A recording medium has a substrate and a first color developing layer, a heat insulating layer and a second color developing layer laminated on the substrate in this order. The first color developing layer develops a first color at a temperature not less than a first threshold value. The second color developing layer develops a second color that is different from the first color at a temperature not less than a second threshold value that is higher than the first threshold value. The heat insulating layer has a first heat insulating layer of a first heat conductivity and a second heat insulating layer of a second heat conductivity that is higher than the first heat conductivity, which are laminated in a second direction orthogonal to a first direction in which the first color developing layer, the heat insulating layer, and the second color developing layer are laminated on the substrate.

A group communications switching method is disclosed. The method includes the steps of: maintaining a voice call between a first subscriber terminal and a second subscriber terminal when it becomes necessary to perform group communications while the voice call is in progress; starting a group communications call by the first subscriber terminal so as to call at least a group communications member other than the first subscriber terminal and the second subscriber terminal; and disconnecting the voice call between the first subscriber terminal and the second subscriber terminal when the group communications call is established.

A communication apparatus and a congestion regulation control method which execute regulation control at the time of congestion, thereby improving communication quality. A congestion monitor monitors a congestion state, sets a congestion level and determines whether or not to perform regulation based on the congestion level. Traffic measuring unit measures the number of received signals as a traffic intensity. A traffic comparitor compares the traffic intensity with a preset traffic-regulation start traffic intensity when it is determined that regulation is to be performed. A regulation control means performs traffic regulation control when a comparison result shows that the traffic intensity is equal to or greater than the traffic-regulation start traffic intensity, and performs regulation control on a maintenance and operation process when the traffic intensity is smaller than the traffic-regulation start traffic intensity.

A method of preventing an error of a pointer process in an SDH radio device which receives an STM frame having a section overhead and a payload therein includes the steps of distributing a pointer to unused bytes or undefined bytes in the section overhead of the STM frame, the pointer indicating a start position of multiplex data in the payload of the STM frame, and transmitting the STM frame to the SDH radio device.

Method and device for avoiding error of pointer process in SDH radio communication

An SDH multiplex transmission system has a transmission terminal apparatus and a reception terminal apparatus that are connected to each other through channels of an N+1 redundant structure. The transmission terminal apparatus loads predetermined information that violates SDH standards into the overhead of an STM frame and transmits the same to a spare channel that is not currently used. The reception terminal apparatus monitors an STM frame received through the spare channel, and when the predetermined information in the overhead thereof satisfies a predetermined violation detection condition, determines that the spare channel is unused. The violation information is byte information such as H1, MS-REI, or STM-ID. As a result, the SDH multiplex transmission system has a simple structure to let the reception terminal apparatus correctly determine whether or not the spare channel is used.

Multiplex transmission system and apparatuses for same

Disclosed is a radio apparatus in a synchronous digital hierarchy (SDH) network in which a radio transmission line having a plurality of radio lines is installed between optical transmission lines each having a plurality of optical lines. The radio apparatus includes a plurality of channel boards, each of which is provided between an optical line and a radio line, for transmitting an optical signal received from the optical line to the radio line and transmitting a signal received from the radio line to the optical line, a setting unit, which is provided to be shared by each channel board, for attaching, per channel board, priority value to clock contained in each signal sent in via an optical line and a radio line, and for setting, per channel board, whether the clock of each priority value is to be outputted or not, and an equipment-clock decision unit for deciding a clock shared by the entire apparatus. Each channel board enters a clock, whose output has been designated by the setting unit, as well as the priority value and quality value of the clock, into the equipment-clock decision unit. On the basis of the quality value and priority value of each clock entered from each channel board, the equipment-clock decision unit decides the equipment clock and enters the equipment clock into each channel board.
