Thanks in advance for helping out a newbie

I work for an agency; we're being asked by a distributor is we can supply something like what's in the photo below....the black, rectangular things in the upper righthand corner that appear to be attaching to the blocks

Can you supply a better picture of the item needed?

Thanks Dave

I will try (what I uploaded was the only picture I was sent)

Thanks!

Its a building entrance system
Google Enterphone 2000 and you can go to their website

Look Here

Those are connectorized RJ71C jacks. They provide a series T&R connection for up to 12 CO lines each. They are typical for door-answering and gate-control intercom systems for multiple tenant environments.

In trying to search Enterphone phone more it appears it may have gone to a company Viscount in B.C.

try www.viscount.com

They have enterphone listed but new product
Maybe they have manuals on yours.

Good luck

"the black, rectangular things in the upper righthand corner that appear to be attaching to the blocks" are simply Amphenol connectors where the cable exits the top of the housing instead of at a right angle.
