·Supplementary Services
MD78X/78XG supports supplementary services of Radio Check, Remote Monitor, Call Alert, Radio Enable and Radio Disable.
·Multiple Languages
MD78X*/78X*G supports 13 languages, including English, Simplified Chinese, Traditional Chinese, German, Spanish, French, Italian, Polish, Russian, Turkish, Greece, Portuguese and Korean, allowing users to select it per their needs.
·One Touch
MD78X/78XG supports One Touch features that comprise of Text Message, Voice Calls and Supplementary Services.
·Scan
MD78X/78XG supports scanning of pure Analog voice and signaling, pure Digital voice and data, and also mix mode scan that comprise of Analog and Digital activities.
·Roaming
MD78X*/78X*G supports automatic roaming of all sites in a IP Multi-Site Connect systems.
·Privacy of Voice and Data
MD78X/78XG supports Analog scrambling, and digital encryption using Advanced Encryption Standard (AES) and ARCFOUR (ARC4) encryption methodology to both voice and data.
·Analog/Digital Telephone Interconnect (via DTMF signaling)
MD78X/78XG supports simplex voice communications between radio and telephone users. It allows a radio user to make a telephone call; or a telephone user to make either a Group or Private call to radio users. This feature utilizes the Commercial Off The Shelf (COTS) Analog Phone Patch boxes and a Plain Old Telephone Service (POTS) line to connect the radio users to the Corporate Office Phone System (PBX) or Public Switched Telephone Network (PSTN).
·Software Upgradable
With this capability, you can enjoy firmware upgrade without purchasing a new piece of radio hardware!
