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

clearedonce 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.
