Existing transmission procedures have been devised to control transmission over wire-like channels, since it was the only widely available medium, usually telephone lines. New proposals discussed in ECMA or ISO are somehow ambiguous, as they give no hint as to which transmission medium is assumed. In fact, the proposed schemes assume a wire-like medium, although this is not mentioned. New technologies, such as satellite links, or packet switching, present somewhat different characteristics, which are not taken into account in the present proposals for standardization. Since these technologies are on the verge of commercial applications, it seems desirable to investigate whether their specific requirements can be reasonably met by future standards. If it were not, then other standards would become necessary. On the other hand, it seems that procedures applicable to packet switching networks links are also satisfactory when used over wirelike links. Then it would make sense not to miss the opportunity to work out a single set of standards. The present paper examines some characteristics of new transmission technologies, and puts forth some proposals.
