Chapter 1 Introduction

1.1 About NetVision Data Phone

The NetVision Data Phone is a small, lightweight, fully-featured telephone
designed to operate over Spectrum24 802.11 wireless data networks using
technology called Voice- o v er-IP or Vo I P.

The NetVision Data Phone combines the features of the NetVision Phone with
data capabilities in a slightly larger unit. The NetVision Data Phone uses a
thin client to support HTML Web-based applications.

Add a gateway to connect the data network to the traditional telephone PBX
system to give NetVision Data Phones the ability to make and receive calls to
PBX extensions and directly to the Public Switched Telephone Network (PSTN).

The NetVision Data Phone supports:

• ITU standards. NetVision Data Phone employs International
Telecommunications Union (ITU) standard H.323 protocols for real-time

communications over the Internet and corporate Intranets.

• IEEE 802.11 wireless network protocol.

For specific details of the standards the NetVision Data Phone supports, see
Appendix D.

The NetVision Data Phones can make calls through a gateway (gateway
telephony) or over a Spectrum 24 data network (peer-to-peer telephony).
NetVision Data Phones can make calls to several other NetVision telephones
in intercom mode.

NetVision Data Phone Product Reference Guide 1

Introduction

NetVision telephones contain these features:

• Shared usage - Allows users to pick up any phone, log on and receive
the same authorized feature set as on any previously used phone.

• Personal usage - Assigns a phone and PIN to a user exclusively.

• User Profiles - Restrict unauthorized phone usage with a user name and

Personal Identification Number (PIN).

• Name dialing - Name-dialing maps profile names to extensions or IP
addresses. This call list can contain NetVision Phones, NetVision
Data Phones, other IP telephones, PBX extensions and outside
phone numbers.

• Hot Battery Swap - With out first powering down the NetVision Data
Phone, users can exchange a nearly discharged battery with a fresh one
and restart the phone. The phone retains the current user name, PIN
and URL.

• Speed-dialing - The NetVision Data Phone stores phone numbers in
100 two-digit speed-dial locations. Users can store any number.

• Caller ID - The phone displays the caller IP address for an incoming call
from a NetVision Telephone using peer-to-peer telephony.

• Optimized voice quality - A voice-control mechanism converts voice to
digital data packets and back to voice to achieve high-quality audio.

• Multifunction capability - The NetVision Data Phone supports
simultaneous voice, messaging and data functions.

• Rechargeable battery - NetVision Data Phone ships with a rechargeable
Lithium-ion battery.

• NetVision Telephone Administrator - A web-based software program that
builds configuration files for a NetVision Telephone site.

2 NetVision Data Phone Product Reference Guide

1.2 Initial Use of NetVision Data Phones

Symbol ships each Spectrum24 Access Point (AP) and NetVision Data Phone
employing the 802.11 protocol with a default IP address and the ESS ID
parameter set to 101. Charge and install the NetVision Telephone battery.
Connect power and an antenna to an AP and use the NetVision Data Phones
in peer-to-peer telephony.

The NetVision Data Phone User Guide contains basic procedures for using
the NetVision Data Phone and instructions for testing the scanner.

1.3 User profiles

User Profiles contain different levels of access to phone features,
customization functions and privileges. Passwords or personal identification
numbers (PINs) control access to User Profiles.

Use the NetVision Telephone Administrator to create User Profiles and to
download them to phones.

User Profiles:

Introduction

• assign a feature set to a specific user

• customize access to intercom groups

• define class-of-service as peer-to-peer or gateway

• customize access to phone menu options.

1.4 Site Styles

Choose one of two site styles for NetVision Data Phones:

• Shared

• Personal

Each NetVision Data Phone in a Shared site assumes an IP address based on
the logged-on user name. Each NetVision Data Phone in a Personal site has
a permanently assigned IP address.

NetVision Data Phone Product Reference Guide 3

Introduction

1.4.1 Shared Style

In a Shared-style site, each NetVision Data Phone at the site contains the
same list of User Profiles. A PIN provides access for each User Profile. A user
takes any NetVision Data Phone, and logs on with an assigned name and
PIN. The user customizes the User Options.

A user can log on to only one phone at a time in a shared site. The NetVision
Phone handles subsequent attempts to log on differently according to the
setting of the Rem Dup IP parameter. See Appendix A for details.

A Shared site cannot have duplicate PINs.

1.4.2 Personal Style

In a Personal-style site, the NetVision Data Phones have static IP addresses.

