The Teles card can use 2 B-Channels. I'm not certain that the existing kernel code will do channel bundling, though. Sure would be interesting to try it. And it would *really* be nice to have someone in the US test the ISDN stuff ! WRT getting 128kb/sec. I though the RBOCs in the States only support 56kb/sec. per channel ? How you going to squeeze 128kb/sec. out of that ? The D-Channel is not used for data transfer (that would be an additional 16kb/sec.). --- Gary Jennejohn (work) gjennejohn@frt.dec.com (home) Gary.Jennejohn@munich.netsurf.de (play) gj@freebsd.org
