This chapter describes the special features of the Comet 336, and offers instructions on
how each is used.
Caller Number Delivery (Caller ID)
Caller Number Delivery (CND), commonly called Caller ID, is a new kind of phone
service that may be offered by your local phone company. Check your phone company
for availability.
With CND service, the phone company’s central office will send the coded caller
information to the called station. This information is sent once between the first and
second rings. The Comet 336 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.
There are two kinds of caller information message formats sent by the phone company:
•
One is the single message format which 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.
