Talk:66 block

All American?
Excellent article and useful to me in New York. But is this equipment standard anywhere else besides the former Bell System? Anywhere else on Earth? 68.161.43.51 17:58, 24 October 2006 (UTC)
 * Not just the old Bell System, but standard throughout North American telecoms practice and some other parts of the world as well. They are not universal, however; for example the U.K. and some European countries adopted the Krone blocks rather than the "66" block.  87.114.233.219 (talk) 14:12, 9 September 2013 (UTC)

66 vs. 110
Where do these names come from? Some kind of measurement or just an arbitrary designation. Please add to article. Thanks. ---Ransom (71.4.51.150 18:05, 9 July 2007 (UTC))


 * Probably Western Electric catalog numbers. Alas, unlike 68000 or 8088, such numbers lack worldwide recognition.  Jim.henderson 17:47, 13 July 2007 (UTC)
 * Yes, they designations come from the original part numbers. 87.114.233.219 (talk) 14:12, 9 September 2013 (UTC)

Legacy Devices?
"Currently, 66 blocks are considered legacy devices"? I'm still installing them, and seeing plenty of others install them. I'm thinking this is subjective and should be supported by something, not just stated in the article. —Preceding unsigned comment added by Jmaslak (talk • contribs) 20:42, 24 August 2010 (UTC)
