This chapter describes how to configure a SWAN interface.  The physical link should be set up as shown in
chapter 2, according to the type of modem or device at the other end of the connection and the type of SWAN
port.

STEP ONE
The first step in the SWAN interface configuration is to define its physical characteristics.  These parameters are
presented in the Physical Menu Table.

Physical Menu  CONFIG=>INTERFACE=>SWAN=>PHYSICAL

Mode

Asynchronous or Synchronous.  This parameter is determined by the mode of the
device at the other end of the connection.

Clock Source

Applies for Synchronous Mode.  Whether this interface provides clock for the device at
the other end of the cable or vice-versa. When the interface is connected to a modem,
the Clock Source is always External.

Receive Clock

Applies for Internal Clock Source.  When this interface provides clock, it can either
compare incoming messages with the clock it is generating (Internal) or with the clock
it receives from the sender along with the message (External).  External is
recommended.

Speed

Applies for Internal Clock Source.  Determines at which speed the data will be sent
across the line.

Media for SWAN
Cable

Type of cable -- RS-232, V.35 or X.21. Usually the type is cable is detected by the
router.
