Simulator integrates old modems

Digi DialServ extends the life of existing remote equipment by allowing devices to communicate with a centralised location as if they were TCP/IP devices

Digi International has released the Digi DialServ, a phone line simulator that integrates with Digi's cellular gateways to allow legacy devices with built-in modems to easily drop-in to cellular IP networks. Remote legacy devices with built-in modems include devices like programmable logic controllers (PLCs), security panels, automated teller machines and point-of-sale devices.
Digi DialServ extends the life of existing remote equipment by allowing devices to communicate with a centralised location as if they were TCP/IP devices.

Replacing old phone lines with IP communications eliminates the cost of additional phone lines and speeds transaction times.

'The Digi DialServ provides a migration path for customers from old analogue dial-up networks to more efficient, lower-cost wireless IP networks', said Larry Kraft, Senior Vice President of Global Sales and Marketing, Digi International.

'Best of all, customers can get these benefits without changing their applications'.

When used with Digi cellular gateways, the Digi DialServ works with both dial-in and dial-out applications by simulating the Telco network and converting the requested phone number to an IP address.

It makes the device think it is still communicating over Plain Old Telephone Service (POTS).
