ABSTRACT:
A scanner-distributor for large electronic space-division exchanges is provided to operate from a logic address to scan a plurality of points in a number of junctors. A converter translates the logic address into a 1-out-of-x code and is followed by a distribution frame which translates the 1-out-of-x code address into a physical address. Thus, growth is possible in the exchange without disturbing the sequence of logic addresses, since new junctors may be coupled in the distribution frame without requiring that changes be made in either the prior existing logic addresses or the prior wiring in the distribution frame.
