2. Link Wireless Telephone System Description
This section generally explains the installation and site requirements of the Link
WTS. The Link WTS is a wireless communication system that allows hand-held Link
Wireless Telephones to communicate using the existing telephone system.
The Link WTS’s advanced micro-cellular architecture utilizes Base Stations, or cells,
located throughout the facility to accommodate on-premise roaming. As a handset
user moves within the coverage area, the call is seamlessly passed between cells. The
Link 3000 MCU supports up to 3,200 users and millions of square feet of coverage,
resulting in a scalable enterprise-wide wireless voice solution.
For simplicity, this manual refers to the existing wired phone system,
whether an on-premises PBX or Telco-provided Centrex system, as the
“telephone system.”
The Link WTS uses a micro-cellular design consisting of three primary components:
the Master Control Unit (MCU), Base Stations, and Wireless Telephones (handsets).
The following diagram shows an overview of the system.
Link Wireless Telephone System

SpectraLink Corporation Installation
Link WTS – Link 3000 MCU
Part Number: 72-0059-01-J.doc Page 10
3. Link Wireless Telephone System Components
3.1 The Master Control Unit
The Master Control Unit is the processing center for calls to and from the Link
Wireless Telephone System. It consists of at least one primary shelf (MCS300) and
may have up to 19 expansion shelves. Residing adjacent to the telephone switching
equipment, the MCU operates as a standalone, external system while maintaining full
PBX functionality for handset users.
The MCU connects to the telephone system in two ways. The MCU can either
interface with analog ports of the host telephone system or, in many cases, connect
directly to the telephone system (PBX or key/hybrid system) via a digital interface. A
digital interface provides the advantage that all switch features, such as call party
name display and multiple line appearances, are preserved for the end user.
The MCU provides connectivity from the telephone switch to the wireless system
components. Telephony ports for each handset are commissioned from the
telephone switch. Base Stations, which provide the wireless link to the handsets, are
wired directly to the MCU.
The Link WTS Topology
Components in the Link WTS are designed in a star topology. At the center is the
Link 3000 MCU. The primary shelf contains the system controller, which manages
the call processing for the wireless network. Additional expansion shelf controllers
manage intra-shelf calling and work with the system controller to pass calls within
the wireless network and to the telephony switch. All shelves provide universal slots
for up to ten Interface Modules. Interface Modules connect Base Stations and
handsets to the system. Up to 20 shelves can be connected together to maximize the
system capacity.
The following diagram illustrates a sample star topology for the Link WTS.

Shelf
Shelves are designed for 19” rack or wall mounting. Each shelf has 12 universal card
slots. The first two slots are reserved for controller cards, the remaining ten slots are
for Interface Modules. Wiring to each card is on the front panel. Power is -48V DC
through the back or side panel.
System Controller (CSC or CSO301, 306, and 320)
Each system requires one system controller card, which occupies two slots (slots 1
and 2) in the main shelf. The system controller supports call routing within the entire
system and to external ports. Each model number of System Controller (301, 306,
and 320) supports a different number of expansion shelves. The CSO model System
Controller supports Open Application Interface (OAI) enabled expansion shelves.
Two RS-232 serial ports are provided on the system controller. Serial ports can be
used for multiple purposes, including local administration, remote administration and
diagnostics (via modem), OAI applications and call detail recording. One standard
10-base T Ethernet port is also provided (for future use).
Expansion Shelf (CSC300, CSO300)
An Expansion Shelf Controller (CSC300) resides in slot 2 of each expansion shelf.
The Expansion Shelf Controller manages intra-shelf traffic and communicates with
the system controller. The CSO300 Expansion Shelf Controller supports an OAI
enabled expansion shelf.
Part Numbers with a CSO prefix have the same functionality and
capacity as the corresponding CSC Part Numbers and also support the
Open Application Interface(OAI)
Interface Modules (CPA, CPU, CPM, CPP, CPF316)
Telephone line and Base Station connections are made to the Interface Module.
Each card provides 16 line (handset) interfaces and 6 Base Station interfaces.
Interface Modules are installed in slots 3 through 12 on a shelf. Interface Modules
include: Analog (CPA316), Universal (CPU316), Mitel interface (CPM316), four-wire
digital (CPF316), and Panasonic (CPP316). The Interface Module type is defined via
the Operator’s Console and software when the card is installed. Interface Modules of
different interface types can be mixed within a shelf.
Interface Modules are “hot swappable”; they can be removed and replaced without
affecting service on the rest of the system.
Intershelf Junction Panel (JPI300)
The Intershelf Junction Panel (JPI300) connects Expansion Shelf Controllers on
expansion shelves to the system controller, creating a completed communication
channel between network elements. The Intershelf Junction Panel physically
connects the network, converting RJ-21 connections from the System Controller to
the RJ-45 connection on the Shelf Controller.

