Chapter 1 – Description and
Specifications
Introduction
The MVP2410/3010 are rack-mount models; and the MVP24-48/30-60 are add-on expansion cards that double
the capacity of the base units without adding another chassis. These voice-over-IP products have fax
capabilities. The 2410 models adhere to the North American standard of T1 trunk telephony using digital 24-
channel time-division multiplexing, which allows 24 phone conversations to occur on the T1 line simultaneously.
The 3010 models use E1 lines, usually of the ISDN Primary Rate Interface type (ISDN-PRI).
Figure 1-1: MVP 2410/3010 Chassis
When expansion is needed, your MVP2410/3010 can be field-upgraded into a dual unit by installing the MVP24-
48 or 30-60 kit, which is essentially a second MultiVOIP motherboard that fits in an open expansion-card slot. The
upgraded dual unit then accommodates two T1/E1 lines.
Computer Requirements
The computer on which the MultiVOIP’s 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.
However, this PC does not need to be connected to the MultiVOIP 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.

Chapter 1: Description & Specifications
Interface
While the web interface appears differs slightly, its content and organization are essentially the same as that of
the Windows interface (except for logging). These will be addressed in the following chapters.
Front Panel LEDs
The MVP2410/3010 and MVP24-48/30-60 both use a common main circuit board or motherboard. Consequently
the LED indicators are the same for both.
Active LEDs. The MVP2410/3010 front panel has two sets of identical LEDs. In the MVP2410/3010 as shipped
(that is, without an expansion card), the left-hand set of LEDs is functional whereas the right-hand set is not.
When the MVP2410/3010 has been upgraded with an MVP24-48 or 30-60 kit, the right-hand set of LEDs will also
become active.
Figure 1-2: MVP2410/3010 LEDs
LED Descriptions. The MVP2410/3010 has four sets of LEDs plus a lone LED at its far right end. As viewed
from the front of the MVP2410/3010, it is the two left groups that are active and present feedback about the
operation of the unit. If an MVP24-48 or 30-60 expansion card is added, the two LED groups on the right become
operational with respect to the second T1/E1 connection.
Front Panel LED Definitions

Chapter 2 – Installing and Cabling the
MultiVOIP
Introduction
The MVP2410 and 3010 MultiVOIP are somewhat heavy units. When these units are to be installed into a rack,
two able-bodied persons should participate. Please read the safety notices before beginning installation.
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.
Safety Warnings Telecom
1. Never install telephone wiring during a lightning storm.
2. Never install a telephone jack in wet locations unless the jack is specifically designed for wet locations.
3. This product is to be used with UL and UL listed computers.
4. Never touch un-insulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
5. Use caution when installing or modifying telephone lines.
6. Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of
electrical shock from lightning.
7. Do not use a telephone in the vicinity of a gas leak.
8. To reduce the risk of fire, use only a UL-listed 26 AWG or larger telecommunication line cord.

Chapter 2: Installing and Cabling the MultiVOIP
Rack Mounting Instructions for MVP2410/3010
The MultiVOIPs can be mounted in an industry-standard EIA 19-inch rack enclosure.
Safety Recommendations for Rack Installations
Ensure proper installation of the unit in a closed or multi-unit enclosure by following the recommended installation
as defined by the enclosure manufacturer. Do not place the unit directly on top of other equipment or place other
equipment directly on top of the unit. If installing the unit in a closed or multi-unit enclosure, ensure adequate
airflow within the rack so that the maximum recommended ambient temperature is not exceeded. Ensure that the
unit is properly connected to earth ground by verifying that it is reliably grounded when mounted within a rack. If a
power strip is used, ensure that the power strip provides adequate grounding of the attached apparatus.
When mounting the equipment in the rack, make sure mechanical loading is even to avoid a hazardous condition.
The rack used should safely support the combined weight of all the equipment it supports.
Ensure that the mains supply circuit is capable of handling the load of the equipment. See the power label on the
equipment for load requirements (full specifications for MultiVOIP models are presented in chapter 1 of this
manual).
This equipment should only be installed by properly qualified service personnel. Only connect like circuits -
connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits and TN (Telecommunications Network)
circuits to TN circuits.
19-Inch Rack Enclosure Mounting Procedure
Attaching the MultiVOIP to a rack-rail of an EIA 19-inch rack enclosure will certainly require two persons.
Essentially, the technicians must attach the brackets to the MultiVOIP chassis with the screws provided, as shown
in Figure 2-1, and then secure unit to rack rails by the brackets, as shown in Figure 2-2. Because equipment
racks vary, screws for rack-rail mounting are not provided. Follow the instructions of the rack manufacturer and
use screws that fit.
1. Position the right rack-mounting bracket on the MultiVOIP using the two vertical mounting screw holes.
2. Secure the bracket to the MultiVOIP using the two screws provided.
3. Position the left rack-mounting bracket on the MultiVOIP using the two vertical mounting screw holes.
4. Secure the bracket to the MultiVOIP using the two screws provided.
5. Remove feet (4) from the MultiVOIP unit.
6. Mount the MultiVOIP in the rack enclosure per the rack manufacture’s mounting procedure.

