Dear jetes,
A conglomeration of several modems is called a modem bank. The specialized
hardware you need to set up a modem bank is called a modem chassis. This
is essentially a box with many slots into which you can plug modem cards.
To give you an idea of what a modem chassis looks like and how much
you can expect to pay for one, here is a current listing from eBay for
a seven-slot chassis made by Microcom, which was one of the foremost
manufacturers in the heyday of modem banks.

If you search for the word "chassis" on the following page, you will
find listings for several 16-slot modem chassis from Microcom. Because
modem banks are an obsolescent technology with little demand nowadays,
you will most likely have to buy a used modem chassis.

Another name for a modem chassis is "modem rack". The following product
listing includes several Microcom 16-slot racks, along with Microcom
modem cards. National Data Mux, the company selling these and other
used networking products, will send you a catalog if you fill out their

A good alternative to setting up a standalone modem rack is the
Rapidport/4 modem from Digi. The Rapidport/4 is a single unit that
contains four integrated modems. It plugs into your PC's USB port,
and it also has a port that lets you hook up additional Rapidport/4
units. You can link up to five of these units for a total of 20 modems
on a single PC.
The Rapidport/4 four-port USB modem module is a flexible USB based
remote access solution for Windows platforms. This external,
user-installable solution plugs into an existing USB port of a
PC, thin client or server, providing four 56K V.92 modems.
With its built-in USB hub, you can daisy-chain up to five
Rapidport/4 units for up to 20 modems from a single USB port
on your PC or server. Rapidport/4 gives network users access
to ISP, fax and other dial-up applications supported by Windows
operating systems.

Finally, you can buy multiport modem cards with room to plug in up to
eight modems, which you must buy separately.
