Abstract:

Work continued on the refinement of user needs and the coordination of solutions for problems extending over more than one subsystem. The need for a register recall feature was defined and user evaluation tests of the UNICOM user control set have been initiated. A study is completed on system implications of degraded transmission conditions. In the Network Planning area, an initial plan is complete for system control, which is organized in a distributed manner with each switching center making decisions based on information about the entire network. A digital-computer program simulating the system control process in a network of switching centers is complete debugging and initial testing are underway. Simulations are complete for alternate routing of direct and indirect traffic, use of automatic retrial for direct traffic, and use of trunk reservation for high-precedence traffic. In Switching and Signaling areas, switching requirements are prepared. Author
