Remote reprogramming system for telephone call forwarding service
First Claim
1. A device for remotely controlling call forwarding for a given telephone line, comprising:
- detecting means for detecting an incoming call to the given telephone line;
a ring counter for counting the number of rings on said incoming call;
detector circuit means producing a first output responsive to receiving no more than a fixed number of rings and a second output responsive to receiving more than the fixed number of rings;
generating means responsive only to said first output for generating a call forwarding terminate code in response to an incoming call;
sensing means for detecting a second incoming call within a preselected time of the first incoming call;
storage means for storing a desired call forwarding telephone number; and
reprogramming means respectively responsive to said sensing means receiving a second incoming call and to said second output for generating a call forward initiate code and thereafter reprogramming call forwarding with said stored number.

Abstract
A device for remotely controlling call forwarding for a given telephone line. The device includes a detection circuit for detecting an incoming call to the given telephone line. If it detects only one or two signals indicating a previous call forwarding initiate setting, it automatically terminates call forwarding and awaits input of a new call forwarding telephone number followed by a security code. If it detects more than four rings, it knows that the call forwarding was not enabled and it is ready to accept the new call forwarding number remotely input along with the security code. After receiving successfully the remotely inserted call forwarding number and security code, it proceeds to reprogram the system with the new call forwarding number. Should any unauthorized user be using the system, it will reprogram with the previously stored call forwarding number.
