I am getting a new ADSL adaptor faceplate for the NTE5 Master Socket.
The existing telephone extensions can be wired to the filtered output thus isolating the older wiring.
Now I need to run a new unfiltered ADSL extension from the faceplate to where the modem is located, in the opposite corner of the house. I propose to run suitable external grade Cat5e cable along the outside walls and use a suitable telephone or RJ45/RJ11 wall socket. It would be a nightmare to run the extension indoors through the rooms now nicely decorated.
I have searched for a simple answer regarding surge/lightning protection, without success. Opinions vary from complete "no-no" to run telephone extension (or ethernet) outdoors, to regarding it as fairly irrelevant.
Obviously, the Master Socket (MS) already has a surge protector. I understand that a direct lightning strike will fry equipment regardless of the MS surge protector anyway, and that "proper" protection is very expensive and disruptive and not done in domestic scenarios. Only BT can afford to do this but it pays off as they don't have to unplug all their equipment during a storm. For us mortals, any surge protection is really limited to static caused by distant lightning strikes or storms in general, and provided by some spark or gas discharge device between a pair of wires without any path to earth. It's a goodwill measure really, based on the fact that replacement equipment is not too expensive.
I am guessing:
(a) As the new extension is hardwired to the Master, it is already protected by the Master's internal surge device anyway.
(b) If a modern ADSL modem is connected to the new remote extension, it already has its own internal surge protector.
(c) Modem cable inline protectors are available - but in view of (b), and (a), this is probably redundant.
(d) The extra line could be terminated similarly to the Master by using an extension wall socket with just a surge protector in it (maybe by clipping out the other bits from an old style Master). This is a bit radical and for flexibility, (c) would be better.
Whilst I understand the concern to both equipment and personal safety that is expressed regarding lightning, I cannot see that being remedied without expensive installation mentioned above. I am inclined to just wire up to a standard extension box.
I was wondering if anyone has any opinions on this?
