1·They can be used in point-to-point subinterface configuration or point-to-multipoint nonbroadcast multiaccess (NBMA) configuration.
它们可用于点对点子接口配置或点对多点非广播多址配置。
2·In this paper, the principle of ultra-wideband multiaccess communication is analyzed with the transmitting signal.
该文首先分析了超宽带发射信号实现多址通信的原理。
3·Once an SVC is established, it functions like a PVC. SVCs can be used in point-to-point subinterface configuration or point-to-multipoint nonbroadcast multiaccess (NBMA) configuration.
一旦建立了SVC，它就像一个PVC一样的工作。SVC可被用于点对点子界面配置或点对多点非广播多路访问（NBMA）配置中。
4·The concept, function and architecture of passive optical network (PON) are presented in this paper. The multiplexing and multiaccess transmission technologies for PON are also described.
本文介绍了无源光网络(PON)的基本概念、功能、结构以及其多路复用与多址技术。
