Abstract: A computer implemented method for generating a test plan for a communication device under test. The test plan defines test tools, test methodologies, test configurations, and algorithms for executing the test. A user input is received to define the communication device under test. Next, a knowledge database is searched to identify test plan parameters for the communication device under test. Thereafter, the test plan parameters and the user input are analyzed to identify the test plan. A system and computer readable medium having program instructions for generating a test plan for a communication device under test are also described.

Abstract: Timestamp information can be placed in a frame that includes a first portion processable at a selected layer of a protocol stack and a second portion processable at a lower protocol layer of the protocol stack subsequently to the processing of the first portion, wherein the first portion is contained within the second portion and wherein a numerically computed error detection code for the second portion is computed during processing of the second portion. A timestamp signature having a timestamp subfield of initialized data and a corrector subfield of initialized data is embedded in the first portion during processing thereof at the selected protocol layer. A numerical constant functionally equivalent to the numerically computed error detection code is determinable from the initialized data in the timestamp subfield and the corrector subfield. The data in said timestamp subfield is modified with timestamp information subsequently to processing of the second portion at the lower protocol layer.
