Monitor Pattern
This test monitors packets filled with a hexadecimal 55 test pattern and sequence
number over the selected interface and DLCI to another FrameSaver device.
To monitor a pattern test on a link:
Main Menu
→
Test
→
[Network PVC Tests/Data Port PVC Tests]
The current number of sequence and data errors are shown under the Result
column when the
FrameSaver unit is in sync. An
Out of Sync
message appears
when 5 frames out of 25 are missing or out of sequence.
These error counts are updated every second. If the maximum count is reached,
99999+
appears in these fields.
Connectivity
Connectivity is a proprietary method that determines whether the FrameSaver
device at the other end of the frame relay PVC is active. This test stops
automatically and can only be executed for circuit multiplexed PVCs.
To run a connectivity test on a link:
Main Menu
→
Test
→
Network PVC Tests
Selecting Connectivity sends a frame to the FrameSaver unit at the other end of
the PVC. A
RndTrip Time(ms)
message appears in the Result column when a
response is received within 5 seconds, indicating that the FrameSaver unit at the
remote end is alive (operational and connected), and the round trip (RT) time is
shown in milliseconds (ms), with a resolution of 1 ms. If a response is not received
within 5 seconds,
No Response
appears in the Result column.
