3.12.5 Parallel Operation of the Analog and E1 Audio Interfaces
Introduction
Analog interface functionality remains unchanged when E1 audio interface
is selected (see chapter 3.3).
TX Audio Basic
interface X5
Radio functionality related to the TX Audio Basic interface X5 remains
unchanged when E1 audio interface is selected. Transmitter can be keyed
via E1 interface or using the rear PTT input (connector X5.8/X5.9).
In-Band PTT can be configured on the X5 interface as well (see chapter 3.8
In-Band Signaling).
Note: Analog transmitting via the X5 and E1 cannot work simultaneously.
Only one PTT and audio source are accepted at a time.
RX Audio Basic
interface X10
Radio functionality related to the RX Audio Basic interface X10 remains
unchanged when the E1 audio interface is selected. The received
demodulated audio signal is available on the Analog and E1 interfaces in
parallel.
Note: When in-band signalling is enabled (SQ or RSSI, see chapter 3.8
In-Band Signaling), the tones are present only on the RX Audio Basic
interface X10.
