Abstract

Caller ID is a telephone service whereby infor- mation, such as a calling party's number or date and time of a call, is embedded in the ringing cycle of an incoming call. By decoding the information at a receiving end, a receiving party is able to identify the calling party and the time at which calls are made.

PAGER WITH CALLER ID FEATURE

by Kwok Lih

INTRODUCTION

  Caller ID is a telephone service whereby infor- mation, such as a calling party's number or date and time of a call, is embedded in the ringing cycle of an incoming call. By decoding the information at a receiving end, a receiving party is able to identify the calling party and the time at which calls are made.

DESCRIPTION

Proposed h~erein is a pager with a caller ID feature. The pager includes a caller ID decoder, for

example, Motorola's MCI45447 Calling Line Identification Receiver with Ring detector IC. A phone jack is provided on the pager for connecting to a phone line. When the phone line is called, the caller ID decoder decodes and displays the information on the pager's display.

  Figure 1 below shows the pager with the caller ID decoder. With the caller ID feature, one more function is enabled for the pager in addition to receiving paging signals.
