First off, your 10MBps will not slow down ISDN. 10MBps is about 100 times faster than dual ISDN (to put in perspect a T1, at 1.54 MBps is about 1/8th the speed -- give or take due to network conditions).

How to set up:

1. The ISDN modem goes to the ISDN connection.

2. From the ISDN modem, you need to hook into some form of gateway/router. You could use Windows NT and use IP forwarding, but this could cause an unnecessary toll on the server.

Since NT is not the best option, the otheroptions depend on what you are trying to accomplish.

From experience with cable connections, I know that DLink makes a variety of devices for cable and ISDN. Their cable/DSL devices are wonderful as most supply some form of Network Address Translation (NAT) so your entire network can share a single connection. Some, if not all, of the devices also provide a firewall. They are also relatively inexpensive and allow you to hook up to your network without changing a lot.

One downside. The devices I have used use one of the IANA class B internal network addresses. If you are not using this address scheme, you may have to alter your network (hopefully on DHCP for simplicity) to set this up. If you are on DHCP, this can be done in short time. If each client is static, this could be a pain.

Depending on the number of users, you may find that you outgrow ISDN quickly. Set Internet policies for the company before hooking up, as surfing is addictive to many employees.

I hope I have covered everything that you need.

Gregory this was very helpful but I still have some questions???
15 clients are all static IP set up and being a Truck Dealership whose server and repeater have much restrictions due to being owened by GMC and not the dealership we have limitedaccess ! Here are my concerns !
(1)The only thing avaliable in this area is ISDN. (2) All 15 clients are either connected to network by a port on the 8 port repeater or a 24 port 10mbps hub uplinked to the repeater. I need to connect this ISDN to the network so everyone can access the web thru this ISDN from their desktops. Again GMC gives us very limited or no access to configure anything on the Win NT server. All shared info to and from Factory is linked by Micro wave Dish ,not that this has any bearing on the ISDN line. Thanks again for your replys.

The expensive way: Get a Proxy Server or Firewall with NAT (name translation), learn it, deploy it, maintain it. Cost Unknown!

The cheap way: Get a router from Linksys
link it to your ISDN (you should be using some type of DSL), follow the instruction that comes with the router and you'll have, besides a builtin firewall, DHCP server and a good NAT, a maintenance free piece of equip. Cost: under $200.00
Check out Amazon.com and look for Linksys router or go to

Good luck!
