Frame Relay Protocol

The

RAME

ELAY

protocol

is a synchronous protocol used to

concentrate two different devices into a common frame relay link to

the network. While configured for

RAME

ELAY

protocol, the

Express 5210 accepts frame relay frames from a router or a FRAD

and routes to/from the network port based on the DLCI address.

The address can be modified or preserved from the DTE and

network side based on the frame relay address table. FECN, BECN,

DE, and C/R states are not changed as frames are transferred

between the

DTE and the Telco ports. The menu tree in Figure 7-4

shows the choices available when the

RAME

ELAY

protocol is

selected.
