Abstract
In a telecommunications switching system having an "all time" network, the network is divided into a plurality of blocks, each of the blocks having assigned thereto dedicated groups of access ports for completing connections between those ports and any of the other ports in the system. A single spare network block is provided having a programmable identity and capable of functioning in the place of any of the primary blocks. In the event of a malfunction in a primary block, the spare network block is assigned the identity of the primary block, is enabled, the faulty block disabled, and call processing continues just as if the primary block were on line.