Chapter 2: Installing and Cabling the MultiVOIP
Cabling Procedure for MVP2410/3010
Cabling your MultiVOIP entails making the proper connections for power, command port, phone system (T1/E1
line connected to PBX or telco office), and Ethernet network. Figure 2-3 shows the back panel connectors and
the associated cable connections. The following procedure details the steps necessary for cabling your
MultiVOIP.
1. Connect the power cord to a live AC outlet, and then connect it to the MultiVOIP’s power receptacle
shown at top right in figure below.
Figure 2-3: Cabling for MVP2410/3010
2. Connect the MultiVOIP to the PC (the computer that will hold the MultiVOIP software) using the RJ-45 to
DB9 (female) cable provided with your unit. Plug the RJ-45 end of the cable into the Console port of the
MultiVOIP and connect the other end (the DB9 connector) to the PC serial port you are using (typically
COM1 or COM2). See Figure 2-3.
3. Connect a network cable to the Ethernet connector on the back of the MultiVOIP. Connect the other end
of the cable to your network.
4. If you intend to configure the MultiVOIP remotely using the MultiVOIP Windows GUI, connect an RJ-11
phone cable between the Command Modem connector (at the rear of the MultiVOIP) and a receptacle
served by a telco POTS line. See Figure 2-4.
The Command Modem is built into the MultiVOIP unit. To configure the MultiVOIP remotely using its
Windows GUI, you must call into the MultiVOIP’s Command Modem. Once a connection is made, the
configuration process is identical to local configuration with the Windows GUI.

Figure 2-4: MVP2410/3010 connections for ground & modem
5. Ensure that the unit is properly connected to earth ground by verifying that it is reliably grounded when
mounted within a rack.
This can be accomplished by connecting a grounding wire between the chassis grounding screw (see
Figure 2-4) and a metallic object that will provide an electrical ground.
6. Turn on power to the MultiVOIP by setting the power switch on the right side panel to the ON position.
Wait for the Boot LED on the MultiVOIP to go off before proceeding. This may take a couple of minutes.

Chapter 3 – Software Installation
Introduction
Configuring software for your MultiVOIP entails three tasks:
Loading the software onto the PC (this is “Software Installation” and is discussed in this chapter).
Setting values for telephony and IP parameters that will fit your system (a detailed discussion of this is found in
Chapter 4).
Establishing “phonebooks” that contain the various dialing patterns for VOIP calls made to different locations (a
detailed discussion of this is found in Chapter 5).
Loading MultiVOIP Software onto the PC
The software loading procedure does not present every screen or option in the loading process. It is assumed
that someone with a thorough knowledge of Windows and the software loading process is performing the
installation.
1. Be sure that your MultiVOIP has been properly cabled and that the power is turned on.
2. Insert the MultiVOIP CD into your CD-ROM drive. The CD starts automatically. It may take a few
moments for the Multi-Tech CD installation window to display.
Figure 3-1: MVP 2410/3010 splash screen
3. When the Multi-Tech Installation CD dialog box appears, click the Install Software icon.
4. An install screen appears. Select the install appropriate for your model.

7. On the next screen you can select the COM port that the command PC will use when communicating with
the MultiVOIP unit. After software installation, the COM port can be re-set in the MultiVOIP Software (from
the sidebar menu, select Connection | Settings to access the COM Port Setup screen or use keyboard
shortcut Ctrl + G).
Note: If the COM port setting made here conflicts with the actual COM port resources available in the
command PC, the “Error in Opencomm handle” message will appear when the MultiVOIP program is
launched. If this occurs, you must reset the COM port.
8. A completion screen will appear.
Figure 3-4: Completion
Click Finish.
9. When setup of the MultiVOIP software is complete, you will be prompted to run the MultiVOIP software to
configure the VOIP.

Chapter 3: Software Installation
Setup Overview
With the software now installed, you are ready to get your MultiVOIP set up and working. There are a few
necessary settings that need to be entered in the configuration software to achieve this and they are noted in the
action lists for the categories below. The following chapters will cover all aspects in detail, but here we will cover
the basic configuration needed to start VOIP communications. Below you will find the list of categories requiring
information to be set before VOIP communication will be ready.
⇒Ethernet/IP
⇒Voice/Fax
⇒Call Signaling
⇒T1/E1/ISDN
⇒Regional
⇒Phone Book
This setup process is followed by the Save & Reboot step which is very important.

Chapter 3: Software Installation
Call Signaling
There are three choices for Call Signaling: H.323, SIP and SPP. It is best to select one of these as the protocol to
be used, rather than mixing them. Single Port Protocol (SPP) is a non-standard protocol created by Multi-Tech
that allows dynamic IP allocation. Generally, the default settings will work for most users and the individual
parameters may be changed if the need arises. Additional details for all settings are found in Chapter 4.
