I think the key is not if it can switch from IP to cellular, although that is important, the important part is does it monitor the cellular connection constantly? On my TG-1 Express, if I disconnect the antenna on the unit, within 30 seconds I get a message on the panel & an email telling me it has lost connectivity. Try that with your IPDataTel even if its in cellular-only mode. I had the IPDataTel initially and don't remember it monitoring either the IP connection or the cellular connection particularly well.Madas said:That is not the case for mine. subsequent messages seem to go directly out cellular after the one-time discovery delay. In the alarmdealer site do you see the "Connection Changed to CDMA" message?
The TG-1 does an excellent job of constantly monitoring its ability to communicate with the central office, and if there is a problem, both ends know it within 30 seconds. Does the IPDataTel?
