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

2.5 Advantages of SME VoIP System
They include (but not limited to):
1. Simplicity. Integrating functionalities leads to reduced maintenance and troubleshooting, and
significant cost reductions.
2. Flexibility. Single network architecture can be employed and managed. Furthermore, the architecture is
amenable to different deployment scenarios, including Isolated buildings for in-building coverage, location
with co-located partners, and large to medium scale enterprises deployment for wide coverage.
3. Scalability. SME network architecture can easily be scaled to the required size depending on customer
requirement.
4. Performance. The integration of different network functionalities leads to the collapse of the protocol
stack in a single network element and thereby eliminates transmission delays between network elements
and reduces the call setup time and packet fragmentation and aggregation delays.

3 Installation of Base Stations/Repeater
After planning the network, next is to determine the proper places or location the relevant base stations
will be installed. Therefore, we briefly describe the how to install the base station in this chapter.
3.1 Package –Contents/Damage Inspection
Before Package Is Opened:
Examine the shipping package for evidence of physical damage or mishandling prior to opening. If there is a
proof of mishandling prior to opening, you must report it to the relevant support centre of the regional
representative or operator.
Contents of Package:
Make sure all relevant components are available in the package before proceeding to the next step.
Every shipped base unit package/box contains the following items:
2 x mounting screws and 2 x Anchors
1 x Metal plate(s)
1 x Plastic stand
1 x Cat. 5 cable (Ethernet cable)
Base unit
Damage Inspection:
The following are the recommended procedure for you to use for inspection:
1. Examine all relevant components for damage.
2. Make a “defective on arrival – DOA” report or RMA to the operator. Do not move the shipping
carton until it has been examined by the operator. If possible send pictures of the damage. The
operator/regional representative will initiate the necessary procedure to process this RMA. They
will guide the network administrator on how to return the damaged package if necessary.
3. If no damage is found then unwrap all the components and dispose of empty package/carton(s) in
accordance with country specific environmental regulations.

3.3 RTX Base Unit –Reset feature
It is possible to restart or reset the base station unit by pressing a knob at the rear side of the unit.
Alternatively, it can be reset from the SME Configuration Interface. We do not recommend this; but
unplugging and plugging the Ethernet cable back to the PoE port of the base station also resets the base
unit.

3.4 Installing the Base Station
First determine the best location that will provide an optimal coverage taking account the construction of
the building, architecture and choice of building materials.
Next, mount the Base Station on a wall to cover range between 50 –300 meters (i.e. 164 to 984 feet),
depending whether it’s an indoor or outdoor installation. Please refer to chapter 10 for important
information regarding network requirements, deployment considerations, site planning, cell
coverage/capacity planning, environmental considerations and recommended Base station placement.
3.4.1 Mounting the Base Stations/Repeaters:
We recommend the base station be mounted an angle other than vertical on both concrete/wood/plaster
pillars and walls for optimal radio coverage. Avoid mounting the base units upside down as it significantly
reduces radio coverage.
Mount the base unit as high as possible to clear all nearby objects (e.g. office cubicles and cabinets, etc.).
Occasionally extend coverage to remote offices/halls with lower telephony users by installing Repeaters.
Make sure that when you fix the base stations with screws, the screws do not touch the PCB on the unit.
Secondly, avoid all contacts with any high voltage lines.

3.5 Find IP of Base Station
To find IP of the installed base station two methods can be used; Using handset Find IP feature or browser
IPDECT feature.
3.5.1 Using handset Find IP feature
On the handset press “Menu” key followed by the keys: *47* to get the handset into find bases
menu. The handset will now scan for 8660 bases. Depending on the amount of powered on bases
with active radios and the distance to the base it can take up to minutes to find a base.
- Use the cursor down/up to select the base MAC address for the base
- The base IP address will be shown in the display
The feature is also used for deployment. For further details refer to reference [2].
3.5.2 Using browser IPDECT
Open any standard browser and enter the address:
http://ipdect<MAC-Address-Base-Station>
for e.g. http://ipdect00087B00AA10. This will retrieve the HTTP Web Server page from the base station
with hardware address 00087B00AA10.
This feature requires an available DNS server.

Damage Inspection:
The following are the recommended procedure for you to use for inspection:
1. Examine all relevant components for damage.
2. Make a “defective on arrival – DOA” report or RMA to the operator. Do not move the shipping
carton until it has been examined by the operator. The operator/regional representative will
initiate the necessary procedure to process this RMA. They will guide the network administrator on
how to return the damaged package if necessary.
3. If no damage is found then unwrap all the components and dispose of empty package/carton(s) in
accordance with country specific environmental regulations.
4.2 Before Using the Phone
Here are the pre-cautions users should read before using the Handset:
Installing the Battery
1. Never dispose battery in fires, otherwise it will explode.
2. Never replace the batteries in potentially explosive environments, e.g. close to inflammable liquids/
gases.
3. ONLY use approved batteries and chargers from the vendor or operator.
4. Do not disassemble, customise or short circuit the battery
Using the Charger
Each handset is charged through the use of a handset charger. The charger is a compact desktop unit
designed to charge and automatically maintain the correct battery charge levels and voltage.
The charger Handset is powered by AC supply from 110-240VAC that supplies 5.5VDC at 600mA.
When charging the battery for the first time, it is necessary to leave the handset in the charger for at least
10 hours before the battery is fully charged and the handset ready for use.
Handset in the Charger
For correct charging, ensure that the room temperature is between 0°C and 25°C/32°F and 77°F. Do not
place the handset in direct sunlight. The battery has a built-in heat sensor which will stop charging if the
