Compatibilité entre SPA112 et modem USRobotics 5637

Question

Bonjour,
Je n'arrive pas à faire fonctionner correctement mon Modem USRobotics 5637 et le SPA 112, en effet ce dernier nous sert à télécharger des informations d'une centrale d'alarme intrusion. Le modem compose bien mais lors de la prise de ligne il semblerai qu'il y ait un problème de dialogue.
Cela fonctionnait correctement avec une ligne analogique et le SPA112 fonctionne correctement avec un simple téléphone.
Y a til une programmation particulière du SPA112?
Merci                  

Answer 1

Well, I arranged the environment and tried (I configured the SPA112 as suggested above). Note the SPA112 has been connected to Internet using slow 2048/256kbps ADSL line. It has 200ms RTT - it's high somewhat for Voice.
Modem speed has been limited to 9600. It connected at V.32 9600 using V.42 error correction.
The connection is not so stable, it will survive few minutes only. It is much better on 1200 speed althougt the connection is not rock stable even on this speed. But remember my ADSL is very poor.
Even with such poor line it seems to be suitable for telemetry, alarm central and simmilar applications. It's not so good for remote terminal work.
