It is exchanged through 14.

The operation of the automatic transfer information notification system shown in FIG. 1 will be described with reference to the control flow chart of the control device of the private branch exchange shown in FIG. Extension telephone A with extension number 200
13-1 dials the extension number 201 and makes a call to the extension telephone B 13-2.
-1 through the information distribution device 14 and dial number "20"
1 "is transmitted to the control device 15 and" extension telephone A 13
The connection control unit 150 is activated with the information that "-1 is outgoing" (step S1). "Extension telephone A 13-1"
The connection control unit 150, which has received the information “call originating” and “dial 201”, refers to the extension state memory 154, and thereby the extension telephone B 1 having the extension number 201.
The state of 3-2 is determined (step S2). The extension state memory 154 stores the state of the extension. The status includes "absent", "busy", "call rejection", "empty", and the like. If the status matches the transfer type identifier, it is determined that "there is a state for performing automatic transfer", and the status is determined. If not, it is determined that "there is no state for performing automatic transfer". If there is no state for automatic transfer, the extension telephone B 13-
2 is subjected to incoming call control (step S13). Extension B
If 13-2 has not responded for a certain period of time, the extension number of the non-responding transfer destination is read from the automatic transfer information memory 151 (step S14), and it is determined whether or not there is an extension number of the transfer destination (step S14). Step S6). If there is a state in which automatic transfer is performed, the extension number of the transfer destination suitable for the current state (absence, busy, or call rejection) is read from the automatic transfer information memory 151 (steps S3, S4, and S4).
5) It is determined whether there is an extension number of the transfer destination (step S6). If there is no extension number of the transfer destination (NO in step S6), incoming call control is performed on the extension telephone B 13-2 (step S13). If there is an extension number of the transfer destination (YES in step S6), it is determined whether or not the extension number of the transfer destination is stored in the PHS extension number memory 153, so that the extension number of the transfer destination is a private PHS. It is determined whether the extension number is 300 of the terminal 10 (step S7). The extension number of the transfer destination is a private company PH
If the extension number is not the extension number 300 of the S terminal 100 (NO in step S7), incoming call control is immediately performed on the transfer destination of the extension number (step S12). When the extension number of the transfer destination is the extension number 300 of the private PHS terminal 100 (YES in step S7), the number of the transfer type is converted into a character string of the transfer type using the conversion table 152 (step S8). The converted character string and the extension number “201” of the extension telephone B 13-2 as the transfer source and the extension number “200” of the extension telephone A 13-1 as the transmission source are RCRST.
The display information element defined by the D-28 standard is set (step S9), and the display information element after the setting is set to RCR S
In addition to the call setup message defined by the TD-28 standard, the call setup message is transmitted to the PHS base station 11 via the information distribution device 14 (step S10). Thereafter, in accordance with the RCR STD-28 standard, a terminating connection is performed according to a standardized protocol model, and the private PHS terminal 10 is called (step S11).

For example, when the state of the extension telephone B 13-2 is busy, the area of the automatic transfer information memory 151 having the extension number 201 and the transfer type 2 is read (step S4). Since the extension number 300 is stored in that area (YES in step S6), it is determined whether or not the extension number is the extension number of the private PHS terminal (step S7). In this case, since the transfer destination is the PHS terminal for private use (YES in step S7), the transfer destination is converted into a character string of "Wachu Tensou" which is a character string of the transfer type corresponding to the transfer type number 2 using the conversion table 152 ( Step S8). Character string after conversion and source extension number “20”
1 "and the caller's extension number" 200 "are set as display information elements (step S9), the display information element after the setting is added to the call setting message, and the added call setting message is stored in the PH.
It transmits to S base station 11 (step S10). next,
Incoming call control is performed, and the PHS terminal 10 is called (step S11).
