Introduction
General
This manual covers the installation, maintenance and programming of an INDeX
Cordless Subscriber Line Cassette (CSLC) DECT system operating with software
Level 2.2+. It is intended for use by installers and maintainers who have successfully
completed an appropriate INDeX DECT training course.
The CSLC provides digital connection directly into the INDeX and provides the
system with integrated support for cordless handsets. The CSLC is both DECT and
GAP compatible

There are two variants of CSLC cassette. The CSLC 8 supports up to 8 base
stations and 64 handsets. The CSLC 16 supports up to 16 base stations and 128
handsets. Each base station can handle up to 4 simultaneous calls. Repeater base
stations can be used to extend the range of system coverage.
Only one CSLC cassette can be installed in an INDeX system and both cassettes
handle a maximum of 32 simultaneous calls
INDeX DECT conforms to the DECT Generic Access Profile (GAP) requirements.
This allows other GAP handsets to be used on the system (only INDeX handsets
can utilize the full feature set of INDeX). It also allows the INDeX DECT handsets to
be used on other GAP compatible DECT systems

DECT in Summary
DECT (Digital Enhanced Cordless Technology*) uses cellular radio methods to
handle multiple handsets on the same system at the same time. It is designed for
high density local area usage
The DECT system uses the frequency band of 1.88GHz to 1.9GHz. It employs
FDMA (Frequency Division Multiple Access) to divide the band into 10 separate
carrier frequencies. TDMA (Time Division Multiple Access ) further sub-divides each
carrier frequency into 24 time slots. Twelve slots are used for send and 12 for
receive, i.e. two slots are required per conversation on the carrier frequency. This is
called TDD (Time Division Duplex). The combination of a frequency and a timeslot
pair is called a channel and equates to one active call (when a handset is idle is
does not use a channel).

Timeslots
Adjacent
channels not
used
The pair of channels used by
a call is always 12 timeslots
apart (5ms)
Alternat
e
timeslots not
used
The above method gives 120 call channels available to a DECT system (10 x 24
channels, 2 channels per call).
During a conversation, a handset continuously compares the speech quality
obtained in its time slot to that in the same time slot on another carrier frequency. If
the current signal falls below acceptable limits and the other band is better, the
handset will change over to that band
DECT systems use DCS/DCA (Dynamic Channel Selection/Allocation) to resolve
availability of channels between handsets and base stations. These processes allow
a high density of handsets (on the same or different DECT systems) to operate in
the same area (provided sufficient base station channels are available)
Speech within DECT is digitised using ADPCM (Adaptive Differential Pulse Code
Modulation). Traditional PCM digitises speech by sampling at time intervals and
assigning a value to the amplitude at each time interval. This sequence of amplitude
values is then sent as a digital signal. In ADPCM information is only sent when their
is a difference in amplitude. This requires more processing electronics but allows
lower signal rates to be used for the same speech quality
*Originally DECT stood for "Digital European Cordless Telephony" but this was
changed as use of the standard spread beyond the European market

The INDeX DECT System Page 5
The INDeX DECT System
This sections gives a brief overview of the elements within the INDeX DECT system
CSLC
Each CSLC has a unique serial number that identifies the system to handsets. This
can be displayed through normal INDeX programming
The system configuration rules are as follows;
– Only one of the following cassettes (i.e. ALOG, CSLC, COMBO or BRIC) should
be used in a cabinet with a PSU4
– A maximum of 80 simultaneous ringing analogue extensions is supported per
cabinet (112 extensions if using ALOG 0/24)
– Cabinets fully equipped with analogue type cassettes are not recommended for
high traffic environments such as call centres
DECT Base Station (DBS)
These units support up to 4 simultaneous calls. There are two versions of the DBS
available; a standard DBS and an enhanced DBS.
A standard DBS uses even timeslots (see page 4)
An enhanced DBS uses odd time slots (see page 4)
Hence, by using a combination of standard and enhanced DBSs, higher density
DECT environments can be deployed. The recommended limit of DBSs in one area,
with a combination of standard and enhanced DBS, is seven (with ratios of 3:4 or
4:3). If all standard or all enhanced DBSs are used, then the recommended limit of
DBSs in one area is four (see page 9)
Only software PCS 3+ DBSs must be used with CSLC. Using standard telephony
cable base stations can be placed at up to 2km* from the CSLC. Base stations units
are designed for wall mounting
* Older style DBSs (supplied prior to autumn 2001) can only be placed at up to 1km
from the CSLC
Each base station is supplied with a 1.5m line cord for connection to a Slave Jack
Socket (not supplied)
– Size: 100mm wide x 100 high x 40mm deep (inc. wall mounting bracket)
Repeater
A Repeater works in conjunction with a Base Station to extend that Base Station's
area of coverage. A directional aerial can be added to increase the distance from the
associated Base Station (up to 1km line of sight)
Each Repeater is programmed to associate with a particular Base Station using a
Repeater Setup program. The Repeater can handle up to two simultaneous calls.
These calls are 'borrowed' from the Base Station. Hence, each call routed via the
Repeater reduces the number of calls that the Base Station can handle.
The Repeater does not need any wiring connection to the Base Station or CSLC.
The Repeater is designed for wall mounting and is supplied with a plug top PSU
fitted with 2 mtrs of cable
– Size: 100mm wide x 100 high x 40mm deep (inc. wall mounting bracket)
– Power: Power from a 230V, 50Hz plug top PSU, (9VDC, 300mA).

