Abstract

PURPOSE:To attain automatically an outgoing suitable for an acquisited line by selecting the transmitting state of a dialed number depending on whether the dialed number is transmitted to a trunk line or an extension of a PBX. CONSTITUTION:A line identifying section CDS identifies whether a line acquisited by a telephone set is a trunk line CO or an extension PX of a PBX. Further, a number identifying section NDS identifies whether a dialed number from a memory MEME transmitted from the calling of the telephone set is transmitted to the trunk line CO or the extension PX of the PBX. Then a transmission selection section SSL selects whether the dialed number is transmitted immediately or the dialed number is transmitted after an access code for the PBX is transmitted in response to the result of both identification. Thus the outgoing suitable for the acquisited line is attained automatically regardless of the type of the acquisited line.

Based on the settings of B and the time measurement by the clock circuit in the processor CPU, a "Hayabusa daytime/nighttime switching process" is performed that allows connection of the office lines CO1 to CO5 only to specific telephones ST+ to ST11+ at night.

Next, a timer in the processor CPU performs ◆extension timeout processing, such as canceling the calling state if the other party does not respond even if the calling state continues for, for example, 30 seconds, and then calls from the door phone DRP. If the incoming call fails, ◆Door intercom incoming call processing'' will take appropriate control! Receive data processing'' and subsequent steps are repeated.

) in Fig. 3, interrupt processing is performed at a cycle of 16.5 m5ec, and the above-mentioned cram school daytime/night switching processing is performed by 'TNGHT'.

” is NO, the dial number has not been registered1.
2- Therefore, immediately proceed to "processing operation data from the first telephone."

On the other hand, Taku dial number Rori? If YES to ゛′,
11th digit dial number/readout that appears in the first position”
In addition to doing this, is the captured line connected to the PBX according to the variable memory RAMQ Hibiki? If it is YES, the read out first digit dial number is for the PBX! Does it match the access code? After determining ``, and sending the 61st digit dial number in response to YES, it was smoothly determined! After setting the pause time,
Dial numbers from the second digit onwards, read out, and send 'l'.

Also, does it match the shadow access code? ” is NO, then P
Since the call is to another extension telephone housed in the BX, the dial number from the first digit onward is sent.

Therefore, in the dial memory area corresponding to the telephone STn, when the number is a local number, an access code such as 01 and the dial number of the other party are stored, and when the number is a local number, an access code such as tj:, r91, etc. is stored. If you store the area code and dial number of the other party, and if it is another extension number, store only the extension dial number, and if you memorize the dial number using these, it will match the cram school access code. In response to YES from PBX, the local number or long-distance number is sent to one of extensions PXr to PX3 with the access code at the beginning, and dialing to the central office line is performed via the PBX. If the code matches 7'', only the dialed number of the extension is sent to any of the extensions PX+-PXa.

Also, is the 1 captured line connected to the PBX? Even if the answer is NO,
Does it match the exposed access code? ”, and this is Y.
If it is ES, immediately dial the number after the second digit.
In order to transition to “reading/sending”, the captured station line CO
A local or long-distance dial number, excluding the access code, is immediately sent to the CO2 unit.

On the other hand, is Hayabusa's capture line a PBX extension? If ``Does it match the cram school access code?'' is also No, then ``All lines are connected to the central office?'' according to the settings of the switch board SWB in Figure 1. N
If this is YES, extension PX+ -PX

It is determined that the call is to X+-PXs, and the process moves to ``processing of operation data from the next telephone.''

FIG. 5 is a flowchart showing another embodiment. In addition to operating the off-hook and station line buttons on any of the telephones STn, if a speed dial operation is performed, the speed dial request process including line capture is completed. Then, the flosser CPU searches the corresponding dial memory area in the same way as shown in Figure 4.Is there an exposed dial number? If ``No'' is selected, the process will proceed to ◆Processing of operation data from the next telephone set'', but if YES, the same procedure as in Fig. 4 will be performed. The captured line is PBX extension ν YES'! f As a premise! After performing the first digit 15-Dial number/readout, this is [0
Hayabusa area number depending on whether it is -1 or not? If the answer is YES, for example, perform [9-1 5 Send access code for out-of-town calls], and if the answer is NO, perform, for example, send 0,1 access code for out-of-town calls. Moreover, after setting the 1-voice time, dial numbers and send from the -1st digit onward.

In addition, is the rare captured line a PBX extension? If "is NO," the process immediately moves to "s: Dial number after 1st digit/send."

Therefore, in FIG. 5, only the dialed number of the other party is stored in the dial memory area corresponding to the telephone STn when it is a local number, and when it is an area number, "0" is stored.
It is only necessary to store the area code and dial number starting with ", and the PBX access code will be automatically added accordingly.

FIG. 6 is a block diagram showing the basic configuration of the present invention.

After connecting with s, the line capture state is set.

Furthermore, the information that the cross point of the mfi section cN is turned on is given to the line identification section CDS, and according to the information indicating the line type set by the switch board SWB, the line identification section CDS detects the captured line. This is used to identify the type.

On the other hand, the registered dial number is stored in the memory MEM corresponding to the variable memo') RAM.
Since the control unit CT specifies the read address in response to the operation of TI to S T r s , the number identification unit NDS reads out the dial number stored in the memory MEM.
The type of dialed number is identified here.

The identification results of each identification section NDS and CDS are sent to the transmission selection section S.
