协议综合使用了RTS/CTS短分组握手机制、忙音信号、功率控制和CDMA技术来提高网络性能。

The RTS/CTS handshake mechanism, busy tone and power control are integrated with CDMA to improve the network performance.

他们希望打电话时有人接而不是听到忙音信号。 他们不想要交互系统告诉他们"如果......请按1，如果......请按2"，他们不想要语音邮件。

They want to get through when they call, they dont want busy signals, they don't want interactive systems telling them to push one for this and two for that-they don't want voice mail.

双忙音多址接入（DBTMA）协议是采用RTS/CTS对话机制来预约信道，通过引入两个窄带带外忙音信号来避免分组间冲突，解决了隐藏终端和暴露终端问题。

The operation of Dual Busy Tone Multiple Access(DBTMA) is based on the RTS/CTS packet and two narrow bandwidth, outofband busy tones. The RTS/CTS dialogue is used to reserve the channel.
