| 802.1D
802.1Q |
802.1Q defines a layer 2 frame structure that supports VLAN identification and a QoS mechanism usually referred to as 802.1D. |
| 802.1X |
Authentication method for a protocol requiring a network device to authenticate with a back-end Authentication Server before gaining network access. Applicable 9600 Series IP telephones support IEEE 802.1X for pass-through and for Supplicant operation with the EAP-MD5 authentication method. |
| Application - specific |
Specific to a particular “application” running inside the telephone. For example, configuration file downloading, backup and restore of user data, HTTP push, and the Web browser are all internal applications that use the HTTP protocol. Similarly, the RTCP and CNA clients are internal applications that can invoke traceroute. This term does not include Web-page-based “applications” rendered in the Web browser. |
| ARP |
Address Resolution Protocol, used, for example, to verify that the IP Address provided by the DHCP server is not in use by another IP telephone. |
| CLAN |
Control LAN, type of Gatekeeper circuit pack. |
| CNA |
Converged Network Analyzer. |
| DHCP |
Dynamic Host Configuration Protocol, an IETF protocol used to automate IP Address allocation and management. |
| DiffServ |
Differentiated Services, an IP-based QoS mechanism. |
| DNS |
Domain Name System, an IETF standard for ASCII strings to represent IP Addresses. The Domain Name System (DNS) is a distributed Internet directory service. DNS is used mostly to translate between domain names and IP Addresses. Avaya 9600 Series IP Telephones can use DNS to resolve names into IP Addresses. In DHCP, TFTP, and HTTP files, DNS names can be used wherever IP Addresses were available as long as a valid DNS server is identified first.
|
| Gatekeeper |
H.323 application that performs essential control, administrative, and managerial functions in the media server. Sometimes called CLAN in Avaya documents. |
| H.323 |
A TCP/IP-based protocol for VoIP signaling. |
| HTTP |
Hypertext Transfer Protocol, used to request and transmit pages on the World Wide Web. |
| HTTPS |
A secure version of HTTP. |
| IETF |
Internet Engineering Task Force, the organization that produces standards for communications on the internet. |
| LAN |
Local Area Network. |
| MAC |
Media Access Control, ID of an endpoint. |
| QoS |
Quality of Service, used to refer to several mechanisms intended to improve audio quality over packet-based networks. |
| RTCP |
Real-time Transport Control Protocol. |
| RTP |
Real-time Transport Protocol. |
| SRTCP |
Secure Real-time Transport Control Protocol. |
| SRTP |
Secure Real-time Transport Protocol. |
| System - specific |
Specific to a particular type of call server, for example, Avaya Communication Manager (CM). “System-specific signaling” refers to messages specific to the signaling protocol used by the system, for example, H.323 and/or CCMS messages used by CM and IP Office. “System-specific procedures” refers to telephone software procedures that are specific to the call server with which the software is intended to be used. |
| TCP |
Transmission Control Protocol, a connection-oriented transport-layer protocol. |
| TLS |
Transport Layer Security, an enhancement of Secure Sockets Layer (SSL). TLS is compatible with SSL 3.0 and allows for privacy and data integrity between two communicating applications. |
| UDP |
User Datagram Protocol, a connectionless transport-layer protocol. |
| Unnamed Registration |
Registration with Avaya Communication Manager by an IP telephone with no extension. Allows limited outgoing calling. |
| URI & URL |
Uniform Resource Identifier and Uniform Resource Locator. Names for the strings used to reference resources on the Internet (for example, HTTP://....). URI is the newer term. |
| VLAN |
Virtual LAN. |
| VoIP |
Voice over IP, a class of technology for sending audio data and signaling over LANs. |
