Phase 4 Design is typically involved in custom or very unique system layouts. That very fact often requires us to develop custom adaptors and enclosures. In addition all of our projects have a network component and require custom software configurations.

If you have worked with multiple versions of a software product like C-Soft; you know how having the correct files can be a lifesaver. As a solution, we have developed the concept of a toolbox to represent the collection of files associated with a single version of C-Soft. Each version of toolbox has the official versions of all Telex Software released at the time that version of C-Soft was released. In addition there is a few hundred MegaBytes of technical information regarding Telex Radio Dispatch products and tools that relate to RoIP system maintenance. A toolbox version is currently available for C-Soft versions 6.2 through 8.50.

The toolbox is free to authorized users and requires a username and password to access. Contact us for more information.

There are many free downloads on this page that are meant to be an aid to understanding and maintaining a Telex Radio Dispatch System. We have included past technical presentations, service bulletins and service aids.

This page is dedicated to listing information that make it easier to use and maintain a TELEX RADIO DISPATCH System.

IP/DSP-223 to IP-224 Upgrade Adapter

This new adapter allows an IP-224 to be directly connected in place of an IP-223 or DSP-223 with the existing radio cables intact.

Think of the time you save in an upgrade to IP-224s, use an adapter or re-cable your radios. The IP/DSP-223 to IP-224 Adapter has been tested with radios such as the Daniels MT-x series of base stations and have maintained full functionality with the new hardware.
