This Recommendation describes all the point-to-point procedures involving the BAS codes: initial capability exchange and mode initialization, including restricted-network operation; 本建议描述所有的包括BAS码的点对点规程:初始能力交换和模式初始化,包括受限网络操作;
While DWDM has been traditionally used just to increase the transport capacity in point-to-point networks, which leads the networks to weak scalability, expensive cost, complex operation and low efficiency. 传统DWDM技术只是应用于点到点网络中来增加带宽容量,这样的网络缺乏可伸缩性,费用昂贵,操作复杂且效率较低。
Compared with traditional point-to-point control systems, networked control systems have many advantages, such as low installation cost, ease of diagnosis and maintenance, and flexibility of operation and so on. 相对于传统的点对点直接连接的控制系统而言,网络化控制系统有许多优点。例如,系统的安装费用低廉,系统的维护比较容易以及系统的操作也相对简单等。
