Extension phones are possible, allowed for in the BRI and will certainly be a part of everyones ISDN offerings. >For no good reason, the proposed >ISDN numbering scheme is incompatible with the current numbering scheme >which makes it very likely that ISDN users will be have difficulty >setting up calls which interwork to a non-ISDN users. Totally wrong. ISDN is numbering plan independant. Perhaps you were refering to one of the numerous suggestions to numbering plan expansion, affecting *all* phone users, not just ISDN. Look at any one of the current ISDN trials. Normal numbering plans are the standard. >ISDN users will >effectively be stuck on isolated desert islands. Completely incorrect. ISDN provides a mechanism to unify and connect all networks. Also, have you ever heard of CCS7? >All the >ISDN packet switches and modules which I have seen have miserable >performance since they are designed and manufactured by people who >really only understand voice. ISDN banwidth may not be up to par with some other networks in the industry, but ISDN vendors are not blind to future directions. Have you ever heard of broadband ISDN? ISDN is still currently developing, and will certainly match network speeds of other networks, while still providing a common interface. >Worse the European PTTs are the major >driving force behind ISDN. The PTTs are not comparable to AT&T >but rather are comparable to the US Postal Service. I hope this was tongue in cheek. So what if the PTTs are goverment owned (although you obviously have not been keeping up with the current trend of European countries privatizing their PTTs). The PTTs have not had the huge profits of AT&T to build their networks with. That is why they are so much behind ISDN. It provides a method of expanding their telephone network and being standardized between countries, with an eye for easy upgrading in the future. This will in the end cut costs. >What increased bandwidth? You can already lease 56kbps lines or T1 >lines? Are you serious? Do I want to by a T-span for my house? Be real. ISDN provides decent bandwidth for a low cost. If you need much more speed, go ahead and buy your FDD network, or whatever. You'll end up having to interface with ISDN anyway because thats the way the rest of the world will be going. The whole point is ISDN is lower cost, and easily configurable, as centrex services are today. -- Paul Guthrie chinet!nsacray!paul
