NetLink Telephony Gateway
2. NetLink Overview
The NetLink Telephony Gateway provides telephone functionality to NetLink
Wireless Telephones and NetLink Docking Stations over a wireless local area
network (LAN). The installation process connects the Gateway to an existing host
telephone system and LAN. The configuration process covers downloading current
software, setting network parameters, setting Gateway parameters, assigning wireless
telephones to the lines controlled by the Gateway, and establishing feature
programming. Maintenance covers adding and deleting handsets, upgrading software,
etc. The troubleshooting section provides directions for analyzing system
functioning via the System Status menu.
2.1 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.
Note that the 16-port Gateway and the 8-port Gateway are installed and configured
identically. Both support eight simultaneous calls. However, the 8-port Gateway will
be limited to eight line interfaces.
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 handsets 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, handsets 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 five or more
NetLink Telephony Gateways are installed, the NetLink SVP Server must also be
installed to manage the increased load.
2.2 SpectraLink Voice Priority (SVP) and Quality of Service
SVP is the SpectraLink quality of service (QoS) mechanism that is implemented in
the handset and an access point (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 compatible with the IEEE 802.11
standards.
The NetLink SVP Server is an Ethernet LAN device that works with the APs to
provide QoS on the wireless LAN. Voice packets to and from the handsets are
intercepted by the NetLink SVP Server and encapsulated for prioritization as they
are routed to and from the NetLink Telephony Gateway. See
Part Number: 72-0065-02-R.doc Page 7

Installation, Configuration, and Administration
device.
2.3 System Timing
The NetLink Telephony Gateways provide SVP when there are four or fewer
Gateways in the system. In this configuration, system timing is done through the IPC
cables between each Gateway. If a NetLink SVP Server is installed in a system with
four or fewer Gateways, the IPC cables are not required. If there are five or more
Gateways in the system, then one or more NetLink SVP Server must be installed to
handle the increased load and additional timing requirements. See NetLink SVP Server: Installation, Configuration, and Administration.
2.4 System Speed
NetLink Wireless Telephones can operate up to 54 Mb/s in 802.11a and 802.11g
modes, and up to 11 Mb/s in 802.11b and b/g-mixed modes. In the b and b/gmixed modes, if certain versions of legacy NetLink Wireless Telephones are used in
the system, all handsets running in that mode will operate at the lowest common
capability.

2.6 System Components
NetLink Wireless Telephones
Employees can carry handsets to place and receive calls as they move throughout the
building. The handsets 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.)
NetLink Telephony Gateway
The 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. The
eight port model supports up to eight telephone lines and handsets and the 16 port
model supports up to 16 telephone lines and handsets. 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
Access points (APs) are supplied by third party vendors, APs provide the connection
between the wired Ethernet LAN and the wireless (802.11) LAN. APs must be
positioned in all areas where NetLink Wireless Telephones will be used. The number
and placement of APs 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 APs that utilize SVP. Refer to the NetLink Wireless Telephone WLAN Compatibility List for a list of APs that support SVP.
Ethernet switch
The Ethernet switch is a component in the wired Ethernet LAN infrastructure.
Switches interconnect multiple network devices, including APs and NetLink
Telephony Gateways. Ethernet switches are required to provide the higher
performance network connections needed to handle combined voice and data traffic.
Router
A router is 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 other’s traffic. The
NetLink Telephony Gateways, the APs, and their associated Ethernet switch must all
Part Number: 72-0065-02-R.doc Page 10
SpectraLink Corporation Installation, Configuration, and Administration
NetLink Telephony Gateway
be on the same subnet because certain network traffic, such as required multicast
events, will not be passed through a router.
NetLink SVP Server
The NetLink SVP Server manages call volume and speed. It is required in any system
when five or more NetLink Telephony Gateways are connected to the LAN. With
40 NetLink Telephony Gateways cabled together, a single NetLink SVP Server
supports 120 simultaneous handset calls. Multiple SVP Servers can be installed to
maximize system capacity.
TFTP server
Required in the system to distribute software to the handsets.
Administrative computer
An administrative computer is 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. The
administrative computer can also be used to periodically upgrade the NetLink
Telephony Gateway software via FTP and the handset and SVP Server software via
TFTP.

