Voice / Fax over IP Networks 100 Chapter 1 Introduction to the MultiVOIP
Chapter 1 - Introduction to the MultiVOIP Chapter 1 - Introduction to the MultiVOIP The MultiVOIP 100 (Model MVP120) allows analog voice and fax communication over a traditional IP network. Multi-Tech’s new voice/fax gateway technology allows voice and fax communication to be transmitted, with no additional expense, over your existing communications Internet, which has traditionally been data-only.
Chapter 1 - Introduction to the MultiVOIP Preview of This Guide This guide describes the MultiVOIP and tells you how to make the cable connections, install the software, and configure it. The information contained in each chapter is as follows: Chapter 1 - Introduction to the MultiVOIP This chapter describes the MultiVOIP features, a typical application, and the front and back panels.
Chapter 1 - Introduction to the MultiVOIP Typical Application Before VOIP (Voice Over IP) technology existed, a sales office used a data connection to the Internet and a voice connection to the public telephone network. Now, with VOIP, the two networks can be tied together. To accomplish this a Sales Office MultiVOIP is connected between the public telephone network and the data network as shown in the typical application below.
Chapter 1 - Introduction to the MultiVOIP The H.323 Gatekeeper acts as the central point for all calls within its zone and provides call control services to registered endpoints. If you choose the proprietary phone book, you establish a master-slave relationship where the master MultiVOIP maintains the phone directory and downloads the directory to each slave unit. The Gatekeeper/Proprietary Phone Book selection is chosen from the Phone Directory Database dialog box.
Chapter 1 - Introduction to the MultiVOIP you use the same port number. The Gatekeeper administrator will then enter your information into the Gatekeeper data base. This concludes the preregisteration. You can enter your alias address information into the Add/Edit Phone Entry dialog box. For example, if you were setting up the corporate MultiVOIP, you could enter the following information for the Voice/Fax Channel: Channel 1 of the corporate MultiVOIP uses extension 101.
Chapter 1 - Introduction to the MultiVOIP Again, the corporate MultiVOIP IP Address needs to be added. The port number is 1720. This adds phone number 101 of the corporate MultiVOIP to the proprietary database. After you have added Channel 1, you need to include Channel 1 at the remote branch office.
Chapter 1 - Introduction to the MultiVOIP Similarly, if a person at the Remote Sales office picked up extension 201 and dialed extension 101, the MultiVOIP at the Sales Office would generate a second dial tone and the person at the Remote Sales office would then dial any extension at the Sales Office, or the person could then dial a 9, for example, and get an outside line of the Sales Office Public Switched Telephone network.
Chapter 1 - Introduction to the MultiVOIP Back Panel Description The cable connections for the MVP120 are made at the back panel. Connectors include Power, Ethernet, Command Port (RJ-45), and FXO Voice/Fax Channel. The cable connectors are shown and defined belos.

Voice / Fax over IP Networks 100 Appendixes
Appendix A - TCP/IP Description Appendix A - TCP/IP Description TCP/IP (Transmission Control Protocol/Internet Protocol) is a protocol suite and related applications developed for the U.S. Department of Defense in the 1970s and 1980s specifically to permit different types of computers to communicate and exchange information with one another. TCP/IP is currently mandated as an official U.S. Department of Defense protocol and is also widely used in the UNIX community.
Appendix A - TCP/IP Description UDP, described in RFC 768 (ftp://ds.internic.net/rfc/rfc768.txt) provides an end-to-end datagram (connectionless) service. Some applications, such as those that involve a simple query and response, are better suited to the datagram service of UDP because there is no time lost to virtual circuit establishment and termination. UDP’s primary function is to add a port number to the IP address to provide a socket for the application.
Appendix A - TCP/IP Description Internet Protocol (IP) IP is the Internet standard protocol that tracks Internetwork node addresses, routes outgoing messages and recognizes incoming messages, allowing a message to cross multiple networks on the way to its final destination. The IPv6 Control Protocol (IPV6CP) is responsible for configuring, enabling, and disabling the IPv6 protocol modules on both ends of the point-to-point link.

