Here, extension telephone A (hereinafter referred to as STA A) 1,
I would like to connect with SAT B2, and STA B2
There is a demand for making a call in as short a time as possible even if the person is busy. On this occasion,
STA A1 dials the special number for the call waiting service and then dials the extension number of STA B2. The special number and the extension number of STA B2 are counted and accumulated in the ORT9, and transferred to the CPU6. CPU 6 analyzes the special code and identifies a call waiting service request, and restores the connection on SW 3 (between STA A ← → ORT).
Tone sending circuit shown in Figure 3 (hereinafter referred to as TT)
Connect special ring port 13 to STA A1, and connect special ring port 12 to STA B2.
Connect with the route.

御する。 The special sound is different from the waiting sound of conventional call waiting services and is designed to be clearly distinguishable by the called party. STA B2 plays the above special sound.
If you listen to it during a call with STA C10, you will be able to recognize that emergency call waiting has been set, and you will be able to quickly end the call with STA C10 and answer the call. When the CPU 6 detects the recovery of STA C10, it releases the connection of , , in Fig. 1, and sends a general ring tone to STA A1 as shown in Fig. 2.
It also controls STA B2 to send a paging signal.

ため、発信側の緊急度が理解できる。 The present invention coexists in a private branch exchange with a conventional call waiting service, and when an emergency call is requested, the operation of the present invention is performed, and when a call is not particularly urgent, the conventional call waiting service is operated.
You can also set up call waiting by simply dialing the telephone number of the person you wish to connect to. In this case, the called party's telephone can identify whether it is a conventional call waiting service or a call waiting service according to the present invention by the waiting tone sent out during the call, so it can understand the urgency of the calling party. .
