Connectivity; Test Call - Paradyne iMarc SLV Operation Manual

5. Troubleshooting

Connectivity

Connectivity is a proprietary method that determines whether the iMarc 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:
Selecting Connectivity sends a frame to the iMarc 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 iMarc 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.

Test Call

Test Call tests the device's ability to place a call. It allows an alternate means of
controlling the activation or deactivation of an ISDN link. This test only appears for
an iMarc device with a DBM that is configured to originate backup calls (typically,
the remote site) and has its ISDN Link Status option set to Auto.
To place a test call:
When a test call is started, Active appears in the Status column. While the call is
Active, the status of the call connection and the link appears in the Results
column.

A Frame Relay Link Up message indicates that the required calls have
been made and the link is successfully passing LMI data.
A Frame Relay Link Suboptimal message indicates that at least one
call has been made on the link, the link is successfully passing LMI data, but
the Maximum Link Rate configured in the ISDN Link Profile has not been
achieved for the link.
A Frame Relay Link Down message indicates that the call attempts were
not successful.
NOTE:
Primary network data is not affected by a test call. If there is a network failure
while a test call is active, the test call is terminated and the call is automatically
converted to a backup call.
