802.1Q

802.1Q defines a layer 2 frame structure that supports VLAN identification and a QoS

802.1D

mechanism usually referred to as 802.1D.

 

Authentication method for a protocol requiring a networking device to authenticate

802.1X

 

with a back end Authentication Server before gaining network access. Applicable

 

4600 Series IP telephones support IEEE 802.1X as a Supplicant with the EAP-MD5

 

authentication method.

ARP

Address Resolution Protocol, used to verify that the IP Address provided by the

 

DHCP server is not in use by another IP telephone.

 

Control LAN, type of TN799 circuit pack.

CLAN

DHCP

Dynamic Host Configuration Protocol, an IETF protocol used to automate IP Address

 

allocation and management.

 

Differentiated Services, an IP-based QoS mechanism.

DiffServ

IETF

Internet Engineering Task Force, the organization that produces standards for

 

communications on the internet.

 

Local Area Network.

LAN

LLDP

Link Layer Discovery Protocol. All IP Telephones with an Ethernet interface support

 

the transmission and reception of LLDP frames on the Ethernet line interface in

 

accordance with IEEE standard 802.1AB.

 

Media Access Control, ID of an endpoint

MAC

PAE

Port Access Entity. The protocol entity associated with a port. The PAE supports the

 

protocol functionality associated with the authenticator, supplicant, or both.

 

Quality of Service, used to refer to several mechanisms intended to improve audio

QoS

 

quality over packet-based networks.

RRQ

Read Request packet. A message sent from the 4600 Series IP Telephone to the

 

TFTP server, requesting to download the upgrade script and the application file.

 

SIP Enablement Services. Supports the deployment of duplicated servers with

SES

 

synchronized databases.

SIP

Session Initiation Protocol. An IETF standard protocol for IP communication. SIP

 

enables IP telephony gateways, client endpoints, PBXs, and other communication

 

systems or devices to communicate with each other. SIP mainly addresses the call

 

setup and tear down mechanisms of sessions and is independent of the transmission

 

of media streams between caller and callee. SIP is an alternative to H.323 for VoIP

 

signaling.

 

An entity at one end of a point-to-point LAN segment that is being authenticated by

Supplicant

 

an authenticator at the other end of that link.

TCP/IP

Transmission Control Protocol/Internet Protocol, a network-layer protocol used on

 

LANs and internets.

 

A new feature with Communication Manager 4.0, IP Endpoint Time-to-Service (TTS)

Time-to-

Service

decouples gatekeeper H.323 registration from TCP socket establishment for call

(TTS)

signaling, thus reducing the time for the endpoint to come into service.

TFTP

Trivial File Transfer Protocol, used to provide downloading of upgrade scripts and

 

application files to the IP telephones.

 

User Datagram Protocol, a connectionless transport-layer protocol.

UDP

Unnamed

Registration with Avaya Communication Manager by an IP telephone with no

Registration

extension. Unnamed registration is typically used to limit outgoing calling.

 

Virtual LAN.

VLAN