Glossary Centrex: A multi-line service offered by operating telcos which provides, from the telco CO, functions and features comparable to those of a PBX for large business users. See also "Private Branch Exchange", "Exchange". Channel: A data communications path between two computer devices. Can refer to a physical medium (e.g., UTP or coax), or to a specific carrier frequency.
Data Communications Equipment (DCE): Any device which serves as the portal of entry from the user equipment to a telecommunications facility. A modem is a DCE for the phone network (PSTN) that is commonly on site at the user’s premises. Packet Switched Networks have another level of DCE which is most often located at a central office. Data Link Connection Identifier (DLCI): One of the six components of a frame relay frame.
Glossary EIA: The Electronics Industries Association is a trade organization in Washington, DC that sets standard for use of its member companies. (See RS-232, RS-422, RS530.) Encapsulation: A technique used by network-layer protocols in which a layer adds header information to the protocol data unit from the preceding layer. Also used in "enveloping" one protocol inside another for transmission. For example, IP inside IPX. Endpoint: The clients in an H.323 network.
Foreign Exchange Station (FXS): See FX, FXO. To generate a call from the computer telephony system to the POTS set, a FXS connection must be configured. Forward Explicit Congestion Notification (FECN): A bit that tells you that a certain frame on a particular logical connection has encountered heavy traffic. The bit provides notification that congestion-avoidance procedures should be initiated in the same direction of the received frame. See also BECN (Backward Explicit Congestion Notification).
Glossary Inter Exchange Carrier (IEC): The long distance company (LE) who's central office provides the point of reference for T1 access. Any common carrier authorized by the FCC to carry customer transmissions between LATAs. Internet: Refers to the computer network of many millions of university, government and private users around the world. Each user has a unique Internet Address. Internet Address (IP Address): A unique 32-bit address for a specific TCP/IP host on a network.
Local Access and Transport Area (LATA): A post-divestiture geographical area generally equivalent to a Standard Metropolitan Statistical Area. At divestiture, the territory served by the Bell system was divided into approximately 161 LATAs. The Bell Operating Companies (BOCs) provide Intra-LATA services. Local Exchange Carrier (LEC): The local phone company which provides local (i.e., not long distance) transmission services. AKA "telco".
Glossary Network: A group of computers connected by cables or other means and using software that enables them to share equipment, such as printers and disk drives to exchange information. Node: Any point within a network which has been assigned an address. O Object-Orientated: A method for structuring programs as hierarchically organized classes describing the data and operations of objects that may interact with other objects.
PRI (Primary Rate Interface): Used on ISDN. In North America, and Japan, PRI is one 64Kbps D channel and 23 B channels. Elsewhere, it is one D channel and 30 B channels. PRI is the ISDN equivalent of a T-1 circuit. Primitive: An abstract representation of interaction across the access points indicating that information is being passed between the service user and the service provider. The OSI Reference Model defines four types of primitives: Request, Indication, Response and Confirm.
Glossary Router: A device that connects two networks using the same networking protocol. It operates at the Network Layer (Layer 3) of the OSI model for forwarding decisions. Routing Information Protocol (RIP): A distance vector-based protocol that provides a measure of distance, or hops, from a transmitting workstation to a receiving workstation. RS-232-C: An EIA standard for a serial interface between computers and peripheral devices (modem, mouse, etc.). It uses a 25pin DB-25, or a 9-pin DB-9 connector.
Glossary T Tariff: The rate/availability schedule for telephone and ISDN services from a regulated service provider. TCP/IP: A set of communication protocols that support peer-to-peer connectivity functions for both local and wide area networks. TCP/IP was developed by the US Department of Defense to link dissimilar computers across dissimilar and unreliable LANs. T Carrier: The generic name for a digitally multiplexed carrier system.
Glossary Trunk: A communication line between two switching systems or offices. Central office trunks connect a PBX to the switching system at the central office. A tie trunk connects two PBXs. TSR (terminate and stay resident): A software program that remains active and in memory after its user interface is closed. Similar to a daemon in UNIX environments. Tunneling: Encapsulation data in an IP packet for transport across the Internet.
