ABSTRACT:
According to the present invention, methods and apparatus are provided to allow efficient switching of cable lines from failed line cards to protect line cards. Line cards may be arranged in multiple protect and active groups supporting both upstream and downstream transmission frequencies. A combined electromechanical and solid state switching fabric is provided to efficiently allow reassignment of cable lines to line cards.
