Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a control system for controlling abbreviated dialing from an attendant, and in particular, an abbreviated dialing by one or more operations, also called auto dialing (hereinafter referred to as "auto dialing"). This relay system uses existing lamps and numeric information receiving means to control the speed dialing (collectively referred to as speed dialing), and has a simplified configuration while allowing playback dialing information to be sent directly from the relay stand. This invention relates to a speed dial dialing control system.

Conventionally, when making a speed dial call from a relay stand, a common control unit decodes the speed dial information to create playback dial information, and transmits the playback dial information via a PB signal transmission sender trunk PBOST (hereinafter abbreviated as PBOST). It is designed to be sent to COT (central office trunk).

For this reason, a dedicated circuit configuration is required to send reproduction dial information from the common control section and operate a relay circuit in response to the reproduction dial information.

The present invention focuses on the point that the relay console is equipped with a relay console control device that receives rung/numeric information from a common control unit,
The above playback dial information is directly notified from the common control unit to the relay console using the empty bits in the lamp/numeric information, and the relay console directly passes the OPT (operator trunk) to the COT (
The purpose is to simplify the necessary configuration by making it possible to send data to a central office line trunk).

Therefore, the relay stand speed dial transmission control system of the present invention is equipped with a relay stand that has a short dial function by pressing a button and has a relay stand control device that receives lamp and numeric information from a common control unit. In an automatic switchboard connected to a central office line trunk via a handler trunk, the common control unit terminates the speed dial information transmitted by the speed dial transmission function and reproduces dial information corresponding to the speed dial information. is notified to the relay console via the relay console control device, and the relay console controls the push-button signal transmitter built into the relay console in correspondence with each digit of the reproduction dial information to send the operator trunk to the relay console. It is characterized in that the information is sent to the central office line trunk via the above-mentioned network.

This will be explained below with reference to the drawings.

Conventionally, operations such as push buttons 5 on the relay stand 3 are read by the common control section 2 via the seat control device 4 and the scanner 7, and lamp numeric information from the common control section 2 is read by the signal driver 8 and the seat control section. The relay console 3 is notified via the device 4.

When making a speed dial call using such a relay stand 3, it can be considered that the conventional process is as follows.

That is, (1) When the operator makes a speed dial call from the relay console 3, the common control unit 2 is sent via the scanner 7 or another route not shown.
detected by.

(2) The common control unit 2 decodes the abbreviated dial information and generates a playback dial announcement corresponding to the abbreviated dial information.

(3) The generated speed dial information is sent to the PBOST 12 via the sequential driver 11, and the PBOST
12 to network 1.

(4) After that, the relay stand 3 performs the necessary call via the OPT 9.

In the case of this conventional method, a configuration is required for sending the playback dial information generated by the common control unit 2 to the PBOST 1 2 via the signal driver 11, and for the PBOST 12 to send the playback dial information to the network. .

The present invention focuses on the fact that the relay stand 31 itself has the function of receiving lamp and numerical information from the common control unit 2, as described at the beginning of this specification, and Make it possible to omit the configuration.

That is, the common control unit 2 transfers the reproduction dial information generated as described above to the conventional lamp/numeric information transfer method. The signal is sent back to the relay stand 3 via the signal driver 8 that was used for the purpose.

As a result, the relay stand 3 directly sends the reproduction dial information to the COT via the OPT 9.

In FIG. 2, numerals 3, 4, 6, and 8 correspond to those in FIG. 1, 13-0 to 13-m are driver transistors, 14-0 to 14-m are pair lines, and 15 is a memory.

Note that ph0 to ph2 and pI0 to pl3 respectively represent the relay contacts of the corresponding relays.

As mentioned above, conventionally, in order to transmit lamp and numerical information from the common control unit 2 shown in FIG. 1 to the relay stand 3, the signal driver 8 and the seat control device are used as shown in FIGS. 4.

The relay stand 3 is equipped with a relay stand control device 19, and the lamp 6 is turned on for display.

That is, the driver transistors 13-0 to 13-m in the signal driver 8 are selectively turned on, and lamp/numeric information is supplied to the write circuit 15.

Then, it is written into the memory circuit 16 via the write circuit 15.

The contents of the memory circuit 16 are read out via a circuit 17 and sent to the relay console controller 1 via a transmission line 18 in bit serial form.
9 will be notified.

In the relay stand control device 19, the lamp/numeric information transmitted bit-serial is converted into parallel information and guided to the drive circuit 21.

As a result, the drive circuit 21 lights up the lamp 6 as necessary.

In the case of the present invention, attention is paid to the fact that there is a conventional means for transmitting the above-mentioned lamp/numeric information to the relay stand, and by utilizing this means, the above-mentioned playback dial information is transmitted to the common control unit for each digit. 2 to relay stand 3 and directly OPT from relay stand 3
The data is sent to COT via .

Conventionally, the above-mentioned lamp/numeric information has been designed to constitute one frame with 512 bits in sequence.

Figure 3 is an example of a lamp/numeric information array, where 256 bits are used as lamp information and 4 bits are used as numerical information.
[digit]×8 bits are used.

Therefore, the remaining 224 pits remain vacant.

Since it is sufficient to use 4×3 bits as described later to transmit the reproduction dial information digit by digit, there is no technical problem in using the vacant bits.

When transmitting one digit of playback dial information, the first

In the case shown in FIG. 2, one digit of reproduction dial information is transmitted by this combination.

In the case of the present invention, the above-mentioned lamp/numeric information and one digit of reproduction dial information are transmitted from the common control section 2 to the relay console control device 19 via the signal driver 8 and the seat control device 4.
transmitted to.

As a result, one or more of the driver transistors 22-0 to 22-n in the drive circuit 21 are selectively turned on.

For example, when the reproduction dial information "03......" is sent, the relays PL3 and PH1 shown in FIG. will be energized together.

At this time, the contacts pl3 and ph1 are switched from the illustrated state.

Therefore, relay operation detection circuits 32 and 33 complete a current path in series, and relay LH is energized.

On the other hand, in the push button signal transmitter 34-1, the contacts pI3 and p

-2, and sends a frequency combination signal corresponding to the first digit "0" to the OPT 9 (FIG. 1) via the communication line 36.

Next, in response to the second digit "3", both relay PLO and relay PH2 shown in FIG. 2 are energized.

At this time, contacts ph0 and ph2 switch, and relay LH
is energized.

As a result, a frequency combination signal corresponding to the second digit "3" is sent to the OPT 9 via the push button signal transmitter 34-2.

As explained above, according to the present invention, the reproduction dial information is transmitted to the relay console by using the existing lamp/number information reception control device provided on the relay console as is, and the relay console I am trying to send it directly to the network.

Therefore, the configuration within the dashed line shown in FIG. 1 can be omitted.
