TELEPHONE-EXCHANGE SYSTEM.
Specification of Letters Patentv Patented April 30, 1907.
Application filed November 1, 19%. Serial No. 230,944.
To (til/ whom, it 112/114, cont/141' Be it known that I, Jonas: ANTON AvizN, a subject of the King of Sweden, residing at Stockholm, in the Kingdom of Sweden, have invented new and useful Improvements in T elephone-Exchange Systems, of which the following is a specification.
My invention relates to a telephone call distributing system and is materially distinguished from the usual systems of that kind by the manner in which the work to be done is distributed.
As is well known, hitherto two operators, the so-callec distributing and connecting operators have both to handle each one .plug. The distributing operator upon receiving a call inserted a plug into the answering jack of the calling subscribers line, said plug being connected with another plug at the connecting board, wherea'fter the connecting operator answered the call of the calling subscriber and completed the connection wanted. According to my invention, however, a connection between two subscribers is eil'ected in quite another manner. The operator who receives the call and Whom I will designate as annunciator operator has no plug at all. At her place only annunciators, such as drops or lamps, are provided and further means for communicating to the connecting operator the number of the calling subscriber. This means for communicating the number of the calling subscriber to the connecting op erator may consist for instance in an order circuit extending from the head set of the annunciator operator over a key to the head set of the connecting operator, or of figure indicators, pointers orthe like. The connecting operator upon receiving the number i of the calling subscriber inserts her answering plug into the jack of the calling subscribcrs line provided at her place and makes then the connection in exactly the same way in a usual telephone exchange, 'i. e. as in a telephone exchange wherein each connection is made by only one operator. From the exchange of the latter system my invention differs by the fact that the annunciators are all combined in a special board and have a special operator attending the same. B y this arrangement an essentially greater speed of the work is obtained, as the annunciator operl l l ator has only to attend to the line signals but not to the cut oil signals and as she can always select a free connecting operator for establishing the wanted connection. Furthermore, according to my invention answering jacks are fully dispensed with, the multiple jacks at the connecting board serving as well for answering as for connect,- mg.
In the accompanying drawing the subject matter of my invention is diagrammatically illustrated in one form.
The subscriber stations, two of which O, D are illustrated, are connected with the multiple jacks c, 0 a and (Z (Z (Z respectively and with the armatures o'l cut-oil relays a, b. The lines 1 and 3 extend from one armature of the corresponding cut-oil relay 6t, 1) directly to one pole of the central battery 2, while the other subscribers lines 2, 4 extend to the other pole of the battery 2 over a line relay (1 and 0, respectively, the line relays controlling the lamps f, g. All the line signals are combined in a special board which I will designate annunciator board, while all the jacks are combined in another special board, which I will call connecting boarc Of course each subscribers line has a jack in every section of the connecting board. The annunciator operator A is provided with the usual head set i, a plurality oi" keys 3' and a plurality o'l busy signals Ir. Each oi the latter is connected with one position at the connecting board and shows whether the operator at the latter position is busy or not. The cord system of the connecting operator I may be arranged in any of the usual manners but has in addition a relay m and two springs a a in the combined listening and ringing key 0. y) is the head set, (1 the ringing machine, 2 the central battery, which may be ofcourse combined with the battery .2 to a single one, '7' an impedance coil. 8, s are the clearing-out signals and L, t the answering and connecting jack respectively. Each position at the con necting boa-rd B is further provided with two relays a, o and a so-callcd position switch w.
The operation is as follows: It the subscriber C wants for instance to be connected with the subscriber D, he takes his receiver from its hook, whereupon the line relay (1 attracts its armature so that the circuit of strument in an annunciator board and a terthe line lamp f is closed. On seeing the line necting board for answering the call, testing lamp f lighted up, the annunciator operator the line of the wanted subscriber, ringing the the lamp kof which is latter up, and connecting the calling sub- A presses such a key y not lighted up and thus indicates the correscriber with the wanted subscriber, and
means for communicating from the annunsponding connectingoperatorBas flee. The
ciator board to the connecting board the lamp 7c forms a part of a circuit containing the number of the calling subscriber; whereby a armature of the relay 1; of the corresponding I connecting operator B. As long as the latconnecting operator is notified by an annunciator operator to make a connection, subter is not busy, her relay m has no current so that the following circuit is closed: the free stantially as described.
