摘要： PURPOSE:To prevent a momentary break for channel switching accompanied with radio zone movement of a communicating mobile machine by eliminating the transmission delay time difference between a base station and an exchange station and the delay time difference in the exchange station. CONSTITUTION:When a mobile station 1 is moved from the radio zone of a base station 31, with which the mobile machine 1 is communicating, to that of a base station 32, a proper delay time is given to data and the radio communication pattern of the mobile machine, which are transferred from the base station, by an exchange station 4 to match a super-frame clock PHI, and they are operated in a logical operation circuit 16 and are transmitted to a terminal 2 of the other party. A proper delay time is given to data from this terminal 2 by each base station to match the super-frame phase, and it is transmitted to the radio section, and channel switching in the wired section between the base station and the exchange station is performed after the mobile machine 1 completes zone movement and switches a channel. Thus, a momentary break accompanied with radio zone movement of the mobile machine is prevented.

摘要： PURPOSE:To provide a monitoring circuit which can not only monitor a mu-l aw signal used usually as a call monitoring circuit to monitor the line during the calling in a digital mobile communication exchange but also monitor correctly even a calling signal to adopt a coding system except it. CONSTITUTION:In a monitoring circuit to monitor with a receiver 6 after a calling signal is fetched from the line during the calling and converted by a digital/analog converting circuit 5, a calling monitor adding circuit 7 is provided at the front step of the digital/analog converting circuit 5, and here, when the calling signal fetched from the line during the calling is not the mu-l aw signal, it is detected, and after converting to the mu-l aw signal, the signal is inputted to the digital/analog converting circuit 5.

摘要： PURPOSE:To enable a user to effectively use satellite communication facility, etc., and to use a satellite line by changing service specification arbitrarily by providing a service specification selection part, etc., at a satellite communication terminal, and a service specification checking part, etc., at a control station. CONSTITUTION:A service specification storage part 11 and the service specification selection part 12 are provided at the satellite communication terminal 1, and the selection part 12 is provided with a means to input the will of the user by the operation of the user. And selected service specification is transmitted to the control station 3 via a control line which passes a transmission/ reception control part 15, a transmission part 13, and a satellite 2. The service specification is received by a reception part 34 at the station 3, and the validity of the service specification is checked by the service specification checking part 36 and a service specification table storage part 37, and allocation control and connection are executed according to the selected service specification by a line allocation control part 32 and a switching control part 33. In such a way, it is possible for a user to effectively use the satellite communication facility and a wave, and to use the satellite line by changing the service specification arbitrarily according to will of the user.

摘要： PURPOSE:To attain efficient branching aud bundle connection only via one stage of switch by providing plural time division switches each using a memory, applying branch connection by one time division switch and branch connection by other time division switch. CONSTITUTION:Data on an incoming highway 1 is stored tentatively in 1st and 2nd data buffer memories 6, 10. An address control memory 9 supplies a read address of the 1st data buffer memory 6 and the write address of the 2nd data buffer memory 10. The branch connection from one to plural channels in the 1st data buffer memory 6 by an instruction of the address control memory 9 and the bundle connection from the plural channels to one channel is applied in the 2nd data buffer memory 10. The data from the 1st and 2nd data buffer memories 6, 10 is sent to an outgoing highway via a data selector circuit.

摘要： PURPOSE:To attain economical service using a TDMA equipment and over by demmand assign/pre-assign in common by providing a demmand assign controller between the DTMA equipment and a terminal equipment and applying the demmand assign connection within a range of a satellite line band subject to pre-assign connection. CONSTITUTION:As the pre-assign service constitution, each ground station 2 is added with a demmand assign controller 25 and a control station is added with a demmand assign line management equipment 16. Channels of a satellite line used in the demmand assign service are all set as pre-assign circuits used in common to the demmand assign controller 25. A communication request from a terminal equipment 3 is detected by a signal processing circuit 252 in the demmand assign controller 25 and informed to a demmand assign line managing equipment 16 via a control signal satellite line 51. The equipment 16 selects a line not in use out of the pre-assign lines set already for the demmand assign and assigns it.

摘要： PROBLEM TO BE SOLVED: To simply realize a test method of communication quality in a communication system having a radio communication block by using a device with a simple configuration. SOLUTION: At first, a test personnel sets a portable terminal equipment 1 and a voice terminal equipment 7 to be a speech state. Then a sound source device 10 is operated to sound a voice signal of a prescribed frequency from a speaker 11. The speaker 11 approaches a transmitter of the portable terminal equipment 1 to input a voice signal of a prescribed frequency to the portable terminal equipment 1. Furthermore, the test personnel inputs a voice signal outputted from the voice terminal equipment 7 to a hit detection recorder 8 to discriminate a hit based on an alarm tone or an alarm lamp ancillary to the hit detection recorder 8 and records number of times of hits. Furthermore, the test personnel observes the waveform of a monitor signal 8a outputted from the voice terminal equipment 7 on an oscilloscope 9.
