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 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 Wireless
Phone 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. The following
diagram shows an overview of the system.
Link Wireless Telephone System
Part Number: 72-0059-01-Ha.doc Page 11

SpectraLink Corporation Installation
Link WTS – Link 3000 MCU
2.1. The Master Control Unit
The Master Control Unit (MCU) is the processing center for calls to and from the
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 Wireless Telephone 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 Wireless Telephone are commissioned from the
telephone switch. Base Stations, which provide the wireless link to the Wireless
Telephones, 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 Wireless Telephones 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 inch 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 (slot 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 (CSC-300) 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 (Wireless Telephone) 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
Part Number: 72-0059-01-Ha.doc Page 14

SpectraLink Corporation Installation
Link WTS – Link 3000 MCU
connects the network, converting RJ-21 connections from the System Controller
to the RJ-45 connection on the Shelf Controller.
SpectraLink
2.2. Base Stations
Radio Base Stations,or cells, provide the communication channel between the MCU and
the Wireless Telephone. The Base Station and Wireless Telephone 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.
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.)
Part Number: 72-0059-01-Ha.doc Page 15

SpectraLink Corporation Installation
Link WTS – Link 3000 MCU
2.3. 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 Wireless Telephone is comfortable and easy to use. The monolithic design
of the Wireless Telephone, with no moving parts, will withstand a physically demanding
work environment. The Wireless Telephone’s alphanumeric display supports messaging
from either the telephone switching equipment or an external data application. The
Wireless Telephone 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
Wireless Telephone 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 Wireless Telephone will also support the advanced features of the host
telephone system such as calling party name display and multiple line appearances.

The Link Wireless Telephone
Each Wireless Telephone requires a line appearance (port) from the telephone system.
Typically the Wireless Telephone extension number corresponds with the user’s internal
telephone extension number. On most switching systems the user’s desk phone and the
Wireless Telephone port can be bridged so that incoming calls ring both phones
simultaneously.
2.4. 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 Wireless Telephone
and Base Station, enter user information, monitor system operations, and initiate remote
diagnostics.

Prepare Rack or Wall
The Link 3000 MCU can be mounted in a rack or on the wall. Rack or wall support must
be adequate to support the number of shelves to be installed. Each fully loaded Link 3000
MCU shelf weighs approximately 35 pounds.
Rack Mounting
Before installing shelves in a rack, be sure the rack is mechanically fastened to the
floor or wall such that it properly supports the number of shelves to be mounted.
Follow the manufacturer’s instructions to prepare the rack.
Be sure to leave 1.5” clearance at the rear of the racks for power conduit.
Wall Mounting
Before wall mounting, cover the wall with ¾” plywood. Secure the plywood to
the wall studs every 16 inches with an adequate number of screws to support the
number of shelves to be mounted. Each fully loaded shelf weighs approximately
35 pounds. Be sure to leave 1.5” clearance on the left side for power conduit.