3. Installation and Configuration Steps
Installation and configuration 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 APs per the Configuration Note for the AP being
used. This is normally done before the NetLink Telephony Gateway installation, but
should be done before step 3 below.
The first two steps 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.
Conditional:NetLink SVP Server Configuration: If a NetLink SVP Server has been
installed, its configuration would also be done in this step per NetLink SVP Server: Installation, Configuration, and Administration.
4. NetLink Wireless Telephone Configuration: Done by the customer or
SpectraLink per NetLink Wireless Telephone: Configuration and Administration.
5. System Certification: Done after installation to confirm the system is working
properly per NetLink Wireless Telephone: Configuration and Administration.
Part Number: 72-0065-02-R.doc Page 13
SpectraLink Corporation Installation, Configuration, and Administration
NetLink Telephony Gateway
4. Site Preparation
As shown in the system diagram in the previous section, the NetLink Telephony
Gateway is connected to both the Ethernet switch and the wired telephone system;
the NetLink SVP Server is connected to the Ethernet switch only. The specifications
covered here allow for great flexibility in physical placement of the components
within stated guidelines.
4.1 Required Materials
The customer must provide the following equipment.
•Power Outlet(s): Must accept SpectraLink provided AC adapter, one for
each NetLink Telephony Gateway and one for the NetLink SVP Server (if
required). For multiple NetLink Telephony Gateway installations, provide
power strips with sufficient outlets and built-in power switches to enable the
Telephony Gateways to be powered on and off at the same time.
•Cross-Connect Block: Required to connect the PBX ports to the NetLink
Telephony Gateway(s).
•25 Pair Cables: RJ-21 male at NetLink Telephony Gateway end, required to
connect each NetLink Telephony Gateway to the cross-connect blocks.
•Backboard space: The NetLink Telephony Gateway and the NetLink SVP
Server are designed to be wall mounted to ¾” plywood securely screwed to
the wall.
•Screws: Required to mount the NetLink Telephony Gateway and the
NetLink SVP Server (if required) to the wall. Four #8 - ¾” panhead wood
screws (or similar device) are required for each component.
•10BaseT Cables: RJ-45 connector at each NetLink Telephony Gateway.
Connection to Ethernet switch.
•CAT 5 Cable: RJ-45 connector at the NetLink SVP Server. Connection to
Ethernet switch.
•Modem Cable: DB-9 female, null-modem cable. Required for initial setup
of the NetLink Telephony Gateway and SVP Server.

SpectraLink Corporation Installation, Configuration, and Administration
NetLink Telephony Gateway
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.
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 Deploying NetLink Wireless Telephones: Best Practices.
IP Addressing
The NetLink Telephony Gateway, along with each of the handsets 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. Handsets 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.
These worksheets may be started when the system is installed. The information
recorded on them is used in the configuration and continuing administration of the
system.
IP multicast addresses are used by the NetLink i640 Wireless Telephone.
This requires that multicasting be enabled on the subnet used for the
NetLink Wireless Telephones, SVP Server, and Telephony Gateways.
Routers are typically configured with filters to prevent multicast traffic
from flowing outside of specific domains. The wireless LAN can be placed
on a separate VLAN or subnet to reduce the effects of broadcast and
multicast traffic from devices in other network segments.
Part Number: 72-0065-02-R.doc Page 15
SpectraLink Corporation Installation, Configuration, and Administration
NetLink Telephony Gateway
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 or mounted in a standard 19
inch rack mount cabinet with a Rack Mount Kit.
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 switch.
• For the NetLink SVP Server, a maximum distance of 325 feet (100 meters)
from the Ethernet switch.

5. Telephone Interface Configuration
The customer or the customer's wire contractor is responsible for adhering
5.1 Prepare Demarcation (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.
to all local codes for wiring.
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.

SpectraLink Corporation Installation, Configuration, and Administration
NetLink Telephony Gateway
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.
