Learning About the MobileLAN voice System

This chapter explains the MobileLANvoice system, its components, and the
telephony gateways.

About the MobileLAN voice System

The MobileLAN voice system is the industry’s most advanced Voice-Over-IP wireless
LAN product. By integrating your network with a new or existing wireless LAN, your
on-site mobile users are provided with high-quality mobile voice communications
throughout the workplace.

Read this chapter to learn about the features and operation of the MobileLAN voice
wireless telephone system.

System Architecture

The MobileLAN voice system is Intermec’s wireless LAN-based telephony product.
This system operates in the 2.400-2.483 GHz unlicensed band using direct sequence
(DS) spread spectrum technology, which is compatible with the IEEE 802.11b standard.

The MobileLAN voice system includes MobileLAN voice 2 wireless telephones and
MobileLAN voice telephony gateways. The wireless telephones operate as clients on
the wireless LAN (WLAN) alongside other mobile 802.11b devices. WLAN fixed
radios, called access points, receive IP voice packets from wireless telephones and
forward them to the telephony gateways over the Ethernet LAN. The telephony gateway
connects to the host telephone switch using digital or analog line interfaces.

1

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.

System Components

Your complete system network has several components: telephony gateways, wireless
telephones, access points, switching hubs, and routers.

MobileLAN voice Telephony Gateways

This telephony gateway serves as the connecting point, or gateway, between the LAN
and the existing telephone system. One or more telephony gateways are typically
installed in the telephone equipment room.

Each MobileLAN voice telephony gateway (4-port) supports up to four wireless
telephones. Up to four of these telephony gateways can be connected together to support
a maximum of 16 wireless telephones.

Each MobileLAN voice telephony gateway (16-port) supports up to 16 wireless
telephones. Up to four of these telephony gateways can be connected together to support
a maximum of 64 wireless telephones.

Intermec offers digital telephony gateways that work with the digital ports on most
common brands of telephone systems (PBX or key systems). Intermec also offers
analog telephony gateways that work with analog (loop start) ports on telephone
systems (CO, PBX or key systems).

MobileLAN voice 2 Wireless Telephones

Employees can carry wireless telephones to make and receive calls as they move
throughout the site. The wireless telephones are to be used on the premises; they are not
cellular or satellite phones. They are connected to the facility’s existing telephone
system and to the telephony gateway, and, 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).

Access Points

Access points provide the connection between the wired Ethernet LAN and the IEEE

802.11b HR LAN. They 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 MobileLAN
voice 2 wireless telephones are similar to those of wireless data devices. You can have
up to seven Intermec 21XX universal access points communicating with each telephony
gateway. Each access point can handle up to seven phone calls.

For specific information about your facility’s needs, contact your local Intermec
representative.

1-5

MobileLAN voice System User’s Guide

Switching Hub

A switching hub is a component in the wired Ethernet LAN infrastructure. Hubs
connect multiple network devices including MobileLAN voice telephony gateways and
access points. Switching hubs are required to provide the higher performance network
connections needed to handle combined voice and data traffic. All telephony gateways
in a single MobileLAN voice system must be connected to the same switching hub.

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
telephony gateways, the access points, and their associated switching hub must all be on
the same “side” of the router.

•

a maximum distance of 76.2 m (250 ft) from the host telephone switch for a digital

•

interface and 106.4 m (349 ft) from the switching Ethernet hub.

LAN Requirements

Make sure that you have the necessary network infrastructure and that the system
administrator has provided you with the necessary TCP/IP information.

Network Infrastructure

The telephony gateway connects to your local area network (LAN). To provide
adequate bandwidth and limit collisions, a switching Ethernet hub is required. The
traffic between the telephony gateway and access points should be isolated as much as
possible to avoid additional latency. The telephony gateway and access points must be
on the same logic IP subnet. Intersubnet roaming is not permitted for wireless devices.

Each telephony gateway to be installed requires a 10 Mbps switching Ethernet
connection.

The MobileLAN voice system relies on access points to transmit and receive packets
from wireless telephones. To configure an access point to support MobileLAN voice
system, see the your access point documentation.

IP Addressing

The 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 telephony gateway. Wireless telephones can be set for DHCP or Static
IP addressing. Record IP address assignments on the Wireless Device Planning
Worksheets—one for each 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.

For more information on how to assign IP addresses to the telephony gateways and
wireless telephones, see Chapter 3, “Configuring the MobileLAN voice System.”

wiring.

This section explains how to prepare your telephone system by performing these steps:

1. Prepare and install demarcation blocks.

2. Assign and program telephone ports.

3. Connect telephone lines to demarcation blocks.

Preparing Demarcation Blocks

Caution

If the wiring between the MobileLAN voice system and the telephone system leaves
the building, consult your telephone system manual for instructions on providing
adequate lightning and other overcurrent protection.

All telephony gateways, except the 16-port analog gateway, are intended only for
connection to the isolated side of an on-premise 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 VDC offset.

