Basically the normal phone network, or land line. PSTN is a 'hard wired' connection typically between two devices. Within Telemetry these devices would tend to be a masterstation/computer and a number of outstation/RTUs. This method of communication between the remote device and the host is still the most common within the telemetry outstation market. This was due to its general ease of connection, cost and reliability. However, this is starting to reduce with alternatives such as GSM and GPRS communication starting to compete in the key areas such as ease of connection, cost and reliability.
