Explicit Other Band Trunking

The ASTRO ^® 25 system uses two methods for defining transmit and receive frequencies on a given channel: explicit and implicit. Channels defined as explicit enable the use of two very different frequencies for transmitting and receiving. When transmitting on a channel using an explicitly-defined frequency, the site sends the Tx and Rx frequencies. Trunking systems typically use a standard 800 MHz full range of Tx/Rx pairs of frequencies. Other band trunking uses frequencies outside of this standard trunking range.
