A large size display is transportable, being construed of multiple rigid segments containing light emitting diodes (LED's). The rigid segments are linked by hinges or cables so the display is flexible and can be rolled up for storage and transport. The display can be unrolled upward or downwards such as from a protective container, such as a canister or truss. The weight of the display on the linked hinges or the tensioned cables provides sufficient rigidity. Such cables, like a signal and power distribution bus, are connected to the rear of each rigid element. The display can be repaired by removing and replacing selected rigid segments from the front thereof.

A method and apparatus for effecting 1:1 or N:1 equipment protection switching in the line units of a voice-and-data access and transport network includes three sets of switches associated with the line units that can be selectively provisioned by the system operator into protect groups. In one embodiment, the switches are arranged and controlled within the protect groups by one or more dedicated microprocessors such that, upon the failure of a protected one of the line units in a protect group, the stream of traffic to an associated, protect one of the line units in the protect group is dropped, and the traffic stream to the failed line unit is switched over to the protect line unit for continued processing.
