The Default Be (Be also referred to as Excess Burst Size) 
represents the maximum amount of data that your Frame 
Relay service provider will attempt to deliver to a given PVC 
(Permanent Virtual Circuit) or DLCI (Data Link Connection 
Identifier). This setting defaults to 0, but you may change the 
capacity rate if this setting needs to be modified. 

See Appendix B, “Understanding Frame Relay” in the 

Getting 

Started Guide for information on the these parameters.

Note: Some Frame Relay service providers allow for 
over-subscription of the DLCIs, which occurs when the total 
number of CIRs for all PVCs exceeds the line rate setup.

Select Congestion Management Enabled and toggle to Yes or No 
depending on whether you use this selection. Press Return.

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.

Select Maximum Frame Size and press Return. The default is 
automatically set to a value suitable for encapsulating a full 
ethernet packet’s transmission load, however you may change 
the Maximum Frame Size to suit your networks transmission load. 
Press Return.

You are now done configuring the Frame Relay Configuration screen. 
Press the Escape key to return to the WAN Setup screen. If you need 
to configure your DLCIs, go to the section below. Otherwise, go to 
“Connection Profiles for ISDN and Leased lines” on 

 to set 

up your connection profile for a remote site.

If you selected None as your LMI Type then you will need to manually 
configure your DLCIs.
