2 Introduction – System Overview
In a typical telephony system, the network setup is the interconnection between Base-stations, 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. It is able to support up
to 200 registered handsets. 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 with support for up to 5 channels
simultaneous call sessions.
The following figure gives a graphical overview of the architecture of the BT Business DECT System:
2.1 Hardware Setup
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, desk tops or lamp poles so that each base-station is separated
from each other by up to 50m indoor1 (300m outdoor). Radio coverage can be 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 BT Business DECT System
Fijowave BT Business DECT system is made up of (but not limited to) the following components:
•
At least one Fijowave Base Station is connected over an IP network and using DECT as air-core
interface.
•
Fijowave IP DECT wireless Handset.
•
Fijowave BT Business DECT Configuration Interface; is a management interface for BT Business DECT
Wireless Solution. It runs on all IP DECT Base stations. Each Base station has its own unique settings.
2.2.1 BT 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 BT Business DECT Administration Server/Software
This server is referred to as BT Business DECT Configuration Interface.
The BT Business DECT 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.
The handset is a lightweight, ergonomical 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 BT Business DECT are summarized as follows:
Frequency bands:
1880 – 1930 MHz (DECT)
1880 – 1900 MHz (10 carriers) Europe/ETSI
1910 – 1930 MHz (10 carriers) LATAM

2.5 Advantages of BT Business DECT System
They include (but not limited to):
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.

Chapter: Introduction – System Overview
1. Simplicity. Integrating functionalities leads to reduced maintenance and troubleshooting, and
significant cost reductions.

3.2 BT Base Unit – Reset feature
Chapter: Installation of Base Stations/Repeater
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 BT Business DECT 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.
BT Business Multi Cell DECT System Guide V1.0

3.3 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 or desk to cover range between 50 – 300 meters (i.e. 164 to 984
feet), depending whether it’s an indoor or outdoor installation.
3.3.1 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.
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.
BT Business Multi Cell DECT System Guide V1.0
Chapter: Installation of Base Stations/Repeater
Mount the base unit as high as possible to clear all nearby objects (e.g. office cubicles and cabinets, etc.).
Extend coverage to remote offices/halls with lower telephony users by installing Repeaters.
11
3.4 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.
3.4.1 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 220 bases.
- 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.
3.4.2 Using browser IPDECT
Open any standard browser and enter the address:
http://ipdect<MAC-Address-Base-Station>
for e.g. http://ipdect38B74D000001. This will retrieve the HTTP Web Server page from the base station
with hardware address 38B74D000001.
This feature requires an available DNS server.
3.5 Login to Base SME Configuration Interface
STEP 1
Connect the Base station to a private network via standard Ethernet cable (CAT-5).
STEP 2
Use the IP find menu in the handset (Menu *47*) to determine the IP-address of the base
station by matching the MAC address on the back of the base station with the MAC address list in
the handset.
STEP 4
Once you have authenticated, the browser will display front end of the SME Configuration
Interface. The front end will show relevant information of the base station.

BT Business Multi Cell DECT System Guide V1.0
Chapter: Preparing the Handset
Before Using the Phone
Here are the pre-cautions users should read before using the Handset:
14
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
battery temperature is too high.
If the handset is turned off when placed in charger, only the LED indicates the charging. When handset is
turned off, the LED flashes at a low frequency while charging and lights constantly when the charging is
finished. There will be response for incoming calls.
If the handset is turned on when charging, the display shows the charging status.
Open Back Cover
1. Press down the back cover and slide it towards the bottom of the handset.
2. Remove Back Cover from Handset
Replace Battery
Remove Back Cover from Handset. Remove the old battery and replace with a new one.
BT Business Multi Cell DECT System Guide V1.0
Chapter: Preparing the Handset
Handset Serial Number
The serial number of each handset is found either on a label, which is placed behind the battery, or on the
packaging label. First, lift off handset back cover and lift the battery and read the serial number.
15
5 BT Business DECT Administration Interface
The BT Business DECT Administration Interface is also known as BT Business DECT Configuration. It is the
main interface through which the system is managed and debugged.
The BT Business DECT Configuration Interface is an in-built HTTP (s) Web Server service residing in each
base station. This interface is a user friendly interface and easy to handle even to a first time user.
Note: Enabling secure web will decrease web server speed perceived by the user. The MS internet explorer
caches more data and as such this browser is recommended in secure web mode.
This chapter seeks to define various variables/parameters available for configuration in the network.

5.3 Extensions
In this section, we describe the different parameters available whenever the administrator is creating
extensions for handsets. Note, it is not possible to add extensions if no servers are defined. This section also
describes the administration of extensions and handsets using the extension list and the extension list
menu.
Software supports customer configurations with and without the multiline feature. Section 5.3.1 describes
“add extensions” without multiline and 5.3.2 with “multiline”.
The system can handle maximum 200 extensions matching 200 handsets which can be divided between
servers. When 200 handsets are registered it is not possible to add more extensions. With active multiline
feature the system can handle maximum 200 extensions. With 4 active lines maximum 50 handsets can be
active in the system.
Chapter: BT Business DECT Administration Interface
Note: Within servers or even with multi servers, extensions must always be unique. This means same
extension number on server 1 cannot be re-used on server 2.

