Assigning Network Information - Nortel Express Installation Manual

Assigning network information

You must manually assign an Internet Protocol (IP), a Subnet mask, and a
default Gateway IP address to the Voice Services card through the serial port
interface, using these functions:
• lnIsa_writeIP
• lnIsa_writeSubnetMask
• InIsa_writeGW

All these commands are case specific. If you enter any part of the
command in the incorrect case, the command fails. Also, the first letter in each
function is a lowercase 'l' (as in lima), and the third letter in each function is an
uppercase 'I' (as in Indigo).
These functions set the IP address, the Subnet mask, and default Gateway IP
address respectively, and store them in the Non Volatile RAM (NVRAM). When
the system is restarted, the Voice Services card retrieves the network information
from NVRAM.

To assign or change the IP address, Subnet mask, and the default
Gateway IP address
Make sure you have a valid IP address (ELAN), Subnet mask, and default
Gateway IP address for the Voice Services card. Use this procedure to assign an
IP address, Subnet mask, and default Gateway IP address if commissioning the
card for the first time. Also, use this procedure if you want to change network
details associated with the card. If you are not commissioning the card for the
first time, ensure you make the changes in a scheduled maintenance slot.
Assignment of an IP address requires care to ensure that you have
a unique IP address, the correct Subnet Mask, and the correct
default Gateway IP address. An incorrect IP address or Subnet
Mask can bring down the LAN to which the card is connected. An
incorrect Gateway Address means that the card is inaccessible
beyond its local LAN.
