INTRODUCTION TO CELLCOM 10
CELLCOM 10 BASIC DESCRIPTION
A CellCom 10 system
consists of three basic
elements: the base station,
wireless beltpacks, and
antennas.
CellCom 10 uniquely blends digital matrix technology with a locally distributed

countries. To this capability the system adds broad connectivity to party-line and
digital matrix intercom systems. With CellCom 10, beltpack-to-beltpack and
small-group communication is finally possible within a wireless system.
CellCom 10 may be used stand-alone or connected with party-line and/or digital
matrix intercom systems. These systems are typically used to coordinate the
actions of production staff in television broadcast, live theatre and performance,
event production, industrial, and government/aerospace applications.

Figure 1: A CellCom 10 Base Station, Beltpack, and Transceiver/Antenna
The CellCom 10 system consists of three elements:
• Wireless beltpacks,
• A base station that provides routing of communications to and from those
beltpacks, and
• Transceiver/antennas that can be located at intervals remotely from the base
station, providing customized coverage areas where the beltpacks function.

In addition, up to six wired full-duplex communications channels, plus program
in and stage-announce out, can all be connected and used simultaneously.
FEATURES
The CellCom 10 base
station functions as a
full-duplex digital matrix
switcher and router for voice
communications.
CellCom 10 brings the power of matrix communications to a wireless system,
blended with the coverage flexibility of a local cellular matrix. Features of
CellCom 10 include:
• Ten wireless beltpacks in 1 RU.
• Point-to-point and small group wireless communications.
• Up to six communications routes per beltpack.
• Custom coverage zones with up to ten remote transceiver antennas.
• Transceiver/antennas can be located up to 1,000 meters (3,200 feet) from the
base.
• Five-character labels for each beltpack and connector.
• Customize, name, and assign groups.
• Two party-line and four 4-wire connectors.
• Operates in 1.9 Ghz—above television and other wireless communications.
• License-free in countries accepting the DECT standard.
• Frequency-hopping DECT technology automatically finds clear spectrum.
• Base functions like a digital matrix; each beltpack has a “virtual port” timeslot.
Each transceiver/antenna
can support
communications with up to
five CellCom 10 wireless
beltpacks operating within
its coverage zone.
• Secure system—beltpacks are registered to a particular base and can frequency
hop.
• Two bases can be connected for a 20-beltpack system.
CELLCOM 10 THEORY OF OPERATION
CellCom 10 is quite different from other wireless intercom systems. Wireless
intercoms typically pair individual beltpack transmitters with individual
base-station receivers on the same frequencies, with the resulting signals mixed
and re-transmitted by the base to common receiver boards in the beltpacks –
achieving a wireless party-line.
The CellCom 10 base station functions as a full-duplex digital matrix switcher
and router for voice communications. Within the base, time slots are allocated to
each of the up to 10 wireless beltpacks, each of the full-duplex party-line and
4-wire connectors on the rear panel, the program input / stage-announce output,
and the front-panel intercom headset connector. This technology gives the
advantage of multiple point-to-point and small-group conversations being
possible simultaneously within the system.
Audio is sampled from each of the headset microphones, is processed and
combined as needed in the CellCom 10 base, and is then sent to each of the
beltpacks and wired connectors in turn. The wireless beltpacks in effect each have
1-2
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
a “virtual port,” as their data and digital audio is sent to and from each beltpack
in a particular time slot.
Each of these beltpacks and wired connections can be named (labeled) with a
unique 5-character alphanumeric designation, and these individual connections
can be combined into groups. All of the rear-panel wired communications
connections can also be labeled. This programming is done via menus within the
base station, and is stored in non-volatile memory.
Figure 2: A CellCom 10 Digital Communication System
Each beltpack has a unique “ID” which is registered with the base station and
assigned to a particular time slot. When the base station is turned on and
communicating via its remoted transceiver/antennas, the wireless beltpacks
immediately receive all of their “identity” and communications routing
information from the transmissions from the base – acting as specialized portable
communications terminals. Changes made to the communications routing on
the base are transferred to the beltpacks, so another source can be added to a
group or a talk/listen button on a beltpack can be reassigned in real time.
The wireless link between the base station and the beltpacks is accomplished by
transceiver/antennas that transmit and receive digital data and audio within a
circular coverage area with a maximum radius of 250 meters (about 800 feet)
under ideal conditions, but typically somewhat less depending on location and
obstructions. The base will support up to 10 of these transceiver/antennas, which
can be located throughout a production area to provide seamless coverage for the
wireless beltpacks.
It is also possible to remote one or more of these coverage zones independent of
the others. Transceiver/antennas, which connect with the base station (or via the
antenna splitter to the base) via 4-pair CAT-5 cable, can be positioned up to
1,000 meters (3,200 feet) from the base.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
1-3
Each transceiver/antenna can support communications with up to five CellCom
10 wireless beltpacks operating within its coverage zone. As the beltpack user
walks among the coverage zones created by overlapping the coverage of multiple
transceiver/antennas, the communication between that beltpack and the base is
“handed off ” to the next transceiver/antenna, without interruption.
If more than five CellCom 10 beltpacks will be operating in a certain coverage
zone, a second transceiver/antenna will be co-located with the first – one per
every five beltpacks working in the particular zone. The theoretical maximum
number of CellCom 10 beltpacks able to be supported in one zone is 50, and the
practical number is between 30 to 35.
The transmissions between the wireless beltpacks and the transceiver/antennas
are done using a customized application of the DECT protocol, operating in the
1.92 to 1.93 GHz band. CellCom 10 can be used without regard to existing
analog and digital UHF television transmissions, wireless mics and in-ear
monitors, and other wireless intercom. Transmissions are digital, and the
technology automatically seeks clear and unused “channels” within the overall
bandwidth allotted to the CellCom 10 system, changing as required by the
immediate circumstances.
Along with the digital nature of the transmission and the random changing of
channels, the unique ID of the beltpack is only registered to the particular
CellCom 10 base. Its transmission is only available to that base, and other
CellCom 10 systems being used in the same vicinity will not “see” it. Therefore,
though the system is not technically “encrypted”, it is virtually impossible to
capture and decipher these transmissions.
CellCom 10 wireless beltpacks can be added to the base rather simply, up to the
maximum of 10 per base. Registration is available through the a software utility,
and a 3.5 mm TRS jack on the beltpack accesses its digital ID. If an existing
beltpack in a system is lost or destroyed, a new unit can be registered in its place;
it will then take on the identity and communications routes of its predecessor.
The CellCom 10 base station also has a variety of connections for adding wired
party-line, digital matrix, and other communications. Two channels of party-line
and 4-channels of 4-wire / digital matrix can be connected via rear-panel
connectors. Each of these may be accessed individually by the wireless beltpacks,
or they may be grouped together in any way desired. Just like the beltpacks, each
of these full-duplex connectors has its own time slot and can be labeled. In
addition, a line-level program input and a line-level stage-announce / paging
output with associated relay is also provided.
DECT TRANSMISSION THEORY
Different that typical FM wireless communications systems, where each
transmitter has a corresponding receiver and is set to a particular frequency (even
in frequency-agile systems), CellCom 10 automatically seeks its own clear
frequencies. CellCom 10 operates in a different frequency band than wireless
microphones, in-ear monitors, and wireless intercoms, and its dynamic channel
selection and allocation capability means that the system does its own frequency
coordination continually while in use. DECT systems in general, and the
1-4
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
CellCom 10 digital wireless intercom in particular, do not require the frequency
coordination and the intensity of frequency planning that is necessary for FM
systems. Details of the technology are below.
CellCom 10 is based on a specialized application of the DECT (Digital
Enhanced Cordless Telecommunications) standard, which was originally
developed in Europe in the beginning of the 1990’s. It is an open standard for
site-specific radio access in the 1.88 to 1.90 GHz band (enhanced bands up to
1.93 GHz are included), allowing manufacturers to design compliant
technologies that can coexist in a user location and be used without interference
in adjacent locations.
In DECT terminology, the beltpack is called the Portable Part (PP) and the
transceiver/antenna is called the Fixed Part (FP). In essence, this means that the
transceiver/antenna stays in one place, while the beltpacks move with their users.
Each of these units has its own role. The FP creates the coverage zone for the PP,
and the portable part is the user interface, and also takes the initiative in signaling
the fixed part that it is in the coverage zone and seeking to establish and keep a
communications link. CellCom 10 and other DECT-based systems have
multiple fixed parts and portable parts.
DECT uses a Multi-Carrier (MC), Time Division Multiple Access (TDMA),
Time Division Duplex (TDD) radio-access methodology, and combines that
with a continuous Dynamic Channel Selection and Allocation capability.
Basically, it divides up the allocated 20 MHz of spectrum into bands and
channels, uses a fast time clock to sort out the various communications by
assigning each a time slot, and further dividing the time to allow two-way (full
duplex) conversations. To deal with potential interference and conflicts between
these different communications, the technology continually scans for open and
used channels, selecting the best one at any given time that won’t interfere with
other channels already in use.
The result of combining all of these technologies into DECT is that
high-capacity, high-density communications networks can be assembled at a
local level, and can function well even in environments with much RF “traffic.”
DECT is very efficient in finding and using open frequencies without
interference, all without active effort from the user. The fact that these systems
are localized, relatively low-power, and rely on distributed transceivers
throughout the desired coverage area, lead to the term “pico-cellular systems” –
or very small cellular systems.
The 20 MHz spectrum used in a DECT system is divided into 10 carrier
frequencies, which is the multi-carrier portion of the technology. The actual
bandwidth of each carrier is 1.728 MHz. Time, in the form of TDMA, is divided
into time frames that are accessed every 10 milliseconds, each containing 24 time
slots into which a single audio stream may be inserted. In typical consumer
DECT with its more limited audio bandwidth, two time slots are required for a
duplex conversation – one for talk and one for listen.
The special application of CellCom 10 with its better audio bandwidth gives two
time slots for each audio stream (user’s voice), so a full-duplex conversation
requires a total of four time slots. CellCom 10 uses a 2 Mb/s (two megabits per
second) data stream from the base station transceiver ports.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
1-5
Doing the math in the case of FreeSpeak Lite, a transceiver/antenna in a given
location selects a particular unused carrier frequency, and uses four time slots for
each full-duplex conversation with a CellCom 10 beltpack. Combined, the five
beltpacks that this transceiver/antenna can support use 20 of the 24 available
time slots (5 times 4). The remaining 4 timeslots are used to support the
recognition and handoff of other beltpacks as they move around and through this
coverage zone, and other related functions.
To support up to 10 beltpacks in a given location, for example, two
transceiver/antennas are placed to operate side by side using different clear carrier
frequencies. Given that these are relatively short-range, localized signals, a carrier
frequency that is being used in one physical location is likely to be clear again in
a nearby location – even within the same overall system installation.
A theoretical maximum of 50 CellCom 10 beltpacks can be used within a given
coverage zone, if 10 transceiver/antennas are co-located together. The practical
limit within a particular zone is in the range of 30 to 35 beltpacks in one zone.
The CellCom 10 transceiver/antennas, via the base station, are continuously
transmitting status and identity information on particular DECT carrier
frequencies, and the CellCom 10 beltpacks are able to receive and analyze that
information. The beltpacks put out a “pulse” at regular intervals to signal their
presence and ID. Through this interchange, the system will determine whether
the beltpack is registered to the base station (and through the base station to the
local transceiver/antenna) and is able to establish a connection.
This method of positive identification that a beltpack “belongs” to a system has
practical benefits in preventing interference or eavesdropping. For example, a
CellCom 10 beltpack whose unique ID is not registered with the particular base
will not be able to establish a communication link with that base. This means
that users of two different CellCom 10 systems that happen to be operating in
the same location – such as a large production event – will not accidentally or
otherwise connect with each others’ systems.
Since the beltpack user is continually moving, often through different coverage
zones created by multiple transceiver/antennas connected with the base station, it
must have a way to measure the strength of the signal connection, and to
establish a connection with the transceiver/antenna offering the highest signal
level. A protocol called RSSI (Received Signal Strength Indication) tells the
beltpack which available signal is both strongest and available to establish a
connection, as it scans through all the available possibilities.
For example, as a beltpack user passes from one coverage zone to another, it is
detecting the signal strength of both transceiver/antennas. Say that an adjacent
transceiver/antenna zone has less than five beltpacks currently connected through
it, so is available for another beltpack. Its signal strength is stronger that the
moving beltpack’s current connection with the other transceiver/antenna by a
threshold amount. In this circumstance, the beltpack will transfer its connection
to the new transceiver/antenna – in a “make before break” type of connection.
CellCom 10 and other DECT devices also provide security to communications
in several ways. First, the unique ID of a beltpack is registered with the base
station, and it must be recognized and authorized before a communications link
1-6
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
is authorized. Second, the transmission is digital, and does have a ciphering-type
encryption incorporated in the protocol to prevent eavesdropping. Third, the
dynamic changing of carriers and use of time slots means that a particular
conversation cannot be located or locked onto in any meaningful fashion.

