2. Installation Overview
Installation has several phases. In some cases, a separate person is responsible for each
phase. It is important to coordinate the activities among the persons involved.
The customer or vendor installs the access points per the Configuration Note for the
access point being used. This is normally done before the NetLink Telephony Gateway
installation, but should be done before step 3 below.
This document covers the first two steps that are usually done by the customer up to the
point of installing and connecting the NetLink Telephony Gateway(s) to the telephone
demarc blocks and LAN access device. At that point, a qualified SpectraLink installer
assists the customer in completing the remaining steps.
1. Site Preparation – done by the customer or a wire technician/contractor.
2. NetLink Telephony Gateway Installation – done by the customer or
SpectraLink.
If five or more NetLink Telephony Gateways are to be installed, a NetLink SVP
Server is required and would also be installed in this step.
3. NetLink Telephony Gateway Configuration – done by the customer or
SpectraLink per NetLink Telephony Gateway: Setup and Maintenance.
If a NetLink SVP Server has been installed, its configuration would also be done
in this step.
4. NetLink Wireless Telephone Configuration – done by the customer or
SpectraLink per NetLink Wireless Telephone: Setup and Administration.
5. System Certification – done after installation to confirm the system is working
properly per NetLink Wireless Telephone: Setup and Administration.
For more information about NetLink system architecture and components, please see
NetLink Telephony Gateway: Setup and Maintenance.

3. NetLink Overview
3.1 System Architecture
The NetLink Telephony Gateway and NetLink Wireless Telephone are SpectraLink's
wireless LAN-based telephony products. NetLink products operate in the 2.400-2.483
GHz unlicensed band, using either the frequency hopping (FH) or direct sequence (DS)
spread spectrum technology which is compatible with the IEEE 802.11 wireless LAN
standard. There are two models of the NetLink Telephony Gateway – an 8-line model
and a 16-line model.
NetLink Wireless Telephones operate as clients on the wireless LAN, alongside other
mobile 802.11 devices. Wireless LAN fixed radios, called access points (APs), receive
IP voice packets from Wireless Telephones and forward them to the NetLink Telephony
Gateway over the Ethernet LAN. The Telephony Gateway connects to the host telephone
switch using digital or analog line interfaces. Using SpectraLink’s exclusive LinkPlus
digital interface technology, Wireless Telephones are able to emulate proprietary digital
telephone sets, making advanced switch features such as multiple line appearances and
display features available to mobile users.
Up to forty NetLink Telephony Gateways may be connected to the LAN for a maximum
capacity of 640 NetLink Wireless Telephones. When more than four NetLink Telephony
Gateways are installed, the NetLink SVP Server must also be installed to manage the
increased load.

3.2 System Components
•
••
• NetLink Wireless Telephones – Employees can carry Wireless Telephones to make
and receive calls as they move throughout the building. The Wireless Telephones are
to be used on-premises; they are not cellular or satellite phones. They are connected
to the facility's existing telephone system and to the NetLink Telephony Gateway.
Just like wired telephones, they can receive calls directly, receive transferred calls,
transfer calls to other extensions, and make outside and long distance calls (subject to
the restrictions applied in your facility.)
Wireless Telephones use spread spectrum radio technology, which comes in two
variations, frequency hopping (FH) and direct sequence (DS). Although the outward
appearance and operation of the two Wireless Telephones is identical for both
varieties, some installations may find better radio performance with one or the other,
depending on local conditions affecting radio wave propagation or interference. The
spread spectrum technique used by the Wireless Telephones must match that used by
the access points. Discuss the choice of spread spectrum technology with your access
point provider. NetLink Wireless Telephones can operate at up to 11 Mb/s in a DSSS
(Direct Sequence Spread Spectrum) system.
•
••
• NetLink Telephony Gateway – serves as the connecting point, or gateway, between
the LAN and the existing telephone system. One or more NetLink Telephony
Gateways are typically installed in the telephone equipment room. Each NetLink
Telephony Gateway supports up to 16 telephone lines and Wireless Telephones. Up
to 40 NetLink Telephony Gateways can be connected to the LAN to support
additional telephone lines. If five or more NetLink Telephony Gateways are
connected to the LAN, a NetLink SVP Server must be installed to handle the
increased call volume.
SpectraLink offers digital NetLink Telephony Gateways that work with the digital
ports on most common brands of telephone systems (PBX or key systems). We also
offer an analog NetLink Telephony Gateway that works with telephone systems (CO,
PBX, or Key Systems) with analog (loop start) ports.
• Access Points – supplied by third party vendors, access points provide the
connection between the wired Ethernet LAN and the wireless (802.11) LAN. Access
points (AP) must be positioned in all areas where Wireless Telephones will be used.
The number and placement of access points will affect the coverage area and capacity
of the wireless system. Typically, the requirements for use of NetLink Wireless
Telephones are similar to that of wireless data devices. Contact SpectraLink, or a
certified SpectraLink distributor, for specific information about your facility’s needs.
The NetLink system must connect to access points that utilize SpectraLink Voice
Protocol (SVP). Contact SpectraLink, or a certified SpectraLink distributor, to verify
that your AP and its software version are supported.

