Chapter 1 – Description and Specifications

Introduction

The MultiVOIP GSM provides wireless voice communications over the Internet or an Intranet. By integrating
wireless connectivity into your existing data network, you can realize substantial savings on inter-office long
distance toll charges. The MVPGSM has “phone books,” which are directories set up to simulate dialing and
connecting as though the call was in the local area.

Front Panel LEDs

LED Types. The MVPGSM has two types of LEDs on the front panel:

(1) general operation LED indicators (for power, booting, and Ethernet functions), and

(2) channel operation LED indicators that describe the voice traffic and performance for each channel.

Bars (0-3)

After power up, the Boot LED will be on briefly while the MultiVOIP GSM is booting. It lights
whenever the MultiVOIP GSM is booting, saving a configuration or receiving a firmware upgrade.
LNK. Link/Activity LED. This LED is lit if Ethernet connection has been made. It is off when the link
is down (i.e., when no Ethernet connection exists). While the link is up, this LED will flash off to
indicate activity.

SPD. Speed indicator LED: this is lit when link speed is 100MB/s and off when it is 10MB/s.

Channel-Operation LEDs (one set for each channel)

Line Status.

• Continuous “on” state indicates that the channel is connected.

• Flashing states:

• 600 ms on / 600 ms off – searching for network, no SIM card or authentication in progress

• 75 ms on / 3000 ms off – IDLE mode; registered on network but no call in progress

• 75 ms on / 75 ms off / 75 ms on / 3000 ms off – GPRS PDP contexts activated

• Off state. Channel is off (not ready) or in sleep mode.

Ring Indicator. This LED will light when an incoming Ring Signal is detected.

There are three LEDs for each channel. If no LEDs are lit, there is not enough signal strength to
maintain the wireless connection reliably. If at least one LED is lit, there is enough signal to
maintain connection with Low signal strength. If the left two LEDs are lit, a Medium signal strength
is present. If all three LEDs are lit, a High signal strength is present.

Computer Requirements

The computer on which the MVPGSM configuration program is installed must meet these requirements:

• must be IBM-compatible PC with MS Windows operating system;

• must have an available COM port for connection to the MultiVOIP GSM.

However, this PC does not need to be connected to the MultiVOIP GSM permanently. It only needs to be
connected when local configuration and monitoring are done. Nearly all configuration and monitoring
functions can be done remotely via the IP network using a web browser.

Chapter 1: Description & Specifications

PTCRB Requirements Note

There cannot be any alteration to the authorized antenna system. The antenna system must be the same type
with similar in-band and out-of-ban radiation patterns and maintain the same specifications.

FCC Requirements Note

The antenna gain, including cable loss, must not exceed 3.0 dBi at 1900 MHz / 1.6 dBi at 850 MHz for mobile
operating configurations and 7.0 dBi at 1900 MHz / 2.3 dBi at 850 MHz for fixed mounted operations, as
defined in 2.1091 and 1.1307 of the rules for satisfying RF exposure compliance.

Load Balancing

The MVPGSM uses round robin load balancing to ensure that one or more SIMs are not used excessively while
others go largely ignored during times of light traffic. The channels are treated as a list and once a channel is
used, it goes to the bottom of the list and the next channel comes to the top of the list and is ready for use. In
the case of a MVPGSM-2, once channel 1 has been used, the next call will be routed through channel 2, then
back to channel 1, and so on. When Hunting is enabled, load balancing is done automatically.

Chapter 2 – Installation and Activation

Introduction

The MultiVOIP GSM is equally usable as tabletop unit or mounted in a location with good reception. The initial
setup is best performed before any mounting is done.

Safety Warnings

Lithium Battery Caution

A lithium battery on the voice/fax channel board provides backup power for the timekeeping capability. The
battery has an estimated life expectancy of ten years. When the battery starts to weaken, the date and time
may be incorrect. If the battery fails, the board must be sent back to Multi-Tech Systems for replacement.

Warning: There is danger of explosion if the battery is incorrectly replaced.

General Safety

The MultiVOIP GSM is designed for, and intended to be used in fixed applications. “Fixed” means that the device
is physically secured at one location and is not able to be easily moved to another location.