THE CELLCOM 10 BASE STATION
BASE STATION (CEL-BASE)
The CellCom 10 (CEL-BASE) base station provides all of the intelligence and
signal routing for the CellCom 10 digital wireless intercom system. The base
station is effectively a full-duplex digital matrix communications system, with
virtual “ports” for the wireless beltpacks rather than physical ports.
In its memory, the base station contains all of the labels and communications
paths assigned to each CEL-BP beltpack, and this information is sent to the
beltpacks via the CEL-TA transceiver/antennas as soon as they are switched on
and recognized by the base. Through the front-panel display and controls, all
system programming is accomplished.
The base station also functions as the interface between wired and wireless
communication devices. The two party-line intercom connectors, four 4-wire
connectors, and program input/stage-announce output each have their own
full-duplex time slot. They can be labeled, added to communication groups, and
assigned to beltpacks as desired.

2 Channel A Talk Switch and Light/Listen Level Knob
The channel A talk switch and associated light, and listen level knob, allow
full-duplex conversations with any CellCom 10 wireless beltpacks or other
communications systems wired to the rear of the base station to which the
onboard Channel A has been assigned. Assignments are done via the front-panel
programming.
The talk switch is momentary/latching, such that pressing it and holding down
will create a talk path that ends when the user releases the switch, while quickly
tapping it will latch the talk, and a second tap will release it. The LED lights red
when a talk is active.
Turning the listen level knob clockwise will allow the user to hear the other
party’s voice, increasing the level to maximum when fully clockwise.
3 A/B Call Switch (Reserved for Future Use)
The A/B call switch does not function. It is reserved for future use.
4 Channel B Talk Switch and Light/Listen Level Knob
The channel B talk switch and associated light, and listen level knob, function
the same as the controls for Channel A.
5 Enable Switch and Lights for Channels A and B
The channel A and channel B enable switches and associated lights activate the
connection on the rear-panel to party-line intercom channels A and B. Activating
one or both of these switches makes duplex communications between the
wireless beltpacks and the wired party-line intercom occur. These switches may
be “locked” via the front-panel SYSTEM programming menu so that they may
not be disengaged accidentally.
6 Enable Switch and Light for Program Audio
This latching switch makes any program audio signal that enters via the
rear-panel line-level 3-pin XLR connector available to be assigned to wireless
beltpacks, either separately or mixed with communications groups. This switch
may be “locked” via the front-panel SYSTEM programming menu so that it may
not be disengaged accidentally.
7 Wireless Beltpack Light Display
These green LEDs, one for each of the ten CEL-BP wireless beltpacks that the
base will support, light when a beltpack is on and connected with the system. For
example, the beltpack that is registered with the base in the BPK03 time slot will
light the LED under number 3 when turned on.

8 Display Screen
The display screen shows all of the menus and programming options that are
available within the CellCom 10 system. The user can select a particular beltpack
and view all of its current talk/listen assignments, or see all of the current
members of a particular group. Via the screen and rotary encoder, labels
(5-character user names) can be created and/or changed, new members assigned
to groups, input and output levels adjusted, and so on.
9 Scroll/Enter Knob
The scroll/enter knob is used to scroll through the various menu options within
the CellCom 10 base, in order to discover specific information regarding users or
to program communications routes and groups. Turning the knob clockwise
scrolls display items toward the right, and turning the knob counterclockwise
scrolls display items toward the left.
When a desired menu item is highlighted, pushing the scroll/enter knob inward
will select that item. The lists of available beltpacks and groups typically span two
or more screens, so when the highlight is at the leftmost or rightmost part of the
screen and the user continues to turn the rotary encoder in that direction, the
display will jump to the next screen selections [Example: in the beltpack sections,
the first screen shows beltpacks 1 through 5, and the second shows 6 through
10.]. The “BACK” menu button can only be reached by turning the scroll/enter
knob clockwise.

IEC Power Connector
The 3-conductor AC power connector and universal power supply accepts
voltages from 90 to 250 volts, at 50/60 Hz. Power consumption is 80 watts.
2 Party Line Channel A Connectors
This pair of female and male 3-pin XLR connectors joins a channel of party-line
intercom to the CellCom 10 base station, allowing communication between the
wired system and CellCom 10 wireless beltpacks. Input and Output level control
is set via the front-panel display programming.
The second connector is a loop-through, so that the party-line connection may
be continued to another CellCom 10 base station or to another party-line
beltpack or station. This connector auto-detects a connection with a powered
party-line channel (30-VDC on Pin 2), and the base’s internal 200-ohm
party-line termination and DC voltage to power PL beltpacks is not activated.
Alternatively, when a wired, unpowered party-line beltpack (up to four) is
connected to PL CH-A with standard two-conductor shielded microphone cable,
the base station engages the 200-ohm termination and supplies 24-VDC to the
beltpack(s) – allowing them to operate and communicate with the wireless
beltpacks in the system.
3 Party Line Channel B Connectors
These connectors are the same as those for PL CH-A.
4 Program Input Connector
This female 3-pin XLR connector accepts a line-level audio signal from an
outside source such as a mixing console or audio player. It is transformer-isolated.
Level adjustment is done via the front-panel display programming. The program
input shares a time slot with the stage announce output, described below.
5 Stage Announce Output Connector
This male 3-pin XLR connector allows a line-level audio signal, typically a voice
from a wireless beltpack user, to be sent to a paging system or other audio system.
It is transformer-isolated. Level adjustment is done via the front-panel display
programming. One beltpack at a time can access this output, and it must be
programmed to a CEL-BP. It is activated by pushing the talk on the beltpack
rotary encoder to which the SA Output is assigned.
6 Stage Announce Relay
This DB-9 male connector provides a relay closure that is triggered
simultaneously with the SA Output. The relay may be used to open an audio
pathway for the signal from the SA Output, or could also be used to activate a
2-4
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
light or lock or some other device. The relay may be wired for normally closed or
normally open operation, and the signal appears on pins 1 & 6 or 2 & 6. It is
rated to a maximum of 30-VDC at 1 amp.
7 4-Wire Matrix Ports
These four RJ-45 connectors can connect four full-duplex (input pair and output
pair) audio connections from a 4-wire communications device, digital matrix
intercom, or similar – making them available to the wireless beltpacks. The first
two RJ-45’s have both audio and data connections, to be used in the future for
intelligent communications routing. The second two have audio connections
only. Each of these connectors has its own time slot, and can be addressed
separately from a beltpack, or combined with other beltpacks and rear-panel
connectors in a group. Level adjustment is done via the front-panel display
programming.
8 Base Loop Connector
The base loop RJ-45 connector is used to join two CellCom 10 base stations to
form one larger – up to 20 wireless beltpacks – communications system. It passes
the digital audio signals and time slot data between the two bases. Point-to-point
communication is possible from a CEL-BP wireless beltpack assigned to one base
to a wireless beltpack assigned to the other base.
9 LAN Connector
This RJ-45 connector is used for rapid system software upgrades, and in the
future will be used for intelligent connection with the Clear-Com Eclipse digital
matrix systems, and for remote access to the CellCom 10 base. It is essentially a
10BaseT Ethernet port.
10 PC Connector
This female DB-9 is used for firmware updates and monitoring of the system
configuration. It functions as a serial port.
11 Transceiver Connectors
These two RJ-45 connectors are used to communicate with the remote CEL-TA
transceiver/antennas, which create the wireless coverage areas that connect the
CEL-BP wireless beltpacks to the base station. In the basic CellCom 10 system,
these transceiver connectors together support up to four CEL-TA
transceiver/antennas – with the addition of the CEL-SP antenna splitter to make
sufficient ports for each of the antennas. All CEL-TA transceiver/antennas must
be connected to a CEL-BASE transceiver port (or to it via a CEL-SP antenna
splitter) as a “home run.” The addition of the optional CEL-EXP antenna
expansion board (connects internally within the base station) supports six more
transceiver/antennas, for a maximum of ten.

