Rewiring weird home phone wiring for Avaya Partner System

[samhuangavaya]

Hi,

I'm trying to install an Avaya Partner ACS System into a home. The house has Cat 3 drops in most rooms so about 8-10 drops total. Might even need to put more in on the first floor as there's only one for that entire floor. I took a look at the box outside the connects the landline to the rest of the house- and I have no idea what's going on there. The box says SBC SNET Telephone Network Interface. I thought inside there might be a splitter or something... I've never worked with actual POTS lines before- I've only worked with cable modems, SIP trunking, etc.

There are three cat 3 cables that come out of this box that go into the house. Weird because there are more than 8 phone jacks in the house and all of them work.

Any way to get a Partner System wired into this?

Thanks for the help!

Here are some pictures: (there was a bush infront of the box so it was hard to get a good angle)

I would trace where those (3) cables go to into the house. I would check the basement if they have one. Those 3 wires are probably terminated onto a 66 block and then the wiring to each room/jack is also probably brought to that location.

If that is not the case and there is no other junction box/66 block inside the house then the person who wired the house probably daisy-chained the wiring versus running home runs for each location. If that is the case, you will need to re-wire to get the Partner to work. You can daisy chain pots lines from jack to jack and it will work fine. Many older homes have this type of wiring. If it was built in the past 10 years, I would think they would've home run each wire.

Ok, found the entry point and followed the cables. One cable goes to the first floor jack and two cables just go up. Could there be a 66 block in the attic or somewhere? Maybe the builder was lazy and didn't want to run cable for that long.

And the house was built in 2003-2004.

Though if it is daisy chained (my worst fear) could I plug that daisy chained cable into the Partner System still have regular phones on those jacks? Maybe I could just run new cable where a 18D phone is necessary.

I think the reason there's 2 cables going up is that there was an 2nd floor addition.

This is weird as I know the house is wired for coax and all of those are home run.

Visual inspection and toning out the pairs will reveal if the jacks are daisy-chained. If you see two cables behind the jacks, a caution light should turn on.

Now if there are wired jacks in every room, they are all currently functional and there are only 3 runs up from the basement, I would say that the chances are good that the jacks are wired together.

With the Partner ACS its one system phone for one port in the system. You can connect an analog SLT to a system phone, but you cannot connect two system phones to a single controller port.
