Status
Select this parameter to specify the status of a link: enabled or disabled. An enabled link transmits frames.
Normally you would want all links enabled. If a router is not working, however, the link to that router should be
disabled. All frames are then rerouted.
Type
Select this parameter to specify the type of interface in use: Asynchronous, Synchronous, X.25, or ISDN. For a
DDS or 4-wire link interface, the only link types available are Synchronous or Frame Relay.
1. When the mode is synchronous, data bits are transmitted at a fixed rate. The sender and the receiver are
synchronized.
2. When the mode is asynchronous, data units are transmitted character-by-character. The characters are
preceded by start bits and followed by stop bits. The start and stop bits provide synchronization at the receiver
side.
3. Frame Relay is a packet-switching protocol for connecting devices on a WAN.
Connection Type
Select this parameter to specify the type of connection:
• Originate only—If the link is to be used to connect to the Internet or Intranet.
• Answer only—If the link is to be used for receiving remote access connections.
• Answer&Originate—If the link is to be used for both incoming and outgoing connections (not
simultaneously).
Connection Timeout (sec)
Select this parameter to specify the connection timeout. The remote side has to answer within the time allotted
by the Connection Timeout. If within this time there is no response, you are informed that the remote side is
no longer active.
Connection timeout is
only configured when the PPP protocol is used
. The parameter consists of two parts:
• Time (1 to 255 seconds).
• Number <N> of attempts.
