See Chapter 5 for definitions of local channel and uplink loopbacks in the

Setting Loopbacks in the Remote MT1000A



To set loopbacks in the remote MT1000A:

1. From the Diagnostics menu, choose Remote Device Loops.

The Remote Device Loops menu is displayed. This menu is the same as the

Local Device Loops menu (Figure 4-40).

2. From the Remote Device Loops menu, choose Loops Setting.

The Loops Setting screen (Figure 4-41) is displayed.

3. Highlight the Loop status field of the channel you want to change.

4. Enter the loopback status you want to set:

 No loop—No loopback on the channel

 LLB—Local loopback on the channel or uplink

 RLB—Remote loopback on the channel.

See Chapter 5 for definitions of local channel and uplink loopbacks in the

remote MT1000A.

The loopback test begins running immediately after a loopback has been set.

Setting the uplink local loopback in the remote MT1000A disconnects the link,

and as such, is irreversible. To remove this loopback, connect a terminal to the

remote unit or shut down the power to the remote unit. If you set the Uplink LLB

timeout on the remote MT1000A, the loopback test will stop after the specified

timeout period.

To display the current status of loops you have configured in the system:

1. Open the Diagnostics menu (Figure 4-39).

2. Choose Loop Status.

The status of all loops currently configured on the local MT1000A is

displayed.