Part Number: 72-0059-01-J.doc Page 13
3.2 Base Stations
Radio Base Stations,or cells, provide the communication channel between the MCU
and the handsets. The Base Station and handset use digital spread spectrum radio
transmission in the 902-928 MHz frequency band.
Each Base Station supports multiple users and covers a transmission area in excess
of 50,000 square feet. The signal propagation is dependent on transmission
obstructions within the building. A call is passed from one Base Station to another as
the user walks throughout the coverage area. The Link WTS is designed to provide
seamless coverage, enabling real-time hand-off of active calls.
SpectraLink
Base Station
ccLink Wireless Telephone System
The ccLink Wireless Telephone System (WTS) is designed to meet the high
simultaneous call capacity and advanced level of telephone feature integration of the
call center environment. The ccLink WTS uses a special High Density Base Station
which can be installed with minimal spacing (as little as 20 feet between Base
Stations.)

SpectraLink Corporation Installation
Link WTS – Link 3000 MCU
Part Number: 72-0059-01-J.doc Page 14
3.3 Link Wireless Telephones
The Link Wireless Telephone is a durable wireless telephone that operates with all
the functionality of a wired desk phone. Weighing only six ounces and ergonomically
designed, the handset is comfortable and easy to use. The monolithic design of the
handset, with no moving parts, will withstand a physically demanding work
environment. The handset’s alphanumeric display supports messaging from either
the telephone switching equipment or an external data application. The handset
provides up to four hours of talk time and 80 hours of standby between battery
recharges.
When the Link WTS is connected to the telephone system using analog ports, the
handset will provide many of the calling features of a desk phone, including transfer,
conference calling, and hold. When the system is digitally interfaced to the phone
system, the handset will also support the advanced features of the host telephone
system such as calling party name display and multiple line appearances.
The Link PTB 4xx Wireless Telephone
Each handset requires a line appearance (port) from the telephone system. Typically
the handset extension number corresponds with the user’s internal telephone
extension number. On most switching systems the user’s desk phone and the
handset port can be bridged so that incoming calls ring both phones simultaneously.
3.4 Operator’s Console
The system uses a proprietary software program for administration and maintenance.
The software is loaded to the Operator’s Console, an IBM-compatible personal
computer, located close to the Link 3000 MCU. The PC is used to register each
handset and Base Station, enter user information, monitor system operations, and
initiate remote diagnostics.

4.3 Prepare Power for Shelves
The Link 3000 MCU requires a -48V DC power source. The -48V connection is
comprised of three wires: -48, +48 (neutral), and ground.
SpectraLink recommends that a licensed electrician install the -48V power source. It
must be installed according to current National Electrical Code (NEC) or National
Fire Protection Code standards, in accordance with all local and municipal electrical
code recommendations.
Use of 14 AWG wire is recommended.
See section 5.5 Connect Power to Shelves for more information on power connections.
When connecting the -48 V DC system to power, note the
following precautions:
A 30 amp circuit breaker must be present on the non-grounded DC
circuit conductor, and the installer must ensure that means are provided
for connection of the equipment to the DC source by permanent wiring
methods, and no disconnecting device is located in the grounded DC
circuit conductor between the point of connection to the supply and the
point of connection to the grounding electrode and equipment
grounding conductors.
4.4 Run Cables to Base Station Locations
The Base Station locations should be designated on the building floor plans provided
to the field service engineer. Base Stations can be mounted easily on raised or

acoustical ceiling tiles, or on the wall. Avoid locating Base Stations in high or hard-
to-reach places, as this will hinder maintenance, testing, or repositioning.
Wire Specifications
The customer’s wire contractor is responsible for adhering to all local
codes for wiring.
SpectraLink recommends UL-listed wire that conforms to the following
specifications for AWG, distance, and number of power pairs required for this
installation.

One additional pair is also required for Data.
For wire runs of less than 3,500 feet, attenuation must not exceed 6.8
dB/1,000 feet at 772KHz.
For wire runs between 3,500 and 6,000 feet, attenuation must not exceed
4.5 dB/1,000 feet at 772KHz.
Wire that is already installed (spare house cable) can be used when it is available.
House cable will usually run from the MDF in the telephone equipment room to
intermediate distribution frames (IDFs) spread throughout the facility. Install new
wire from the closest IDF to the Base Station. Be sure no bridge taps, multiples, or
“Y” connections are created or present.
Determine the amount of wire needed to connect the Base Station to the MCU by
scaling from a floor plan or a sketch, pacing, measuring, or estimating. Remember to
include enough wire to reach the ceiling.
The wire length between the MCU and each Base Station may not exceed
6,000 cable feet.
Install an extra 25 feet of wire at the Base Station to allow for possible
relocation.
Pull Cable
Pull the cable from the MCU location (usually in the telephone equipment room) to
the Base Station locations designated on the floor plans.
If the cabling exits the building, refer to section 6.3
Install Outdoor Base
Stations .
Run all cable before attaching the RJ-45 connectors to the Base Stations. Label both
the demarcation block end and the Base Station end of each wire with the Base
Station number using a wire tie marker or other form of marker.
