jack after installation. This is not a test tool and 
should always be available to remotely test a DS1 span.

Use one of the following installation methods:

●

Install the loopback jack at the point where the cabling from the ICSU plugs into the dumb 
block.

●

If there is more than one dumb block, choose the one that is closest to the Interface 
Termination feed or the fiber MUX, to provide maximum coverage for loopback jack tests.
