Installing and Programming IVR SECTION 1 SECTION 2 DESCRIPTION IVR is an Interactive Voice Response system that can be used as a man-machine interface unit. The IVR plays prompts, guiding a caller to make selections of different available choices using a touchtone telephone key pad (DTMF tones). The IVR's flexibility gives users the ability to program the prompts to guide the caller by using a scripting language. These scripts can be generated either manually or by a supplied IVR Visual Editor. The scripts can gain access to any Open Database Connectivity (ODBC) compliant database, using simple Structured Query Language SQL ( ) commands. The databases can either be present on the CD-PVAA or on a separate database server. When the database is located on a separate server, the IVR accesses such a database using ODBC connections over the Ethernet network. Examples of IVR applications include access to automated banking, order tracking, reminder generators, etc. CD-PVAA with the IVR application is a blade with 8-or 16-voice communication ports, dependent on the number of registered license. It can be installed in any interface slot in the SMB8000 system. IVR FEATURES 1Installing and Programming IVR Features Include: Inbound Calling Create menus View reports Access to more customer databases Enhanced scripting options Enhanced XML interfaces Time-of-day and day-of-week-based transfers Complete tracking of caller navigation IVR Installation and Setup Manual 1-1

Glossary DHCP Term Terms listed in the following table are used in this manual. Table 3-1 Glossary of Terms Definition Dynamic Host Configuration Protocol provides a framework for passing configuration information to hosts on a TCP/IP network. See also IP and TCP. 3Glossary Dynamic Host Configuration Protocol Gateway Interactive Voice Response Internet Internet Protocol See DHCP. A gateway provides entrance and exit into a communications network. In technical terms, a gateway is an electronic repeater device that intercepts and steers electrical signals from one network to another. A gateway includes a signal conditioner which filters out unwanted noise and controls characters. In data networks, a gateway normally has a node on both networks to connect two otherwise incompatible networks. As an example, PC LAN users may need a gateway to gain access to a mainframe computer since the mainframe does not speak the same language (protocols) as the PCs on the LAN. In this case, a gateway on a data network performs code and protocol conversions. See also LAN, Media Gateway and Network. See IVR. The Internet is a collection of networks whose users communicate with each other. Each communication carries the address of the source and destination networks and the particular machine within the network associated with the user or host computer at each end. This address is called the IP address. See also Network and IP Address. See IP. IVR Installation and Setup Manual 3-1
Issue 1.0 SMB8000 Table 3-1 Glossary of Terms Term Definition IP IP Address IVR LAN Local Area Network Media Gateway The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. When data is sent or received (e.g., an e-mail or a Web page), the message is divided into little chunks called packets. Each of these packets contains both the sender's Internet address and the receiver's address. Any packet is sent first to a gateway computer that understands a small part of the Internet. The gateway computer reads the destination address and forwards the packet to an adjacent gateway that in turn reads the destination address and so forth across the Internet until one gateway recognizes the packet as belonging to a computer within its immediate neighborhood or domain. That gateway then forwards the packet directly to the computer whose address is specified. See also Gateway, Internet, IP Address and Packet. Internet Protocol Address is typically a 32-bit number that identifies each sender or receiver of information that is sent in packets across the Internet. When an HTML page is requested or an e-mail is sent, the Internet Protocol part of TCP/IP includes the sender s IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator that was requested or in the destination e-mail address. At the other end, the recipient can see the IP address of the Web page requestor or the e- mail sender and can respond by sending another message using the IP address it received. An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. On the Internet itself - that is, between the router that move packets from one point to another along the route - only the network part of the address is looked at. See also Packet, TCP and Router. Interactive Voice Response (IVR) is a software application that accepts both voice and touch-tone keypad input. The responses to the input is in the form of voice, fax and other media. Usually IVR is part of a larger application that includes a database. Local Area Network is a short distance data communications network. LANs are used to link computers and peripheral devices (such as printers) together under standard control. See also Network. See LAN. A media gateway is any device, such as a circuit switch, IP gateway, or channel bank that converts data from the format required for one type of network to the format required for another. See also Gateway. 3-2 Glossary
SMB8000 Issue 1.0 Table 3-1 Glossary of Terms Term Definition Network ODBC Open Database Connectivity Packet Protocol A PSTN Public Switched Telephone Network Router SQL Structured Query Language In information technology, a network is a series of points or nodes interconnected by communication paths. Networks can interconnect with other networks and contain subnetworks. Open Database Connectivity (ODBC) is an open standard application programming interface for accessing a database. By using ODBC statements in a program, files can be accessed in different databases, including Access, dbase, DB2 Excel and text. See Open Database Connectivity. A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. Protocol A is used for automatic TCP/IP configuration to provide status and dynamic address allocation and management. See also TCP and IP. See Public Switched Telephone Network. PSTN (public switched telephone network) is the aggregation of circuit-switching telephone networks. For the IVR, the PSTN provides circuit switching that supports voice, fax and modem. When used on the Internet, a router is a device or computer software that determines the next network point to which a packet should be forwarded toward its destination. A router is connected to at least two networks and decides which direction to send each information packet based on the state of the networks to which it is connected. A router is located at any gateway (where one network meets another), including each Internet point-of-presence. A router is often included as part of a network switch. See also Gateway and Network. Refer to Structured Query Language. SQL (Structured Query Language) is a standard interactive and programming language for getting information from and for updating a database. SQL supports both ANSI and ISO standard, however, many database products support SQL with proprietary extensions to standard languages. The queries are in the form of a command language that allows users to select, insert, update and search the database. IVR Installation and Setup Manual 3-3
Issue 1.0 SMB8000 Table 3-1 Glossary of Terms Term Definition TCP Transport Control Protocol (TCP) is a set of rules (called protocols) that are used along with the Internet Protocol (IP) to send data in the form of message units between computers over the Internet. While IP takes care of handling the actual delivery of the data, TCP takes care of keeping track of the individual units of data (called packets) that a message is divided into for efficient routing through the Internet. TCP cannot support the real time services such as interactive video and conferencing because TCP is rather a slow protocol, requiring three-way hand shaking.
