T391
Set the time (in seconds) between polls to the frame relay network.
Range: 5 to 30 seconds.
N391
Determine how many link integrity polls occur in between full
status polls.
Range: 1 to 255.
N392 and N393
These parameters define the error threshold for the UNI formed by
the TSU IQ+
Network
port and the frame relay switch. If the error
threshold is met, the signaling state status is changed to down,
which indicates a service-affecting condition. This condition is
cleared once N393 consecutive error-free events are received. N392
defines the number of errors required in a given event window,
while N393 defines the number of polling events in each window.
For example:
If N392=3 and N393= 4, then if three errors occur within any four
events the interface is determined inactive.
