Serial V.35 card

[Pedro Zorzenon Neto <pzn@terra.com.br>]

Hi folks,

   I have a NEC Pasolink network equipment and would like to connect it
with a Debian computer to use it as a router, instead of buying a Cisco
router.

   I have no previous experience about it. I know the Pasolink has a
V.35 syncronous serial port.

   Which hardware do I need to connect it to the computer?
   Does potato has the kernel modules to work with this hardware?
   Which protocol does the V.35 uses to encapsulate IP?

     Thanks in advance,
     Pedro
