5.5.5 Telephone Numbers
The DAI-2 is capable of dialing up to four telephone numbers of 15 digits each when an alarm condition is detected.
These numbers are programmed from address 256 through 315. The DAI-2 will dial the numbers, in rotation, up to four
times each or until the alarm condition is cleared by user input. It sends the identification tones as its alarm message
during the call. The DAI-2 then pauses between calls in case station personnel are trying to call it. The length of a
call and the length of a pause between calls are programmed at address 340 and 341 respectively. The number of
call attempts is programmed at address 342. The alarm system may be enabled or disabled at any time through
programming at address 355.

5.5.6 Automatic Level Control (ALC)
The DAI-2 does limited audio processing through an internal Automatic Level Control (ALC). The ALC is always
active when the DAI-2 is feeding audio to the telephone line to keep audio within legal tolerances. When audio comes
from the telephone line to the DAI-2, the ALC can be frozen at a specific gain setting or disabled through programming
in the Command Matrix. The ALC characteristics are user programmable starting at address 343.
