LAM Level Field
The LAM Level field identifies the threshold, in dB, at which the radio/line unmutes and sends RX packets to the Ethernet.
The range for this field is -50 to +10dB.
LAM Time Field
The LAM Time field identifies the amount of time, in seconds, the console continues to play audio when receiving audio
above the LAM threshold specified in the LAM Level field. This entry is also used by the Ethernet to determine how long to
send audio.
The range for this field is 0 to 60 sec.
The Monitor Relay field provides the IP-223 the ability to decode a valid Ethernet packet and provide a relay-contact output
to turn off the sub-audible-tone-decoder circuit in the radio receiver. This allows the console operator to monitor the line for
other users before transmission (required by FCC regulations on stations equipped with CTCSS).
