802.1x — an IEEE Standard for port-based Network Access Control (PNAC). It is a part of

the IEEE 802.1 group of networking protocols. It offers an authentication mechanism for

devices to connect to a LAN or WLAN.

ACS (Auto Configuration server) — responsible for auto-configuration of the Central

Processing Element (CPE).

Cryptographic Key — a piece of variable data that is fed as input into a cryptographic

provides authentication of the EAP peer to the EAP server but not mutual authentication.

EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) — 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) — Provides for mutual authentication, but

does not require a client certificate on the IP phone.

FAC (Feature Access Code) — special patterns of characters that are dialed from a

phone keypad to invoke particular features.

HTTP (Hypertext Transfer Protocol) — used to request and transmit data on the World

Wide Web.

HTTPS (Hypertext Transfer Protocol over Secure Socket Layer) — a widely-used

communications protocol for secure communication over a network.
