IP DECT:
1. IP DECT
The DECT over IP system comprises the following components:
· IP DECT Base Stations
These are connected to the LAN. Up to 32 base stations are supported for IP Office, with each able to host up to 8
simultaneous calls. Different models of bases station are available for indoor and outdoor location usage, using
either mains outlet power or Power over Ethernet (PoE). The base stations use G711, G723.1 and G729ab on the
LAN side.
· Avaya DECT Mobility Manager (ADMM)
One base station is used as the management interface to the IP DECT network. This base station is referred to
as the ADMM. It is managed using network access from a web browser.
· Licensing
The IP DECT system is licensed through entry of a license key into the IP DECT system configuration. The
license controls the number of base stations supported.
· IP Office Control Unit
The IP Office, ADMM and the IP Base Stations communicate across the LAN infrastructure. The IP DECT Base
Stations and the IP DECT phones communicate wirelessly.
· Voice Compression Channels
The control unit must be fitted with voice compression channels. A channel is required for all calls between an
IP DECT phone and a non-IP device such as external trunks and non-IP phones. Calls between an IP DECT
phone and other IP devices typically only require a channel during call setup. Refer to the IP Office Installation
Manual for full details of fitting voice compression channels and when channels are used.
· TFTP Server
Whenever the IP DECT base stations restart, they need to upload IP DECT application software from a TFTP
server. The IP Office Manager application is not supported for this function. An IP Office control unit with an
embedded voicemail memory card is only recommended for a small number (3 to 5) of base stations. For higher
numbers a 3rd party TFTP server application is required.
· IP DECT Phones
A maximum of 120 IP DECT phones are supported, with up to a maximum of 100 simultaneous calls (subject to
available base stations and IP Office voice compression channels if required).
· GAP Compatible
In addition to supported Avaya IP DECT phones, basic call functionality is supported for GAP compatible DECT
phones.
