If you look on eBay now, there’s a modern-ish MultiTech modem rack that literally has 7 desktop modems in it. On the rear of the crate, the DB25 sticks out and they have a power harness with 5.5mm coaxial power plugs.
The one I had years ago was the more conventional plugin card type. Killing myself for not keeping it.

We did exactly that at Digex, we pushed those PM-2Es hard. In the
beginning we held the modems on rack-mounted shelves, but we had a lot
of problems with overheating, We initially spaced them out with Legos
(yes, Legos!), but we quickly replaced them with custom-made metal trays
with spacer pins as soon as we could afford to do so.
(When courting $100K+/mo contracts with datacenter tours, one must
establish credibility and build trust...and one doesn't do that with Legos.)
