[comp.protocols.iso] Compatibility of X.25

kalyanas@bugs.cis.udel.edu (Pramod Kalyanasundaram) (04/12/91)

	I am interested in knowing the major changes between the X.25
recommendations (1980) and the X.25 (1984) regarding the following :

	- LAP B 
	- the m, d , q bits
	- the Permanent Virtual Circuits (PVCs)

	Regarding the above, if there is an implementation of the 1980
version of X.25, can it be used to directly interface with an X.25 
implementation of X.25(1984)? If not, what are the things to look for?
Could any X.25 whiz out there, help me please? 
Please email your responses to me at the address given below.
Thanks in anticipation of an early response

	group I should post this article on. So, I am posting it on
	comp.protocols.misc and comp.protocols.iso. Experienced net users
	please don't flame me for wasting b/w.
