[Asterisk-Users] asterisk home wiring question

[Jon Pounder]

Just to add some general wiring tips from my experience. (and yes you need
to go to an fxo port with the incoming telco line, and the fxs ports go to
your phones - you can't mix and match and parallel things up, the only
exception being more than one phone on an fxs port if the port can supply
enough ringing power or you turn off some of the ringers)


anyway, these are just some general tips that worked for me

- use home run wiring to a central spot even if it gets costly in cable
- run extra wire even if you think you will never need it
- use the same type of wire for everything so you can switch stuff around
later (eg: use cat6 4pr for phone jacks even though it is grossly
overrated, but you can always switch to an ipphone later without digging
into the walls again.)
- use RJ45 jacks for phone outlets as well, the RJ11 still mates fine. If
you hookup the network pairs and the phone pair, they can coexist in the
same jack and it can serve either purpose.
- use punchdown blocks even for the smallest of installations, install and
changes are just so much simpler and cleaner than any other splicing
method.
- if you have a channel bank with fxs and fxo, get a mating AMP connector
and hard wire it with an emergency configuration of lines to extensions,
if the channel bank fails, just plug the hardwired connector into your
building wiring.
- label everything clearly, and make a plan of the installation, or before
you know it you'll only be able to find one end of some of the wires.
