- Modems seem to be approved indidually in each country, which is
- why there is a US, a UK, a German version etc. If you use a modem
- in a different country it won't be an approved model.
-
- BUT it will probably work ok, as the modulation standards for the
- higher speeds are universal, and international travellers carry
- modems around with them, plus in many cases an international travel
- kit, containing a range of phone jack adapters. To avoid the
- voltage problem, many use modems that can use either local mains
- voltage when it is suitable, and a 9V battery in countries where
- it isn't, with a growing number using PCMCIA modems.
-
- The chief differences are minor, mains voltage and frequency
- (some US modems with underspecified transformers will run off
- an auto-transformer to get the voltage right, but cook from the
- 50 Hz as opposed to the 60 Hz), phone cord, number of redials
- permitted, call progress tone recognition, guard tones, permitted
- range of signal levels etc etc. Mostly you can work around these.
-
- I would hesitate in flash upgrading a modem with a different
- country to the one the modem was sold for, flash upgrade. Which
- means, you might at some time have problems supporting the modem,
- or getting USRobotics in Europe to support a US market modem.
-
- As a University students from around the world arrive with their
- modems, laptops (and viruses). We can't adapt a non-approved
- modem for them, but can tell them about the differences, from
- which they seem to deduce how to get the modems to work. It seems
- that 95% or so are successful. Of course the may also get help
- from other students.
