Talk:Demarcation point

From Wikipedia, the free encyclopedia

[edit] Wrong info in the image

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)
