Hi all,

Can anyone point me towards the documents detailing the American NI1 and
NI2 ISDN protocols? If I need to buy them, thats no prob, but I'm having
trouble finding where the specs are laid down.

Many thanks.

Please reply by email to t...@caribsurf.com , as my ISP sees fit to expire
news articles after a mere 24 hours!!

Cheers,
Alan Mott

We need the NI1/NI2 specs as well. Could someone tell us where
we can obtain these either on the web or as a paper copy?

Please email to fens...@circular.de

Thanks,
Chris Fenstermaker

some specifications: SR-NWT-001937 NI1

Hope this helps,

If you just want to know the feature set of NI-1, NI-2, etc.,
you should get the following Bellcore Special Reports:

SR-1957 National ISDN-1
SR-2120 National ISDN-2
SR-2457 National ISDN-3
SR-3476 National ISDN 1995 and 1996
SR-3875 National ISDN 1995, 1996, and 1997

If you want to know protocol details, especially with respect to
building CPE equipment, then you should get the following:

SR-3887 National ISDN 1997 PRI CPE Guidelines
SR-3888 National ISDN 1997 BRI CPE Guidelines

Protocol details are also available in the specific ISDN TR or GR
which you can find in the reference section of all of the above
listed documents.
