ADTRAN 1200130L2, 1200130L1 user manual Set the time between polls to the frame relay network

Chapter 7. Configuring the Network Port

Signaling Type (SIGNAL)

Set the signaling type option to match the network signaling type.

T391

Set the time between polls to the frame relay network.

N391

Determine how many link integrity polls occur in between full 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.

For example:

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.

The network service provider should recommend the values entered into the T391, N391, N392, and N393 fields.
