Abstract : Computer Sciences Corporation has summarized a discussion of factors which impinge on the selection of digital modulation rates. Attached to the summary are two other papers bearing on the problem. The first is a paper presented at the International Conference on Communications, session 12, June 14, 1971 in Montreal, Canada. The second is extracted from Report No. 405600-1-3, 2 January, 1969, prepared for the Defense Communications Agency under Contract No. DCA100-67-C-0016. The conclusions reached based on this document are: (1) The selection of rates is constrained not by technical limitations but by cost factors taken in the context of the overall network under consideration. (2) A significant aspect of rate selection for advanced digital communication networks is the ease of interface with DCA and other networks. (3) Long association with the problem leads to the recommendation that the most desirable rate selection would be that set forth in the DCA standards.
