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.
Cette invention se rapporte à des procédés et à un appareil qui sont destinés à permettre la commutation efficace de lignes en câbles entre des cartes de lignes défaillantes et des cartes de lignes de protection. Les cartes de lignes peuvent être agencées en de multiples groupes de protection et d'activation prenant en charge des fréquences de transmission à la fois montantes et descendantes. Un commutateur électromécanique et à circuit solide combiné est prévu pour permettre la réaffectation efficace de lignes en câbles en cartes de lignes.
