Abstract: PURPOSE:To offer a private branch exchange(PBX) capable of rationally securing a hand-free function even when an extension telephone set for hand-free is not used in a telephone exchange system. CONSTITUTION:The private branch exchange(PBX) 1 is characterized by having a hand-free trunk 9 including at least a pair of hand-free means. In addition, the PBX 1 is characterized by connecting the trunk 9 between plural extension telephone sets 3, 4 and the telephone line 2 and connecting the trunk 9 between plural telephone lines.

Abstract: PURPOSE:To facilitate the line wire transfer in a communication device and to improve the management function of the communication device. CONSTITUTION:When a user A intends to transfer a call from a user B to a user C using a communication terminal C, the user A calls the communication terminal C by means of a transfer means while holding a communication terminal B (indicated by a dot line in the figure) in order to temporarily relaying the communication with the user B, as shown in figure (b). Then the user A releases the holding state of the communication terminal B (user B) and enables the communication among three terminals in mixing mode, as shown in figure (c). And then a switchboard device A transmits a soundless signal to the communication terminal B which is the source of incoming call and the communication terminal C by means of a soundless signal generation means and enables the communication between the user B and the user C, as shown in figure (d).

Abstract: PURPOSE:To execute packet communication through the use of a D-channel by permitting a service access point identifier to fetch layer information of packet control procedure information and to transfer it to exchange means exchanging layer information of a packet control procedure. CONSTITUTION:The processing functions of a layer 1 and a layer 2 and the exchange means 3 and 5 where the service access point identifier fetches information on the layer 3 of packet control procedure information and information on the layer 3 of the packet control procedure is exchanged are provided for an ISDN central office interface part 8 or ISDN extension interface parts 6 and 7. Thus, a packet processing can be distributed in the ISDN central office interface part 6 or the ISDN extension interface parts 6 and 7 in accordance with service access point identifier information in the packet on the D-channel of ISDN and packet communication using the D-channel can be executed.

Abstract: PURPOSE:To prevent a result in which an opponent is made awaited from occurring by judging a state that a terminal designated by a sub address is set at an unresponsible state at the time of receiving a call setting message again by the time-out of a response awaiting timer for the sending of the call setting message at a network side. CONSTITUTION:When the call setting messages 151 and 152 are received in idling time, a processing is shifted to an incoming call processing when its own terminal is not designated, and regular control is completed. When the sub address is not addressed to its own, the content of an area 154 for substitution response flag in a RAM 150 is checked, and when no flag is set, a state is recovered to an idling state, then, is set at a standby state. When the substitution response flag is set, buffers 151 and 152 for call setting message in a RAM 150 are checked, and it is judged whether or not the same message exists. When no same message exists, the message is stored in the air buffers of the buffers 151 and 152, then, a timer 140 is started.

Abstract: PURPOSE:To easily execute operation relating to a line wire specification number by sending a line wire selection number of a PBX in stead of prescribed data prior to a following dialings only when a telephone network specification request is generated and the line wire is stored in the PBX. CONSTITUTION:In a line wire selecting state, prescribed key data is inputted as 1st dial data in an terminating number storing memory, and only when a telephone network specification request is generated and the line wire 2 is stored in the PBX 3, the line wire selection number of the PBX 3 is sent in stead of the prescribed data prior to the following dialings. Since it is unnecessary to distinguish dialing operation between the line wire 1 of the telephone network 6 and the line wire 2 through the PBX 3, the operation relating to the specification of the line wire can be easily executed.

Abstract: PURPOSE:To output both call tones from a single sounding body by notifying a call signal in consecutive/intermittent tones respectively in response to the normality/abnormality of a state detected by a power supply detecting means. CONSTITUTION:When the voltage of an equipment power supply 10 is discriminated to be normal by a power voltage detection circuit 12, the output of a call tone generating circuit 7 is inhibited by a photocoupler 8, a call signal is detected/waveform-shaped by diodes D1-D4, the result is given to a one-shot multivibrator 9 via a photocoupler 3, a melody generating circuit 11 outputs a continuous melody tone. Since the output of the melody generating circuit 11 is inhibited and the photocoupler 8 is not operated when the voltage of the equipment power supply 10 is discriminated to be faulty, the output inhibition of the call tone generating circuit 7 is released. When the call signal reaches a line terminal 1, the call tone generating circuit 7 generates an intermittent signal to inform it. Thus, the single sounding body applies different incoming tone notice.

Abstract: PURPOSE:To facilitate a test and to shorten a testing time, by storing a testing program to a main body. CONSTITUTION:When a power source is turned on while an operating button is depressed, a test function program stored to an ROM13 is activated and an ROM test is executed. When an accumulating result is coincident, an RAM test is executed. When there is no error in read data, an operator executes a dial from a communication equipment 20 and also executes connection between a communication equipment 21 and aline. Then, a testing system is activated and data reception is waited. On the other hand, when the specified button of an operating part 15 is depressed, the communication equipment 20 transmits the prescribed data to be stored. When there is no error in the data received by the communication equipment 21, the data are transmitted from the communication equipment 21 and the comparison of the receiving data is executed in the communication equipment 20. Then, the means of the testing system is ended.