Part Number: 72-0065-01-G.doc Page 13
• Ethernet Switch – a component in the wired Ethernet LAN infrastructure. Switches
interconnect multiple network devices, including access points and NetLink
Telephony Gateways. Ethernet switches are required to provide the higher
performance network connections needed to handle combined voice and data traffic.
• Router – an optional component in the wired Ethernet LAN infrastructure that
separates a wired LAN into segments so that network traffic is restricted to those
segments that are directly involved in the communication. Installation of a network
router is recommended in larger networks, where there may be significant network
traffic not related to the wireless LAN. A router will isolate the wireless LAN from
the associated wired LAN so that they are not impacted by each others’ traffic. The
NetLink Telephony Gateways, the APs, and their associated Ethernet switch must all
be on the same “side” of the router.
• NetLink SVP Server – the NetLink SVP Server manages call volume and speed. It is
a required component to utilize the 11Mb/s maximum transmission speed available in
the NetLink Wireless Telephone. It is required in any system when five or more
NetLink Telephony Gateways are connected to the LAN. With 40 NetLink Telephony
Gateway cabled together, the NetLink SVP Server supports a maximum of 640
telephone lines and 120 simultaneous Wireless Telephone calls.
SpectraLink Voice Priority (SVP) is the SpectraLink Quality of Service (QoS)
mechanism that is implemented in the Wireless Telephone and AP to enhance voice
quality over the wireless network. SVP gives preference to voice packets over data
packets on the wireless medium, increasing the probability that all voice packets are
transmitted efficiently and with minimum or no delay. SVP is fully compliant with
the IEEE 802.11 and 802.11b standards.
SVP is required for QoS because the current IEEE 802.11b wireless LAN standard
provides no mechanism for differentiating audio packets from data packets. This
standard is undergoing revision to version 802.11e to provide all the functionality of
SVP in an industry standard thus ensuring high-quality voice in a mixed client
environment. Once 802.11e is ratified, SpectraLink and its 802.11 technology
partners will adopt the new specification. When the 802.11e specification replaces
SVP, the Wireless Telephones can be upgraded and the NetLink SVP Server can be
removed from the system.
• Administrative computer – Required for setup and maintenance of the NetLink
Telephony Gateway and the NetLink SVP Server. This computer may be only
temporarily connected to the Ethernet switch; a dedicated computer is not required.
Some installations use a laptop to configure and maintain system components.

4.2 LAN Requirements
Network Infrastructure
The NetLink Telephony Gateway connects to your local area network (LAN). To
provide adequate bandwidth and limit collisions, an Ethernet switch is required. The
traffic between the NetLink Telephony Gateway and wireless LAN APs should be
isolated as much as possible to avoid additional latency. The NetLink Telephony
Gateway and APs must be on the same logical IP subnet. Inter-subnet roaming is not
permitted for wireless devices.
Each NetLink Telephony Gateway to be installed requires a 10 Mb/s switched Ethernet
connection.