Introduction Page 7
Site Surveys
Introduction
The site survey is the most crucial part of any DECT installation. It is the
stage at which future success or failure of the installation will probably
occur.
Most issues of customer satisfaction will stem from the site survey and the
resultant positioning of the base stations
From the customer's point of view, two keys factors must be assessed:
– The area of coverage required:
– The number of simultaneous users within different areas:
Each base station can support 4 simultaneous calls. There is no problem
with having more than one base station in the same area.
During the site survey, you will be attempting to determine two factors to achieve the
customers requirements:
– The number of base stations required
– Their best positioning.
To fulfil this you need to obtain the following details:
– Building Measurements:
Accurate building plans are an essential aid to both the site survey and also
for later fault analysis
– Signal Strength: (RSSI - Radio Signal Strength Indication)
From potential base station positions, what is the range of the base station
signal at sufficient signal strength for reliable operation
– Speech Quality: (Q52)
Interference, weak signals and reflected signals lead to errors in the digital
voice signal that cannot be corrected. From potential base station position,
what is the range before the bit error rate becomes unacceptable
Installation Manual Page 7
INDeX CSLC 38DHB0002UKCA – Issue 8 (26/03/2002)

Page 8 - Site Surveys Base Station Coverage: In Theory
Base Station Coverage: In Theory
Given ideal open field conditions, the range between a handset and base station can
be up to 600 metres. Within a building, with signal strength being absorbed and
reflected signals giving increased error rates, the effective range is more realistically
between 50 metres and 150 metres.
A single base station's area of coverage is ΠxR2
R
With multiple base stations working together, areas of coverage intersect. Each
base station provides main coverage for an area 2xR2(thesquare areas below).
Naturally the base station signal still goes outside that area but normally calls are
handed over to the next base station at that stage
R R
R
In the worst case, call handover from one base station to another can take up to 10
seconds to complete. Thus for handset users moving at normal walking pace, base
station coverage areas need to overlap by at least 10 metres to ensure successful
call hand-over.
Maximum
overlaps
supported
All the above assumes a lot of things:
– That each base station has sufficient free channels. If there is no free channel
for a call handover, the handset will remain with its current base station until out
of range and the call is lost
– That the building structure is even such that the base station has the same
range in all directions
– That base stations only operate in 2-dimensions. In reality the signal forms a
sphere rather than a circle

