STEP TWO
The second step is to choose a data-link protocol in the Encapsulation menu. There are many encapsulation
options on this interface.
For synchronous communication:
• Frame Relay: the Frame Relay Protocol is based on frame switching and constructs a permanent virtual
circuit (PVC) between two or more points.
• X.25: The X.25 Protocol is generally used to connect to a public network. The router can act either as a DTE
or a DCE.
• HDLC: A proprietary alternative to PPP.
For synchronous or asynchronous communication:
• PPP: The PPP (Point-to-Point) protocol is used for leased, dial-up, and ISDN lines. Multilink PPP is also
provided.
Information on how to determine the values of the parameters for each data-link protocol is provided in chapter 8.
STEP THREE
The third step is to set the Network Protocol parameters. Information for this step is provided in chapter 7.
