摘要： PURPOSE:To execute the economic communication in accordance with the communicating quality by discriminating the communicating quality from the signal transmitted from a facsimile terminal to a digital network and changing a digital communicating speed based on the discriminating result. CONSTITUTION:An FAX 10 is connected through an LAN 30 and an MODEM 4a to a network control device NCU, an automatic oscillating part, an MODEM and an FAX 2. When the FAX 10 is at the transmitting side, a response signal is generated from the FAX 2 after the FAX 10 and the FAX 2 are connected to the line. By the response signal, the FAX 10 sends a training signal. The FAX 2 checks a training and outputs the result. The FAX 10 identifies whether a training checking signal is good or bad. Here, when it is identified to be bad, the communicating speed is lowered and the communication is executed. The communication can be executed in accordance with the line quality of the FAX.

摘要： PURPOSE:To attain efficient simultaneous operation of a facsimile equipment and a telephone set connected to one subscriber line by inserting an AC call signal between DC call signals to a reception side at the network side so as to allow the reception side facsimile equipment automatically to identify a call from a telephone set and a call of a facsimile equipment. CONSTITUTION:A reception side exchange 220 of a communication network 200 has a 2-way call signal generating section 223 and an AC call signal 1100Hz is generated between DC call signals 16Hz by the request of a sender side. Moreover, an NCU 340 of a receiver side facsimile equipment 300 is provided with a DC call signal detection section IRDET 341 detecting both the call signals respectively and an AC call signal detection section CNGDET 342. A changeover section 344 consists of a switch 3441 and a 2-4 wire conversion section 3442 and when only the DC call signal is detected by the IRDET 341 and the CNGDET342, the switch 3441 connects a line to a telephone set 330 by using s control signal from a control section CTL 343. Furthermore, when both the call signals are detected, the switch 3441 connects the line to a FAX main body 310 via the 2-4 line conversion section 3442.

摘要： PURPOSE: To attain communication between a facsimile equipment accommodated in a facsimile communication network and a mobile body facsimile equipment or between the mobile facsimile equipments even if a facsimile equipment is parted from a specific service area by providing a communication function between a facsimile communication network and a mobile communication network and providing a mobile communication function to the facsimile equipment.
CONSTITUTION: A mobile facsimile equipment 125a (132a) might be moved during communication. Thus, the mobile communication network 137 supervises quality of a communication line (radio) even during communication and when deteriorated quality is detected, a channel number and quality supervisory request are transmitted to a surrounding adjacent radio terminal station 123a (133a) via a radio line control station 124 (134). The mobile communication network 137 designates an idle control channel by using a control channel to the mobile facsimile equipment 125a (135a) and controls the channel switching during communication. Thus, the mobile facsimile equipment 125a (135a) transmits/receives a facsimile picture continuously even in a different service area through the designated new communication channel.

摘要： PURPOSE:To achieve the bracketing of a fault position by testing a circuit side and an exchange side independently by switching a trunk circuit package and a testing device. CONSTITUTION:To the package position 7 of a trunk package to be tested, a testing device 6 having a circuit-side testing terminal T0 and an exchange-side test terminal T1 is connected. A call line from the exchange-side test terminal T1 is connected to a signal transmitting and receiving means 1, and a control line to a controller 3. Consequently, the circuit side and exchange side are tested independently of each other. The operation characteristics of a trunk circuit to be tested are confirmed by testing the trunk circuit to be tested. Thus, a fault point is discriminated easily for the test of the operation characteristics of an exchange system.

摘要： PURPOSE:To recognize that an operator call is executed at the transmitting side by sending a sound in the calling to a transmission side at a reception side when a call signal is transmitted from the transmission side at the time of the condition in which the line of the image communication executed by the telephone reservation is connected. CONSTITUTION:A call signal transmitted from a transmission side based on a telephone reservation is detected by a call signal detecting circuit 19b at the reception side. For a detecting circuit 19b, a detecting signal is sent to a calling tone generating circuit 21a and a transmission tone control circuit 23b. The calling tone generating circuit 21a originates an operator call signal and rings a speaker 22. The transmission tone control circuit 23b commands to a transmission tone generating circuit 23a and generates a ringback tone. A gate circuit 24 is switched, and a ringback tone is transmitted through a two-wire/four-wire converting circuit 19 to a transmission side by the line. At the transmission side, it is recognized by a ringback tone that the operator call is executed. Thus, it can be confirmed that the equipment is normally operated.

摘要： PURPOSE:To reduce the transmission time by sending plural lines of picture information while being multiplexed and demultiplexing the information at the receiving side so as to reduce the quantity of sent information. CONSTITUTION:A line synthesis means 111 synthesizes plural lines of introduced picture information into a one-line data and a transmission means 141 sends the synthesized data by the means 111 under the control of a transmission control means 131. A reception means 161 receives the data sent from the means 141 by the control of a reception control means 171 and uses a line demultiplex means 191 to demultiplex the data into plural lines of picture information. Thus, the quantity of transmitted information is decreased in this way to reduce the transmission time.

摘要： PURPOSE:To prevent the deterioration in the ratio of a signal to noise (S/N) resulting from the return power of a transmission path by varying and controlling the transmission level of a picture information signal according to the transmission remote destination of original information. CONSTITUTION:A selection signal and a level constant are read and registered in a register A and the read level constant is registered in a register B 383. Based on the level constant registered in the register B 383, a level adjusting circuit 251 is driven, an attenuator 369 is changed over and selected by a selection circuit 365 and a selection circuit 367 and the transmission level is varied and set. Thereby, the suitable transmission level to a transmission characteristic in a route passing through a line 61, an exchange or the like can be determined, so that a high quality in transmitting the information in the transmission path is obtained.
