Isolating Problems Using Loopback Data Tests

Arrangement. If this succeeds, the problem is isolated to the network or to the remote host equipment. The user is then instructed to call a Loop-Around Data Test Arrangement at the host site (see Figure D-8). If this call succeeds, then the problem is not in the network between the switches.

The Loop-Around Data Test Arrangement does not require special switch administration over and above the normal switch administration procedure for the 8400B Plus Data Module.

If the Loop-Around Data Test Arrangement is being used to test modem pools (see Figure D-7), separate 8400B Plus Data Modules must be set up for each
