6.1 DTMF system functions
6.1.1 DTMF call initiation via the Audio inputs
You can also initiate a call using DTMF tones via the Audio inputs of the sys-
tem. You simply need to send the DTMF tones from an external DTMF gener-
ator to the Audio input of the MAGIC TH6. To signal the system that the
number is complete, you need to send the dialling command via a TTL Pin
(see Page 54, TTL Pin as input
→ Connect via DTMF/Accept Call In).
