(New York), American Telephone and Telegraph Company, 1950. 8vo. In the original printed blue wrappers. In Volume XXIX, July, No. 3, 1950 of "The Bell System Technical Journal". A bit of minor marginal browning to extremities, otherwise fine and clean. Pp. 343-359. [Entire issue: Pp. 295-468]. First edition of Shannon's influential paper on how to construct a telephone exchange network. "The problem of designing a good rearrangeable network was (probably first) considered in a paper of C.

This means that completion of a new call or termination of an old call will not disturb the state of memory elements associated with any call in progress. [.] Shannon's separate memory condition is actually met by modern connecting networks [.]. (Benes, Vaclav Edward. Mathematical Theory of Connecting Networks and Telephone Traffic: 017, 1965, p. 119.)
