SWITCHING CENTER SIZE
The number of communication lines to be connected to the DATANET-30 permits a broad defini-
tion for the size of a switching center and associated equipment. A switching center can be defined
as small, medium or large.
Small Switching Center
A small switching center would have an RDC 930 Removable Disc Unit and up to 10 communica-
tion lines of half duplex or full duplex operation. The amount of traffic is assumed to be in the
range of 1 million characters per day throughput. The RDC 930 Removable Disc Unit is especially
adaptable to this size system.
