Figure 4-2 Configuring The WAN Port for PPP over HDLC
To run PPP over HDLC directly without frame relay, the Line Type field in Menu 2.1.2 - Frame Relay Setup
must be set to None. To make sure frame relay is disabled, go to menu 2 and then to Menu 2.1.2 – Frame Relay
Setup. If the Line Type field is not None, press [SPACE BAR] to change it before saving the configuration.
4.2 Configuring The WAN Port For Frame Relay
To configure the WAN port for frame relay go to Menu 2 - WAN Port Setup and change the default option (No)
in the Edit Frame Relay Setup field to Yes. Frame relay is a form of packet-switching technology that routes
frames of information from source to destination over a switched network owned by a carrier. Frames are “relayed”
through switches in the network.

4.2.1 Standards
The two main groups that create recommendations and standards in the telecommunications field are ITU - T
(International Telecommunication Union - Telecommunications Standardization Sector) and ANSI (American
National Standards Institute). Standards vary slightly for both organizations, so please select the correct standard in
the Link Management field. Your Network Service Provider (NSP) should provide you with this information.
