Delay Setup

TX Delay Field

The TX Delay field identifies the delay, in ms, of TX audio. When TX Ethernet packets arrive, the PTT relay is closed and TX audio is delayed for the specified time. This provides the ability to overcome timing issues involving repeater attack time or trunking (clear to talk) delays.

The range for this field is 0 to 2000ms.

RX Delay Field

The RX Delay field identifies the amount of time, in ms, RX audio is recorded and stored. RX audio is constantly recorded by the IP-223 and when a LAM or COR, triggered detect occurs, the IP-223 goes back the specified time of delay to start generating Ethernet packets. This provides the ability to prevent lost first syllables using LAM or COR.

The range for this field is 0 to 1000ms.

Squelch Tail Delay Field

The Squelch Tail Delay field identifies the amount of time, in ms, the RX audio is muted after PTT occurs. This provides the ability to overcome squelch tail ping-pong in crosspatch modes by muting the radio RX input after PTT occurs.

The range for this field is 0 to 5000.