Base Station Coverage: In Practice Page 9
Base Station Coverage: In Practice
In practice, no rules can be given for base station coverage. Coverage is affected by
many factors that are unique to each site. We can only guide you as to those things
that are likely to affect base station coverage
Obvious causes of signals problems:
– Metal surfaces, concrete thickness greater than one metre
Beware of:
– Windows with reflective film or specialised glass: (e.g. Pilkington 'K')
This type of glass, e.g. car windscreens, produces increased signal
reflection and reduces signal pass-through
– Wire Meshes and Grills with apertures of less than 4cm:
These block signals as effectively as continuous metal sheet
– Fire Doors:
These block the signals. In multi-occupancy building such as hotels the high
number of fire-doors may be a problem
– Stair Wells:
In modern office buildings, stair wells frequently combine concrete building
supports, fire doors and the intervening floor material, making them a special
problem
– Screened Rooms:
Typically found in offices involved with TV, video and radio production, but
also possible in computer centres
Base station overlap areas:
– In overlap areas, the signal from one base station is getting weak and so the
handset will start call handover to the next base station. However this
process can take up to 10 seconds. In overlap areas look out for items such
as closing doors that might suddenly block the already weak signal before
handover is completed
– To calculate the overlap required, based on the handset user's speed, allow
10 seconds to guarantee handover.
_ Remember that base stations located on different floors will add to the
number of overlaps
– Ideally base stations should be a minimum of 25 to 40 metres apart.
– The number of base station signals which can be monitored by DECT
Handsets is four.
– Do not put more than 3 DBSs in a cluster for the purpose of maximising call
capacity, i.e. within 25cm of each other
Opportunities to be aware of:
– In multi-storey buildings, if the building construction allows, a base station on
one floor can also serve the floor above or below

Page 10 - Site Surveys Using the Site Survey Kit
Using the Site Survey Kit
Guidance on where to start the survey and order in which to do a survey is difficult, each
case is unique and much relies on experience. Ensure that conditions are as near to normal
as possible, for example, in a warehouse when normal stocking conditions exist . If possible
do the survey on a normal working day when the building is in use. Check which areas you
can enter and when
The Survey Base Station
The Site Survey Base Station is a DECT Base Station that is able to transmit without
requiring a connected DCU. It is supplied with a suitable mains power supply unit.
As well as providing an RSSI/Q52 signal it can accept audio input via a 3.5mm
audio-jack input for a manual audio quality check.
Power Supply Input:
9VDC 150mA.

Audio Input
– Power Socket:
The Survey Base Station is supplied with a suitable power supply terminated
with an RJ11 connector. The connector uses Pin 6 (-ve) and Pin 5 (+ve) to
provide a 9V dc, 150mA supply
– Audio In Socket:
Standard 3.5 mono jack socket input.
– Subscribe Button:
If pressed and held for 3 seconds, puts the Survey Base Station in subscribe

Page 12 - Site Surveys Using the Site Survey Kit
Performing the Survey
Position the Survey Base Station in the potential position for a base station
installation. Connect the power supply. If possible also connect an audio source via
either the telephone line or audio jack sockets
1. With a subscribed handset on-hook, dial *99981* and press ✓
2. The handset display shows the signal quality
RPN: 01 <Base station number.
Q52: 52 <Speech quality.
RSSI: 64 <Signal strength.
3. Take the handset off-hook as this will ensure more realistic figures
– If you have connected an audio source you will hear it whilst off-hook. Use
this facility to check the audio quality (only one handset can be off-hook and
receive the audio source at any time)
4. Check the boundaries of the Survey Base Stations coverage where Q52 is
greater than 52 and RSSI is greater than 64. Mark this area on the building
plans and check that you have entered all areas that the base station might have
to server
5. Repeat this process with the Survey Base Station in a new location. Check that
the overlap between coverage areas is at least 10 metres
6. To return the handset to normal operation press and hold <until you hear a
short bleep
When the Site Survey is completed, a copy of the Base Station locations and the
plotted coverage must be left on the customers premises. This allows engineers in
the future to review the initial installation and physical layout of the site

Installing the CSLC Cassette
This section covers installation of a CSLC cassette
– Only 1 of the following cassette types (that covers ALOG, BRIC, COMBO
and CLSC cassettes) should be used in a cabinet with a PSU4
– A maximum of 80 simultaneous ringing analogue extensions is supported
per cabinet (112 extensions if using an ALOG 0/24 cassette)
– Cabinets fully equipped with ALOG cassettes are not recommended for hi
g
h
traffic environments such as call centres
To install a CSLC cassette :
1. Ensure that you have the correct cassette. The cassette label shows its type as
"CSLC8 " or "CSLC16 ".
2. Remove the screw at the top of the slot to be used. Insert the new cassette
3. After insertion of the cassette, there will be a delay, the length of which is
dependant upon the number of base stations, before the lamp status stabilizes.
Check which lamps come on.
– Green On/Red Off : Power supply to cassette okay
– Green Off : Swap cassette, if the problem persists, check the PSU/CPU
– Red On : Swap cassette, if the problem persists, check the PSU/CPU
– Red flashing : Check that the selected slot is not 'locked out'
(Administration/Linecard Information/Linecard)
4. Secure the cassette using its top tab (using the screw previously removed)
5. Connect the INDeX 32-pair cable to the cassette. Attach the cable's P-clip to the
appropriate point at the base of the cabinet for the cassette slot
6. Cable tie the cable to the base of the cassette.