SpectraLink Corporation Installation—NetLink Telephony Gateway
NetLink SVP Server
Part Number: 72-0065-01-G.doc Page 16
The NetLink Telephony Gateway and Wireless Telephones rely on wireless LAN APs to
transmit and receive packets from Wireless Telephone devices. The APs must be
compatible with the IEEE 802.11 standard for wireless LANs, either frequency hopping
or direct sequence spread spectrum radios. To configure a wireless LAN to support
NetLink Telephony Gateways and Wireless Telephones refer to SpectraLink’s WLAN
Application Notes for your LAN vendor.
IP Addressing
The NetLink Telephony Gateway, along with each of the wireless devices associated
with it, requires an IP address. The system administrator must determine what IP
addresses are to be used by the NetLink Telephony Gateway and APs. Wireless
Telephones can be configured to use DHCP or Static IP addressing. Record IP address
assignments on the Wireless Device Planning Worksheets—one for each NetLink
Telephony Gateway. The worksheets are started when the system is installed and the
information recorded on them is used in the setup and maintenance of the system.
NetLink Telephony Gateway: Setup and Maintenance covers assigning IP addresses to
the NetLink Telephony Gateway and Wireless Telephones. Consult the Configuration
Note for your specific AP for information about assigning IP addresses to APs.
4.3 Location of NetLink Telephony Gateway and
NetLink SVP Server
The specifications covered here allow for great flexibility in physical placement of the
components within stated guidelines.
Each NetLink Telephony Gateway and NetLink SVP Server measures approximately 4 x
12.5 x 7 inches, and weighs about five pounds. The units are designed to be wall
mounted, vertically or horizontally, over ¾” plywood.
Locate the NetLink Telephony Gateway and NetLink SVP Server in a space with:
• Sufficient backboard mounting space and proximity to the LAN access device
(switched Ethernet switch), telephone switch and power source.
• Easy access to the front panel, which is used for cabling.
• For the NetLink Telephony Gateway, a maximum distance of 250 feet from the host
telephone switch for a digital interface, and 325 feet (100 meters) from the Ethernet

5. Telephone Interface Configuration


The customer or the customer's wire contractor is responsible for adhering
to all local codes for wiring.
5.1 Prepare Demarc Blocks
The NetLink Telephony Gateway is connected to the existing telephone system using RJ-
21 connections. A NetLink Telephony Gateway is designed to operate with a specific
interface to the telephone system: two-wire digital, two-wire analog, or four-wire digital.
A four-wire system may require two demarc blocks.
Based on the number and type of interfaces in the system, determine the number of 25-
pair cables required to connect telephone line ports to the demarcation blocks.
If the wiring between the NetLink Telephony Gateway and the telephone
system leaves the building, consult your telephone system manual for
instructions on providing adequate lightning and other over-current
protection.
All NetLink Telephony Gateways (except the TGA116) are intended only
for connection to the isolated side of an on-premises PBX or key system.
The interfaces are intended to connect to digital PBX ports that provide
signals of 5Vp-p (max) AC components. Some PBXs provide a 48 V DC
offset.
Modem administration
The NetLink Telephony Gateway can also be accessed remotely using its internal modem
and a dedicated telephone line. If your site will use administration by modem, this
connection should be included in the wiring installation.
5.2 Install Telephone Demarc Blocks
The demarcation blocks used to connect the telephone system to the Telephony Gateway
should be installed on ¾ inch telephone facility backboard. Although this manual uses
66-blocks as examples, any standard cross-connect blocks are acceptable.
5.3 Assign and Program Telephone Ports
The wire contractor should inform the system administrator which telephone line
numbers have been designated for the wireless devices and the remote diagnostics
modem line.
The system administrator must assign extension numbers associated with the wireless
devices and plan the functions (trunk access, toll restrictions, system features, ringing

options, etc.) to be programmed. This programming will be done after the wireless
devices are assigned to the NetLink Telephony Gateway, but will be faster if planned in
advance by verifying the parameters and features on the current telephone system and
wired phones.
For more detail, consult the SpectraLink LinkPlus Digital Interface document for the type
of telephone system in use at your location.
5.4 Connect Telephone Lines to Demarc Blocks
Telephone cables are punched down onto the cross-connect blocks as shown in the
following demarc block diagrams.
Photocopy the Wireless Device Planning Worksheets as needed. Use the forms to track
the telephone line assignments connected to each NetLink Telephony Gateway. As the
installer punches down each telephone connection, record the information on the form to
identify the user and extension assigned. A copy of this form should be posted near the
cross-connect block.