CONNECTING THE BASE STATION TO PARTY-LINE
INTERCOM SYSTEMS
Up to two channels of party-line intercom can be connected to the FreeSpeak
LiteCellCom 10 base. The descriptions below will discuss connections with
Clear-Com and compatible party-line, RTS party-line, the ability of CellCom 10
to power a few Clear-Com beltpacks by itself, and the front-panel settings
associated with these party-line connections.
Using the front-panel display and rotary encoder, the user may go into the
PORTS menu, select the desired party-line channel, and create a five-character
alphanumeric label for it. This is the label that would then appear on any
CellCom 10 wireless beltpacks to which that party-line connection was assigned
for communications. In the GROUPS menu, the party-line connection can be
assigned as a member of any of the groups, as desired.
CLEAR-COM AND COMPATIBLE PARTY-LINE
Clear-Com and Clear-Com-compatible wired party-line intercoms connect to
the PL CH-A and PL CH-B connectors in a similar manner to connecting
beltpacks or remote stations to the intercom line. Typically that wired intercom
connection would have a 30-VDC current on Pin 2, coming from a main station
or an intercom power supply. The second connector in the pair may be used as a
loop-through to go to other wired party-line stations or beltpacks, or to a second
CellCom 10 base station.
When the CellCom 10 base detects a wired party-line being connected with
30-VDC on Pin 2, it automatically disables the 200-ohm termination on that
connector, and also does not enable the 24-VDC power supply that the CellCom
10 base station supplies to the connector to support a handful of
locally-connected wired party-line beltpacks. The base station then appears to the
wired party-line system as a remote station.
Caution! Make sure that the CellCom 10 base station is disconnected (either
physically or via the enable buttons) from the party-line system when you are turning
it on, and/or that no speaker stations are on and no one is wearing headsets connected
to the party-line system. During the power-up cycle, for the 10 or so seconds until the
base reaches its programming screen, a loud and high-pitched series of noises may be
injected onto the party-line. The party-line system can be powered up after the
CellCom 10 base has stabilized, or the connectors can then be plugged into the
CellCom 10 base; this noise will not happen under those conditions.
CONNECTING CLEAR-COM PARTY-LINE BELTPACKS DIRECTLY TO
FREESPEAK LITE
PL CH-A and PL CH-B have the ability to directly support up to four
Clear-Com RS-501 or RS-601 party-line beltpacks each, without any other
connection to a wired party-line system. This feature gives the convenience of
being able to add a few wired beltpacks when needed to a CellCom 10
installation.
2-6
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
Connect a standard two-conductor shielded microphone cable to the PL CH-A
connector, and then connect it to a Clear-Com single-channel party-line
beltpack. The base will detect that the beltpack has been connected, and will
enable the required 200-ohm termination, and will supply 24-VDC to Pin 2 to
power the beltpack(s).
You can daisy-chain up to four beltpacks, or use an intercom XLR splitter at the
base to feed mic cables connected to the individual beltpacks. Because it is a
24-volt rather than a 30-volt current, the maximum length of cable that can be
connected (the sum of all of the runs) will be shorter than what is expected with
the standard party-line voltage. Do the same with PL CH-B to support an
additional four beltpacks.
CONNECTING TO AN RTS™ WIRED BELTPACK
RTS beltpacks place two channels of party-line intercom on a single 3-pin XLR
connector. Pin 1 is Ground, Pin 2 contains one channel of signal plus 30-VDC,
and Pin 3 contains the other channel of signal. With the following modification,
CellCom 10 will connect to those two communications channels.
Because each of the connectors on the rear-panel of the CellCom 10 base station
is separate and has its own time slot (similar to the ports in a digital matrix
intercom system), an external splitter cable must be used to split the two
channels of party-line on the single RTS 3-pin XLR cable into two XLR
connectors – each carrying one of the channels.
Use an XLR-3F connector for the connection with the intercom line from the
RTS-TW system. Using two lengths of shielded two-wire (microphone) cable,
split into two XLR-3M connectors.
For the connector that will deliver channel 1 of the RTS communication, pin 1
(common) of the XLR-3F will connect to pin 1 of the XLR-3 M connector. Pin
2 (audio 1 plus DC) of the XLR-3F will go to both pin 2 and pin 3 of the
XLR-3M. Thus it will have signal and DC appearing on both pins 2 and 3.
CellCom 10 will use the DC on pin 2 to deactivate the 200-ohm termination on
that connector, and will use the signal on pin 3 for the audio.
For the connector that will deliver channel 2 of RTS communication, connect
pin 1 (common) of the XLR-3F to pin 1, of the XLR-3M connector. Similarly,
connect pin 2 to pin 2, and pin 3 to pin 3 – so that the XLR-3M is identical to
the pin wiring of the XLR-3F. CellCom 10 will use the DC on pin 2 to
deactivate the 200-ohm termination on that connector, and will use the signal on
pin 3 for the audio.
FRONT-PANEL ADJUSTMENTS FOR PARTY-LINE CONNECTIONS
To connect the party-line channels to CellCom 10 and make the communication
available to the rest of the system, press the CH-A and/or CH-B Enable switches.
The LED will light, and the connection is made. To disconnect the party-line
connections, press these switches again. The switch may be “locked” in the
SYSTEM menu so that the party-lines may not be disconnected.

Because party-line intercom does not have global level control on a channel,
input and output level controls are provided via the front panel programming.
Scroll to PORTS on the main display screen and press the rotary encoder to
select. Scroll to 4-WIRE and press to select. Go to CALLS and press to select.
Doing so creates a route to the selected destination. If you save your changes, the
route will be reinstated at power up. You can also set this option to NONE.
Use the rotary encoder to adjust the numerical level – clockwise to increase the
level and counter-clockwise to decrease the level. Make the estimated changes in
level and press the rotary encoder to save the changes. Test the levels between the
party line and CellCom 10 beltpack, and make additional changes as needed.
When the levels are set as desired, press to select and the display will go to the
previous INPUT/OUTPUT screen. When both are adjusted, select BACK on
each screen until you return to the main screen.
CONNECTING THE BASE STATION TO 4-WIRE AND
DIGITAL MATRIX INTERCOM
Up to four channels of 4-wire/digital matrix intercom can be connected to the
CellCom 10 base. The descriptions below will discuss connections with
Clear-Com Matrix Plus digital matrix, Clear-Com Eclipse digital matrix, other
brands of digital matrix intercoms, other 4-wire audio devices, and the
front-panel settings associated with these 4-wire connections.
Using the front-panel display and rotary encoder, the user may go into the
PORTS menu,then scroll to 4-WIRE and press to select. Go to CALLS and press
the ENABLE button on the FreakSpeak Lite front panel. Doing so creates a
route to the selected destination. If you save your changes, the route will be
reinstated at power up. You can also set this option to NONE.
In the GROUPS menu, the 4-wire port can be assigned as a member of any of
the groups, as desired.
CONNECTING WITH CLEAR-COM MATRIX PLUS
The connection between a Matrix Plus digital intercom port and a CellCom 10
4-wire port is accomplished with a standard 4-pair CAT-5 data cable with RJ-45
connectors on both ends. In the current generation of FreeSpeak Lite, the audio
input and audio output pairs are all that will be used.
In the Matrix Plus PGM-WIN configuration software, set the matrix port that is
connected to the CEL-BASE base station 4-wire port to “4-Wire.” If you will be
putting the label of this CellCom 10 4-wire port onto more than one intercom
panel within the matrix system, and you want to allow any and all people who
have activated an talk/listen to that port to be able to hear each other as well as
hearing the person talking to them from the CellCom 10 wireless beltpack, also
check “Party-Line Enable” for that 4-Wire connection in the configuration
software.
Within the configuration software, the user can adjust the input and output level
for that port. Alternately, the input and output levels can be adjusted on the
CellCom 10 base for the particular 4-wire port, using the front-panel display.
2-8
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
Repeat the procedure for each CellCom 10 4-wire port that is connected with the
Matrix Plus system. Note that CellCom 10 does not currently generate a call
signal to the Matrix port.
CONNECTING WITH CLEAR-COM ECLIPSE DIGITAL MATRIX
Currently, the procedure to connect between a CellCom 10 4-wire port and the
Eclipse digital matrix is similar to that of Matrix Plus 3. An identical connection
is made with 4-pair CAT-5 cable between an Eclipse port and the CellCom 10
port.
Within the Eclipse configuration software, set the port to “4-Wire.” This will
allow intercom stations in the Eclipse system to converse with the CellCom 10
base and beltpacks. Because there is not a “Party-Line Enable” within Eclipse, if
several users of intercom stations connected with Eclipse need to hear each other
as well as the wireless CellCom 10 beltpack, another procedure will need to be
added. Within the configuration software, the user would create a new party-line
label, with members including the desired intercom stations and the particular
CellCom 10 4-wire port. That label would then be assigned to a key on each of
the intercom stations, allowing connection with the CellCom 10 4-wire port and
the other members of the new party-line.
Within the configuration software, the user can adjust the input and output level
for that port. Alternately, the input and output levels can be adjusted on the
CellCom 10 base for the particular 4-wire port, using the front-panel display.
Repeat the procedure for each CellCom 10 4-wire port that is connected with the
Eclipse system.
CONNECTING WITH OTHER DIGITAL MATRIX INTERCOM SYSTEMS
Because CellCom 10 features standard 4-wire ports, with an input pair and an
output pair, virtually any 4-wire signal can be connected with it. Make sure to
properly match the input and output pairs between the digital matrix port and
the CellCom 10 4-wire port (see diagram below).
The pinouts for the first two 4-wire ports contain both audio and data
connections, though the data connections are not currently used. Those pinouts
are shown in the following table.

