Ok, heres a url showing it to be full duplex, it took awhile to find. http://www.cisco.com/univercd/cc/td/doc/pcat/150.htm Brian Sonic Whalen Success = Preparation + Opportunity On Wed, 13 Jun 2001, [EMAIL PROTECTED] wrote: On Wed, 13 Jun 2001, Swart Douwe wrote: On a 64K dedicated ISDN line, copying a file across, we receive a throughput of around 10kbps.

Would frame-relay also be full-duplex then?? Thanks..
