DSU or Internal Network Loopback

Testing

DSU loopback is an internal loopback that is located as closely as possible to the customer interface serving the DTE.

An active DSU loopback initiated from the network disrupts IP data going over the IMC. However, this test is not disruptive when initiated by the user (via ATI) or by the NMS.

Send V.54 Up/Down Sequences

The local DSU can send an ITU-T V.54 Up or Down sequence to request the activation or termination of a DSU (digital) loopback of a remote unit. This is the same as the DSU Loopback shown above except the test is activated remotely.

The DSU can send:

HIn-band V.54 Up (activation) code to request a Remote DSU Loopback (V.54 Loop 2) at the remote DSU, or

HIn-band V.54 Down (deactivation) code to request the termination of a Remote DSU Loopback (V.54 Loop 2) at the remote DSU.

To initiate a send sequence, select the appropriate Send command. Sending appears in the Status column followed (after 3 seconds) by Command Complete at the bottom of the screen.

511 Test Pattern for the Network

This test sends and/or monitors the 511 test pattern over the network interface.

The Monitor 511 test also provides an error counter that can be reset.

To start sending and/or monitoring, select the appropriate Start command.
