Abstract
An apparatus for interconnecting a fiber-optic network and a coax network comprising a coax line terminal (CLT) configured to couple to an optical line terminal (OLT) at the fiber-optic network and a plurality of coax network units (CNUs) at the coax network and to cache data received from the CNUs and forward the cached data to the OLT upon receiving a message from the OLT that assigns a transmission cycle for a specified CNU, wherein the CLT forwards the cached data to the OLT upon receiving the message regardless of whether the cached data corresponds to the specified CNU.
