Use the encoder to select the level. Press the DISABLE soft key to quickly disable the
beep. Press the DONE soft key to effect the change and exit the menu.
NOTE: The lowest setting for the level is OFF which means that no audible beep is
emitted when the system is recording the line.

Figure 31: ALI/ANI Setup Screen
This screen is used to set the source of line information: CID (internal caller ID recovered
from the line), Automatic Number Information (ANI), and Automatic Location
Information (ALI). When set to Internal (CID), circuitry in the DIR911t uses Caller ID
to extract the ANI information and presents it on the screen. When set to out of band,
circuitry external to the DIR911t is responsible for recovering the ANI information and
sending it to the unit via the ANI serial ports.
When set to ANI, circuitry external to the DIR911t recovers the Caller ID information
and sends it to the unit for display. The serial message format is identical to Caller ID
(the only difference being that the circuitry used to demodulate the CID information is
external to the unit).
When ALI data are available, the DIR911t can extract the telephone number
identification of the calling party from the data. You will need to set the line number,
column number, and the length of the incoming caller’s phone number. Using these
parameters, the DIR911t will extract the phone number from the ALI serial byte stream.
Here is an example of an ALI data stream and how you would set those three parameters:
