How to wire Inter-Tel Axxess LSC and DKSC16+ from DB9's 2

[GPower2012]

Hello, I am badly in need of wiring instructions for my Inter-Tel Axxess LSC and DKSC16+. Both came with 25-pair DB9's. Does anyone have wiring instructions?

DKSC16 uses the first 16 pairs straight through, they are polarity conscious mind so check you have them the right way around by wiring up the first white blue pair and checking the phone comes up.

LSC from what I can remember is the same, Blues are line 1, oranges are line 2 etc.

Also, The older Axxess (Pre-Mitel) digital endpoints use the secondary station cable pair (WHT/OR, OR/WHT.

The LSC will only give you lines 1-4 (Pairs 1-4), unless you add a daughter board to it, increasing it to 8.

True for the oldest Inter-Tel phones the Standard, Executive ones etc but the Inter-Tel 8520 and 8560 only need one pair.

@NTEDave: Yes, the Axxess Digital 8560/8520 use one pair, the secondary STATION CABLE pair (OR). Same as the Executive and Standard endpoints.

The Mitel Digital endpoints 8568/8528 use the Primary STATION CABLE pair (BL).

Wow, thank you. My troubles are:
1. phone systems are not my core strength.
2. I started the process by wiring the LSC incorrectly: I stripped the DB9 to this card and wired 5 incoming lines from a cable modem's terminated Cat-3 female, each to a Cat-3 cable with males on both ends, each to 5 Cat-3 females, each of which has 1 pair of wires: Blue, Brown, Orange, Violet, & Green pairs.
3. Next, I stripped the DB9 to the DKSC16+ and terminated 2 pairs of wires into each of my 8 Cat-5e jacks, so that I could connect to existing wiring: example: the blue/white pair and the orange/white pair went into the 1st Cat-5, etc...

Now I only have 8 actual extensions. If you were in my sheos, and had a limited budget, what would be the best fix?

GPower2012,
I'm not sure why you have DB9's in your wiring. I use a 10 '25PR FEMALE tail and terminate it to a 66M1-50 block, 110 block, or a patch panel. This will give you all (16) circuits. You can then cross-connect or patch to the station cable.

You have wired two phone extns to one CAT5 port.

White Blue / Blue White would go to Port 1 on a CAT5 patch panel

White Orange / Orange White would go to port 2 on a CAT5 patch panel

And so on up to the sixteen pairs.
