ISDN modems

High-speed ISDN access for industrial applications

The Westermo range of ISDN modems have been developed with high-speed industrial data communications in mind. Our ISDN modems support serial RS-232, RS-422 and RS-485 interfaces and have been designed to meet the European DSS1 standard. All standard ISDN transport protocols are supported including HDLC transparent, V.110 asynchronous, X75, PPP and ML-PPP. The Westermo industrial ISDN modems also feature an internal analogue V.34 modem enabling connections from ISDN to PSTN or GSM end locations.
