	Authentication method for a protocol requiring a network device to authenticate with a
802.1X
	back-end Authentication Server before gaining network access. Applicable 1600
	Series IP telephones support IEEE 802.1X for pass-through and for Supplicant
	operation with the EAP-MD5 authentication method.
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.
	Code-excited linear-predictive. Voice compression requiring only 16 kbps of
CELP
	bandwidth.
CLAN	Control LAN, type of Gatekeeper circuit pack.
	Converged Network Analyzer, an Avaya product to test and analyze network
CNA
	performance.
DHCP	Dynamic Host Configuration Protocol, an IETF protocol used to automate IP address

	Avaya 1600 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.
	H.323 application that performs essential control, administrative, and managerial
Gatekeeper
	functions in the media server. Sometimes called CLAN in Avaya documents.
H.323	A TCP/IP-based protocol for VoIP signaling.
	Hypertext Transfer Protocol, used to request and transmit pages on the World Wide
HTTP
	Web.
HTTPS	A secure version of HTTP.
	Internet Engineering Task Force, the organization that produces standards for
IETF
	communications on the internet.
LAN	Local Area Network.
	Link Layer Discovery Protocol. All IP telephones with an Ethernet interface support
LLDP
