3Com NBX 100 Telephone set IP programming guide.
Note: Make sure the telephone set has been initially attached to any NBX100 system with R1.1.1 or later
version of software installed. This is to insure that the telephone has the correct IP enabled software
downloaded from the NBX100 system. Also make sure that the remote chassis that you are planning to
communicate with has an IP license installed. “ IP on-the-fly license “ or “Standard IP license“.
Note: If the telephone set you are attempting to IP program is already attached to a NBX100 system please
detach it from the system at this time and cycle power by removing power from the telephone set and
reapplying power to the telephone set.
Insure that there is an available IP address for this telephone set, also be certain that there is enough
bandwidth to place this phone over a DSL, Cable Modem, Frame Relay, etc… Minimum bandwidth 56k,
64k preferred.
DHCP environments: NBX 100 telephone sets are DHCP clients and there is no need to program IP in such
settings, however the NCP (Network Call Processor)’s MAC and IP still needs to be programmed in the
telephone set.
Firewall issues: Firewalls do not allow NBX telephone sets to find the NCP remotely. The Firewall needs
to be configured to allow telephones sets to enter the corporate network.
Step by Step:


Press the PROGRAM key
The first lower right corner button with LED ( light emitting diode ) sets the IP address
 For example: 192.168.1.120, use the key pad to enter the IP address as follows:
 192 168 001 120 then press the # pound key this is to accept the IP address
 If you make a mistake while entering IP information use the oval keys under the LCD (liquid
crystal display). The outer keys will move the cursor left and right, ignore the middle oval
key under the LCD display.
 NOW press the Program key twice until the LCD displays the programming menu

To Set the Subnet Mask: Press the 2nd button from the lower right corner of the telephone set
 Enter Subnet mask and press the # pound key to accept
 For example: 255.255.255.0, #
 NOW press the Program key twice until the LCD displays the programming menu

To set Gateway: Press the 3rd button from the lower right corner of the telephone set
 Enter Gateway address and press the # pound key
 For example: 192.168.1.1, press 192 168 001 001 and then the # pound sign
 NOW press the Program key twice until the LCD displays the programming menu

To set the NCP ( Network Call Processor ) IP, press the 4 th button from the right lower corner of the
telephone set
 NCP IP is an IP that is accessible either through the WAN or the Public Internet
 For Example: 24.1.179.70, enter: 024 001 179 070 and then the pound sign #
 NOW press the Program key twice until the LCD displays the programming menu
The default MAC address should be set to ff:ff:ff:ff:ff:ff this forces the telephone set to automatically
obtain the MAC address of the NCP. Otherwise proceed with the following steps to manually program
the NCP MAC address in to the telephone set.

To set MAC ( Media Access Control) Hardware address
 The NBX telephone set needs to know the MAC address of the chassis you are trying to attach
to
 Obtain the NCP MAC address
 Make sure you that the phone is in programming mode, next press the oval key under the
PROGRAM key
 Start entering the MAC address:
 For example: 00:e0:bb:00:1c:80 <<<< every chassis has a unique MAC address
 To enter Alphabet in the telephone set use, the oval keys under the PROGRAM key, there are
6 oval keys under the PROGRAM key, form top to bottom are the letters A – F, ABCDEF
 Press the # pound key to accept the MAC address
 NOW press the Program key once and wait for the phone to reboot itself, wait until the
telephone set has been auto discovered by the remote NBX100 system. A new extension
number will appear on the display, which is an indication of your successful Voice over IP
implementation.