Conseil

Si le câblage qui relie le système vocal MobileLAN au système téléphonique doit aller
à l'extérieur du bâtiment, consultez le manuel fourni avec le système téléphonique
pour obtenir des instructions sur la façon d’assurer une protection adéquate contre la
foudre et les surintensités.

Toutes les passerelles de téléphonie, à l’exception de la passerelle analogique de 16
ports, sont destinées à être connectées seulement à la paroi isolée d’un
autocommutateur privé (PBX) en place sur les lieux ou à un système d’appareils à
clés.

Les interfaces sont destinées à connecter les ports d’autocommutateurs privés (PBX)
numériques qui fournissent les signaux pour les composants C.A. 5V crête à crête
(max.). Certains ports PBX entraînent un décalage de 48 Vcc.

2-6

Installing the MobileLAN voice System

4-port The telephony gateway is connected to the existing telephone system using

standard RJ-11, 2- or 4-conductor phone line cord. Up to four cords (one for each
wireless telephone) will be needed to connect telephone lines to each telephony
gateway.

16-port The telephony gateway is connected to the existing telephone system using
RJ-21 connections. A telephony gateway is designed to operate with a specific interface
to the telephone system: 2-wire analog or 2-wire digital. The number of demarcation
blocks required for the system depends on the type of telephony gateway to be installed.

Interface Type Intermec Part No. Wire Pairs Number of Blocks

16-port analog 071504 1 1

16-port digital (2-wire) 071505 1 1

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.

2

External Modem

The MobileLAN voice system can also be accessed remotely using an external modem
connected to the RS-232 administration port. The telephone connection to such a
modem is independent of the MobileLAN voice system, but if your site will use an
external modem, this connection should be accounted for while installing the related
wiring.

For more information on modem settings, see Chapter 3, “Configuring the MobileLAN
voice System.”

Installing Telephone Demarcation Blocks or Connections

4-port Install the demarcation blocks or modular connectors used to connect the
telephone system to the telephony gateway.

16-port Install the demarcation blocks used to connect the telephone system to the
telephony gateway 3/4" telephone facility backboard. Although this manual uses 66­blocks as examples, any standard cross-connect blocks are acceptable.

MobileLAN voice System User’s Guide

Assigning and Programming Telephone Ports

Copy the Wireless Device Planning Worksheets that are in Appendix A—one for each
telephony gateway being installed. The wire contractor or installer should inform the
system administrator which telephone port numbers have been designated for the
wireless devices and the remote diagnostics modem line. As the wire contractor or
installer punches down each telephone connection, record the information on the
worksheet to identify the user and extension assigned. Use the worksheets to track
which switch port ID is assigned to which port on the telephony gateway. Post these
worksheets near the demarcation block.

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 telephony gateway, but will be faster if planned in advance
by verifying the parameters and features on the current telephone system and wired
phones.

Connecting Telephone Lines to Demarc Blocks

Copy the Wireless Device Planning Worksheets that are in Appendix A—one for each
telephony gateway being installed. Use the worksheets to track the telephone port
assignments connected to each telephony gateway. As the wire contractor or installer
punches down each telephone connection, record the information on the worksheet to
identify the user and extension assigned. Post these worksheets near the demarcation
block.

Programming the Wireless Telephone Menu

The MobileLAN voice 2 wireless telephone can display a menu of functions that are
activated when you press the Fcn key. The menu should match the feature programming
established in the Feature Programming screen for analog systems or in the PBX for
digital systems. For help, see “Programming Wireless Telephone Features” in the
previous section.

The wireless telephone displays four menus as you repeatedly press the FCN key. Each
menu has four programmable options that are programmed in the Menu Programming
screen, which displays all four menus at once. The default factory settings are for
features most commonly accessed by users of the type of PBX installed with the
wireless telephone system.

All the settings can be customized to conform to the feature programming established at
your site. You should program each telephony gateway with identical menus.

Analog The features defined for the custom menus should match the features
programmed in the Feature Programming screen. For example, if you have defined

ESSID

Select the option that will enable the wireless telephone to communicate with access
points with the correct ESSID (Extended Service Set ID, aka SSID, aka Network Name)
each time it is turned on.

Learn Once This option lets the wireless telephone scan all ESSs for its telephony
gateway. Once it finds its telephony gateway, it retains the ESSID from whichever
access point it associates with at that point. When overlapping wireless systems exist,
the Learn Once feature lets the wireless telephone turn on in any ESSID area and use
only the ESSID established at first learn. This ESSID is retained by the wireless
telephone until the ESSID option is reselected.

Maintaining and Troubleshooting the MobileLAN voice System

About Troubleshooting

Troubleshooting your MobileLAN voice system requires full information about the
components not only of the system, but also of the larger system, which includes both
the host telephone system and the LAN. The MobileLAN voice telephony gateways
provide a “window” into the functioning of the various wireless components via the
System Status menu.

