L-1 introduction
[edit]There seems to be some confusion here about when L-1 was introduced. The chart shows L-1 starting in 1941, but the text references the 1930s, and the AT&T Long Lines page says it started in 1936. 64.81.163.112 (talk) 18:05, 27 August 2009 (UTC)
L2 reference
[edit]Where did the data on L2 come from?
I can't find mention of it in BSTJ or other sources. L1, L3, etc fine.... but the L2?

L3I subtype missing
[edit]No mention at all of L3I? L3I was L3 'Improved', which simply meant that it was further hardened against EMP and Nuclear strikes. The L3I circuits were used by the AUTOVON network for US nuclear forces command and control. (A pretty important use of L-Carrier). — Preceding unsigned comment added by NYGuy315 (talk • contribs) 01:26, 9 December 2019 (UTC)
Disregard, I now see that L3I is mentioned, albeit in a single mention.. NYGuy315 (talk) 01:27, 9 December 2019 (UTC)
Inventor of coaxial cable
[edit]The claim that Lloyd Espenschied invented coax is dubious. Coax was invented by Oliver Heaviside and patented by him in 1880. See Oliver Heaviside: The Life, Work, and Times of an Electrical Genius of the Victorian Age, and surely the transatlantic telegraph cable was in essence coaxial. Espenschied may have discovered the cable geometry independently, but he was not first. SpinningSpark 12:13, 19 December 2018 (UTC)
