101 Glossary G Gatekeeper: An H.323 entity that provides address translation, control access, and sometimes bandwidth management to the LAN for H.323 endpoints. Gateway: 1. A functional unit that interconnects two computer networks with different network architectures. A gateway connects networks or systems of different architectures. A bridge interconnects networks or systems with the same or similar architectures. 2. A network that connects hosts. 3. An H.323 entity that provides real-time, two-way...

102 MultiVOIP 400/800 User Guide ISDN (Integrated Services Digital Network): An International telecommunications standard for transmitting voice, video and data over a digital communications line. ISDN is a world-wide telecommunications service that uses digital transmission and switching technology to support voice and digital data communications. Frame relay was partially based on ISDNs data link layer protocol (LAPD). Frame relay can be used to transmit across ISDN services offering...

103 Glossary M Management Information Base (MIB): A database of network management information used by the Common Management Information Protocol (CMIP) and the Simple Network Management Protocol (SNMP). Megacom: An AT&T service with a normal WATS line (typically T1) between the customer premise and the AT&T serving class 4 CO are the customers responsibility. MegaLink: BellSouths leased T1 service. Message: Associated with such terms as packet, frame, and segment. 1. In information theory, an...

104 MultiVOIP 400/800 User Guide Outage: The measure of the time during which a circuit is not available for use due to service interrupt. Outage is the complement of circuit availability (100% minus % available = % outage). Out-of-band: Signaling that is separated from the channel carrying the information (i.e., the voice/data/video signal is separate from the carrier signal). Dialing and various other supervisory signals are included in the signaling element. Contrast In-band signaling. Out of...

105 Glossary Q Quality of Service (QoS): Guarantees network bandwidth and availability for applications. Quantizing: The process of analog-to-digital conversion by assigning a range, from the contiguous analog values, to a discrete number. R Random Access Memory (RAM): A computers primary workspace. All data must be stored in RAM (even for a short while), before software can use the processor to manipulate the data. Before a PC can do anything useful it must move programs from disk to RAM. When you...

106 MultiVOIP 400/800 User Guide Signaling: The process of establishing, maintaining, accounting for, and terminating a connection between two endpoints (e.g., the user premises and the telco CO). Central office signals to the user premises can include ringing, dial tone, speech signals, etc. Signals from the users phone can include off-hook, dialing, speech to far-end party, and on-hook signals. In-band signaling techniques include pulse and tone dialing. With common channel signaling, information is...

107 Glossary Terminal: 1) The screen and keyboard device used in a mainframe environment for interactive data entry. Terminals have no box, which is to say they have no file storage or processing capabilities. 2) An H.323 endpoint that provides for real-time, two-way communications with another terminal, gateway, or H.323 MCU. An H.323 terminal must provide audio and may also provide video and/or data. Terminal Adapter (TA): An ISDN DTE device for connecting a non-ISDN terminal device to the ISDN...
