PSTN Communication Devices for the M²M market InduBox PSTN Unblockable ultra stable PSTN communications Industrial PSTN modem with high level electromagnetical immunity In the summer of 2007 Bausch Datacom was asked by metering company Actaris to develop a PSTN modem for the electricity market in Belgium. In this market (in Belgium) the generic EMC immunity standards are not applicable. For example: to test the immunity of GSM and PSTN modems to radiated electromagnetical fields from digital radio telephones Laborelec creates a test environment which generates 30 V/m field strengths in stead of the standard 'normal' field strength of 3 V/m (CISPR24 level = 3 V/m). The result of all these extended electromagnetical immunity tests is the Indubox PSTN, an industrial modem for analogue communiction over PSTN lines in heavy-duty industrial environments. The modem is built in a double sealable housing with transparent lid and has two different and parallel usuable isolated serial interfaces, one RS-232 (3-wire), one RS-485 (3-wire). Removable Phoenix terminal blocks with screw contacts (2-pins plug for mains, 3-pins plug for RS-232 and RS-485 interface) make installation easier. Additional to the electromagnetical immunity to a very high level, the Bausch InduBox PSTN modem has other important industrial features: a wall mountable, non-flammable and sealable housing, a wide range power supply (90-253 Vac), a 3-level watchdog with programmed reset every 24 hours, etc... Those features are not present on standard desktop PSTN modems. The configuration can be done via a standard RJ-45 RS-232 serial interface with 8 contacts via AT-commands. To monitor the status of the InduBox PSTN we have implemented 12 LED indicators. The embedded socket modem is based on Silicon Labs technology (SMD24XX range) and is made by Delta Design, engineering company of Bausch Datacom.