The phone requires users to logon with a Name and PIN before it initiates
any calls. Phones in a Personal style can use the Web server to access data
applications before logging on. If the PIN is 0000, the phone automatically
logs the user on when the phone is powered on. The default PIN for Personal
site phones is 0000.

1.5 Names

This feature frees users from memorizing IP addresses or trying to remember
the personnel or department assigned a particular phone extension.

4 NetVision Data Phone Product Reference Guide

Introduction

There are two user classes: general user, a person using the phone
day-to-day; system administrator, the person configuring the phones for
general users.

Profile Name User Class Description

NetVision Data Phone Product Reference Guide 5

Introduction

1.6 Telephony Styles

NetVision Data Phones communicate in two different telephony modes.

• In gateway telephony, each phone performs as an extension of the PBX.
In this telephony style, the phone can dial any extension or outside
number and the POTS telephony gateway routes the calls to the PBX or
to the PSTN directly.

• In peer-to-peer telephony, each phone dials other IP-network telephones
over the Spectrum24 data network. In this telephony style, the phone
dials the IP address of another telephone in a point-to-point connection.
IP (Internet Protocol) routers make voice communications over the
Internet possible.

Only NetVision Data Phones with gateway permission can call traditional
telephones (off-IP-network extensions) through the gateway. NetVision
Telephones with peer-to-peer telephony can call only other H.323 devices
(such as NetMeeting and NetVision telephones) through the IP network.

1.6.1 Gateway Telephony

NetVision Data Phones use the gateway to connect a Spectrum24 wireless
network to a corporate telephone system.

When a user selects a name or dials a traditional PBX extension on a
NetVision Data Phone setup for gateway telephony, NetVision Data Phones
connect the call through the gateway.

The NetVision Telephone Administrator defines extensions corresponding to
NetVision Data Phones. As a network device, each NetVision Data Phone has
a unique IP address. The name directory containing the extensions becomes
part of the configuration downloaded to each NetVision Data Phone. The

6 NetVision Data Phone Product Reference Guide

Introduction

gateway between the Spectrum24 data network and the traditional
telephone system (PBX) maps extensions to non-IP phones, and maps names
to IP address and extensions. When dialing a name or an extension, the
mapping is transparent to the user.

A NetVision Data Phone user can make and receive a call over a standard
Public Switched Telephone Network (PSTN).

The gateway routes an outgoing call to the PSTN. For an incoming call,
the telephone system accepts the call, routes it to the gateway and the
gateway routes the call to the NetVision Data Phones using the extension
to IP address mapping.

NetVision Data Phone Product Reference Guide 7

Introduction

When NetVision Data Phone system administrator assigns NetVision
Data Phones to use gateway telephony, the * and # keys generate DTMF
(dual tone multifrequency) tones normally.

Refer to Appendix C for information on available gateways.

1.6.2 Peer-to-Peer Telephony

Each NetVision Data Phone requires a unique Internet Protocol (IP) address.
In peer-to-peer telephony, NetVision Data Phones use IP addresses in the
same way conventional telephone systems use telephone numbers. The
NetVision Telephone system administrator configures the NetVision Data
Phones with IP subnet masks and router IP addresses.

When a user selects a name from the Names directory on a phone setup for
peer-to-peer telephony, the NetVision Data Phone connects the call over the
data network using IP addresses. Users can also dial IP addresses explicitly,
dialing full or partial IP addresses, to place a call.

When a NetVision Telephone system administrator assigns NetVision Data
Phones to use peer-to-peer telephony, the * and # keys are the IP dialing and
intercom access keys respectively.

In a telephone call between two NetVision telephones, if one NetVision
telephone is restricted to peer-to-peer dialing, the phone makes the call
peer-to-peer telephony.

8 NetVision Data Phone Product Reference Guide

1.7 Intercom Mode

In intercom mode one NetVision Data Phone calls several other NetVision
Data Phones over the Spectrum24 network. In this telephony style, the
phones function like “walkie-talkies,” in that only one user can speak at a
time while other users listen.

The NetVision Telephone Administrator organizes NetVision Data Phones
into intercom groups. Phones in the same group receive intercom calls
together, over the group channel. Any NetVision Data Phone on the system
can initiate a call to any intercom group, but only those phones assigned to
the group receive the call.

The NetVision system administrator can assign NetVision Data Phones to
specific intercom groups.

Intercom telephony uses multicast addressing to call multiple phones
over the Spectrum24 network. Only NetVision telephones participate in
intercom calls.

Introduction

In an intercom call, the user presses a key or button to talk. Some keys
and buttons do not activate the talk function: FCT, END, HOLD and the side­mounted volume buttons. Only one user can talk at a time during an
intercom call.
