由控制信道来动态分配信道，空中信令采用MSK调制的数字共路信令，具有接续速度快的特点。
Channels are dynamically distributed using the control signaling. MSK modulated digital common signal is used as air signal, characterized by its fast connecting.
详细论述多频互控方式的信令信号传送，交换机DTMF信令无线信道接续与控制。
We study the transmission of signaling signal with the compelled method of multi-frequency, and study the switching control of DTMF signaling with exchange in wireless in details.
终端信息消息不仅包括来自接收端的通信方式优先级、逻辑信道信令、控制与指示，而且也包括接收和传输能力。
The messages cover receiving and transmitting capabilities as well as mode preference from the receiving end, logical channel signalling, and Control and Indication.
