Cisco uBR7246VXR Universal Broadband Router Configurations

A single Cisco uBR7246VXR router contains up to four Cisco uBR-MC16x (C, E, S, U, or X) line cards or Cisco uBR-MC28x(C, U, or X) line cards. This configuration uses a redundancy scheme where one protect card supports from one to four working line cards.

Note The Cisco uBR-MC16U cable interface line cards have onboard upconverters. Upconverters are not required in a configuration using this line card.
