Abstract

PURPOSE:To use a privacy telephone set in common from all subscribers of an electronic exchange, by connecting an input/output of the privacy telephone set to a trunk link network of the electronic exchange via an out-band dial signal outgoing/incoming trunk. CONSTITUTION:When a telephone set 1 makes a call, it is connected to an ORT 11, and the 1st dial number 8 reserves a path via an ODBWT8, a privacy telephone set 10 and an ODBWT9. The number dialed from the telephone set 1 passes through an OST14 and is transmitted to the incoming side of an ODBWT7 of a remote station via the outgoing side of the ODBWT7. A call tone is given from a TNT12 via the outgoing/incoming side of the ODBWT7 of both exchanges toward the opposite direction. The calling signal from an RGT13 is given to the imcoming subscriber. When the incoming subscriber responds, the path is switched to the reserved path, allowing to make privacy call between the telephone set 1 and the incoming subscriber with the privacy telephone set 10 inserted between the both.

A case will be described in which a telephone set of one electronic exchange is used to communicate with a subscriber of the other party's electronic exchange (described as Sakuseisha) while the telephone is powered on. Phone l is Il@Shi, 0RTI
When the program identifies the IK connection and the connection to the other party's electronic exchange, the telephone! The number that is a diamond is transmitted through the 08T14 meeting and sent to the input side of the 0DBW〒ma of the other station via the output 11 of 0DBWT7. At this time, the communication +iui between telephone 1 and 0DBW'l'ma is prepared as a reserved path, and is disconnected when the selection digits from 08'l'14 are finished leaving. @0DBW at the exchange at the hand office
Upon receiving the selected numeric tube through the ingress of T7 and identifying the called subscriber, the telephone IK calls from 'rN'l''12 in the opposite direction via the egress ingress of 0DBWT? of both exchanges. Also, a paging signal is sent to the called subscriber from RGTlB.At this time, a reserved path is prepared for the communication path between 0DBWT7 of the other party's exchange and the called subscriber, and the called subscriber answers the call. At that point, the switch switches to the reserved path.Then, for the first time, the call between telephone 1 and the called subscriber goes to 0 on both exchanges.
1) It becomes possible through the BW'r meeting and all other trunk paths are restored. A 41I connection is established between 0DBWT'7 of this time exchange through relay 11. Next, a case will be explained in which a call is desired to be made via secret device 10. The secret device 10 is connected to the input/output of the voice transmitting side and the input/output of the injured side with 0DBW'l'll, ml pipes, and is connected to the trunk link network SKm! It is continued,
The identification number of 0DBWT8.9 is not used for single-station connection, trunk line connection, or intra-station connection; for example, 8 is assigned to the transmitting side and 9 [- is assigned to the receiving side. As a dial number, the first number is 8, and the 8t dial is I, so that 0DBWT8 can be identified (.The next number is a dial number that can identify the relay bell trunk 0DBWT7, for example, 7, Next number company, 0D of the other station
BWI'9 is set as an identifying number 9, and the next number is set as the subscriber number of the partner station. Also, as a program, it is identified by the dial numerals above and is 0DBWT8. Concealment device 10
.. 0DBWT7. Set it to 1 to connect via trunk line communication through 0DBWT7t- of the other party's exchange, 0DBW'r9° secret device xo, and 0DBWT8t-.

At this point, telephone 1 makes a call and is connected to OR#lx, and when the program identifies that the connection is to 0DBWT8 which is connected through the secret device 10 pipe by the first dial 9 number 8, 0DBWT8. Concealment device 10, ODBWTgt
- Neglecting to prepare an intervening path as a reserved path. The next dial number 7 indicates that the connection is to another electronic exchange.
When the program identifies it, the number dialed by the power cutter 1 is transmitted through the 08T14 pipe to the input side of the 0DBWT7 of the other station via the output side of the 0DBWT7. At this time, telephone 1 and 0DBWT8. Secret 1! ffl position 10.0D
The communication path between BWT9°0DBWT7 is prepared as a reserved path, and is switched after the transmission of the selected digits from 08T14 is completed. The destination exchange receives the selected digits through the input side of 0DBWT7, and via the channel control device 6', the program transmits the first digit 9 to the terminating subscriber KW via the 0DBWT9° concealment device 10.0DBWT8t-.
! The next number identifies the called subscriber t.
- Once identified, the telephone l is sent a ring tone in the opposite direction from the TNT 12 via the outgoing and incoming sides of the own exchange's 0DBWT7. Also, the incoming subscriber receives a call g! from RGT 13. The number will be sent. At this time, the other party's exchange (7) ODBWT7,0
DBWT9. Secret WIjI device 10. ■The communication path to the terminating subscriber via the telephone is prepared as a reserved path, and is switched to the reserved path when the terminating subscriber answers. For the first time, the telephone set 1 and the terminating subscriber are able to make a secret telephone call by means of the secret device 1o inserted into both. At this time, the distance between the secret iI jet 10 and 0DBWT7 of both is 0DBWT8'