Select UDP, TCP, TLS 1.0
When SIP Transport is set to TCP or TLS, a TCP (or TLS)
connection will be established for each SIP extension. The
source port of the connection will be chosen by the TCP
stack, and hence the local SIP port parameter, specified
within the SIP/RTP Settings will not be used. The “Signal
TCP Source Port” parameter specifies if the used source
port shall be signalled explicitly in the SIP messages.
When using TCP or TLS as SIP transport, choose if a
TCL/TLS connection
shall be established for each SIP extension or if the base
station shall establish one connection which all SIP
extensions use. Please note that if TLS is used and SIP
server requires client authentication (and requests a
client certificate), this setting must be set to disabled.
0: Disabled. (Use one TCP/TLS connection for all SIP
extensions)
1: Enabled. (Use one TCP/TLS connection per SIP
extensions).
If disabled RTP stream will be send from the base, where
the handset is located. By enable the RTP stream will
always be send from the base, where the SIP registration
is made.
This directive defines the window period (30 sec.) to

Specify the hold behaviour by handset hold feature.
RFC 3264: Hold is 33nalyse33n according to RFC 3264, i.e.
the connection information part of the SDP contains the
IP Address of the endpoint, and the direction attribute is
send only, recv only or inactive dependant of the context
RFC 2543: The ”old” way of 33nalyse33ng HOLD. The
connection information part of the SDP is set to 0.0.0.0,
and the direction attribute is send only, recv only or
inactive dependant of the context
When we have two calls, and one call is on hold, it is
possible to perform attended transfer. When the transfer
soft key is pressed in this situation, we have traditionally
also put the active call on hold before the SIP REFER
request is sent. However, we have experienced that some
PBXs do not expect that the 2nd call is put on hold, and
therefore attended transfer fails on these PBXs.
The "Attended Transfer Behavior" feature defines
whether or not the 2nd call shall be put on hold before
the REFER is sent.
If "Hold 2nd Call" is selected, the 2nd call will be held
before REFER is sent.
If "Do Not Hold 2nd Call" is selected, the 2nd call will not
be held before the REFER is sent
Default disabled.
By enable the system codec priority during incoming call
is used instead of the calling party priority.
E.g. If base has G722 as top codec and the calling party
has Alaw on top and G722 further down the list, the
G722 will be chosen as codec for the call.

5.7 Time Server
In this section, we describe the different parameters available in the Time Server menu.
The Time server supplies the time used for data synchronisation in a multi-cell configuration. As such it is
mandatory for a multi-cell configuration. The system will not work without a time server configured.
As well the time server is used in the debug logs and for SIP traces information pages, and used to
determine when to check for new configuration and firmware files.
NOTE: It is not necessary to set the time server for standalone base stations (optional).
Press the “Time PC” button to grab the current PC time and use in the time server fields.
NOTE:
When time server parameters are modified/changed synchronisation between base stations can take up to
15 minutes before all base stations are synchronised, depending on the number of base stations in the
system.

5.9 Security
The security section is used for loading of certificates and for selecting if only trusted certificates are used.
Furthermore, web password can be configured.
The Security web is divided into three sections: Certificates (trusted), SIP Client Certificates (and keys) and
Password administration.
To setup secure fwu and configuration file download select HTTPs for the Management Transfer Protocol
(reference 0)
SIP and RTP security is server dependent and in order to configure user must use the web option Servers
(reference 0).
5.9.1 Certificates
The certificates list contains the list of loaded certificates for the system. Using the left column check mark
it is possible to check and delete certificates. To import a new certificate use the mouse “select file” and
browse to the selected file. When file is selected, use the “Load” bottom to load the certificate.
The certificate format supported is DER encoded binary X.509 (.cer).

By enabling Use Only Trusted Certificates, the certificates the base will receive from the server must be
valid and loaded into the system. If no valid matching certificate is found during the TLS connection
establishment, the connection will fail. When Use Only Trusted Certificates is disabled, all certificates
received from the server will be accepted.

5.9.2 SIP Client Certificates
To be able to establish a TLS connection in scenarios where the server requests a client certificate, a
certificate/key pair must be loaded into the base. This is currently supported only for SIP.
To load a client certificate/key pair, both files must be selected at the same time, and it is done by pressing
“select files” under “Import SIP Client Certificate and Key Pair” and then select the certificate file as well as
the key file at the same time. Afterwards, press load.
The certificate must be provided as a DER encoded binary X.509 (.cer) file, and the key must be provided as
a binary PKCS#8 file.

6 Functionality Overview
So far we have setup our BT Business DECT system. Next, in this chapter we list what features and
functionalities are available in the system. The BT Business DECT system supports all traditional and
advanced features of most telephony networks. In addition, 3rd party components handle features like
voice mail, call diversion, conference calls, etc. A brief description of BT Business DECT network
functionalities are:
•
Outgoing/incoming voice call management: The BT Business DECT system can provide multiple priority
user classes. Further, up to 3 repeaters can be linked to a Base-station.
•
Internal handover: User locations are reported to SIP Server in order to provide differentiated services
and tariff management. Within a DECT traffic area, established calls can seamlessly be handover
between Base-stations using connection handover procedures.
•
Security: The Fijowave BT Business DECT system also supports robust security functionalities for Basestations. Most security2 functionality is intrinsically woven into the BT Business DECT network structure
so that network connections can be encrypted and terminal authentication can be performed.
