What do the -- mean in the code table? They are explained nowhere. --87.179.117.33 (talk) 05:29, 30 March 2009 (UTC)[reply]

It's maybe a bit hard to follow, but those are the IBM 707x sign flags. They're stored using a 2-out-of-3 code, and when copied to a digit register, two bits are forced to zero, as shown. 71.41.210.146 (talk) 13:23, 25 March 2011 (UTC)[reply]

Telephone Industry (electromechanical)[edit]

When I started working at Bell Canada in 1973 (I had just come from an electronics program at Conestoga College) I was surprised to see so much electromechanical technology still in use. Both the 5xB cross-bar switch as well as the number-4 toll tandem switch employed a punched card machine (called a trouble recorder) for reporting problems to the technicians on duty. That code was the 2-of-5 code. Any card containing fields with three or zero punches was immediately discarded as junk. Neilrieck (talk) 11:02, 6 April 2015 (UTC)[reply]

Yes, it was a huge aspect of TX operations. However WP decided it wasn't important enough, so that article went. Children. Andy Dingley (talk) 22:27, 6 April 2015 (UTC)[reply]
