Yes, I am aware that the Ascend Pipeline 50 has two 64kb channels which I use all the time to hold audio/video conferencing from my FreeBSD box. The fact that the Ascend Pipeline 50 is unsuitable for handling multiple ISDN lines is more of a reason to support ISDN cards. My original point is that is physically impossible for an Ascend Pipeline 50 to handle 256kb because it does not have two ISDN interfaces . If we wanted to support two ascend pipeline 50 the easies way would probably be to have two ethernet segments each connected to a different Ascend Pipeline 50. If memory does not failed me ISO TP4 supported bonding right on the stack -- so if anyone is interested on this area I suggest this may be a good place to start. ISO TP4 --- I forgot the official ISO name however TP4 is sort of like tcp/ip however it has more control features. Well, I better leave all this alone cause I may fall back to my old networking ways 8) Amancio >>> James Robertson said: > > > On Wed, 17 Jan 1996, Amancio Hasty Jr. wrote: > > > Well, my Ascend Pipeline 50 has just one isdn interface so two > > ISDN lines is out of the question. > A single ISDN line has two 64K data channels, each with it's own phone > number (SPID).