The remaining two 4-wire connections are audio only, and the data connections
are unterminated.
Within the configuration software of the other digital intercom system, configure
its connected port to 4-wire or similar. Adjust the input and output levels either
at matrix side or within the CellCom 10 front-panel display for the particular
CellCom 10 4-wire port.
CONNECTING WITH OTHER 4-WIRE DEVICES
Various other 4-wire audio devices can be connected with FreeSpeak Lite. The
Clear-Com EF-1M 4-wire interface can be used to attach additional party-line
channels to FreeSpeak Lite, converting them from party-line on the wired side to
4-wire on the CellCom 10 side. The Clear-Com IF4-B interface can be used
similarly. The audio input side of the CellCom 10 4-wire connectors could be
used for additional program or other audio inputs that could then be accessed by
CellCom 10 beltpacks. The audio output side of the CellCom 10 4-wire
connectors could be used to route a CellCom 10 wireless beltpack user’s voice
out of the system for paging or other reasons, similar to the SA OUT connector.
When using the CellCom 10 4-wire ports in this way, make sure that proper
connections are made between CellCom 10 and the other device. Adjust the
input and/or output levels either at the 4-wire device or within the CellCom 10
front-panel display for that particular 4-wire port.
CONNECTING TO A PROGRAM AUDIO SOURCE
CellCom 10 can connect with a program audio source, making it accessible to be
assigned by itself to a communications path to one or more CEL-BP wireless
beltpacks, or to be added to a group with other communications and assigned to
beltpacks. Using the two separate rotary encoder volume controls on the
beltpack, the user could monitor the program on one control while talking and
listening on an intercom channel with the other.
The balanced female 3-pin XLR connector accepts a standard audio signal from a
mixing console or similar, with Pin 1 ground, Pin 2 audio hot (+), and Pin 3
audio cold (-).This connector is transformer-isolated.
To make the program input signal available to the system, the front-panel PRGM
Enable button must be pushed. The red LED above it will light, indicating that
it is now available. This front-panel switch may be “locked” to prevent accidental
disengagement, using the front panel display.
Using the front-panel display and rotary encoder, the user may select PORTS
and give the connector a five-character alphanumeric label. The user may assign
that program input by itself to a beltpack using the BELTPACKS menu, or using
the GROUPS menu may assign the program input to any group.
2-10
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
CONNECTING TO THE STAGE ANNOUNCE OUTPUT
The stage announce feature allows a CEL-BP wireless beltpack user to route their
voice to an external paging system or other audio destination by pressing one of
the rotary encoders to which the SA OUT connector is assigned. The adjacent
SA RELAY is simultaneously triggered. One beltpack user at a time may use this
feature, though the capability may be assigned to any or all of the wireless
beltpacks, as desired.
Connect a microphone cable to the male 3-pin XLR connector on the rear of the
CellCom 10 base station, and connect the other end to the external audio
system. When the output is activated, the beltpack user’s voice will be sent at
line-level to the audio system. The audio output ceases when the beltpack user
stops pressing the rotary encoder; it is good practice to make sure that any rotary
encoder to which the SA OUT is assigned is set to momentary/non-latching
mode.
The associated SA RELAY can be assigned to open an audio route for the paging
or announcement, or can be assigned to initiate any other event such as turning
on a light or activating a lock. It is rated at a maximum of 30-VDC at 1 amp.
The relay can be wired to be either normally open or normally closed, using the
following pinout information:

BASE STATION DATA CONNECTIONS
CONNECTING VIA THE SERIAL PORT
The PC serial port on the rear of the CellCom 10 base station is mainly used for
firmware version upgrades of the system. This procedure will rarely be done by
the user.
A specially wired cable is required for these updates, consisting of two 9-pin
D-type connectors for the PC and the CellCom 10 ends. On the CellCom 10
end, a male 9-pin D connector is used, and is wired as follows in relation to the
D connector pins on the PC end. Pin 2 goes to pin 3, pin 3 goes to pin 2, and
pin 5 goes to pin 5; in other words, the data Tx and Rx lines on pins 2 and 3 are
reversed. Those are the only wiring connections on the CellCom 10 end of the
cable.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
2-11
On the PC end, a female 9-pin D connector is used. Make sure that the data
connections of pin 2 to pin 3 and pin 3 to pin 2 are followed, and that pin 5 goes
through to pin 5. Then short pins 1, 4, 6, and 8 together on the PC end of the
cable. The cable will now be ready to use with the any upgrade files from the
factory.
CONNECTING VIA THE LAN PORT
The LAN port is mainly reserved for future use in FreeSpeak Lite. This
connection will be used for rapid firmware updates, as well as in the future for
system configuration and intelligent connection with the Eclipse digital matrix.

LINKING TWO BASE STATIONS TO FORM LARGER
SYSTEMS
Two CellCom 10 base stations may be joined via the rear-panel BASE LOOP
connection to create larger communications systems that will support up to 20
wireless beltpacks, plus all of the available rear-panel connectors on both bases.
The labels on each base are available to the other base, groups may be created and
assigned that contain beltpacks and rear-panel inputs from both bases, and
point-to-point conversations between beltpacks registered with the two different
bases are possible.
The one limitation to this expanded system is that the CEL-TA
transceiver/antennas connected to “Base #1” will only communicate with the
CEL-BP wireless beltpacks registered with “Base #1.” So some care will need to
be taken when assigning particular beltpacks to locations and users in the
production area, to most efficiently use the transceiver/antennas.
Use a specially wired four-pair CAT-5 data cable to connect the BASE LOOP
connectors on the two bases together. This cable must have a maximum length of 1
meter (3 feet). The pinouts of this cable are shown in the following table.

TRANSCEIVER/ANTENNA (CEL-TA) CONNECTIONS
CONNECTING ONE TRANSCEIVER/ANTENNA (CEL-TA) DIRECTLY TO A
TRANSCEIVER PORT
A CEL-TA transceiver/antenna connects to the transceiver port on the CellCom
10 base station using a standard 4-pair CAT-5 data cable with RJ-45 connectors.
It may be located up to 1,000 meters from the base station, creating a coverage
area for up to five CEL-BP wireless beltpacks in that location. The port is able to
provide the required power to the transceiver/antenna at a distance of up to 300
meters (approximately 900 feet); beyond that distance, the CEL-TA
transceiver/antenna must be locally powered via its in-line external universal
power supply.
To know that a CEL-TA transceiver/antenna is active, observe the green power
LED and the yellow signal LED on the face of the unit where the RJ-45
connector is connected. Both must be lit. Also, CEL-BP wireless beltpacks in the
vicinity of the active transceiver/antenna will be connected to the system and
their displays will show labels and other information.
Using both transceiver ports, a CEL-BASE base station may be connected with
up to two CEL-TA transceiver/antennas via a direct connection with the base.
For the best, most reliable coverage, it is advisable to use a minimum of two
transceiver/antennas in any installation, positioned in different locations in the
coverage area. When more CEL-TA’s are required to support a larger coverage
area or more wireless beltpacks, a CEL-SP antenna splitter will need to be
introduced between the base station and the transceiver/antennas.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
2-13
CONNECTING TRANSCEIVER/ANTENNAS WITH A SPLITTER (CEL-SP)
A splitter (CEL-SP) will connect up to five transceiver/antennas to one of the
transceiver ports on the CellCom 10 base station, creating up to 5 coverage zones
that can be overlapped to make large areas where CEL-BP wireless beltpacks can
have continuous coverage. The use of the splitter also extends the distance that
the CEL-TA transceiver antennas can be located from the base to beyond 1,000
meters (3,200 feet).
For example, a splitter can be used to connect to a CellCom 10 base that is
located in a production truck outside an arena or stadium, with a single CAT-5
cable going to the splitter which is then located just inside the stadium. From
that splitter, up to five CEL-TA transceiver/antennas are distributed throughout
the stadium to create wide coverage – each with a run of CAT-5 cable back to the
splitter. A similar arrangement may be used in a large theatre or performing arts
facility.
The connection between a transceiver port on the CellCom 10 base station and a
CEL-SP splitter is accomplished with standard 4-pair CAT-5 data cable with
RJ-45 connectors. It is connected to the port labeled MATRIX on the splitter.
This cable can be as long as 1,000 meters (3,200 feet). The splitter must be
locally powered via its DC IN connector, using the in-line external universal
power supply. The RJ-45 ports on the splitter labeled “1” through “5” are the
connections to the CEL-TA transceiver/antennas. Transceiver/antennas
connected to the splitter can be powered at a distance of up to 300 meters (900
feet); beyond that distance they will need to be locally powered.
The CEL-BASE CellCom 10 base station has internal processing to support up
to four CEL-TA transceiver antennas. In order to support up to the maximum of
ten that a base can handle, the optional CEL-EXP “daughter” circuit board must
be installed into the base station. This board enhances the capabilities of the two
transceiver ports. See the section on the CEL-EXP for more details.

THE CELLCOM 10 WIRELESS
BELTPACK
WIRELESS BELTPACK (CEL-BP)
The CEL-BP wireless beltpack gives the user simultaneous access to two channels
of talk/listen communication, with the ability to switch among three pairs of
communications routes/channels as desired. Any or all of these six routes (two
channels times three pairs) may be kept open during use. Listen levels may be
individually adjusted using the two push-to-talk rotary encoders, so that one
conversation can be monitored in the background while a primary conversation
is held.
The front-panel display contains the name (label) of the beltpack user, identifies
the two talk/listen labels currently selected by the user, and gives other
information such as signal strength and battery level. In the local programming
mode, it displays all of the menus and adjustments available. A 4-pin male
headset connector is provided for connection with a standard Clear-Com headset
or similar. The CellCom 10 beltpack will operate for up to 8 hours on four AA
alkaline or rechargeable NiMH batteries.

