Need guidance configuring it all

<< < (3/3)

SnowLion:
Many thanks to all for the alerts and the great guidance.

The comments about 'overly complex' and the follow on solutions became more obvious as a result of the 'ah ha' moment provided by OE's suggestion:

"Wire a duplex wall plate top jack for Line1 and Line2 (L1+L2); wire the bottom jack for Line2 as L1 (splitter configuration like the OBi202).  The OBi Phone1 could feed the top jack; the fax machine could connect to the bottom jack or to Phone2 on the OBi."

This suggestion clarified that it was possible to feed the house phone lines via any jack in the house assuming the line is wired appropriately from jack to tel. junction box.

As for disconnecting the source from the house telephone wiring - I presume this is as simple as unplugging the single cord that the ISP ran from the ONT to the tel. junction box installed when they switched us over from copper to fiber.  Please let me know if this assumption is likely to be faulty.

As for REN 5 - many thanks for this suggestion.  I assume the fax is drawing zero or essentially zero power from the phone line as it has its own power brick?  Originally I was thinking it would be necessary to disconnect extra phones, but from your suggestion it seems we can simply turn off the ringers.  If I'm understanding correctly, this would be a great plus.

Again, many thanks to all!  Anyone have questions about genetics, genomics, or statistics so I may 'pay it forward!"

Merry Christmas and / or Happy Holidays!

I actually explained how the OBi 202's PHONE 1 jack is wired.  All you have to do is to use that knowledge to connect the two pairs of conductors to your premises wiring, whichever way is easiest -- either via a wall jack or via a punch-down junction block.  The main concept to understand is that contemporary premises telephone wiring is done with multi-conductor (usually Cat-5 or Cat-6) cable, with line 1 being blue & blue/white stripe, and line 2 being orange & orange/white stripe, and line 3 being green & green/white stripe.

I never assume anything about people's prior telephone service connections, since people often have had several different providers mess with that wiring.  IF, and only if, whoever installed FiOS also disconnected whatever was in use before that (copper POTS or cable modem), then simply unplug the telephone jack from the ONT.  If you have any doubt, use a voltmeter to measure across the line pairs.  You should see zero volts before connecting the OBi.

The blah-blah-blah from OzarkEdge about routers is irrelevant, as is his REN comment.  No modern telephone equipment uses more than a fraction of a REN.  REN was only important for ancient mechanical-bell ringer phones.  The best practice for today's residential WAN/LAN installation is as I described it in my previous post.  If you want to create a reliable and high performance system, with the least amount of complexity and ongoing maintenance of firmware, then use only one router, and use gigabit switches for the rest of the hardwired connections.  WiFi extenders will work, but the better solution is a mesh router system, which avoids having different access point SSIDs and is more robust.

Regarding isolating your house tel wiring from all other sources, it may be as simple as you noted.  Just investigate the junction box and be sure any source wiring such as a tel cable coming in from outside is fully disconnected from the house tel wiring.

The REN 5 advice is a valid consideration.  The OBi is rated REN 5 and phones are also rated.  Given you intend to feed your house wiring so that you can connect multiple phones, and without knowing anything about those phones, it's worth mentioning for your consideration.
