Avaya IP-DECT System Description

IP-DECT System

The major parts of the Avaya IP-DECT system are the IP-DECT Base Station (IPBS) and
IP-DECT Gateway (IPBL) consisting of the software components DECT Radio (interface) and
DECT Master.
There is only one DECT Master in a single site IP-DECT system. In a multiple site IP-DECT
system, each site is connected with the PBX through an own DECT Master and an H.323
XMobile trunk.
The IPBS/IPBL is connected to an IP network through the LAN interface, which provides
connectivity to the IP-PBX.

System layout

All IPBSs/IPBLs are connected to the LAN, but it is only the DECT Master that have a logical
connection to the IP-PBX. It is a flat layout where all DECT Radios are logically communicating
directly to the DECT Master, see
Figure 2: Logical connections of the software components DECT Master and DECT Radio
DECT Master
The DECT Master is a software interface between the IP-DECT system and the IP-PBX. The
DECT Master is responsible for all DECT handsets in the system.
The DECT Master knows which DECT Radio the handsets are located to, that is which DECT
Radio in the system that received the latest location registration message from the handset. A
call to a handset is directed only to the DECT Radio where the handset is located. Thus limiting
the H.323 XMobile and DECT load in the system.
