摘要: An downstream external Physical Layer (PHY) interface between a network and an edge quadrature amplitude modulator (EQAM) is provided. The comprises, input direct memory access (DMA) controller enabled to control rate of packets received from the network, plurality buffers store packets, first module convert format second format. further comprises processors customize output based on instructions stored in instruction flow meters determine for on, at least part, EQAM. DMA controls egress
