Frame Relay Protocol
The FRAME RELAY protocol is a synchronous protocol used to
concentrate two different devices into a common frame relay link to
the network. While configured for FRAME RELAY 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 FRAME RELAY protocol is
selected.
Physical Layer Options (PHYS LYR OPTS)
Interface Type (INTERFACE)
Select the connector type for the DTE interface. The choices are
EIA-232 and V.35. See Table A-4 in the appendix Pinouts for the
connector pin assignments.
Bit Rate
Select the operating speed of the DTE interface.
The bit rate selections vary depending on the speed selections made for the
Network port. Also, for rates higher than 56/64 kbps, the External DCE
card is required.