Installing DECT Base Stations (DBS)
Correct positioning of Base Stations is vital to the performance of the whole
system. Before installing any DECT Base Station, ensure that you have
accurate plans for its location. If possible consult with the person who
performed the site survey.
Before installing any Base Station check the PCS levels shown on its labels. All the
Base Stations within a system must have the same PCS levels.
Note that software level PCS 3+ base stations can be installed up to 2km (1km for
older style units) from the CSLC.
CLSC to MDF Connections
The table below shows the connections from the CSLC cassette's 32-pair cable to
the MDF panel. It is recommended that you connect all 32 pairs even if the
installation does not require all 32. This allows for system expansion and
maintenance with the minimum of cable rewiring
Ensure that the cable and wires are clearly labelled at both ends.

Mounting the Base Station
Each Base Station is supplied with 1.5mtrs of cable for connection to the slave jack
socket (see page 3).
To mount a Base Station, perform the following:
1. Check the proposed position of the Base Station and ensure that there is a
minimum of 200mm's clearance on all sides of the Base Station
2. Use the Base Station Wall Mounting Bracket (see figure below) as a template to
mark the required holes. Ensure that the Base Station is level. Drill and insert
the wall fixings for the No. 6 round-head screws.
3. Run the Base Station line cord through the access hole before fixing the bracket
to the wall with the two No. 6 round head screws
4. Push the Base Station line cord into it's socket on the Base Station
5. Slide the Base Station onto the mounting bracket (a firm push is required to slide
the Base Station lugs over the pins on the wall mounting bracket)

Configuring the Base Stations
For the system to function correctly, it must measure the cable delay on signals to
and from each Base Station. Note that whilst this process is being performed the
system cannot handle calls. See "Base Station Cable Measurement" on page 17

Base Station Cable Measurement Page 17
Base Station Cable Measurement
The cable distance between the Control Unit and the Base Stations introduce signal

114). The Type setting for these user numbers must be set as Mobile
Note: Although up to 128 numbers can be allocated, the maximum number of
simultaneous calls on the CSLC is 32
These user numbers are then used as the directory numbers for any DECT
handsets registered on the INDeX.
To register a handset you must enter it's serial number. The serial number consists
of a five digit handset type number followed by a unique seven digit handset
number. On INDeX DECT handsets the serial number is printed on a label covered
by the handset battery

Page 20 - Installation Mobile Twin Numbers
Mobile Twin Numbers
The INDeX provides a Mobile Twin Number option for users. This option allows the
directory number of a DECT handset to be associated with the directory number of
another terminal (e.g. a user's desk telephone) and provides tight feature integration
The use of the Mobile Twin Number option requires entry of a Mobile numbers
switch licence on the INDeX
When used, having a mobile twin number has the following effects:
– Calls to the fixed terminal also cause the DECT handset to ring
– If either the fixed terminal or DECT handset are busy callers receive busy tone
(or follow the fixed terminal's divert on busy if set)
– Feature transparency, i.e. Messages/Call Backs/Camp-ons/Voice Mail/etc.
To enable mobile twin number use :
1. From the Main Menu select System and then Switch Licences
2. Select Mobile numbers and enter the licence key
To associate a DECT handset with a fixed terminal :
1. From the Administration menu select User and enter the directory number of
the fixed extension
2. Select Extended functions
3. Select Mobile twin number and enter the directory number of the DECT
handset (this automatically sets the Mobile twin number setting of the DECT
user directory number to the fixed terminal's directory number).
Hot Desking
INDeX Level 9.2+ provides a Hot Desk Mobile option. This option allows the LOG
ON prompt to be displayed on the 20DT

handset being used by eight Hot Desk users, allocate nine numbers
2. You can Multi-site Hot Desk provided that you repeat steps 1 to 3
above on each site. A Hot Desk user must use a separate 20DT on
each site and must log off on one site before logging on at another site
