Industrial communication over a wide area is needed for many industrial applications. Whether it be remote monitoring of control system or extensions to process systems spread over a wide area. We have many applications operating in Africa.

PSTN, ISDN, ADSL, GSM, 3G, Wireless

PSTN PSTN (Public Service Telephone Network - otherwise known as fixed line) products consist of modems that can be connected to the public telephone network.

ISDN: Compared to the PSTN-modems which are used on analogue lines the ISDN are used on digital telephone lines (Integrated Services Digital Network). The big advantage with ISDN is that it can be used for very fast communication, 64 Kbit/s on the line and a connect time of a few seconds.

ADSL routers offer high speed communications with support for Encrypted Virtual Private Networks.

GSM (Global System for Mobile communication) offers a natural and easy platform for wireless automation, using the local service providers cellular network.

3G / HSPA / GPRS / EDGE connection (Third Generation) as opposed to 2G (GSM, GPRS) supports much higher bandwidth of up to 7.2mBit/s data downlink. The Westermo 3G Routers all support multiple functions including Firewalls, SNMP Management etc.

VDSL Router capable of delivering data-rates of around 100 Mbit/s both downstream as well as upstream. The unit has a built in 4 port switch with Layer 3 routing capabilities.

Industrial remote access over the GSM network

For wireless data communications over the GSM network, Westermo have a range of industrial GSM / GPRS modems. Our GSM modems support Circuit Switched Data (CSD) connections and SMS messaging for alarm notifications. All of our GSM modems can also communicate via GPRS and have an embedded TCP/IP stack for connection to the Internet. With support for RS-232 or RS-485 connections, our industrial GSM modems are ideal for serial remote access connectivity.

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.

Reliable remote access with industrial telephone modems

The Westermo range of industrial modems are designed for use in harsh environments and allow remote access connections over PSTN dial up and leased lines / private wires. With support for serial RS-232, RS-422, RS-485 and PROFIBUS protocols our modems are ideal for industrial applications. For security, features such as password protection, dial-back and caller ID answering are included. Whether mounted on a DIN-rail or in a rack, the Westermo modems ensure reliable communications.
