There's a couple of considerations here.

First, how many public Internet addresses do you have?  Can you assign a
separate, public address to each piece of equipment?

If you can assign one of each, a hub or simple router may be all you need.

If you only have one public address, you'll need something that can route
traffic from multiple internal addresses to a single external.  Some docs
refer to this as "IP Masquerading".

In any case, you'll need to accomplish two things - tying all the machines
together, and tying them to the ISDN line.

For instance, I have a cable modem with one public address.  I have a
Linux box which I use as an IP-Masquerading router.  It has an internal
and an external interface, and routes any traffic for the outside world
from the internal network.  The packets look like they are coming from the
same piece of hardware on the same IP address.  The external interface
jacks right into the cable modem.  The internal plugs into a standard hub,
with drops running for the other three.

A hub of some sort, and a router of some sort.  You may be able to get
both in one package, depending on your needs.

If you want more specific help, please feel free to email me personally.
This really isn't Sparcbook specific, so may be offtopic for this
particular mailing list.
