Station for power line access data system
First Claim
1. A central station for a two-way communication system utilizing a power distribution network as the communication medium, said system comprising a plurality of multi-level, addressable repeaters, said central station comprising:
- coupling means for coupling the central station to said power distribution network;
transceiver means coupled to said coupling means for transmitting and receiving signals between said central station and said two-way communication system;
teletypewriter buffer means for transferring information between said central station and a data processing computer;
decoding logic means coupled to said transceiver means for decoding tone code signals from said system;
data handling means coupled to said decoding logic means and said teletypewriter buffer means for monitoring data from said system and storing control information from a computer by way of said teletypewriter buffer means; and
tone generating means coupled to said data handling means and said transceiver means for generating address selection tone codes, selecting a particular communication path through said network under the control of the information stored in said data handling means.

Abstract
A central station is described which acts as an interface between a two-way communication system superimposed on a power distribution network and a data processing computer. Information from the computer is converted into control signals for activating various sequences of sub-tasks by the communication system. Information from communication system is temporarily stored, converted into a suitable code, and transferred to the data processing computer by way of a teletypewriter terminal. Provision is also made for receiving and responding to priority signals from the system.
