2 Introduction – System Overview
In a typical telephony system, the network setup is the interconnection between Base-stations, “fat” routers,
repeaters, portable parts, etc. The back-bone of the network depends on the deployment scenario, but a ring or hub
topology is used. The network has centralized monitoring, and maintenance system.
The system is easy to scale up and supports from 1 to 249 bases in the same network. Further it can support up to 20
registered handsets (RTX8630, RTX8830 and RTX8430). The Small and Medium Scale Enterprise (SME) VoIP system
setup is illustrated below. Based on PoE interface each base station is easy to install without additional wires other
than the LAN cable. The system supports the IP DECT CAT-IQ repeater RTX4024 with support up to 5 channels
simultaneous call sessions.
The following figure gives a graphical overview of the architecture of the SME VoIP System:
2.1 Hardware Setup
SME network hardware setup can be deployed as follows:
Base-station(s) are connected via Layer 3 and/or VLAN Aware Router depending on the deployment requirements.
The Layer 3 router implements the switching function.
The base-stations are mounted on walls or lamp poles so that each base-station is separated from each other by up to
50m indoor
1
(300m outdoor). Radio coverage can be extended using repeaters that are installed with same distance
to base-station(s). Repeaters are range extenders and cannot be used to solve local call capacity issues. In this case
additional bases must be used.
The base-station antenna mechanism is based on space diversity feature which improves coverage. The base-stations
uses complete DECT MAC protocol layer and IP media stream audio encoding feature to provide up to 10
simultaneous calls.
