The Telex P25 Console Subsystem Interface (DFSI) option is TIA-102 compliant and allows up to 24 lines of C-Soft to connect directly to either Phase I or Phase II P25 trunked systems, thus eliminating the need for a radio gateway product such as the IP-224. Since this is a direct IP wireline connection, it can utilize the low distortion Enhanced IMBE (AMBE+2) vocoder. All C-Soft features are still available with this design, including Crosspatch, which allows legacy analog systems and/or other digital radio systems to be connected to P25 systems. Optional FIPS140-2 compliant AES-256 bit encryption is available for use with the interface.
