As far as I know the VN4 is not yet Euro ISDN. Hence the reason for the deltas, which as Nick says have now been withdrawn as a regulatory requirement. It was withdrawn as a result of pressure from the commission and not because of a change of the network. The deltas CSE P-1020A & CSE P-1021A still exist as voluntary standards. I do know that Euro ISDN products will work on VN4 but not on VN3 services. VN3 products will work on VN3 or VN4. In France you can still order VN3 or VN4. I think.

Therefore CE X marked products can be used.From what I was told a while ago the VN4 is the French Euro Numeres service which is Euro ISDNVN3 is the original French ISDN with regards to the % of the installed base I do not know.Nic Hughes----- Previous Message ---------------------------------------------------- To: treg @ world.std.com @ UGATEcc: From: jdc @ world.std.com (Jon D Curtis) @ UGATE Date: Wednesday October 16, 1996 03:20Subject: BOUNCE [email protected]: Non-member submission from [[email protected]] (fwd)----------------------------------------------------------------------- ---------------------------------------------------------------------------- -------------------------------------------From: [email protected] TREGers, I would like to understand BRI approval requirements and switch designations in France. We have gained European approvals on a BRI product in the past, but I suspect things have changed since then, thus would like the latest. Any answers to the following questions, as well as any other information that may be useful would be appreciated. - How common are VN3 switches? VN4? (i.e. 60/40%) - Is VN4 equivalent to I-CTR3 - Euro ISDN? If not, what is the French designation for Euro ISDN? - Is VN3+ an interim between VN3 and VN4, or another name for VN4? (or neither?) - Can Euro ISDN (CEX) approval be used in France without delta testing? (realizing the product is only certified for use on Euro ISDN networks) Thanks in advance for your responses, Barry Marks, Sr. Regulatory Engineer, VTEL Corp.
