摘要： A number of features for enhancing the performance of a communication system, in which data is transmitted between a base station and a plurality of subscriber stations located different distances from the base station, are presented. The power transmission level, slot timing, and equalization of the subscriber stations are set by a ranging process. Data is transmitted by the subscriber stations in fragmented form. Various measures are taken to make transmission from the subscriber stations robust. The uplink data transmission is controlled to permit multiple access from the subscriber stations.

摘要： A plurality of CMTS devices are linked together and synchronized to facilitate communication between the respective CMTS devices and respective downstream cable modems. According to one embodiment of the invention, one of the CMTS devices is designated as a master device, and the other CMTS devices are designated as slave devices. The respective CMTS devices are connected to each other by means of a synchronization bus. The master CMTS device then generates and broadcasts a future time stamp value, which is received by the respective slave CMTS devices. When the time stamp counter in the master CMTS device reaches the transmitted value, a control signal is broadcast over the synchronization bus. The slave CMTS devices then retrieve the time stamp value and reset their respective local time stamp counters to the received value. In this manner, the CMTS devices are synchronized.

摘要： Upstream requests such a bandwidth requests, are processed by CMTS out of order on a priority basis to reduce latency in responding to the request. Specifically, a cable modem termination system (CMTS) is connected to a plurality of cable modems by a cable plant. The CMTS has a burst receiver adapted to be connected to the cable plant to process upstream data packet units and bandwidth requests transmitted by the cable modems. Each packet includes a header that uniquely distinguishes the bandwidth requests from other data types. Packet data units are arranged in a first memory queue. Bandwidth requests are arranged in a second memory queue. The headers of the packets processed by the burst receiver are inspected as they arrive at the CMTS to determine if the packets are packet data units or bandwidth requests. Packet data units are routed to the first memory queue. Bandwidth requests are routed to the second memory queue. Bandwidth allocation MAP messages are generated from the bandwidth requests stored in the second queue and transmitted downstream to the cable modems. The packet data units stored in the first queue are coupled to a data output for further distribution.
摘要翻译： 上行请求这样的带宽请求由CMTS按优先级顺序处理，以减少响应请求的延迟。 具体来说，电缆调制解调器终端系统（CMTS）由电缆设备连接到多个电缆调制解调器。 CMTS具有适于连接到电缆设备的突发接收器，以处理由电缆调制解调器发送的上行数据分组单元和带宽请求。 每个数据包包括一个能够唯一区分带宽请求与其他数据类型的头。 分组数据单元被布置在第一存储器队列中。 带宽请求被排列在第二个存储器队列中。 由突发接收器处理的分组的报头在到达CMTS时进行检查，以确定分组是分组数据单元还是带宽请求。 分组数据单元被路由到第一个存储器队列。 带宽请求被路由到第二个内存队列。 带宽分配MAP消息是从存储在第二个队列中的带宽请求产生的，并向下游发送到电缆调制解调器。 存储在第一队列中的分组数据单元被耦合到数据输出用于进一步分配。

摘要： In a wireless communication system, the time required to establish network connectivity for subscriber stations can be reduced by prioritizing and/or reducing contention between the subscriber stations. The subscriber stations can be divided into acquisition groups and assigned specific uplink channels on which to range. The subscriber stations can randomly or pseudo-randomly range on uplink channels.
