Abstract
To convert an analog communication between two local access transport areas (LATA's) from one charged at multiple inter-LATA rates to one charged at a single inter-LATA rate plus lower intra-LATA rates, the communication is concentrated within the remote LATA by installing a remote demarcation point connected to a central office and by installing a master station demarcation point and the master station demarcation point are interfaced by an analog concentrator. The analog concentrator couples the analog communication signals by appropriately amplifying them without digital conversion or processing.

An apparatus for communicating analog communication signals, routed through a central office of a telephone system, with a plurality of remote drops in communication with a central office, said apparatus comprising:
- remote means, adapted for connecting to the central office through which the analog communication signals are routed to define a single termination drop with respect to the central office through which the analog communication signals are routed, for receiving the analog communication signals from the central office through which the analog communication signals are routed;
- master station means, located with said remote means and adapted for connecting to the central office with which the plurality of remote drops are in communication to define a single origination drop with respect to the central office with which the plurality of remote drops are in communication, for establishing communications through the central office with which the plurality of remote drops are in communication to the plurality of remote drops and for transmitting the analog communication signals to the central office with which the plurality of remote drops are in communication for communication therethrough to the plurality of remote drops;
- and
- interface means, connected between said remote means and said master station means, for communicating the analog communication signals in analog format between said remote means and said master station means.
An apparatus for interfacing analog signals between a first four-wire private line and a second four-wire private line, said apparatus comprising:
- first amplifier means for amplifying an analog signal;
- first connector means for connecting an input of said first amplifier means to the first four-wire private line so that said first amplifier means receives an analog signal transmitted over two of the wires of the first four-wire private line;
- second connector means for connecting an output of said first amplifier means to the second four-wire private line so that said first amplifier means provides an analog signal to two of the wires of the second four-wire private line;
- second amplifier means for amplifying an analog signal;
- third connector means for connecting an input of said second amplifier means to the second four-wire private line so that said second amplifier means receives an analog signal from the other two wires of the second four-wire private line;
- and
- fourth connector means for connecting an output of said second amplifier means to the first four-wire private line so that said second amplifier means provides an analog signal to the other two wires of the first four-wire private line.
A method of communicating analog signals between a master station, located in a first local access transport area, and a plurality of remote drops, located in a second local access transport area having a central office, said method comprising the steps of:
- (a) defining a remote demarcation point within the second local access transport area;
- (b) defining a master station demarcation point within the second local access transport area;
- (c) transmitting analog signals from the master station in the first local access transport area to the central office in the second local access transport area;
- (d) communicating the analog signals from the central office to the remote demarcation point defined within the second local access transport area;
- (e) coupling the analog signals from the remote demarcation point to the master station demarcation point defined within the second local access transport area;
- and
- (f) communicating the coupled analog signals from the master station demaraction point to the plurality of remote drops in the second local access transport area.
