Hi Robert, ISDN is very simple. In the ISDN world there is a term called TEI which is the Terminal Entity Identifier. This kind of like an IP address. Besides from the signalling there are 2 B-channels which can transport data or audio. One of my goals is to achive zero copy when moving data to/from an ISDN line and also in combination to Voice over IP. Currently data is moved through userland (Asterisk typically) which is usable in the short term, but in the long run I want this extra copying removed. The idea is that I can route [IP] packets (mbufs) through various filters in the kernel without the need for copy. --HPS _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
