Abstract: A miniMAC implementation of a distributed CMTS in a hybrid fiber/coaxial (HFC) plant. The distributed CMTS comprises at least one network layer, at least one media access layer, and one or more physical layers. The at least one media access layer includes one or more miniMAC layers. The one or more miniMAC layers are remotely located from a remaining part of the at least one media access layer. The at least one network layer, the remaining part of the at least one media access layer, the one or more miniMAC layers, and the one or more physical layers each function as separate modules, enabling each layer to be in separate component locations of the HFC plant, yet having the at least one network layer connected to the remaining part of the at least one media access layer, the at least one media access layer connected to each of the one or more miniMAC layers, and each of the one or more physical layers connected to each of the one or more miniMAC layers. The one or more miniMAC layers are located in close proximity to the one or more physical layers in the HFC plant. The one or more miniMAC layers convert digital bit streams into packets and maintain timing constraints between the one or more miniMAC layers and the one or more physical layers.

Abstract translation: 在混合光纤/同轴（HFC）设备中的分布式CMTS的miniMAC实现。 分布式CMTS包括至少一个网络层，至少一个媒体访问层以及一个或多个物理层。 所述至少一个媒体接入层包括一个或多个miniMAC层。 所述一个或多个miniMAC层远离所述至少一个媒体接入层的剩余部分。 所述至少一个网络层，所述至少一个媒体访问层的剩余部分，所述一个或多个miniMAC层以及所述一个或多个物理层各自用作单独的模块，使得每个层能够处于 HFC工厂，但是具有至少一个网络层连接到所述至少一个媒体接入层的剩余部分，所述至少一个媒体接入层连接到所述一个或多个miniMAC层中的每一个，并且所述一个或多个 物理层连接到一个或多个miniMAC层中的每一个。 一个或多个miniMAC层位于HFC工厂中的一个或多个物理层附近。 一个或多个miniMAC层将数字比特流转换成分组，并在一个或多个miniMAC层与一个或多个物理层之间维持时序约束。
