PVC Tests
PVC tests can be run on a requested DLCI for a selected interface.
T 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.
T 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 ISDN
backup capability, 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.
PVC Tests Screen Example
If the unit does not have the ISDN DBM feature, or if the ISDN Link Profile’s Link
Status is disabled,
Test Call does not appear. An Outbound Phone Number
must be configured for Test Call to 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.
