The AVA-01 is a one voice port adapter available with FXS, FXO, 4-wire E&M or a push-to-talk interface for a speaker-microphone. The AVA-01 is designed for simplicity and ease of setup. The unit can be setup using a serial terminal interface, via an RS-232 or USB connection.
The AVA-01 provides exceptional compressed voice quality at speeds ranging from 2400 to 9600 bps. The compressed voice is based on the same chip set used for Project 25 (P25) radio interoperability. This is a voice chip set that has a very long market life, which translates to a long market life for the AVA. AVA voice choices also includes 56K PCM. The choice of PCM make the AVA-01 suitable for applications that require tone control, such as links to radio transmitters.
The AVA-01 can be ordered with FXS/ FXO/4-wire E&M/PTT or only push-to-talk (PTT) audio interfaces. PTT is included with the FXS/FXO/E&M units. The interface is specified at the time the unit is ordered. The PTT audio interface is supplied with a microphone and speaker for PTT only orders, and as an add-on item for FXS/FXO/E&M units. The speaker circuit has a .25 watt amplifier.
The AVA-01 can also operate over Ethernet networks using TCP/IP. For Ethernet operation, order the "-E" Ethernet option.
All versions include an additional asynchronous RS-232 user port. Via this asynchronous user port, AVA supports both SCADA polling and compressed voice on multidrop networks of 9600 bps and faster. AVA resolves the contention between the polling and the voice. Voice with polling on multidrop circuits uses the push-to-talk mode. Voice is broadcast from the host to all remote AVAs, and from one remote at a time to the host. This mode allows control room to substation conversations without the need for cell phones or substation voice phone lines. (Point-to-multipoint firmware is a future option.)
