26 Feb 1981TL;DR: In this article, a line protocol format with a variable bit rate and low bit overhead provides for the high integrity, synchronous exchange of digital signal information between master and slave processing units, with master processing unit controlling the line protocol.
Abstract: In a communication system, a line protocol format with a variable bit rate and low bit overhead provides for the high integrity, synchronous exchange of digital signal information between master and slave processing units, with master processing unit controlling the line protocol.

TL;DR: The notion of mutual encapsulation is explored; as an example, the coexistence of the Xerox internet environment with the Arpa internet environment is considered; each of these systems is composed of several individual networks with a variety of protocols and performance parameters; but with Mutual encapsulation each can make use of the capabilities of the other.

TL;DR: General aspects of communication protocol analysis, protocol analysis technologies for CCITT X, and the protocol analyzer to be used in DDX packet switched network operation are described.
Abstract: Communication failures may occur because of residual hardware or software implementation flaws, operator errors, transmission noises and transient or permanent machine failures. For packet switched network operation, some means are necessary to detect the errors and to analyze the phenomena to identify the causes of the errors, since, generally, it is almost impossible to predict errors or to implement systems without errors or failures. This paper describes general aspects of communication protocol analysis, protocol analysis technologies for CCITT X.25 and the protocol analyzer to be used in DDX packet switched network operation.
