■ The Bc (Committed Burst Size) represents the maximum
amount of data that your Frame Relay service provider
agrees to transfer from a given PVC (Permanent Virtual Cir-
cuit) or DLCI (Data Link Connection Identifier). The setting
defaults to 64000, but you may modify the committed burst
size by toggling the selection in the Use Default field to No.
You can then enter a different committed burst size in the
Value field.
■ The Be (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). The setting defaults to 0,
but you may modify the excess burst size by toggling the
selection in the Use Default field to No. You can then enter a
different excess burst size in the Value field.
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 set up.

you can cancel the Frame Relay DLCI profile you have just created
by selecting CANCEL to exit the Add DLCI screen.
Default profile
Netopia can answer calls as well as initiate them over switched
circuits. To answer calls, Netopia uses a default profile. The default
profile controls how incoming calls are set up, authenticated, filtered,
and more.
For information on how to set up a default profile for a switched
circuit, see the next section.
For information on how to set up a default profile for a permanent
circuit, see
“How the default profile works for a permanent circuit,”
beginning on page 2-45 .
