NBOXB/TMNH/UK/230 - Battery backed Trend modem node with 56k integral modem in an enclosure

The TMN allows either networked or stand-alone IQ System devices to access the Public Switched Telephone Network (PSTN) via an integral or external modem, or to access the Integrated Services Digital Network (ISDN) via a terminal adaptor. The TMNG uses wireless communication via a GSM service provider enabling connections to sites without landlines and direct SMS messaging (text messages) to mobile phones. The TMN can communicate either to single or multiple devices over the IQ system current loop Lan. It also supports text messaging and communications to radiopagers via the PSTN and is supplied either boxed, or as a board which can be fitted in other IQ system devices (e.g. IQ controllers). A boxed battery-backed version is available (230 Vac only). There are high speed integral modem, GSM modem, and external modem/terminal adaptor versions.
