Re: 15310 Inband lopback

IN-BAND loops are a series of 1 and 0's that tell a device to put a loop up or down. The typical looping devices are CSU and SMARTJACK. The loop code is sent from a test set over the actual T1 (intrusive testing).

Once the loop is seen by the test set the BER test will start.For more information read

If you access the platform via a Cisco Trasnport Controller (CTC) client (asuming your login ID has sufficient priveleges), you should be able to activate loopbacks on subscriber or trunk ports from the maintenance tab of the CTC interface.

(You will need to first put the target port into OOS-MT state from the provisioning tab.)

Hope this helps, please rate helpful posts.

The NiU functionality does not appear to be working in release 6. There should be an option to provision each DS1 for this function, so that it will recognize a loop up or down code from a T-BERD. If anyone knows any different, please advise.
