2 Introduction – System Overview
In a typical telephony system, the network setup is the interconnection between Base-stations, “NAT” 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.
In the RTX9440 based system there is only one base station in the network. Up to 30 handsets (RTX864x or RTX8440
handset) can be registered on the base station. The system can be extended with up to 6 of the supported IP DECT
CAT-IQ repeaters RTX4026. System setup is illustrated below.
Based on PoE interface the base station is easy to install without additional wires other than the LAN cable for power.
The following figure gives a graphical overview of the architecture of the SME VoIP single cell System:
2.1 Hardware Setup
SME network hardware setup can be deployed as follows:
The RTX9440 base-station is connected via Layer 3 and/or VLAN Aware Router depending on the deployment
requirements. The Layer 3 router implements the switching function.
The base-station should be mounted on a wall in a height less than 2 meters. Radio coverage can be extended using
repeaters that are separated from each other by up to 50m indoor
1
(300m outdoor). Repeaters are range extenders
and cannot be used to solve local call capacity issues.
The base-station antenna mechanism is based on space diversity feature which improves coverage. The base-station
uses complete DECT MAC protocol layer and IP media stream audio encoding feature to provide up to 10
simultaneous calls.
2.2 Components of SME VoIP System
RTX SME VoIP system consists of (but not limited to) the following components:
