摘要： A loop carrier system includes a home local area network having plural telephone modules and a hub coupled to in-home telephone wiring. The telephone modules and the hub communicate voice signals over the in-home wiring in a dedicated frequency band above baseband POTS. The hub converts between voice signals and voice packets and is connected to a network access device for transferring the voice packets from the home local area network to a telecommunications network which routes the voice packets to a gateway. The gateway converts between the voice packets and a circuit format compatible with a local digital voice switch.
摘要翻译：环路载波系统包括具有多个电话模块的家庭局域网和耦合到家庭内电话线路的集线器。电话模块和集线器在基带POTS之上的专用频带内通过家庭内线路传送语音信号。集线器在语音信号和语音分组之间进行转换，并连接到网络接入设备，用于将语音分组从本地局域网传送到将语音分组路由到网关的电信网络。网关在语音数据包和与本地数字语音交换机兼容的电路格式之间进行转换。

The gateway converts between the voice packets and a circuit format compatible with a local digital voice switch. The home local area network includes a timing recovery mechanism which in the absence of a clock that is traceable to the Primary Reference Clock on the public network is robust to clock drift, cell delay variation and cell impairments.

摘要： In one embodiment, a flow control module aggregates indications of queuing resource utilization at devices attached to a switching fabric within a router and broadcasts that information out of band to all devices attached to the same switching fabric. When the flow control module identifies congestion at one of the attached devices according to the indications, the module may also cause a throttling of traffic sent to the congested device in addition to sending the out of band indication of the congestion to all the attached devices. Flow control modules for each of the attached devices provide local interrupts for reducing outbound traffic to a congested device according to the identification of that remote congestion.
摘要翻译：在一个实施例中，流控制模块聚集在连接到路由器内的交换结构的设备处的排队资源利用的指示，并将该信息带外广播到连接到同一交换结构的所有设备。当流控制模块根据指示识别附加设备之一的拥塞时，除了向所有连接的设备发送拥塞的带外指示之外，模块还可能导致发送到拥塞设备的业务的节流。每个连接设备的流量控制模块根据该远程拥塞的识别提供本地中断，以减少到拥塞设备的出站流量。
