Presumably it is also equivalent to "no crc". If that's correct, then I would say you can use the same setup as you have with FT, it looks good to me.

Exact pin assignment for crossover is Pin 1 --- Pin 4 Pin 2 --- Pin 5 Pin 4 --- Pin 1 Pin 5 --- Pin 2 Not *totally sure* mind you, because I had a recent experience with a Telco where a straight cable should have worked, but didn't, so I built a crossover cable and that worked... -- Laurent Steffan Consultant VOIP Web: http://VOIP.nc _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