Normally, troubleshooting sequences proceed from the simple to the complex. To
perform these procedures, you should have a thorough understanding of the
configuration of the system.

You should also have additional information about your system that can be provided by
a map, blueprint, or diagram of the facility that clearly shows hardware components
including access point positions and wireless telephone assignments. Also, you should
have the Wireless Telephone Assignment Worksheets.

Understanding the Telephone Line Status Screen

Each telephony gateway associates wireless telephones with lines from the host
telephone system (PBX) as configured in the system setup. The Telephone Line Status
screen provides operational information about each wireless telephone connection. This
information corresponds with the configuration information set up from the Telephone
Line Configuration option on the main menu.

When the telephony gateway needs to be maintained, current call activity can be
checked on this screen to determine the level of service interruption a shutdown will
involve.

The wireless telephone computes the “rate” for the TX and RX statistics by
calculating the number to increase quickly when retries begin. As retries lessen to zero
and the transmissions become more reliable, the number peaks and decreases slowly.

Wireless Telephone Problems

MobileLAN voice 2 wireless telephones can exhibit transmission problems in several
ways. They can cease functioning properly, display error messages, or display incorrect
data. When using and troubleshooting wireless telephones, consider the following
problem sources to determine the best method of approaching any specific situation.

Access Point Problems

Most, but not all, wireless telephone audio problems have to do with access point range,
positioning and capacity. Using the wireless telephone to help you perform a site survey
as described in “Using Site Survey Mode” in Chapter 3 can isolate the access point
causing these types of problems. If you suspect the wireless telephone has the problem,
conduct a parallel site survey with a wireless telephone that is known to be properly
functioning.

In Range/Out of Range

Service will be disrupted if you move outside the area covered by the access points.
Service is restored if you move back within range. If a call drops because you move out
of range, the wireless telephone will recover the call if you move back into range within
a few seconds.

4

Capacity

In areas of heavy use, the call capacity of a particular access point may be filled. If this
happens, you will hear three chirps from the wireless telephone. You can wait until
another user terminates a call, or you can move within range of another access point and
try the call again. If you are on a call and move into an area where capacity is full, the
system attempts to find another access point. Due to range limitations, this may be the
same as moving out of range.

Transmission Obstructions

Prior to system installation, the best location for access points for optimum transmission
coverage was determined. However, small pockets of obstruction may still be present,
or obstructions may be introduced into the facility after system installation. This loss of
service can be restored by moving out of the obstructed area, or by adding access points.

4-25

MobileLAN voice System User’s Guide

Configuration Problems

Certain problems are associated with improper configuration of either the telephony
gateway or the wireless telephone.

For instance, no extension displayed or wrong extension displayed on the wireless
telephone has no effect on its operation, but serves to easily identify it. Other
configuration problems, like having incorrect menu items or inability to connect or
access telephone system features, affect the wireless telephone’s functioning.

Configuration problems are generally corrected by changing the configuration at the
telephony gateway or on the wireless telephone. For help, see Chapter 3, “Configuring
the MobileLAN voice System.” There may also be incorrect programming of the PBX
or access point. For help, see the documentation for your product.

Infrastructure Problems

Calls ringing on the wrong wireless telephone or multiple wireless telephones not
working are likely to be caused by faulty installation. The wires that connect the
demarcation block to the telephony gateway could be installed incorrectly.

Contact your wireless LAN and/or PBX vendor for more information about
troubleshooting infrastructure problems.

Dial Tone Problems

A dial tone problem exists if the wireless telephone has no dial tone, or if you are unable
to hear the other party’s voice, hear echo, or hear dead air.

To troubleshoot dial tone problems

1. Turn on the wireless telephone in an active service area. If the wireless telephone
does not get a dial tone in an active area, continue with the steps below.

If the no dial tone problem is limited to a certain area, see the “Access Point
Problems” earlier in this chapter.

2. Verify that the No Svc message turns off a few seconds after the wireless telephone
is turned on.

3. Swap the battery with a battery from a functional wireless telephone, turn the
wireless telephone back on, and check for dial tone. If this corrects the problem,
charge the battery pack that was removed.

4. Turn the wireless telephone off then on again, and then test again for dial tone. If
OK, place a call and determine voice quality.

5. While maintaining an active call, walk through several access point coverage areas.
If fluctuation occurs, see “Access Point Problems” earlier in this chapter.

4-26

Maintaining and Troubleshooting the MobileLAN voice System

6. Check for alarms on the gateway (System Status). If there are alarms, see
“Understanding the Error Status Screen” earlier in this chapter.

7. Make sure the wireless telephone’s gateway port is connected to a working phone
line. Check the line at the demarcation block. You may need to contact your vendor
to perform this check.

8. Check the cabling between the telephony gateway and the demarcation block, and
between the demarcation block and the telephone system ports.

9. Move the wireless telephone to a different port location and test again.
