Caller Number Delivery (Caller ID)
Caller Number Delivery (CND), commonly called Caller ID, is a phone service that may be offered by your
local phone company. Check your phone company for availability. You must subscribe to it and usually pay
an additional monthly service charge for this service.
With CND service, the phone company's central office sends the coded caller information to the called
station. This information is sent once between the first and second ring. Your modem can decode this caller
information and present it to the connected computer/terminal during the second ring period as part of the
call progress ring message. The modem also reports the Caller ID information if asked by the command
AT*T.
There are two kinds of caller information message formats sent by the phone company.
One is the single message format that includes date, time, and caller ID.
The other is the multiple message format which also includes the caller name as registered with the
phone company.
The command ATS40.2=n is used to enable (n=1) or disable (n=0) the Caller ID detection function. The
default is disabled. Enable it only when you have this service and want to enable its detection.
The Caller ID message may cause some communication software that is not
expecting it to become confused. If you plan to use the Caller ID feature, be sure
you are using software that supports it.
In single message format, the modem sends a ring message to the terminal as follows:
RING
TIME: <MM-DD hh:mm>
CALLER NUMBER: <CALLER_ID> or CALLER NAME:<CALLER_NM>
RING
MM is the two-digit month message, DD is the two-digit date message, hh is the hour and mm is the minute
of the time, and CALLER_ID is the phone number of the caller or CALLER_NM his/her name.
