Conventional Mode Features
• MDC
Three features use analog signaling:
• Pre and Post ANI
• Emergency Alarm
• RTT
5.12.1 DTMF/ANI Signaling
DTMF (Dual Tone Multi-Frequency) tones can be generated for ANI (Automatic Number
Identification) and other purposes on conventional analog channels. One of the following
options may be enabled on each channel:
Pre-Tx ANI - A pre programmed ANI sequence is automatically sent each time the
PTT switch is pressed.
Post-Tx ANI - A pre programmed ANI sequence is automatically sent each time the
PTT switch is released.
When an emergency alarm or call is placed, this ANI signaling is replaced by the
Emergency DTMF ID (see Section 5.9). Refer to Section 5.12.3 for information on
MDC1200 ANI.
5.12.2 Single Tone Encoder
This feature allows the user to transmit a single tone by pressing the Single Tone Encoder
option switch or selecting that menu parameter. Each conventional system can be
programmed for a tone of 500-2500 Hz in 1 Hz increments with a duration of 0.5-2.5
seconds in 0.1 second increments.
This feature can be activated with a button press or can be used for Pre and Post ANI,
Emergency Alarm, or RTT.
5.12.3 MDC1200 Compatibility
MDC1200 is a signaling protocol designed and implemented by Motorola for analog
channels only. The following features of this protocol are supported. Either MDC1200 or
standard DTMF ANI/Emergency signaling can be programmed on each conventional
system.
Note
This feature is hardware dependent and therefore cannot be added to others by upgrading
firmware).