Pressing the top of the rotary encoder knob pushes it in momentarily, engaging
the “talk” for that channel of communication. The talk capability may be
momentary only, where the user’s voice is only sent to the listener as long as the
knob is pressed down. Alternatively, it may be latched, where a quick push will
latch it on “talk” until another quick push releases it.
2 Channel A and Channel B Level-Control Lights
A series of three level-control lights are arrayed beside each rotary encoder. The
first light is green, the second is yellow, and the third is red. With the level
control knob turned fully counterclockwise, only the green LED is lit. Turning
the knob clockwise, low audio level is heard in the headset. Turning the knob
more, both the green and yellow LED’s light, and higher audio level is heard.
This continues through the maximum audio level, indicated by only the red light
being lit.
3 Channel A and Channel B Talk/Listen Lights
On the opposite side of the rotary encoder, a green “listen” LED and a red “talk”
LED are side-by-side. When another beltpack user whose label is displayed (on
the beltpack LCD display) underneath the rotary encoder pushes their talk
button to initiate a conversation, the green LED begins to blink. When the local
beltpack user presses down the rotary encoder to activate a momentary or
latching talk, the green button lights steadily and the red talk button also lights.
The red talk button on the beltpack that initiates the conversation and flashes
until the person receiving the “call” presses their talk in order to answer.
4 Answer-Back Lights
The red and green lights in the front-center of the talk panel are used to indicate
that a user that is not on the beltpack’s presently selected communication routes
is trying to call and initiate a conversation. The green LED begins flashing when
a call is coming in. By pressing the larger center blue button on the front face of
the beltpack, the call is answered and the user can talk to the caller. The green
LED lights steadily and the red LED lights, until the conversation is ended by
again pushing the center button.

CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
3 Battery Recharger Connector
The CellCom 10 beltpack features an internal battery charger when the user
inserts four AA-format NiMH batteries to power the unit. The recharger circuit
includes a thermistor that senses the temperature of the battery pack to prevent
overcharging. To use this internal recharger, plug in the small barrel connector on
the supplied universal power supply into the beltpack connector, and then plug
the supply into the local AC current. It takes approximately 3 hours to recharge a
fully discharged set of batteries in the beltpack.
CellCom 10 beltpack usage time is dependent upon the batteries used. Some
batteries require more charge/discharge cycles than others to reach their rated
capacity.
Caution: Do not put battery packs containing alkaline batteries into a recharger, or
recharge them in the beltpack. Serious damage or injury could result.
BELTPACK TURN-ON SEQUENCE
After pressing the POWER button on the rear of the beltpack for approximately
three seconds, the top control panel LED’s will flash and the display will light.
The display will say “FreeSpeak Lite” and “Searching for Network.” It will briefly
say “Getting Roles”, and then will go to the main user screen.
The beltpack will always begin on Page 1, which has the first two
communications routes assigned to the beltpack. When programming
communications routes for the users in the system, it is best to put the most
commonly used ones on this page.
BELTPACK TURN-OFF SEQUENCE
To turn off the beltpack, press and hold the POWER button on the rear of the
beltpack for about three seconds. The main screen will close, followed by a screen
that says “FreeSpeak Lite” and “Shutting Down.” Since all of the routing and
“intelligence” of the beltpacks is in the base station, it will become available again
when the beltpack is turned on.
POWERING THE CELLCOM 10 BELTPACK
The supplied battery pack holds four AA-sized batteries. Standard AA alkaline
batteries will provide between 7 and 8 hours of typical use. The batteries
alternate in the battery case, with the spring on the negative end and the tab on
the positive end.
For best performance, use fresh alkaline batteries that have been properly stored
and kept away from excessive heat. As with all other battery-powered electronic
items, when the CellCom 10 beltpack is stored for extended periods of time,
remove the batteries to prevent damage from possible leakage of the alkaline cells.
WARNING: Make sure that CellCom 10 battery packs loaded with alkaline
batteries are not put into a battery charger, or that the internal beltpack charger is
used to attempt to charge them. Damage and possible injury will result.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
3-5
Rechargeable AA-size NiMH (nickel-metal hydride) batteries may be used with
the CellCom 10 beltpack. Select good quality batteries with high amperage
ratings for the best and longest performance. These batteries will last for many
charge cycles, and will power the beltpack for approximately 8 hours.
Note: CellCom 10 beltpack usage times are dependent upon the batteries used. Some
batteries require more charge/recharge cycles than others to reach their rated capacity.
The beltpack front-panel display has an icon that shows the battery condition. It
has five vertical lines to signify the remaining charge. When the icon has dropped
down to the last two lines, or if it drops quickly after being turned on after
previous use, it will be time in the next few minutes to recharge the batteries (if
rechargeable ones are being used) or replace them. The beltpack will turn off by
itself at low battery levels.
Within the menu structure of the beltpack, a low-battery alarm is available and
may be set. When activated and when the battery level is sufficiently low
(approximately 20 minutes of remaining battery life) the headset user will hear a
beep at intervals to indicate that the batteries must be replaced or recharged soon.
This setting is available under Alarm Options.
The CellCom 10 beltpack features an internal battery charger circuit, with
intelligent circuitry to prevent overcharging. It is powered via the pin connector
on the bottom of the beltpack, using the supplied universal power supply. A
thermistor (temperature-sensing device) measures the change in temperature of
the battery when charging, letting the circuit know when to cease charging the
batteries.
An optional sealed rechargeable battery pack is available for the CellCom 10
beltpack. It features high-amperage NiMH batteries. A companion 5-bay battery
charger unit for these batteries is also available from Clear-Com. (Available in
later 2004.)
ACCESSING THE TALK PATHS ON THE CELLCOM 10 BELTPACK
The CEL-BP beltpack can access up to three sets of two talk/listen paths, which
are assigned to the left and right rotary encoders. One set can be accessed at any
given moment, and the user can easily select the next set via the beltpack scroll
buttons. The assignments are done at the CellCom 10 base through the
front-panel display menus (see section on system programming).
When the CEL-BP beltpack is first turned on and connected with the base
station, the unit defaults to “page” 1 of the assignments to that beltpack. This
first set of talk/listen paths may immediately be accessed. To access one of the
two other sets that may be assigned to the beltpack, press the left or right scroll
buttons on the face of the beltpack.
The user will hear beeps in the headset, with the number of beeps heard
corresponding with the page number (3 beeps means the user is on page 3). Each
push of the button advances one page. The scroll buttons go through the list
continually, so scrolling either to left or right will access all “pages.” The display
will also highlight the particular page that is currently selected.
3-6
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
As soon as the page is reached, those talk/listen paths are accessible. Pushing one
or both rotary encoders will activate talks back to those conversations. Activated
talks and listens on the other pages will remain operationsal.The user may return
to the previous ones in the same manner, using the left and right scroll buttons.
SETTING AND ADJUSTING LISTEN LEVELS
Two stages of setting levels are available on the CellCom 10 beltpack. The first is
within the menu structure, and controls the global maximum level that may be
set. This option may be found under Audio Options/Headset Options/Master
Level. The user is presented with a bar graph on the display, and the level can be
adjusted up or down using the left and right scroll keys. Once the desired level is
reached, pressing the center ENTER button saves it and the display returns to
the preceding screen. Typically this level control will be set around 2/3 of
maximum.
The second stage of setting levels is done using the rotary encoders for the
individual talk/listen paths that are assigned to them. As the user is talking and
listening, turning these controls clockwise will increase the listen level for that
conversation to maximum, and turning them counterclockwise will decrease it to
minimum. As the user goes between the three “pages” of talk/listen assignments,
the listen levels for each of them are kept. For example, raising or lowering the
level on the left rotary encoder when on page 2 will not affect the level that was
set for that rotary encoder on page 1 or page 3.
The LED indicators above each of the rotary encoders give a visual
representation of the levels that have been selected at any given time. The set of
LED’s goes from green at the lowest listen level through yellow and to red at the
highest level. The absolute position of the rotary encoder has no bearing on the
level that is heard or that is indicated by the LED’s.
Turning counterclockwise will take the listen level to minimum, and only the
green LED will be lit; continuing to turn the encoder in that direction will have
no further effect. Similarly, turning the encoder clockwise until the red LED
alone is lit achieves the maximum audio level. The change in direction of the
turn is what brings about the level change.
USING THE BELTPACK ANSWER-BACK FUNCTIONS
The answer back feature on CellCom 10 has two basic functions. The first is to
provide a convenient way to answer a call from someone whose label is assigned
to your beltpack when the beltpack is not currently scrolled to that page. The
second is to allow a beltpack user in the system to call another beltpack that does
not have a reciprocal link back to the caller.
When a beltpack-to-beltpack or a group label is assigned to one of the three
pages on a beltpack, and the user currently is on another page, the caller who
pushes a talk to initiate a conversation will activate the answer-back function on
the called beltpack. The longer green LED in the top center section of the
beltpack will begin to flash, and the caller’s voice will be heard at whatever level
was set via the rotary encoder for that caller’s label.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM

This call may be answered in two ways. Pressing the larger blue center button on
the front of the beltpack will establish a return talk path to the calling beltpack;
this button can be pressed and held for momentary operation or tapped quickly
to latch. Alternately, the user can use the smaller blue scroll buttons on the face of
the beltpack to go to the page where the caller’s label is displayed. The flashing
green LED of the call then moves from the answer-back position to the particular
rotary encoder where that caller is assigned, and the rotary encoder may be used
as normal to establish a talk to the caller.
As an example, say that a director beltpack labeled DIR is trying to contact a
lighting director beltpack labeled LD. Each of them has the other’s label on page
1 of their beltpacks, but the LD is currently on page 3. When the DIR beltpack
pushes a talk to the LD label, the green answer-back LED on the lighting
director’s beltpack will begin to flash. To answer back, the LD can either push the
center button on the face of the beltpack, or can scroll back to page 1 and push
the talk on the rotary encoder above the DIR label.
The other application of the answer-back function is for a called beltpack to be
able to answer a call from another beltpack when the caller is not assigned to
their beltpack. This allows the possibility for a supervisor to directly contact
other staff on a one-to-one basis as needed, without giving them an accessible
link back to the supervisor. Those “one-way” routes would need to be
pre-assigned to the supervisor’s beltpack via the base-station programming.
In this manner, a stage manager labeled STMGR could contact a particular other
beltpack such as PROP3 by having that label assigned to a key on the STMGR
beltpack. By pushing the talk associated with that key, the stage manager could
initiate the answer-back function on PROP3’s beltpack and have a private
conversation. However, the props person could not initiate a direct conversation
back to the stage manager.
REGISTERING BELTPACKS WITH THE BASE STATION
The PC to Beltpack serial cable is used to register beltpacks with the basestation.
It can also be used to upgrade the firmware of the beltpacks. A PC software
utility program called CellCom 10 Toolkit is used in conjunction with this cable
to register the beltpacks.
For instructions on registering beltpacks with the basestation, and for upgrading
the firmware, see the CellCom 10 Toolkit User Guide.
The cable consists of a female 9-pin D type connector (PC connection) and a 3.5
mm (1.8-inch) stereo jack plug (beltpack connection). Care must be taken to
select a jack plug that fits completely through the plastic surround of the
connector at the bottom of the beltpack.
The data connections between the D connector and the stereo jack plug are as
follows: pin 2 to tip, pin 3 to ring, and pin 5 to sleeve. Pins 1,4,6 and 8 on the
PC connector are shorted together, as with the PC to CEL-BASE cable.

