FarSync WAN ATM Encapsulation

For the DSL-S1 link, the point-to-point protocols are encapsulated in ATM AAL 5.  Depending on whether you are using the hdlc or Kernel ppp interface, then you can encapsulate PPP, CISCO or Frame Relay in AAL5.  It is also possible to encapsulate IP in a SNAP header, but this is only with the hdlc interface.

RFC 2364

The hdlc and pppd interfaces both support RFC 2364.  This is the default method of operation.  The ATM/AAL5 encapsulation is performed automatically when the link type is DSL-S1 and a VP/VC has been configured.  When using the hdlc interface it is also possible to encapsulate Cisco and Frame Relay protocols as well.

RFC 2684

For IP encapsulated in a SNAP header, you must use the hdlc interface.  You will need to set port parameters as follows:
