802.1Q 
802.1D 

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 networking device to authenticate 
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.

CLAN 

Control LAN, type of TN799 circuit pack.

DHCP 

Dynamic Host Configuration Protocol, an IETF protocol used to automate IP Address 
allocation and management.

DiffServ 

Differentiated Services, an IP-based QoS mechanism.

IETF 

Internet Engineering Task Force, the organization that produces standards for 
communications on the internet.

LAN 

Local Area Network.

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.

MAC 

Media Access Control, ID of an endpoint

PAE 

Port Access Entity. The protocol entity associated with a port. The PAE supports the 
protocol functionality associated with the authenticator, supplicant, or both.

QoS 

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

SES 

SIP Enablement Services. Supports the deployment of duplicated servers with 
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.

Supplicant 

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

Time-to- 
Service 
(TTS)

A new feature with Communication Manager 4.0, IP Endpoint Time-to-Service (TTS) 
decouples gatekeeper H.323 registration from TCP socket establishment for call 
signaling, thus reducing the time for the endpoint to come into service. 

Trivial File Transfer Protocol, used to provide downloading of upgrade scripts and 
application files to the IP telephones.

UDP 

User Datagram Protocol, a connectionless transport-layer protocol.

Unnamed 
Registration 

Registration with Avaya Communication Manager by an IP telephone with no 
extension. Unnamed registration is typically used to limit outgoing calling.

 VLAN

Virtual LAN.
