The Telex conventional P25 offering complies with Telecommunications Industry Association (TIA) standards for the Digital Fixed Station Interface (DFSI). This interface provides the connection between the C-Soft console and conventional P25 networks operating with the common air interface. Working with Tait and Daniels, Telex is providing a DFSI for digital conventional radio systems. This interface will connect directly to the base station radio and not require an IP-223 or IP-224 to convert audio and control signals to Ethernet. This design does not require dedicated servers in the system, so in a multi-position console system, one position takes the role of control server and another position backs the control up in case of failure. Any of the positions can be configured to be the server and backup, thus maintaining scalability and flexibility in the console system design. All C-Soft features are still available with this design, including Cross Patch, which allows the analog systems to be connected to the P25 systems. The following list outlines the companies and functions offered in this DFSI interface.
