报告了一种新的、使数据信号能在混合光纤／同轴信道上有效传输的煤质接入协议。这一工作的目的是保证协议中有关终端的部分尽可能简单。因此，在有线电视前端采用集中式控制。想要发送信号的终端站利用争用信道向前端发送一个申请，前端应答这个申请，对申请进行排队，并确切地通知终端何时可以发送信息。研究表明，这个协议在各种情况下都是有效的，并且，其信道噪声具有鲁棒性。
Reported a new coal quality access protocol that enables data signals to be efficiently transmitted over a hybrid fiber / coax channel. The purpose of this work is to ensure that the terminal part of the agreement is as simple as possible. Therefore, centralized control is used at the cable TV front end. The terminal station that wants to send a signal uses the contention channel to send an application to the headend. The headend replies to this application, queues the application, and informs exactly when the terminal can send the message. Research shows that this protocol is effective in all cases and its channel noise is robust.
