2Introduction – 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 40 bases in the same network. Further it is able to
support up to 200 registered handsets (RTX8630 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 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 extended using repeaters that are
installed with same distance to base-station(s).
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.

2.2 Components of SME VoIP System
RTX SME VoIP system is made up of (but not limited to) the following components:
•At least one RTX Base Station is connected over an IP network and using DECT as air-core interface.
•RTX IP DECT wireless Handset.
•RTX SME VoIP Configuration Interface; is a management interface for SME VoIP Wireless Solution. It
runs on all IP DECT Base stations. Each Base station has its own unique settings.
2.2.1 RTX Base Stations
The Base Station converts IP protocol to DECT protocol and transmits the traffic to and from the end-nodes
(i.e. wireless handsets) over a channel. It has 12 available channels.
In a multi-cell setup, each base station has:
•8 channels have associated DSP resources for media streams.
•The remaining 4 channels are reserved for control signalling between IP Base Stations and the SIP/DECT
end nodes (or phones).
Base Stations are grouped into clusters. Within each Cluster, Base Stations are synchronized to enable a
seamless handover when a user moves from one base station coverage to another. For synchronization
purposes, it is not necessary for Base Stations to communicate directly with each other in the system. E.g. a
Base Station may only need to communicate with the next in the chain. It is advisable for a Base Station to
identify more than one Base Station to guarantee synchronization in the situation that one of the Base
Stations fails.
The 4 control signalling channels are used to carry bearer signals that enable a handset to initiate a
handover process.
2.2.2 SME VoIP Administration Server/Software
This server is referred to as SME VoIP Configuration Interface.
The SME VoIP Configuration Interface is a web based administration page used for configuration and
programming of the base station and relevant network end-nodes. E.g. handsets can be registered or de-
registered from the system using this interface.
The configuration interface can be used as a setup tool for software or firmware download to base stations,
repeaters and handsets. Further, it is used to check relevant system logs that can be useful to
administrator. These logs can be used to troubleshoot the system when the system faces unforeseen
operational issues.
2.2.3 RTX Wireless Handset
The handset is a lightweight, ergonomically and portable unit compatible with Wideband Audio (G.722),
DECT, GAP standard, CAT-iq audio compliant.
The handset includes Colour display with graphical user interface. It can also provide the subscriber with
most of the features available for a wired phone, in addition to its roaming and handover capabilities. Refer
to the relevant handset manuals for full details handset features.
2.3 Wireless Bands
The bands supported in the SME VoIP are summarized as follows:
Frequency bands: 1880 –1930 MHz (DECT)
1880 –1900 MHz (10 carriers) Europe/ETSI
1910 –1930 MHz (10 carriers) LATAM
1920 –1930 MHz (5 carriers) US
