Perhaps all digital lines support ISDN with your telco. Any modem server can be used for X2 since the modems don't care whether the incoming connection is analog or digital (i.e. the modems look like "fast modems"), but to get the most out of it you will need the new Z series serial ports (to get compression bandwidth). Unfortunately there is no FreeBSD driver available for them yet. Therefore, some legwork or brainwork will be necessary to get Z-ports to work. On the other hand, how far away are we from using Linux drivers with FreeBSD? That would be awesome! :) Another question though. Can X2 modems accept 56k connections from Rockwell and Motorola (assuming them to be the 3rd player) modems? >2) Daniel O'Callaghan's terminal server kit for FreeBSD With Radius support in the works. Daniel, in case you're listening, I'm interested in helping with this. >3) A router which I can use either a Cisco or ETinc's syncronous card > on a FreeBSD box. The ETinc card looks like the only serious high speed sync solution. Of course, you don't need this for a normal dialin terminal-server. Unless... How about a 2Mb/s connection from the telco (primary rate ISDN) with channel differentiation and modems implemented solely in software (on some custom hardware card maybe)? Might this be possible or even feasible, now or later? -- Adam David <adam@veda.is>
