PVC Tests

PVC tests can be run on a requested DLCI for a selected interface.

When PVC tests are on a multiplexed DLCI between FrameSaver devices,
they are nondisruptive to data, so user data can continue to be sent during a
test.

If the device at one end of the circuit is not a FrameSaver device, PVC tests
are on a standard DLCI and are disruptive to data. Also, the Connectivity test
would not appear.

Loopback, and send/monitor pattern tests are available for each interface on the
selected DLCI. FrameSaver devices should be at each end of the circuit. If a
PVC Loopback is started at one end of the circuit, the other end can send and
monitor pattern tests.

The example below shows a PVC Test screen for a FrameSaver unit with the
multiplexed DLCI 550 selected. If a standard DLCI was selected, (

Disruptive

rather than (

Non-Disruptive

), would be displayed after Test. Also, the

Connectivity test would not appear.

NOTE:

Errors encountered during these tests may be caused by mismatched CIRs
in the two FrameSaver units. If errors are detected, verify the CIR
configuration and retest.
