If Congestion Management is enabled, this option causes the Netopia Router to use in-bound FECNs
(Forward Explicit Congestion Notification). This feature is designed to notify you that congestion avoidance
procedures should be initiated where applicable for traffic in the same direction as the received frame. It
indicates that the frame in question, has encountered congested resources.
Note: The Congestion Management Enabled field will only appear if Standard or Buffered is selected as
the option from the Tx Injection Management field.

Frame Relay DLCI configuration
If you selected None as your LMI Type then you will need to manually configure your DLCIs.
A Frame Relay DLCI is a set of parameters that tells the Netopia Router how to initially connect to a remote
destination.
The Netopia Router supports up to 16 different Frame Relay DLCI profiles.
Each Frame Relay DLCI configuration you set up allows the Netopia Router to connect your network to another
network that uses IP or IPX over Frame Relay.
