Additional Info

The Proxima ISDN is a standard ISDN Terminal Adapter with a standard V.24 RS-232 serial interface.
Nothing special one would say!
But we use this ‘old’ ISDN technology especially in combination with our Indubox and DinBox GSM data communication solutions: the V.110 ISDN protocol makes really fast digital connections possible between the Proxima ISDN in host configuration and the Bausch GSM devices in the field (see application drawing below). This kind of ISDN (V.110) host communication with GSM data modems in the field  is also much more stable and much faster than communication between GSM modems.
For example, we have an Itron MV-90 xi host application up and running in Belgium were every night more then 150 Proxima ISDN modems read the data of about 25.000 (Bausch Indubox) GSM data modems in the field via the ISDN V.110 protocol.
The Proxima ISDN modems can also be mounted in 19" racks.
