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 preprogrammed ANI sequence is automatically sent each time the PTT
switch is pressed.
Post-Tx ANI - A preprogrammed 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 6.9). Refer to Section 6.12.3 for information on
MDC1200 ANI.
