Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connection method for a hakama storage phone in an automatic private branch exchange.

In conventional automatic private branch exchange equipment, when installing a special number telephone with fewer digits than the general extension number to facilitate dialing for callers, a dedicated Hakama number trunk is used as shown in Figure 2. was set up, and the Hakama number telephone was called by dialing the mobile number using the marker's route call connection. This conventional method requires a dedicated special number trunk device and an identification relay in the marker for route origination connection, and because it uses the outgoing line of the call path switch, it is uneconomical, such as reducing the number of other trucks loaded. It was hot. In order to solve these drawbacks, the present invention accommodates the special number telephone on the extension telephone side of the call path switch in the same way as the general extension telephone, eliminates the need for a samurai track, and makes it independent of the setting of the number of outgoing lines. Expand the caller's Samurai number dial to a general extension number at the calling register, convert it to general extension interconnection and processing information of the same machine, activate the marker, and connect it to the same sequence as the general extension interconnection to the mobile phone. This feature is characterized by eliminating the need for a route identification relay for special storage telephones in the marker by making a connection with the telephone, and will be explained in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the circuit of the present invention, in which a part of the transmission register is extracted to show the parts necessary for the present invention.

AS is a relay that identifies the first steering wheel, BS is a relay that identifies the second steering wheel.
The MST identifies the steering, and the MST identifies the marker activation, as. ~as2 is the AS relay contact,

Figure 2 shows the relay method of the conventional Hakama number telephone connection system, where EXTA is a general extension telephone, EXTS is a Hakama number telephone, SPT is a special number trunk, OR is a calling register, and SW
is the communication path switch. FIG. 3 shows a relay system showing an embodiment of the hakama number telephone connection system according to the present invention, in which lOT is an extension mutual trunk, and EXTS. OR. SW is the same as in FIG. FIG. 4 is a time chart, in which time chart 1 shows the case of a general extension connection operation, and time chart 2 shows the case of a mobile number telephone connection operation according to the present invention.
A, B, C, CA, AS. BS and MST are the same as in FIG. In the conventional connection method, in Figure 2, the caller EX
When the TA raises the handset and urges the OR, asks for the calling fee, and dials the special number of the called special number telephone EXTS, it activates a marker (not shown) and uses the route identification relay for the special number telephone to indicate that the marker is a Hakama number connection. It identifies and captures the SPT accommodated on the outgoing line T side of the communication path switch SW and sends it to EXTA-
Create an SPT-EXTS connection path and make a call.

Below, before explaining the special number telephone connection system according to the present invention, the general extension interconnection operation will be explained as shown in FIGS. 1 and 3.
In the figure, the calling party EXTA picks up the handset, picks up the OR, hears the dial tone, and selects the called party's extension number, e.g. 32 flea 1.
When you dial the number "3", it is received by A relay and A
When the relay is restored, the C relay operates, and the B relay remains operational, so the ICO output is cleared and the CA relay is operated.

Clear the ICO by operating the CA relay and prepare for counting. When the A relay operates, “1” is counted and the following A
Counting is performed one after another as the relay is interrupted, and finally “

The AS relay operates in the l-cal-D16-TRO-AS-48V battery path. The CA relay slowly recovers when the C relay recovers. The operation of the AS relay sends air to the input of IC2■ through the aso contact, and latches the ICI content '3}. Next, dial the unit number “2” and the I

” is counted. When the C relay operates, the earth-ge-c
1-D17-as2-BS--The Satoshi relay operates in the 48V battery path. When the dial is finished and the C relay is restored, Jiki-bl-cl mountain D18-戊1-MST--48V
The MST relay operates on the battery route, and when the CA relay is restored, the marker is activated on the BL-CL-CAL-M route, the MC relay operates, and the called party information is transferred to connect the extension lines. A connection path of EXTA-1OT---EXrB is created.The above time chart is shown in time chart 1 of FIG. 4.Next, the special number telephone connection method according to the present invention will be explained.

If a special telephone number is provided, a number is set and a connection using the number is made outside the calling register. For example, set the number 6 as a single digit. Connect the engineering terminals a and b and c and d as shown by the dotted line connections in Figure 1. When the calling party EXTA connects with the special number telephone EXTS, the procedure is as described above until EXTA picks up the handset, seizes the OR and hears the dial tone. EXTA dials the hakama number "6" and counts the IC river trowel "6" in the same manner as described above. When the dial is finished and the C relay returns to slow speed, the ICO output goes to S6 of the ICI, S6 - D5 - terminal c - terminal d - D12 - IC

Perform the above-mentioned extension interconnection and connect the same machine to EXTA-l.
Create a connection path for OT-■-EXTS. At this time, the A code is S6-D5. In the path of one terminal c gradient terminal d-mc7, S
If there was an output for 5, it would be the same as "5", and the B code would be "6" because the ICO count is shameful [21, Cout], and extension 5 would be called, and a special telephone number would be sent to that number. Contain it.

This can be done arbitrarily by making an order when setting the special number.
The above time chart is shown in time chart 2 in FIG. As explained above, by simply using a simple connection (strap connection), a connection using a special number dial can be converted to a general extension interconnection connection, and the connection can be made without increasing the number of trunks or relays. , it is possible to connect economical special reserve telephones, and since the outgoing line side of the call path switch is not used, there is no effect on the number of outgoing lines when two or more telephones with the same special number setting are installed, for example. This effect is extremely significant in a small-capacity automatic private branch exchange system that has a single-stage communication route switch.

It goes without saying that the present invention can be applied in exactly the same manner even when a paging trunk, etc., which can be accommodated on the extension telephone side of a call path switch, is connected by a samurai number.
