[LB022203], Letter from Alfred Ord Tate to William F Taylor (Pennsylvania), Pennsylvania Railroad, June 15th, 1886
Editor's Notes
Mr. Edison has handed me your letter of 12th inst. asking for information relative to the Phonoplex. In reply I beg to say that we do not run phonoplex circuits of over one hundred miles, or thereabouts, in length. On a wire three hundred miles long we could give three additional circuits, entirely independent of the morse, and of each other--the first starting from the initial office of the line and continuing a distance of one hundred miles; the second starting where the first ended and running a like distance and the third following in turn under similar conditions. All or any intermediate offices may be equipped with the phonoplex. We can also give an additional circuit between any two offices on a wire, the distance between which not exceeding our limit, without regard to their location on a morse wire, and include or exclude intermediate stations. ## The phonoplex simply furnishes an additional circuit on an established wire--the same as though a new wire had been strung. There is no interference with the morse, nor does the latter interfere with us. The cost for equipment is about $35.00 for each office furnished with a complete set of phonoplex instruments and $9.50 for each "blind" office--that is a station which is shunted only. ## The terms of our contract granting liscence to corporations to use the phonoplex, are such that we furnish four complete sets of instruments for the equipment of a circuit, and put the same in operation at our own expense by means of our own experts who also instruct permanent employees--after which if the same proves satisfactory the instrumetns are paid for by the parties who use them. ## Annual Royalties are payable as follows: ## For each phonoplex circuit created on wires upon which are employed simple morse instruments, one hundred dollars ($100). ## For each phonoplex circuit created on wired upon which are employed duplex instruments one hundred fifty dollars ($150) and for each [circuit?] on wires on which are employed quadruplex instruments, Two Hundred Dollars ($200) ## The instruments you buy direct from the Manufacturers, with the exception of the four sets [???] which we would ready we will be glad to send you [???] unless in the interim you desire to take some action with regard to increasing the capacity of your lines--in which case we shall be glad to supply you immediately with all further information that you may deem necessary in order to reach a decision.
