Avocent Access Router Cyclades-PR2000 ユーザーズマニュアル

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 and dial-up 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.
