Abstract
A digital communication network (10) with a multiple space storage, time space-time configuration defined by a first, or input, time stage (12), a second, or output, time stage (14) and a preselected number of space stages (16, 22, 24) interconnected between the time stages 12, 14) that introduce time delays which are compensated for by means for time shifting the data in a shadow memory (32) relative to data in a regular memory (34). On-line expansion is accomplished by operating the network (10) off of one of the regular memory and the shadow memory (32) during the expansion, introducing the amount of compensation required by the expansion and then shifting operation over to the other memory. The selection between memories (34, 32) is achieved by means of a trislatable device (38).