2. In a call distributingsystem comprising pole of battery 2, 5, one armature of m, 6,
telephone lines, each having a signaling inarmature of u, i), w, ground. Therefore the armature of the relay 1) is attracted as long strument 111 an annunc ator board and a ternnnal socket in each of several sections in a the operator B is free. By pressing the key multiple connecting board, means at the cony' the operator A connects first her head necting board for answering the call, testing set '5 over the wires 7, 8 and two armatures of the relay m with the head set p of the opthe line of the wanted subscriber, ringing the latter up, and connecting the calling suberator B, and secondly closes the circuit of the relay a over the springs y' y' of her key y'. scriber with the wanted subscriber, order wires extending from each annunciator op The relay it attracts its armature and breaks the circuit of the relay 2) so that the armature erator to a plurality of connecting oiperators, and signaling circuits extending om the of the latter falls back and closes the circuit connecting operators to the annunciator opof the lamp 7s, which is of course bridged to similar lamps at the other positions at the erators; whereby a connecting operator is annunciator board. Hereby the operator B notified by an annunciator operator to make is indicated as busy not only at the position of a connection, and the annunciator operators the operator A but also on the other positions are apprised of the readiness of a connecting at the annunciator board. The operator A operator to make connections, substantially now tells the number of the calling subscriber as described.
0 to the operator B whereupon the latter 3. Inacall distributing system comprising telephone lines, each having a signaling ininserts the answering plug 25 into the jack 0 at her position, which is connected with the strument in an annunciator board and a terminal socket in each of several sections in a calling station, inquires the number of the subscriber wanted D, makes the busy test of multiple connecting board, means at the connecting board for answering the call, testing the line of the subscriber D and rings him up. By the insertion of the answering plug it into the line of the wanted subscriber, ringing the latter up, and connecting the calling subthe jack 0 the circuit of the cut-off relay a is closed in the usual way over the sleeve strand, scriber with the wanted subscriber, order wires extending from each annunciator operator so that the line lamp f extinguishes. By throwing the key 0 into the listening posito aplurality of connecting operators, signaling circuits extending from the connecting tion (to the left) the springs 71}, 12, make contact and thus close the circuit of the relay in, operators to the annunciator operators, said which receives current on the following way: free pole of 2, 5, m, n n ground. The relay m therefore attracts its three armatures and breaks thus first the connection between the two head sets i, p of the operators A and B, and secondly the connection between the wires 5 and 6. The latter arrangement has for its purpose to prevent the relay '2) from being excited even after the armature of the relay a has fallen back in consequence of the fact that the operator A has released her key j. l/Vhen the connect ing operator B leaves her place, she pulls the i plug w out, which is associated with the I switch to, so that the latter is opened. In
this manner her position is indicated as busy,
relay at the annunciator board controlling said signals; whereby a connecting operator is notified by an annunciator operator to make a connection, and the annunciator operators are apprised of the readiness of a connecting operator to make connections, sub stantially as described.
4. In a call distributing system comprising telephone lines, each having a signaling in strument in an annunciator board and a ter minal socket in each of several sections in a multiple connecting board, means at the connecting board for answering the call, testing the line of the wanted subscriber, ringing the latter up, and connecting the calling subthough it is not occupied. scriber with the wanted subscriber, order claim: I wires extending from each annunciator op- 1. In a call distributing system comprising erator to a plurality of connecting operators, telephone lines, each having a signaling in- I signaling circuits extending from the connecting operators to the annunciator operators, said signaling circuits containing signals at the annunciator board and a switch minal socket in each of several sections in a multiple connecting board, means at the con- I signaling circuits containing signals and a and a relay at the connecting board controlling said signals, whereby a connecting operator is notified by an annunciator operator to make a connection, and the annunciator operators are apprised of the readiness of a connecting operator to make connections, and whereby a position at the connecting board can be notified as engaged at the annuneiator board if said position is not attended to by an operator.
5. In a call distributing system, comprising telephone lines, each having a signaling in strurnent in an annunciator board and a terminal socket in each of several sections in a multiple connecting board, means at the connecting board for answering the call, testing the line of the wanted subsc'riber, ringing the latter up, and connecting the calling subscriber with the Wanted subscriber, order Wires extending from each annunciator operator to a plurality of connecting operators, signaling circuits extending from the conrials at the annunciator necting operators to the annunciator operators, said signaling circuits containing sigboard and being controlled by a relay, a second relay controlling the said relay and being itsel'l controlled by the key of the annunciator operator, a third relay placed at the connecting board and con trolling also the lirst relay and the order circuit; whereby a connecting operator is notified by an annunciator operator to make a connection, and the annunciator operators are apprised of the readiness of a connecting operator to make connections, substantially as described. 1
