IMS ISDN Configuration

IMS ISDN Terminal adaptor features

4 X UTP (rj45) LAN ports

This set-up will be using the following outline configuration to make the configuration as easy as possible.

We will be using "NAT" to allow only one TCP/IP address to be seen by the internet all the other addresses used internally will be hidden.
We will be using the Adaptor to assign the TCP/IP addresses using the built in DHCP system.
We will be assuming that the ISP will be assigning a DYNAMIC TCP/IP address (it could be different every time we log on) as this will work with all ISP's.
We will be setting up the adaptor for IMS EMAIL & Internet browser access only. 
The Adaptor can be configured using a Java enabled web browser and is achieved by following the steps below:-

1) Connect the ISDN terminal adaptor to a UTP port on the network and to the ISDN wall socket.

2) Configure the PC by setting the TCP/IP address to same subnet as the adaptor I.E. and the subnet mask to

3) Start the web browser and enter the address of the adaptor (default "" this will start the configuration manager built into the adaptor. 

4) Type the password (default is "root")

5) You are now asked to change the system password, enter the new password and confirm it. (please do not forget it as without it you cannot re-configure the adaptor)

6) Enter the DATA (ISDN) and VOICE (telephone) numbers you should have 2 ISDN line numbers, as you are not using the voice side of the adaptor please ignore the Telephone numbers on the right hand side.

7) The default network TCP/IP address is 192.168.0 if this is acceptable for your system the default gateway address becomes and the subnet mask becomes (these can be changed but it is not recommended)

8) Ensure that you have selected DHCP by putting a TICK in the selection box on the left hand side of the screen.

9) Ensure the settings for the first 3 box's are 252

10) The next two box's need the Primary & Secondary DNS server addresses (these are different for each ISP)

For example the 

Freeserve numbers are:- Primary DNS Secondary DNS
Pipex numbers are:- Primary DNS Secondary DNS

11) The next screen allows you to select NAT, please ensure that the tick has been placed in the box on the left hand side.

12) The next screen is asking for the ISP data, enter the data as requested and keep the "CHAP or PAP" setting.

13) The next screen is setting up the "MP" or MultiPort setting, this is only used if your ISP supports this feature, in this example we will NOT be using MP.

14) The next screen covers Remote TCP/IP addresses, please select "Remote device will tell me when we connect"

15) The next screen covers "Local TCP/IP Address on WAN", please select "Remote device will tell me when we connect"

16) The next screen allows you to finish & save the settings you have chosen.

17) You should now reboot the adaptor and then ping from a either Real/32 or a Windows system, this will test the route you have set-up. The ISDN adaptor should dial your ISP and you should get a reply (the first reply will always we slower as the adaptor has to dial and set-up the route.

18) Subject to the ping test above you should now be able to use the adaptor to collect Email from the internet on your IMS Email system.

19) Providing access to the World Wide Web from an Internet browser is a matter of setting the default route on the client to the TCP/IP address of the adaptor.
