Setting the IP Address of the Trunk Module
When connecting a Trunk Module to the system for the first time a DHCP server is required to give the
Trunk Module an IP address. This address can be viewed within the Trunk Module’s configuration form
as described above. However once connected the Trunk Module can be given a static address as
follows:
1 Within a Command prompt enter
telnet <ip address of the Trunk Module> eg telnet 192.168.0.198
then press Enter
2 You will be prompted for a Username, enter diag, then press Enter.
3 You will be prompted for the password for this Trunk Module. By default this is 7388. Then press
Enter.
4 Wait for a # to appear to confirm a connection has been made to the Trunk Module.
5 Enter setnet then press Enter.
6 The current configuration will be displayed. You will be asked if you wish to change any of this
configuration.
7 Enter y then press Enter.
8 You will be asked how the IP address will be assigned.
9 Delete the d and enter s then press Enter.
10 Follow the onscreen prompts entering the IP address you wish to give the Trunk Module, eg
192.168.0.253, the netmask you wish to use, eg 255.255.255.0 , the IP address of the Gateway
(Default Router), eg 192.168.0.1, and the IP address of the TFTP server which will be the IP address
of the Call Server that will be providing software to the Trunk Module during an upgrade, eg
192.168.0.1.
11 At the following prompts make any changes you require otherwise press Enter to leave the option
unchanged.
12 You will be asked if you wish to save the changes. Enter
y
then press Enter
13 Telnet will display that the changes are being saved and the prompt will return once finished.
14 Enter poweroff then press Enter and the Trunk Module will reboot
Please note:
x To return to using DHCP follow the same instructions above. Enter
d
when asked how the IP address
will be assigned.
x At any prompt you may enter a
?
for help on that option or
q
to quit.
x For further information on working with Telnet please refer to page 300.
x A list of each module’s IP address can be viewed in Manager Assist by selecting System Utilities and
then IP Addresses.
Each port on the Trunk Module can now be configured independently, please refer to Working with
Trunks on page 182 and Creating a WAN Link on page 267 for further details:
Connecting a 4400 Voice Compression Module
The 4400 Voice Compression Module provides 16 channels, of 8kbps, G.729a based compression and can
be deployed to provide a higher density of calls between Call Servers over low speed WAN links.
Additional channels of voice compression can be enabled via a licence – giving a maximum of 32
compression channels per module (please refer to the Licensing section on page 20 for further
information). By using a standard LAN for interconnectivity between the Voice Compression Module and
its associated Call Server, there is no limit to the number of compression channels that can be practically
