CURIOUS WHY ISDN
|
Analog modems are wonderful and complex data communications machines. For several years we, as developers, have been able (through the efforts of the DSP folk) to deliver two fold increases in speed every 12 to 18 months. Those days are coming to a close. Today there are only two major manufacturers of the core technology that is used to build modems, and together they have been able to push the maximum DCE connect (modem) speeds up to about 56K under certain conditions. This is about as fast as these devices will ever become. At the same time, ISDN technology has only recently been emerging as an acceptable alternative. Over twice as fast as a 56K modem, ISDN is a DSL (Digital Subscriber Line) technology that has been available for almost 10 years. ISDN has been long overlooked because of service deployment issues and a perceived attitude among carriers and others that ISDN is too complex for the general public. "Mr. Buffer come about, phasers on full. You may fire at will" "Aye Aye sir." If ISDN is complex, then it is only because the carriers and central office switch manufacturers have viewed ISDN with blatant disregard for the original specifications and with a total lack of understanding that has led to knot headed provisioning issues even the carriers themselves don't understand. One need only look to Germany where ISDN is both standardized and widely used to appreciate this truth. Nice shooting Mr. BUFFER <-- previous | page 1 | next --> |