REMOVING REGISTERED BELTPACKS FROM THE BASE STATION
Beltpacks can be removed from the base station and new ones substituted by
using the CellCom 10 Toolkit program. The base station must be “told” that the
particular beltpack is no longer registered to it by entering “0000” as the beltpack
serial number. New beltpacks, either additional ones or replacements, will be
added as above in “Registering the Beltpacks.”
BELTPACK MENU OPTIONS
The CellCom 10 beltpack presents the user with a number of adjustable
parameters. The main categories of the adjustments are: Alarm Options, Audio
Options, View Status, and Adjust Contrast. An icon of a upward pointing arrow
designates EXIT or BACK, and is available on each menu page. Selecting this
icon and pressing the center ENTER button takes the user to the previous
screen, and exits to the main beltpack operating screen from the main menu.
ALARM OPTIONS
Low Battery Alarm
The low-battery alarm has two settings: On and Off. Using the scroll keys, select
the desired setting and then press the center ENTER key. When activated and
when the battery level is sufficiently low (approximately 20 minutes of remaining
battery life) the headset user will hear a beep at intervals to indicate that the
batteries must be replaced or recharged soon.
Low Signal Alarm
The low-signal alarm has two settings: On and Off. Using the scroll keys, select
the desired setting and then press the center ENTER key. When activated, a
beeping will be heard in the user headset when the user is almost out of the range
of the transceiver/antenna, and will soon lose connection with the system.
Two quick beeps are heard at approximately one-second intervals when the
display signal level icon is at the second-lowest increment. They are also heard
when the user goes completely out of range and connection is lost with the
transceiver/antenna (and the base). These beeps continue until the user moves
into an area where the signal is stronger.
This setting may be especially useful when a user is learning to establish the
coverage area for a particular location. Because the signal level when the alarm is
first activated is still strong enough for conversations to happen (though possibly
with occasional audio dropouts), it may not be desirable to keep this alarm on
during normal operation of the system. This low signal alarm is also useful for
checking out the coverage in a location when first setting up
transceiver/antennas, for either a temporary or permanent installation.

AUDIO OPTIONS
Headphone Off Level
This control allows the user to choose the signal threshold when the headphone
audio “turns off.” Level settings are - 6, -12, -18, and – 70 dB. The typical setting
is –70 dB, which functions as “always on.”
Page Lock
The Page Lock option puts the beltpack into a mode in which the page change
keys must be held down for two seconds to remove the page lock.
Headphone Limiter
This control introduces a limiter into to headphone audio circuitry, to control
excessive levels and resulting stress on the ear of the user. Level settings are – 6, 0,
+6, +12, and +16 dBu. The typical setting is –6 dBu.
Microphone Type
This control allows the user to select the proper setting for the headset
microphone being connected to the beltpack. The settings are Dynamic
(Balanced) Mic and Dynamic (Unbalanced) Mic. For most Clear-Com and other
headsets, the Dynamic (Unbal) Mic setting is proper.
Microphone Level
This control allows the user to set the level of the beltpack’s headset mic,
increasing or decreasing its gain going into the system. The gain settings are 40,
50, and 60 dB. The typical setting is 50 dB.
Headset Options
Three headset options are offered: Master Level, Sidetone Level, and Configure
PTT Switch. The Master Level control accesses a slide bar going from “-“to “+”,
and controls the overall maximum level that can be heard through the
headphones. This gain control permits adjustment among headsets with different
sensitivities, and for different use conditions (quiet studio versus loud live
performance environment). Typical setting is 2/3 to 3/4 of the way toward “+”.
Sidetone Level controls the amount of the user’s own voice (local sidetone) that is
injected into the headphone from the headset mic. It is activated when the user
pushes a “talk” or an Answer Back, letting the user know that the microphone is
on. It is not heard when no talk is pushed, or when the user goes outside of the
coverage area of a transceiver/antenna and is no longer connected with the
system.
3-10
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
The Configure PTT Switch has two settings which are global to all the talks in
the beltpack. The typical setting is PTT Switch Disabled.
VIEW STATUS
Role Information
Role Information gives the label (user name) that has been assigned to the
particular beltpack, and also gives a numerical Role Number which the system
uses – typically starting with 700 for the first beltpack and going up from there.
Beltpack Version
Beltpack Version gives the current software version on the beltpack, and a CRC
number. Use these numbers to determine whether the beltpacks contain the
latest software version, and to confirm the success of a software upgrade.
Beltpack ID
Beltpack ID, also known as IPEI, gives the unique identification number for the
transceiver in the CellCom 10 beltpack.
RF Carrier Mask
The RF carrier mask tells the base station and beltpacks which of the standard
DECT carrier frequencies to use. In Europe, for example, the standard carriers 0
to 9 (1880 to 1900 MHz) are designated as “0x03FF000000.” Other parts of the
world, such as South America, use Extended Carriers, such as 18 to 27 (1910 to
1930 MHz), designated as “0x0000007FE0.” The DECT stacks in both the
CEL-TA transceiver/antenna and the CEL-BP beltpack must be told which
group of 10 carrier frequencies to use via the “mask”, when they are first
initialized.
Connection Info
Connection Information defines all of the various DECT information for the
beltpack transmission and link to the transceiver/antenna. It also gives the
Carrier Number and Slot that the beltpack is currently using (this can
dynamically change as needed during use). In addition, the Received Signal
Strength Indication (RSSI) is numerically indicated, with 55 being the highest
value; also, the error percentage is shown.
ADJUST CONTRAST
Adjust Contrast provides a slide bar going from “-“to “+”, allowing the user to
adjust the contrast on the display. Typical range is between 1/2 and 3/4 toward
“+”.

THE CELLCOM 10
TRANSCEIVER/ANTENNAS
TRANSCEIVER/ANTENNAS (CEL-TA)
The CellCom 10 transceiver/antennas (CEL-TA) form the transmission link
between the CellCom 10 beltpacks and the CellCom 10 base. Multiple units are
used to support the beltpacks and to create larger, customized coverage areas.
Each CEL-TA is connected to the CellCom 10 base, either directly or via a
CEL-SP splitter. The unit has two flanges on the rear side that permit the unit to
be screwed or otherwise attached to surfaces.

A pair of omnidirectional antennas are provided with the transceiver/antenna.
They are screwed into a standard, gold-plated SMA connector.
Antennas with different coverage patterns (directional units) that are appropriate
for the 1.9 GHz range may be substituted for the provided antennas, if variations
in coverage pattern are required.

