A process for a telephone system is disclosed which is associated with
customer premises equipment, such as a telephone set or other receiving
equipment which has a built-in or attached dual-tone multifrequency (DTMF)
receiver-decoder chip connected to an alphanumeric memory chip which is
connected to a liquid crystal display (LCD) counter, connected via a RJ11
jack and telephone lines to central office equipment, which allows an
incoming caller directory telephone number or any keyed-in telephone
number or name initiated by the incoming caller to be transmitted over a
called customer busy line (i.e. without call-waiting service), idle line
(i.e. with or without call-waiting service) or an in-use line (i.e. with
call-waiting service) and received to the called customer premises
equipment, which is screened and stored to the equipment's memory for
later recall and or redialing. Interoffice and intraoffice application of
the disclosed system can be deployed by signaling methods capable of
transmitting calling line identification or by dual-tone multifrequency
end-to-end signaling. The disclosed system is also designed to interact
with existing customer subscribed to telephone services and features, and
is a revenue producing service intended for residential and cellular
telephone customers.