Caution: A separation distance of at least 20 cm (8 inches) is normally maintained between the transmitter’s

antenna and the body of the user or nearby persons. The MVPGSM is not designed for or intended to
be used in portable applications within 20 cm. (8 inches) of the body of the user.

RF Interference Issues

It is important to follow any special regulations regarding the use of radio equipment due in particular to the
possibility of radio frequency (RF) interference. Please follow the safety advice given below carefully.

• Switch OFF your MVPGSM in hospitals and any other place where medical equipment may be in use.

• Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting

operations are in progress.

• There may be a hazard associated with the operation of your MVPGSM close to inadequately protected

personal medical devices such as hearing aids and pacemakers. Consult the manufacturers of the

medical device to determine if it is adequately protected.
Operation of your MVPGSM close to other electronic equipment may also cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.

Unpacking Your MultiVOIP GSM

When unpacking your MultiVOIP GSM, check to see that all of the items are included in the box. If any box
contents are missing, contact Multi-Tech Tech Support at 1-800-972-2439.

GSM Instructions

Step 1 – Activate Your Wireless Account

Select a wireless network provider and follow their directions to activate your account and receive your SIM
cards.

Phone Numbers

Every channe

by your wireless service provider or it may be on the SIM card or both. Wireless provider

implementations may vary.

Step 2 – Installing the SIM Cards

The MVPGSM requires the power supply connection to begin operation. It also requires a SIM card (Subscriber
Identity Module) to operate on a GSM network. To install the modem, do the following:

1. Turn the unit off and disconnect the power cord. Remove the three highlighted screws from the back as

shown below.

l will have its own unique phone number. The phone number may simply be given to you

2. Slide the cover forward and up to remove it.

3. Insert the SIM cards into the units at the front of the MVPGSM.

4. Verify that the SIM cards fit into their holders properly and then replace the cover. Attach the power cord.

Step 3 – Check Signal Strength

Turn the unit on and verify that the Power LED is lit and that the Boot sequence is finished (Boot LED is no
longer active), then wait for the Link Status (LS) LED to show that the MVPGSM channel is registered on the
wireless network (flashing 75 ms on and 3 seconds off). Once registered, the Signal Strength LEDs should be
referenced for the strength of signal in its current location.

Caution: Before final placement or mounting, ensure that the wireless signal strength is strong enough for the

chosen area. If no LEDs are lit, there is insufficient signal strength for proper operation. If one or
more are lit, then there is good signal strength and operation will not be impaired. Finding a location
with the strongest signal strength is desirable.

Chapter 4 – Configuring Your MultiVOIP GSM

Introduction

There are two methods of configuring your MultiVOIP GSM; one is through a web interface, and the other is
through the Windows software interface. There are several necessary parameters that must be set for the
MultiVOIP GSM unit to operate properly, with some additional settings that are optional. You must know the IP
address that will be used, the IP mask, the Gateway IP, and the Domain Name Server information. The
MultiVOIP GSM must be configured locally at first, but changes to this initial configuration can be done locally or
remotely. Local configuration is done through a connection between the “Console” port of the MultiVOIP GSM
and the COM port of the computer; the MultiVOIP GSM configuration software is used for this.

This chapter will explain the setup portion of the software pertaining to the list below, while Chapter 5 will cover
the Phone Book setup and Chapter 6 will discuss the Statistics options and overall maintenance of the MultiVOIP
GSM.

Chapter 4: Configuring your MVPGSM

How to Navigate Through the Software

The MultiVOIP GSM software is launched from the Start button and is found in the All Programs area under the
title of MultiVOIP GSM x.xx (where x represents version number). The top option is “Configuration” – choose
this.

Within the software, there are several ways to arrive at the parameter that you want to use: through the left­hand panel, from the drop-down menu, clicking a taskbar icon (if available) or a keyboard shortcut (if available).
Once the initial settings are entered, you may choose to configure the MultiVOIP GSM through a Web browser
instead.

Web Browser Interface

The MultiVOIP GSM web browser interface gives access to the same commands and configuration parameters as
are available in the MultiVOIP GSM Windows interface except for logging functions. When using the web
browser interface, logging can be done by email (the SMTP option).

