Total newbie to Partner ACS - please help ?!?

[smith1660]

Hi Forum Folks.

I hope you might help to direct me a bit, please ??

I work for a very small office which has recently re-signed a centrex contract for POTS lines.
It has ancient phone equipment as well.
Since we are stuck with POTS lines for some years due to a very high breach fee in the contract - the switch to VOIP must be delayed until then.

In the meantime it is necessary to have decent phone equipment.

I was able to pick up a very clean Partner ACS system & phones as a lot from another business which has switched to VOIP and no longer needed it.
It was sold as fully functional and I would like to install this system in place of the really ancient system that is in use now.

It consists of an expansion box with 4 system components, a backup card and an assortment of phones.

Trouble is, I have zero experience with the Partner ACS systems.

My prior work has included all sorts of other systems starting decades ago with Siemens, Comdial, Nitsuko and Dash/Picazo systems - so I am somewhat able to relate with the subject matter.

My queries, please:
- Any help in precisely identifying the equipment I have on hand will be wonderful - perhaps there is some list someplace of model numbers and versions I can use for this ??
(Thus far I have been unable to find such a thing by searching the internet.)

- Any help in finding the most basic & simple starting-from-scratch sort of guide to get from a pile of parts to an installed, working phone system ??

There are manuals which came with the system.
The main one is dated 1997 and I suspect the system is newer than that and/or has been updated, but I do not know how to confirm this.

The only coherent (model ??) number found thus far is:
103G15/16G16(28)

Any help and/or guidance will be hugely appreciated !!

Thank You.
