Set the signaling type option to match the network signaling

T391
Set the time between polls to the frame relay network.
N391
Determine how many link integrity polls occur in between full
status polls.
status polls.
N392 and N393
These parameters define the error threshold for the UNI formed
by the FSU 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.

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.
If N392=3 and N393= 4, then if three errors occur within any four
events the interface is determined inactive.
The status of the connection can be viewed in the Status menu
under Network Port Signaling State. The status will return to
active again once the threshold is no longer exceeded.

Remote FECN Notification (RFECN)
Enable/disable the FSU to issue remote FECN (forward explicit
congestion notification). This feature ensures that a frame will
be generated in the reverse direction upon receiving a frame
with the FECN bit enabled. This is a proprietary feature with
ADTRAN FSUs and can only be used with an ADTRAN FSU on
both ends of the virtual circuit.
