摘要：
A system and method for the simultaneous transmission of point-to-point and broadcast signals over an optical network are provided. In accordance with this invention, the user terminals of the system are divided into groups of user terminals, each assigned a different waveband. Each user terminal within one group is assigned a different point-to-point code within its corresponding waveband for encoding and decoding point-to-point signals exchanged with the central office. A signal broadcast code is assigned per groups of users and therefore per wavebands, for all of the users of a same group to use. All signals on all wavebands are transmitted through the network, but each user terminal may only access point-to-point signals addressed to himself and a copy of the broadcast signal.
摘要（中）：
提供了一种用于通过光网络同时传输点对点和广播信号的系统和方法。 根据本发明，系统的用户终端被分成用户终端组，每个用户终端分配不同的波段。 在一组内的每个用户终端在其对应的波段内分配不同的点对点码，用于对与中心局交换的点对点信号进行编码和解码。 每组用户分配信号广播代码，因此每个波段分配给同一组的所有用户使用。 所有波段上的所有信号都通过网络传输，但每个用户终端只能访问寻址到自己的点对点信号和广播信号的副本。
