Modems In Europe

Date: Thu, 12 Sep 91 06:15:28 PDT From: DORY%ORFE.ESNET@esnmrg.nersc.gov Subject: Responses: Use of Modems in Europe Dear Moderators I append responses by two colleagues concerning the use of modems in Europe. They are longish for a communication, so you may wish to put the body of text into an archive. Special thanks to below who responded. Bob ---------------------------------------------------------------------- Info Request: How to use Modems on European and UK Telephone Systems? ---------------------------------------------------------------------- September 3, 1991, ca 15:30 EDT. Could our European correspondents please send a bit of information on the use of modems in the European telephone systems? Do US-style modems work on continental and UK systems? Are there special adapter plugs sufficient to make an ordinary 2400 baud modem function for a call to the US? Are there TymNet- like services that will relay local calls to distant services? Are there ways to do that which are not prohibitively expensive? If none of the above, are there distributors who provide equipment that will work on a widespread basis, or is the telephone system in each country enough different that universal solutions are impractical? Are the telephone system tariffs different in each country and the laws regarding 'foreign' attachments? Which organizations are best able to sell/lease equipment, advice and legal access at a reasonable cost? Thank you in advance for your help. I will summarize and post any information received. .... .... .... .... .... .... .... .... ... .... .... .... .... ....

Date: Wed, 4 Sep 91 07:19:18 GMT Hi, You can use almost all U.S. modems in U.S.. Before buying one, make sure it supports the CCITT norms, these norms specify the transfer speeds they have. You'll have to buy one compatible with CCITT(European/International norms), in U.S., they use BELL norms but most of the modem support both. I know lots of people(including myself) who uses U.S. modems in European telephone networks. All you have to do is to find the right phone plug(easy) they use RJ11 plugs and buy a 240 to 110V A.C. Adapter. I have an ATI2400etc, with V42 and MNP error correction protocols and it works quite well here, you can buy it in US for $200. U.S. Robotics and Heys Modems also work fine... and many many of then, you only have to check if they are CCITT compatible CCITT V21 norm = 300 baud full duplex CCITT V22 norm = 1200 baud ' CCITT V22bis = 2400 baud ' CCITT V32 = 9600 baud ' CCITT V42 and/ V42bis = error correcting (also data compression) protocols.
