PSTN and GSM alarm system
What is PSTN?
Telemetry and ordinary phone lines.
Public switched telephone network. Basically the normal phone network, or land line.
PSTN is a wired connection which on industrial premises is usually routed through the switchboard. Past experience shows that it can be very difficult to get a PSTN connection in the depths of the manufacturing plant. These connections are also unreliable with people unplugging cables and reassigning lines within the switchboard. Remote telemetry units use the telephone line very little compared so when the administrator analyses phone line use sees little or sometimes no activity and assumes it is no longer in use and cancels it.
For these reasons we recommend wireless data acquisition solutions, therefore ensuring the long term reliability of your remote monitoring system.
