Comtech Targets Machine-to-Machine Apps with PSTN and GSM/GPRS Routers

2/8/2005 - Comtech Holdings Ltd (, the leading Machine-to-Machine (M2M) Solution Provider, announce the release of the µWEBox eRouter family with two products which enable Ethernet-based machines to communicate over public Wide Area Networks (WAN).

  1. The µWEBox eRouter GSM/GPRS Router connects Ethernet devices over wireless GSM/GPRS
  2. The µWEBox eRouter PSTN Router connects Ethernet devices over the PSTN network.

Companies often find it difficult to remotely access a machine deployed at an end-customers site via their Ethernet Local Area Network (LAN). They are prevented by firewalls that isolate public and private networks and often by the end-customers I.T. department who prevent "alien" machines utilising their network. Furthermore, there are many cases where the machine is located in geographical isolated or mobile locations, where no Local Area Network exists.

The µWEBox eRouters overcome these problems by creating a standalone network with its own Wide Area Network (WAN) access point to the public PSTN, GSM, GPRS networks and/or the Internet. The Ethernet port of the remote equipment is adapted by the router for WAN connectivity, which supports "Dial-in", "Dial-out" and "Always Connected" modes of operation. Each µWEBox eRouter provides PPP encapsulation of TCP/IP data and supports Network Address Translation (NAT), IP forwarding, DHCP server, DNS, UDP, PING and ARP protocols. The µWEBox eRouters are housed in a rugged aluminium enclosure and can be operated within a wide 8 to 40 volt power supply range. Available NOW.


"Our PSTN, GSM and GPRS Routers reduce the barrier to sales of ethernet-based equipment, by providing remote access to them where ever they are located; reducing the dependancy on the end-customers network", said Steve Whitehead, Technical Director, Comtech Holdings Ltd. "Not only are the installation and maintenance costs reduced, but new business opportunities can be created by gaining remote access to the important information within the machine where previously this was not possible. As an example, charging for leased equipment may be increased dependant on how and when it is operated, especially if these fall outside permitted limits."

Development Tools - This launch is complemented with the release of a development Starter Kit to simplify evaluation and aid design integration.

Customisation - Comtech offer design customisations for µWEBox eRouter PSTN and GSM/GPRS routers, by incorporating customer and market specific application needs.