Set up the Web Browser interface (Optional). After an IP address for the MultiVOIP GSM unit has been
established, you can choose to configure the unit by using the MultiVOIP GSM web browser interface. If you
want to do configuration work using the web browser interface, you must first set it up:

• Set IP address of MultiVOIP GSM unit using the MultiVOIP GSM Configuration program (the Windows

interface). The default IP address is 192.168.3.143.

• Save Setup in Windows interface.

• Close Windows interface.

• Install Java program from MultiVOIP GSM product CD (on first use only).

• Open web browser.

• Browse to IP address of MultiVOIP GSM unit.

• If a username and password have been set up, enter them when prompted.

• Set the browser to allow pop-ups. The MultiVOIP GSM Web interface makes use of pop-up windows.

• The configuration screens in the web browser will have the same content as their counterparts in the

software; only the presentation differs.

Ethernet/IP

This section covers the Ethernet settings needed for the MultiVOIP GSM unit. In each field, enter the values that
fit the network to which the MultiVOIP GSM will be connected to. For many of the settings, the default values
will work best – try these settings first unless you know you definitely need to change a parameter.

The Ethernet/IP Parameters fields are described in the tables and text passages below.

draft is an extension of the 802.1D bridging standard. 802.1D determines how prioritization
will operate within a MAC-layer bridge for any kind of media. The 802.1Q draft for virtual
local-area-networks (VLANs) addresses the issue of prioritization for Ethernet networks in
particular.

802.1p enacts this Quality-of-Service feature using 3 bits. This 3-bit code allows data switches
to reorder packets based on priority level. The descriptors for the 8 priority levels are given
below.

802.1p PRIORITY LEVELS

LOWEST PRIORITY

1 – Background: Bulk transfers and other activities permitted on the network, but should not

affect the use of network by other users and applications.

2 – Spare: An unused (spare) value of the user priority.
0 – Best Effort (default): Normal priority for ordinary LAN traffic.
3 – Excellent Effort: The best effort type of service that an information services organization

would deliver to its most important customers.

4 – Controlled Load: Important business applications subject to some form of “Admission

Control”, such as preplanning of Network requirement, characterized by bandwidth
reservation per flow.

5 – Video: Traffic characterized by delay < 100 ms.
6 – Voice: Traffic characterized by delay < 10 ms.
7 - Network Control: Traffic urgently needed to maintain and support network

infrastructure.

Diff Serv PHB (Per Hop Behavior) values pertain to a differential prioritizing system for IP packets as
handled by Diff Serv-compatible routers. There are 64 values, each with an elaborate technical
description. These descriptions are found in TCP/IP standards RFC2474, RFC2597, and, for present
purposes, in RFC3246, which describes the value 34 (34 decimal; 22 hex) for Assured Forwarding
behavior (default for Call Control PHB) and the value 46 (46 decimal; 2E hexadecimal) for Expedited
Forwarding behavior (default for VOIP Media PHB). Before using values other than these default
values of 34 and 46, consult these standards documents and/or a qualified IP telecommunications
engineer.

MultiVOIP GSM unit has an FTP Server function so that firmware and other
important operating software files can be transferred to the VOIP via the network.

Enables Domain Name System function where computer names are resolved using
a worldwide distributed database.

Internet Domain Name System specifying information on available servers for a
specific protocol and domain, as defined in RFC 2782. Newer internet protocols like
SIP, STUN, H.323, POP3, and XMPP may require SRV support from clients. Client
implementations of older protocols, like LDAP and SMTP, may have been enhanced
in some settings to support SRV.

Voice/Fax

Setting the Voice Parameters. The Voice/Fax section needs to be set for each channel to be used. However, once
you have established a set of Voice parameters for a particular channel, you can apply this entire set of Voice
parameters to another channel by using the Copy Channel button and its dialog box. To copy a set of Voice
parameters to all channels, select “Copy to All” and click Copy.

The majority of the settings should be left at their default settings as changes may introduce problems with
audio quality. In each field, enter the values that fit your particular setup.

The Voice/FAX Parameters settings are described in the tables below.
