Talk:Demarcation point

Wrong info in the image

edit

The lower image identifies what is assumed to be a Bell Canada demarcation point. This is not completely correct - Bell Canada identifies the Telephone Network Interface Device (NID) as the demarcation device [1]. However, in older homes, the device shown may be considered a demarcation point, since they may not have a proper NID.

In addition, the image stated that the two devices on the left are threaded fuses. They are not. They are spark gap surge arrestors. One will short the tip line to ground, the other will short ring to ground. --Michael Daly (talk) 00:06, 25 February 2008 (UTC)Reply

There was another, more modern junction box on the roof, but all it contained was a connection between the aerial telephone wire and the wire that ran down to what I assumed was the demarc. The tech called them 'carbon fuses' and a lightning storm had 'blown' them. Thanks for clearing up any misconceptions Pendragon39 (talk) 07:06, 27 October 2008 (UTC)Reply

Regulation / deregulation

edit
 
One Policy. One System. Universal Service.

Why does it say "In most places this hardware existed before deregulation. " The article previous mentions regulation, is the word deregulation supposed to be regulation? — Preceding unsigned comment added by 184.175.3.5 (talkcontribs) 01:27, 23:47, 10 June 2021 (UTC)Reply

In the US the Bell System was the system of companies, led by the Bell Telephone Company and later by AT&T, that dominated the telephone services industry in North America from the invention of the telephone in 1876-1877 until the breakup of the Bell System in 1983. This is often referred to as "deregulation". There never was a period before telephone regulation; as the first telephones were installed the existing telegraph regulations were applied. --Guy Macon (talk) 01:41, 11 June 2021 (UTC)Reply
