Compression is transport independent. Compression is just a way of looking at a block of data and realizing for example that you are sending 1000 "e"s and deciding to send the number 1000 and pointers instead of the data. Any compression possible for analog modems may be done for ISDN with the basic speed ratio being 2B=128kb/s to 38.8kb/s or almost 4:1 no mattter how you cut it. ISDN also has the advantage of the B channels being used independently ( e.g one for voice and the other for 64kb/s Internet). ISDN also has a 16kb/s signaling channel which "could" also be used simultaneously. ( for a grand total of 144kb/s. ISDN is almost there in plug and play as my ISDN line came up pretty easy and has never even burped. ( my analog modem was harder to get right on my other computer - a "MAC" ( The king of plug and play) of all things). I have two crazy cordless answering machines that were hardly plug and play in my home and every time the power fails I'm reminded of this and they are on regular POTS lines just like Modems. Don't forget ISDN has most of the advantages of the analog modem in that the whole world can now switch DS0 64kb/s channels and an ISDN call can be made (or will soon) worldwide with a fixed guaranteed QOS (albeit meager) 64 kb/s. When was the last time your Internet connection ran at 64kb/s consistantly. Don't get me wrong, I like Analog modems, think ISDN has a good place and am anxiously waiting for xDSL and FTTC, a fast Internet based on ATM and lots of Internet applications which are great.
