Receiver
Mode
- VOX
- Voice Operated eXchange detects the presence of voice to signal whether or not audio is being received from the radio. When using VOX it is possible that some clipping at the beginning and end of the transmission can be clipped. VOX has both a sensitivity level as well as a hang timer to detect brief pauses in transmission. When using VOX it is entirely possible that another endpoint is transmitting, however, if the VOX threshold is not met, the channel may never be detected as keyed.
- COS (also known as COR)
- Carrier Operator Squelch is used for mobile radios. When a radio receives a transmission it will send a signal to the AM360 box that tells it the radio is currently keyed. COS is far superior to VOX and is also the preferred mode of operation for devices connected to the ReadyOp platform.
Receive Gain (0-63)
The amount of volume/gain by which incoming audio traffic is increased.
VOX Threshold [VOX Only]
The VOX sensitivity level, the higher the setting, the more audio volume is required to signal the AM360 that the radio is receiving a transmission. The lower the setting the more sensitive the AM360 receiver is to incoming transmissions. If set to 0, the AM360 will be locked in a receiving mode, regardless of whether or not an actual transmission is being received. The default, and recommended setting is 1.
VOX Hang Time (0-25.5 Seconds) [VOX Only]
The amount of time the AM360 should stay in a receiving keyed state after the VOX Threshold has been reached. The recommended setting is a value between .50 and 1 second. If set lower, it’s possible that during a transmission when brief pauses in communication/voice traffic are received, the AM360 will switch between a receiving and idle state.
COS Polarity [COS Only]
Either HI or LO. This is the type of signal the AM360 should expect to receive when the radio is keyed in a receive state. This is also a configurable setting on most mobile/portable end units.
Smart Silence Detection [COS Only]
When set to ON, COS will be used to signal the ReadyOp platform that the radio is keyed. However, VOX will also be employed to regulate network traffic. If voice/audio traffic is not detected, audio frames will not be transmitted to the network. The recommended setting is ON for increased bandwidth savings.
Transmitter
Mode
Half Duplex or Full Duplex. Currently the only supported mode for the ReadyOp platform is Half Duplex.
PTT Polairty
Either HI or LO. This is the type of signal the AM360 should sent to signal the radio that it should be keyed in the PTT state.
The amount of volume/gain that should be applied to audio before it is transmitted through the radio.
PTT Forced Release Timeout (0-25.5 Minutes)
The maximum amount of time the radio is allowed to transmit before the squelch timer will de-key the radio and stop transmitting.
PTT Release Hang Time (0-25.5 Seconds)
The amount of time the AM360 should keep the radio keyed in the PTT state after the transmission has ended.
PTT Anti-Chirp Timer (0-2.55 Seconds)
The amount of time audio should be held/buffered before sending to the radio for transmission. This is used to prevent the first part of a transmission from being cut off on radio systems that take a moment to receive a keyed (PTT) audible/signal.
