Payload Loopback

The Payload Loopback (PLB) loops the information received on the Network or

DSX-1 interface back to the network after it has passed through the receive and

transmit framing section of the device. Use PLB for determining whether the

problem is with the T1 facility or in the circuitry of the remote device.

The following tests cannot be running when a payload loopback test is initiated:

Line Loopback or Repeater Loopback on the same Network or DSX-1

interface

Send Pattern Test on the same Network or DSX-1 interface or any data port

assigned to this interface

Send Remote Line Loopback on the same Network or DSX-1 interface

Send V.54 or Send FT1 Loopback on any data port assigned to this Network

or DSX-1 interface

Data Channel Loopback on any data port assigned to the same Network or

DSX-1 interface

CAUTION:

Payload Loopback may affect the operation of the FDL, DDL, or EDL.

Any IP data being sent while this test is active will be disrupted. Also,

any performance statistics being sent over the EDL will be disrupted.