connections at both ends, as well as the powering.
3 Matrix Connector
This RJ-45 connector is used to connect the bi-directional signal from the
CellCom 10 base, directly or via the splitter. Up to 1,000 meters of 4-pair CAT-5
cable can be used for this connection between base and transceiver/antenna.
4 Power LED
This green LED indicates that the CEL-TA is receiving power, either from its
local power supply or from the connected CAT-5 cable (distances up to 300
meters, or 925 feet, from the base or the splitter) being powered via the CellCom
10 base.
5 DC In Power Connector
This connector is used to locally power the transceiver/antenna with the supplied
universal power supply. Use of local power is required when the CEL-TA is
located more than 300 meters (925 feet) from the CellCom 10 base or the
splitter, and is recommended even when the unit is closer whenever it is available
and convenient.
4-2
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
CABLING THE CEL-TA TRANSCEIVER/ANTENNAS
Each CEL-TA transceiver/antenna receives its necessary data and digital
communications audio via a direct connection with the CEL-BASE base station
transceiver ports. Between these two ports, up to 10 transceiver/antennas can be
supported. A CEL-TA may either be directly connected to a base station port
using 4-pair CAT-5 data cable with RJ-45 connectors on each end, or it may be
connected to the base through a CEL-SP antenna splitter.
BELTPACK SUPPORT CAPACITIES FOR TRANSCEIVER/ANTENNAS
Each CEL-TA transceiver/antenna can support up to five CEL-TA beltpacks
within one coverage zone. With the supplied omnidirectional antennas, the
coverage pattern is circular or donut-shaped, with a maximum range of up to 250
meters (800 feet), but with typical range between 50 meters and 150 meters –
depending on the use environment.
When designing the system, determine how many beltpack users will be in or
passing through a given coverage zone. If it will be 5 or fewer users, then place
one CEL-TA transceiver/antenna in the center of that area. If it is between 6 and
10 users, place two CEL-TA’s next to each other, both with a direct connection to
the CellCom 10 base or splitter. In larger systems – approaching 20 beltpacks – it
is wiser to allow one CEL-TA for every 3 to 4 users to ensure smooth handoffs
between transceiver/antennas.
If a sixth beltpack user goes into a coverage zone with only one CEL-TA
transceiver/antenna, and that user is out of range from another CEL-TA in the
overall system to which that beltpack is currently connected, it will lose
connection with the system. This is because the CEL-TA has a maximum
capacity of 5 beltpacks at a time. If one of the existing users in that coverage area
turns off a beltpack or leaves the area, then the sixth beltpack will find an open
slot and will be reconnected with the system.
The proprietary technology within CellCom 10 permits the beltpack user to go
between coverage zones created by different CEL-TA transceiver/antennas
connected to the CellCom 10 base, and for the system to hand over the
communication between beltpack and base from one CEL-TA to the next one.
Thus, a larger, customizable communications area may be designed.
COVERAGE AREAS UNDER VARIOUS CONDITIONS
Just as with any other product communicating via radio waves, the effective
distance between the beltpack and the transceiver/antenna (the range) will differ
depending on the particular environment in which it is being used. Radio waves
can be attenuated by walls, floors, ceilings, trees and shrubbery in an outdoor
setting, the human body (such as an audience), and numerous other objects.
They can be reflected and or stopped by metallic objects such as structural
beams, safety doors, lighting equipment and truss, bodies of water, and so on.
Under ideal conditions, the maximum range between a CellCom 10 beltpack
and a transceiver/antenna is 250 meters (about 800 feet). Typical distances are
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
4-3
between approximately 50 meters (about 160 feet) and 150 meters (about 485
feet), depending on the particular environment.
As the CEL-TA transceiver/antenna requirements for a particular installation are
being determined, keep in mind both the number of beltpack users who will be
working in a particular area (based on the 5-beltpack capacity of each CEL-TA),
and the layout and potential RF attenuating and reflecting items in the location.
Be conservative in your distance estimates to make sure that you include enough
transceiver/antennas to provide the necessary coverage for the installation. Also
note that additional CEL-TA’s may be added to a base, up to a maximum of 10.
TRANSCEIVER/ANTENNA SETUP RULES AND TIPS
Keep the following general rules and tips in mind:
• Keep antennas high (typically, though lower placements away from interfering
objects can at times be beneficial) and line-of-sight.
• Keep them away from larger metallic objects and surfaces, and from lighting
truss.
• With the CEL-TA with the provided omnidirectional antennas, the coverage is
circular so put the transceiver/antennas in the center of the area in which you
want coverage.
• In outdoor settings with line-of-sight, the absence of beneficial reflections of
the radio waves may lead to shorter than expected range; directional antennas
may be of benefit here.
• When overlapping the coverage zones of transceiver/antennas to create larger
continuous coverage areas, test the in-between areas with a beltpack for
potential areas of low RF signal; adjust the positioning of the CEL-TA’s as
needed.
• Because of potential body shielding as the user moves, it will be useful to place
two transceiver/antennas in different locations within larger working areas to
minimize low-level signals and potential signal dropouts.
• Going between a larger area and a corridor via a door, especially a heavy or
shielded one, or where the walls are thick, place a second antenna in the
corridor near the doorway to assure continual coverage.
TRANSCEIVER/ANTENNA SPLITTER (CEL-SP)
The CEL-SP splitter is the device that connects multiple CEL-TA
transceiver/antennas to the CellCom 10 base station. It has an RJ-45 connector
that carries the data between a base transceiver port and the splitter, and five
RJ-45 connectors to feed that information to and from up to five CEL-TA’s. The
splitter is always locally powered via the supplied external in-line universal power
supply.

CONNECTING THE CEL-SP TO CELLCOM 10 BASE AND CEL-TA TRANSCEIVER/ANTENNAS
After the connections have been made between the splitter and the
transceiver/antennas, make sure that the data LED’s are lit at the individual ports
on the CEL-SP splitter. Also make sure that the both the green Power LED and
the yellow Data LED is lit on each CEL-TA transceiver/antenna. If all are
properly lit, then the connection has been successfully made and the coverage
zones will be active and will support beltpacks. If the transceiver antennas are not
lit, check the connections.

INSTALLATION
INITIAL SYSTEM SETUP
A CellCom 10 system can work out of the box, as long as the beltpacks are
registered to the base, using the generic user labels for the beltpacks and the
rear-panel connections. The first stage in setup is placing the base station in a
convenient location, knowing that it is the central routing unit of the CellCom
10 system. It is also the means of programming the system, creating and
changing user labels, and creating and modifying the groups and
communications paths within the overall system. You will want to make it
accessible.
At this stage, if they are unregistered, you may want to register the beltpacks, or
at least one or two for system setup and testing, with the base station. Follow the
instructions in the section titled Registering Beltpacks with the Base Station in
the CEL-BP beltpack section of the manual.
The next step is to determine where the CEL-TA transceiver/antennas will be
located to provide the necessary coverage areas for all of the beltpacks [See section
below on System Installation and Defining Coverage Areas]. What areas will
have more than 5 active beltpack users in them at any time? Co-locate a second
CEL-TA there.
Is there a central place to locate a transceiver/antenna so that it will provide
omnidirectional (all directions / circular) coverage? Are there balcony areas,
corridors, or other rooms or areas that will require coverage with
transceiver/antennas? Then figure out where the CEL-SP splitter(s) that feed
these transceiver/antennas will be safely located. [For systems with only one or
two CEL-TA transceiver/antennas, the cable runs will go directly from the two
transceiver ports on the base station.]
Run 4-pair CAT-5 cable from the CellCom 10 base to the splitter, and determine
that the splitter is showing both power (green LED lit) and signal (yellow LED lit
when the base station is on). Run 4-pair CAT-5 cable from the splitter to each of
the CEL-TA transceiver/antennas. Make sure that the local power supplies are
plugged into the CEL-TA’s, unless they are close enough to the base station to
draw power from the attached CAT-5 cable.
You will know that the CEL-TA has sufficient power from the cable if the green
power LED and the yellow data LED light up. If you have several longer runs
and are attempting to power the transceiver/antennas from the base / splitter
connection, check each one again when the are all connected. The local powering
for the CEL-TA is recommended in most cases to provide the most reliable
long-term CellCom 10 installation.
Note that 4-pair CAT-5 cable with RJ-45 connectors on each end is specified for
connection between the CEL-BASE base station and the CEL-TA
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
5-1
transceiver/antennas. Use of other cable can result in markedly shorter distances
of cable runs and other possibly other performance problems.
During the initial system setup, before walking through the system with a
beltpack to check for gaps in coverage, it is wise to avoid “permanently” installing
the CEL-TA transceiver/antennas. Hold them in place in some temporary way
until their optimal position is determined.
Once the base, splitter(s), and transceiver/antennas have been placed and wired,
turn on a CEL-BP beltpack (assuming that it has been registered with the base
station) and walk the coverage area – ideally speaking with someone else via the
on-base headset or a party-line or matrix connection with the base. Alternately,
use the “site survey” mode on the beltpack (see the System Installation and
Defining Coverage Areas section below). It is often best to begin with one
transceiver/antenna in place, and then place additional units to enhance
coverage.
Walk through all of the areas where beltpack users will typically be moving, and
note any areas of weak signal, dropout, or disconnection from the system. Pay
special attention to the overlap areas between CEL-TA coverage zones, making
sure sufficient signal strength is there from each of the transceiver/antennas to
make a clean handoff between them for the beltpack.
Finally, when the CEL-TA coverage zones have been properly and effectively set
up, it is time to program the system. Programming involves creating the desired
user labels for each beltpack and rear-panel connection, putting these individual
items into groups as needed, and then assigning individual and group labels to
each of the beltpacks to establish the desired communication routes. See the
Initial System Programming section below for more details.
INITIAL SYSTEM PROGRAMMING
Programming of a CellCom 10 system has three basic stages. The first is creating
individual labels for the beltpack users and the rear-panel wired connections.
Labels are alphanumeric and can be up to 5 characters long. These could be
actual user names such as “John” or “Susan”, designations of roles such as “DIR”
or “AUDIO”, or connections such as “PL_A” or “MTX_3”. Creating labels is
done in the BELTPACKS menu subsection and the PORTS menu subsection,
under the LABEL heading.
The second stage is creating communications groups from the individual
beltpacks and rear-panel wired connections. Groups may also be labeled with a
unique five-character alphanumeric designation. Up to ten groups can be
created, with as many members as desired, and stored within the CellCom 10
base station. Creating and labeling groups is done in the GROUPS menu
subsection, under the EDIT and LABEL headings.
The third stage is to assign the desired group labels or individual labels to each
beltpack. Up to 6 group and/or individual labels may be assigned to each
beltpack on one of three beltpack “pages”, each of which has places for two labels
corresponding with the two rotary encoder push-to-talk level controls. Assigning
communications routes to beltpacks is done in the BELTPACKS menu
subsection, under the KEYS heading.

CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
SAVING PROGRAMMING CHANGES
Changes made on the CellCom 10 base station are not programmed into the
system memory until the save procedure is done. Going through this procedure
writes those changes into the flash ROM of the system and they remain that way
until further changes are made.
The save procedure may be initiated in two ways. The simplest method is to
press and hold the rotary encoder for about 3 seconds. This can be done
anywhere in the menu structure. The display screen will then show a “saving
changes” message for a few seconds, after which they are in effect. Exit the menu
where the change has been made.
Alternatively, go to the SYSTEM menu on the main screen, as shown in Figure 1,
and select it. Then scroll to the SAVE item, highlight it, and press the rotary
encoder. The same save procedure as above is initiated.

Figure 5: When “Label” is highlighted, press the rotary encoder to select
The current five-character designation will appear, as shown in Figure 6, with the
highlight on the first character. Pressing the rotary encoder will select that
character, and then turning the encoder clockwise or counterclockwise will
change the character, going through the entire sequence of possible characters at
one character per “click.” Once the desired character is reached, press the rotary
encoder to select it, and scroll to the next character to edit.
Figure 6: The current five-character designation will appear
After editing each in turn, click on the last (fifth) character to return to the
previous level of the menu.
Note: If you are creating a label that is shorter than five characters, you will still need
to go to the fifth character location and press the rotary encoder twice in order to exit
the label-selection menu – even if it is blank.
The character set goes from capital letters to lower-case letters, then to two sets of
specialized alphabetical characters, to symbols, and then to numerals.
To go back to the menu level above to select another beltpack to edit, scroll
clockwise to the BACK command to go up one level. Note that BACK can only
be reached by scrolling clockwise.

