摘要： When a signal is transmitted from an STM line to an ATM relay channel, the signal is compressed to be cell assembled into a cell. To the contrary, a signal from the ATM relay channel is cell disassembled into separate data and then expanded. In cases where signals are exchanged between ATM relay channels, a multistage relay device does not repeatedly execute signal compression/expansion to the signal. Switching for the above operations is achieved, utilizing a signal pattern inserted into audio data. With this arrangement, an audio one-link operation is established in the environment where an STM and an ATM coexist. Because compression/expansion processes are not repeatedly conducted, delay in relaying is avoided.
摘要翻译：当信号从STM线路发送到ATM中继信道时，该信号被压缩以将其细胞组装到一个单元中。相反，来自ATM中继信道的信号被细分为单独的数据，然后被扩展。在信号在ATM中继信道之间交换的情况下，多级中继装置不会对信号重复执行信号压缩/扩展。利用插入到音频数据中的信号模式，实现上述操作的切换。利用这种布置，在STM和ATM共存的环境中建立音频单链接操作。由于不重复进行压缩/扩展处理，所以避免了中继的延迟。

摘要： In establishing an audio one link connection wherein an audio signal is not encoded/decoded in a relay station, loud noises may be produced if the states of two audio tandem relay devices which make a pair during relay are changed from a normal connection state to a relay connection state at different times. In order to solve this problem, comfort noise generators are provided. In detail, when a first pattern signal is detected while a relay call is connected via a relay exchange, switches are switched to be connected at a contact point 1, and a switch is at a contact point 2. Upon detection of a second pattern signal, the switches are connected at the contact points 2, while the switches are connected at the contact points 2. With this arrangement, outputs from the comfort noise generators are selected and outputted during a period from first pattern signal detection to second pattern signal detection, during which the states of the two devices of a pair are different. As a result, occurrence of loud noises is prevented.

摘要： A timing master device transmits a timing packet for synchronizing time of base stations at each cycle of preset time synchronization adjustment timing. The base stations adjust a local-station standard timer based on the timing packet. The base stations measure a delay time of a network form the timing master device to a local station, and adjust the local-station standard timer based on the measured delay time.

摘要： A control unit (100) sets up a path in a protocol conversion apparatus (30) based on call setting information from the calling side terminal. A signal monitor unit (300) monitors main data 220a transmitted in the path and sent/received between the terminals. When a specific connectivity confirmation sequence is detected by the signal monitor unit (300), the result is forwarded to the control unit (100). Based on the forwarded result, the control unit (100) specifies a protocol of the calling side terminal and a protocol of the called side terminal. A protocol conversion unit (310) performs the most suitable protocol conversion based on the specified protocols.
