Here are two follow-ups on the E.164 and NP presentations to the enum 
     wg session last week in Pittsburgh.  They are:
     
     - Brief history of E.164 publication, and
     - Q-series recs/supps on NP from SG11.
     
     1.  Brief history of E.164 publication (based on information in the 
     current version, the fourth issue, dated 05/97):
     
     -  Rec E.163, first issue 1964.
     -  Rec E.164, revised at all subsequent Plenary Assemblies.
     -  Rec E.163, merged with Recommendation E.164 in 1991.
     
     -  Rec E.164, first issue 1984, in a Red Book fascicle.
     -  Rec E.164, second issue 1988, in a Blue Book fascicle.
     -  Rec E.164, third issue 1991, as an individual document,
                    and merged with Recommendation E.163.
     -  Rec E.164, fourth issue 1997, incorporates Recs E.160 and E.162.
     
     In 1997, Rec. E.164 itself did not contain the list of E.164 country 
     codes.  That list is maintained separately as an Annex to the series 
     of Operational Bulletins.
     
     2.  There are two recommendations and three supplements in the 
     Q-series from SG11.  The five documents are:
     
     -  Rec. Q.769.1 (12/99), "Signalling System No. 7 - ISDN user part 
         enhancements for the support of number portability", 24 pages.
     -  Rec. Q.2769.1 (06/00), "Support of number portability information 
         across B-ISUP", 14 pages.
     -  Supp. 3 (05/98) to Series Q, "Number portability - Scope and
         capability set 1 architecture", 48 pages.
     -  Supp. 4 (05/98) to Series Q, "Number portability - Capability set 1 
         requirements for service provider portability (All call query and 
         Onward routing)", 28 pages.
     -  Supp. 5 (03/99) to Series Q, "Number portability - Capability set 2 
         requirements for service provider portability (Query on release 
         and Dropback)", 48 pages.
