PROGRAMMING IP EXTENSIONS

Up to 12 IP extensions can be equipped on the Broadband Module. These extensions can be
located on the LAN and at remote locations. The Mitel 5330 IP Phone must be used for the IP
extensions.
Note that other manufacturers' IP phones will not work with the system.
Note
Refer to the Mitel 5330 IP Phone Quick Reference User Guide for setting up and connecting
the phone you will find this manual on your Documentation CD that came with your Mitel 3000
system.
When equipping extensions remotely it is important to ensure that there is sufficient
bandwidth available to the Broadband Module to support the extensions.

ANDWIDTH EQUIREMENTS
The IP extensions can be programmed to use either G.711 or G.729 codecs. The G.711
codec supports speech at 64kbps and G.729 supports speech at 8kbps. However the
bandwidth needed to support the IP and proprietary-signalling requirements exceeds these
figures.
When using the G.711codec the bandwidth allowance for each active remote extension
should be 100kbps.
When using G.729 codecs the bandwidth allowance for each active remote extension should
be 50kbps.
This bandwidth is required in both the upstream and downstream directions and does not
include the additional bandwidth required for data communications.
The limiting factor for ADSL lines is the speed in the upstream direction. This speed is
significantly lower than the downstream.
It is recommended that if multiple remote extensions are required that a symmetrical DSL
service is used. This is connected to the system by means of an external modem. See page
16.

ETTING UP XTENSIONS
Before attempting to program IP extensions it is important that the following are checked: -
- If any of the IP extensions are located remotely ensure that the broadband service is
connected to and working on the Broadband Module. The VoIP programming is not
available unless an IP address is provided on the WAN interface. This address is shown
on the status page. See page 56.
- The broadband service provides a static IP address.
- If the IP extensions are located on the LAN only and no broadband service is supported
then the VoIP interface must be changed to IP LAN. See page 25.
A STATIC IP address MUST be provided by your DSL provider if IP extensions
are to be used remotely.
