I can see it's technology time again - - - - time again to set a few things straight. >>28.8 modem - Based on the Lucent 56K chipset it currently runs 33.6K and is upgradeable to 56K. ITU V.34bis ITU V.42 and ITU V.42bis ITU V.17, V.29, V.27ter, V.21 TIA-602 and TIA-IS-101 (Class 8) Hayes AT compatible command set One must also remember that it's the technology behind the modem portion of the product that's the key to BT. Now as to the Eicon DIVA ISDN terminal adapter which is being tossed around - Very simply put and for concept only - ISDN generally refers to having two raw phone lines and the signalling info running straight to your home without being converted to analog at the nearest switching station. By not having the A/D & D/A conversions involved one can take advantage of the full 64 Kbps capabilities of each "pair equivalent" BUT it requires much more sophisticated equipment in the home and a very clean copper run devoid of noisy splices and the load coils the RBOCs installed ages ago to compensate for longer distance runs. Most currently available ISDN devices use one of the 64K lines for data and the other for voice, or through "bonding" they combine both to allow 128K for data. This Eicon device can also take advantage of the 16 Kbps "D" channel that is usually reserved for signalling purposes thus one could still lope along at 9.6 Kbps of data if using one of the main channels for voice and the other for FAX. It's attractive feature is that it will allow a user to "stay connected" through the 9.6K channel and automatically bring up one or both of the main 64K channels if necessary. The idea of this saving money goes with the fact that many RBOCs assess a "by the minute" charge on ISDN usage in addition to the monthly rate. It is apparently their thought that the RBOCs will allow free or low-cost usage of the D channel when the main B channels are not in use. Like I tried to tell Rod this idea isn't new by any means - it was mentioned in some trade journal early last year and I remember discussing it with Dr. Barker. It's definitely a great idea but it still requires a specialized ISDN line setup at home, at "the other end" and obviously the RBOC will need to upgrade their equipment to handle such services. Cost of ISDN lines? They vary widely by location and aren't available everywhere - matter of fact there are areas in which you may never be able to get them. Installation: expect $125 - $2000+ depending upon RBOC & work involved. Monthly: widely varies - probably averages about $50 for two B channels. Per Minute: often around 0.02/minute per B channel in use. ISP: (if applicable) probably about $100 setup and $150 per month - I think these guys are a bit high: ccr.net I might add this comment from an actual RBOC exec: "We don't really like selling ISDN service because most people that subscribe to it are doing so for an application that permanently ties up the line. The tariff structure does not allow us to make this a profitable venture even when "by the minute" charges can be applied."
