SYSTEM
This screen allows you to configure one or more signaling systems. These signaling systems will
be used by the Call List and Mode screens to determine when and where decode or encode.
TYPE
When this screen is displayed the cursor is placed on the TYPE data field. The available system
types are QCII (QUIK CALL) and GENERIC. The system types are selected by using the
Up/Down arrow keys.
ID QCII
QCII ID corresponds to tones A and B. It requires at two unique tones. The defaults are 358.6
Hz (tone A) and 903.s Hz (tone B). The range is from 304.0 to 2470.0 Hz. Don't be alarmed if
the frequency that you type in changes by a few Hertz. This change can occur because the
program must calculate the nearest frequency that the radio can understand. You will find that
the error will always be within the acceptable industry bandwidth.
CALL FORMAT
This field is currently forced to be A-B and A-B/Long B.
CALL TYPE
There are three different choices for this field. The Up/Down arrow keys will scroll through the
following choices: Call Alert, Call Alert/Voice, and Voice Selcall. Call Alert leaves call
indication at the receiving radio. Call Alert/Voice leaves a call indication and unmutes the
loudspeaker of the receiving radio. Voice Selcall unmutes loudspeaker on receiving radio but
does not leave any call indication. MDC-1200 does not allow Voice Selcall call type since Voice
Selcall is an inherent feature of all MDC-1200 signalling systems.
