In the tree-and-branch architecture, how is the downstream signal from the trunk fed to the distribution branches? Within each trunk amplifier, a portion of the downstream is fed to a bridger amplifier to boost the signal before being split and routed to the distribution branches. What is a common solution when congestion from modem activity and traffic becomes unacceptable in a hybrid fiber/coax (HFC) network? Node splitting, the subdividing of serving areas into two or more smaller servin...
