Abstract
Abstract A miniaturized DNR monitoring device is adapted to communicate over a telephone line, or otherwise, with a remote unit which may also communicate with other monitoring units. The monitoring device includes a computer chip program to select target DNR data from non-target DNR data, a memory for storing a limited amount of data, a DNR output line, means for downloading stored data over its output line to its remote unit on command or upon the occurrence of preselected events, and means for identifying transmissions to and from its remote unit by a handshake routine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
151 words
In an apparatus for dialed number recording monitoring device connected to the line at the target for detecting data from the line, the improvement comprising: (a) storage means in the monitoring device for storing a limited amount of dialed number recording data detected by said monitoring device; (b) means in the monitoring device including a clock for identifying each item of target dialed number recording data; (c) microprocessor means in the monitoring device capable of selected target dialed number recording data from non-target dialed number recording data detected; (d) memory connected to said microprocessor means and containing a program for calling, answering and downloading at least one of data in said storage means, data identifiers and selected target dialed number recording data, through a data transmission line; and (e) a data transmission line for at least one of calling, answering and downloading stored dialed number recording data to a remote unit.
Claim 2
Dependent Claim

Claim 8
Dependent Claim
20 words
Apparatus of claim 3 including means for recognizing a handshake signal received over said dialed number recording data transmission line.
Claim 9
Dependent Claim
22 words
Apparatus of claim 3 including means for transmitting a handshake signal over said dialed number recording data transmission line prior to downloading.
Claim 10
Dependent Claim
35 words
Apparatus of claim 1 including means for downloading data in said storage means into said dialed number recording data transmission line on receipt of an incoming signal on said dialed number recording data transmission line.