Use the rotary encoder to scroll to the desired port label (note the moving
“highlight”), and then push the rotary encoder to select. A menu to edit that port
will appear that will say “Selected XXXX – label”, with the first item being
LABEL, as shown in Figure 9. Since it is the first item in the list, it will be
highlighted. Press the rotary encoder to select.

CREATING AND EDITING GROUPS
Once a group has been given a unique label, if desired, the user may “populate”
that group by assigning beltpacks and rear-panel wired connections to it. Use the
following procedure for creating and/or editing groups.
From the main CellCom 10 menu screen, first scroll to the GROUPS menu item
and press the rotary encoder. The resulting page shows the first five of the
possible ten groups available within FreeSpeak Lite. Scroll through the groups
until the desired group label is highlighted, and then press the rotary encoder to
select. On the resulting menu page, scroll to MEMBERS and select. The message
on the top of the screen will say “Editing Members of GP#xx – label”. (See Figure
16.)
Figure 16: First five of the possible ten groups
Figure 17: Second five of possible ten groups
On that set of pages will be all of the base-station connectors, from HDSTA
(headset A) through STGAN (stage announce), followed by the labels for all ten
CellCom 10 beltpacks. Scroll through this list to find the desired members for
the group being created. Pressing the rotary encoder when a particular item is
highlighted will select that label as a member of the group, and a box will be put
around it.
Any labels which have already been selected as members of that particular group
will have a box around them. To de-select any labels that have already been
selected, highlight that label and press the rotary encoder. Pressing the rotary
encoder effectively works as a toggle switch, first selecting the item by putting a
box around it, and then de-selecting it and removing the box.
When all of the desired beltpack labels and base-station connection labels have
been selected and have boxes around them, scroll clockwise to BACK and press
the rotary encoder to exit the selection process. Then scroll to the BACK
command in the next menu and press the rotary encoder. The selected members
of that particular group may now be saved in the system memory.
To edit a group that already has members, go through the procedure above to
reach the member labels. Scroll through the list, using presses of the rotary
encoder to select new members and de-select members that are no longer desired
5-8
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
to be members of that particular group. Exit as above, and save the changes in the
system memory.
ASSIGNING LABELS TO BELTPACKS
Once all of the beltpacks and base-station connections have been labeled and
saved as desired, and groups have been labeled and assigned members, it is time
to assign these communication routes to the individual beltpacks. For this
explanation it is assumed that the beltpack assigned to position one – BPK01 – is
having its communications routes assigned. The procedure is identical for all
remaining beltpacks.
From the main base station menu, select BELTPACKS with the rotary encoder.
Then select the EDIT command, and the list of available beltpacks will appear.
Scroll to and select the desired beltpack, in this case BPK01. The display will say
“Selected BPK01-label.” On the editing menu that appears, highlight the KEYS
command, and press the rotary encoder.
Figure 18: Highlight the “Keys” Command
The message “Select T/L Key to be Edited” will appear at the top of the page,
and the numerals “1, 2, 3, 4, 5, 6” will be available with “1” being highlighted.
(See Figure 19.)
Figure 19: Select Push-to-Talk/Level Control Key to Edit
These numbers correspond to the combination of the level control/push-to-talk
rotary encoders on the CellCom 10 beltpack, with “1” being the left/”Talk A”
rotary encoder on beltpack “page 1,” and “2” being the right/”Talk B” rotary
encoder in beltpack “page 1.” The combinations “3, 4” are those same rotary
encoders on beltpack “page 2,” and “5, 6” are for beltpack “page 3.” Thus, the
three pairs of communications routes available for assignment on a CellCom 10
beltpack can be programmed via these numerals 1 through 6.
On the base station display, scroll to the desired key to assign on the beltpack
currently being programmed. For this example, say that it is key page 1 on the
beltpack, and left-hand rotary encoder. Press the rotary encoder to select. A list
will appear that starts with the base-stations connections (headset, party-line,
4-wire, etc.), followed by each of the ten individual beltpacks, and finally by the
ten available groups. Scroll through this list, either clockwise or counterclockwise
since they are in a continuous loop, until the desired label is highlighted.
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM

Figure 20: Select the label to assign to that beltpack key
Press the rotary encoder to select the label to assign to that beltpack key, and a
box will appear around it. After approximately 3 seconds, the display will
automatically return to the beltpack editing menu, and they communications
path to that particular beltpack and key “1” will have been assigned. To assign
the other keys in turn to that beltpack, scroll to the KEYS menu item, select it,
scroll to the next numeral – Pg. 1-2 through Pg. 3-2 – and use the same
procedure to choose a label to assign to it.
When the particular beltpack has had assignments made to all of its keys, select
BACK on the beltpack editing menu and return to the list of available beltpacks.
Highlight and select the next beltpack for key assignment, and repeat the above
procedures.
BASE STATION SYSTEM MENU
The base station SYSTEM menu offers several system-wide capabilities,
including overall system gain, an alternative means to save programming
changes, and the ability to lock the front-panel enable buttons.
By selecting GAIN, the overall system gain can be increased or decreased. The
levels are numerical, ranging from level 0 to 3 dB. After making a change, save it
to the base station memory using the save procedure.
Highlighting SAVE and pressing the rotary encoder initiates the save procedure
for any programming changes that have been made. Using this method has the
same effect and pressing and holding the rotary encoder for approximately three
seconds.
The LOCK menu allows the user to select whether to lock or unlock the
front-panel enable buttons for wired party-line connectors A and B, and the
wired program input. By selecting ON for the lock, the current state of those
enable buttons is maintained, and is retained even when the unit is turned off
and restarted. The buttons can be locked in either the enabled or the disabled
position, in any desired combination. Selecting OFF allows the buttons to be
toggled on and off with a single push.
The following feature is not in the SYSTEM menu, but is an overall system item.
To determine the version number of the base station firmware, press and hold all
three of the front-panel enable buttons simultaneously. The version number and
its date will appear on the display screen. The IP address and system
5-10

identification number are also given. To close this display and go back to the
main screen, push the rotary encoder.
Figure 21: Main Menu
SYSTEM INSTALLATION AND DEFINING COVERAGE
AREAS
The coverage area of any given CEL-TA transceiver/antenna depends on the
particular environment in which it is located – what RF absorptive or reflective
barriers and objects are between it and the beltpacks that it is to support. So as in
all cases of placing antennas for radio transmission, measurement and best
estimates are combined with some level of actual testing with the equipment in
the environment. Wireless intercoms are lower power devices, and do not
approach the range of simplex devices like walkie-talkies.
The maximum range between a CellCom 10 transceiver/antenna and a beltpack
is 250 meters (about 800 feet) under ideal circumstances. In normal practice,
expect between 50 meters and 150 meters, and plan accordingly. When trying to
provide coverage through thick walls and when plenty of metallic obstructions
are present, expect the range in that direction to be on the shorter side. Plan to
place a transceiver/antenna on the other side of the wall, or in the corridor. For
more open, line-of-sight places, you can expect that the range will be better in
that direction.
The CellCom 10 beltpack has a “site survey” mode that is invaluable when
setting up coverage areas. This mode is entered by holding down the left and
right scroll buttons on the front panel of the beltpack while at the same time
pressing the power switch on the rear panel to turn the unit on.
The screen that appears contains various connection information. For setting up
the system and coverage areas, the most important section is the RSSI (Received
Signal Strength Indication) designation in the lower left-hand corner of the
display. To the right of “RSSI:” will be a number, ranging from 55 at the highest
signal strength to 0 at the lowest.
This signal strength number will fluctuate as you move through the coverage
area, and may even fluctuate as you stand still. Best system performance will be
obtained if the signal strength remains at 30 or above – which is approximately
equivalent to the lowest two “squares” being shown in the signal-strength icon on
the main screen of the CellCom 10 beltpack during normal operation.
A similar process can be done with a beltpack that is in standard mode, and is
connected with a headset. Press one of the talks so that the headset’s mic is
activated. You will hear your own voice in the earpiece, unless the local sidetone
in the beltpack menu is completely turned down. Alternatively, you can inject a
CELLCOM 10 WIRELESS COMMUNICATION SYSTEM
5-11
program source into the PRGM connector or a 4-wire connector and assign it to
the beltpack.
Walk the area and talk, either to someone else connected to the system or
test-talking. Also watch the signal-strength icon on the display. Listen for audio
dropouts, and look for low signal indication. The beltpack will lose its
connection to the base and display “Searching for Network” when the range has
been completely exceeded.
Once the first CEL-TA transceiver/antenna has been placed and its limits have
been explored and noted, place other CEL-TA’s in locations where their coverage
will overlap with the weak-signal areas that were noted with the first
transceiver/antenna. Then walk between those coverage areas to determine that
the coverage is continuous and complete; if not, reposition the additional
antennas. Use this method to create the entire desired coverage area.
Now, co-locate other CEL-TA transceiver/antennas in any areas where more than
five beltpacks will be operating at any time. Run an additional CAT-5 cable from
the base / splitter, and attach the new transceiver/antenna adjacent to the existing
one.

GLOSSARY
Base Station All communications and data flow through the 1-RU CellCom
10 base station. The base station supports up to 10 wireless beltpacks. Because
each beltpack has its own timeslot, it can be individually addressed by the
base–allowingmultiple combinations of beltpack-to-beltpack and small-group
conversations to happen simultaneously.
Beltpack The unit from which you talk and listen. Up to six communication
routes can be assigned to a CellCom 10 beltpack.
DECT The Digital Enhanced Cordless Telecommunications Standard (DECT)
provides a general radio access technology for wireless telecommunications.
DECT is designed to provide access to any type of telecommunication network,
thus supporting numerous applications and services. Exclusive radio frequencies
protect DECT from interference from other radio systems. The DECT standard
is used in more than 110 countries worldwide, including the whole of Europe.
Transceiver/Antenna The communication between the CellCom 10
beltpacks and the base staton is done through the CEL-TA
Transceiver/Antennas. Unlike other wireless intercom systems, where the receive
and transmit functions are in the base, CellCom 10 places that function within
the transceiver/antennas.
