Appendix B - Glossary
• 802.1x: An IEEE Standard for port-based Network Access Control (PNAC). It is a part of the IEEE
802.1group of networking protocols. It provides an authentication mechanism to devices wishing to attach
to a LAN or WLAN.
• ACS (Auto Configuration Server): It is responsible for auto-configuration of the Central Processing
Element (CPE).
• Cryptographic Key: It is a piece of variable data that is fed as input into a cryptographic algorithm to
perform operations such as encryption and decryption, or signing and verification.
• DHCP (Dynamic Host Configuration Protocol): It is built on a client-server model, where designated DHCP
server hosts allocate network addresses and deliver configuration parameters to dynamically configured
hosts.
• DHCP Option: It can be configured for specific values and enabled for assignment and distribution to
DHCP clients based on server, scope, class or client-specific levels.
• DNS (Domain Name System): It is a hierarchical distributed naming system for computers, services, or
any resource connected to the Internet or a private network.
• EAP-MD5 (Extensible Authentication Protocol-Message Digest Algorithm 5): It only provides
authentication of the EAP peer to the EAP server but not mutual authentication.
• EAP-TLS (Extensible Authentication Protocol-Transport Layer Security): It provides for mutual
authentication, integrity-protected cipher suite negotiation between two endpoints.
• PEAP-MSCHAPv2 (Protected Extensible Authentication Protocol-Microsoft Challenge Handshake
Authentication Protocol version 2): It provides for mutual authentication, but does not require a client
certificate on the IP phone.
• FAC (Feature Access Code): These special patterns of characters that are dialed from a phone keypad to
invoke particular features.
• HTTP (Hypertext Transfer Protocol): It is used to request and transmit data on the World Wide Web.
• HTTPS (Hypertext Transfer Protocol over Secure Socket Layer): It is a widely-used communications
protocol for secure communication over a network.
• IEEE (Institute of Electrical and Electronics Engineers): It is a non-profit professional association
headquartered in New York City that is dedicated to advancing technological innovation and excellence.
• LAN (Local Area Network): It is used to interconnect network devices in a limited area such as a home,
school, computer laboratory, or office building.
• MIB (Management Information Base): It is a virtual database used for managing the entities in a
communications network.
• OID (Object Identifier): It is assigned to an individual object within an MIB.
• PnP (Plug and Play):
It is a term used to describe the characteristic of a computer bus, or device
specification, whic
h facilitates the discovery of a hardware component in a system, without the need for
physical device configuration, or user intervention in resolving resource conflicts.
• ROM (Read-only Memory): It is a class of storage medium used in computers and other electronic
devices.
