Wan Port Setup; Frame Relay - Multitech MultiFRAD FR221 User Manual

Chapter 4 - MultiFRAD Software

WAN Port Setup

The WAN Port Setup dialog box selects whether the DSU port is enabled or not and controls how this
port is configured (i.e., for frame relay or for point-to-point operation). For Frame Relay operation, you
can ignore everything in the Mode and Connection Method groups on this dialog box. For point-to-
point operation, the FR221/V2 voice/fax channels are not operational.
Note: Refer to Appendix D if in the future your WAN network is upgraded to T1/E1 and you then want
to disable the MultiFRAD's internal DSU and use the back panel Trunk connection to obtain data
rates of up to 2.048 Mbps.

Frame Relay

When the WAN port is configured for frame relay (the default), then the mode is Synchronous and
DSU Clocking is set for external (DDS) clocking from the network. For Frame Relay operation, the
DSU encapsulates data for transmission over a frame relay network. Additional frame relay
configuration is necessary by clicking Frame Relay on the MultiFRAD main menu.
Note: The FR221 and FR221/V2 MultiFRADs use the DSU functions (Loop Back and Clocking) on
this screen.
