What we have been trying to develop here is a sort of a huge ISDN Terminal Adapter in Software - which means: [PRI Line] <---> [Sync2Async] <---> [PC Gateway] What we plan on doing is grab all 30 B channels from the PRI line, convert the Sync PPP used on ISDN lines to Async PPP, and use a 36-Port Serial Board inside the PC to run Multilink PPP. (Again, like one huge Terminal Adapter) We already have the hardware to terminate the PRI line and give us 30 B-channels, with PPP on top. What were missing is how to actually "chew up" and spit out the synchronous PPP/HDLC frames into our serial ports inside the PC. Any ideas...? Thanks in advance !
