Phone grounding

[Den Murray]

Dumb question ....

The phone company delivers service via a pair of wires, which terminate at
their Network Interface. Extension wiring is run from this as either a star
on multiple pairs of wires, or as a chain on one pair of wires. I can see a
grounding wire going into the telco side of the NID ... what is it connected
to in the NID?

Cheers

Thanks for this. I hope you don't mind if I ask a two-part supplementary
question!

1) The ground wire from the NID (on the telco side) is a new wire, that runs
to a junction box where it is joined to what I guess is the original ground.
Is this safe, or to code?
2) The ground wire is not cross-bonded to the electricity ground. Is this
contrary to code?

Cheers
