Network Requirements

28 Avaya Agent Deskphone 16CC Administrator Guide

The implication for LAN administration depends on the values the user reports and the specific

nature of your LAN, like topology, loading, and QoS administration. This information gives the

user an idea of how network conditions affect the audio quality of the current call. Avaya

assumes you have more detailed tools available for LAN troubleshooting.

TCP/UDP Port Utilization

The Avaya Agent Deskphone 16CC uses a variety of protocols, particularly TCP, UDP, and TLS

to communicate with other equipment in the network. Part of this communication identifies

which TCP or UDP or TLS ports each piece of equipment uses to support each protocol and

each task within the protocol. For additional TCP/UDP port utilization information as it applies to

Avaya Communication Manager, see UDP Port Selection

on page 36. For more information on

TLS, see Security

on page 31.

Depending on your network, you might need to know what ports or ranges are used in the

operation of Avaya Agent Deskphone 16CC telephones. Knowing these ports or ranges helps

you administer your networking infrastructure.

In Figure 2

and Figure 3:

● The box on the left always represents the Avaya Agent Deskphone 16CC telephone.

● Depending on the diagram, the boxes on the right refer to various pieces of network

equipment with which the telephone can communicate.

● Open-headed arrows (for example, ) represent the direction(s) of socket

initialization.

● Closed-headed arrows (for example, ) represent the

direction(s) of data transfer.

Table 4: Parameters in Real-Time

Parameter Possible Values

Received Audio Coding G.711, G.726A, or G.729.

Packet Loss No data or a percentage. Late and out-of-sequence packets are

counted as lost if they are discarded. Packets are not counted

as lost until a subsequent packet is received and the loss

confirmed by the RTP sequence number.

Packetization Delay No data or an integer number of milliseconds. The number

reflects the amount of delay in received audio packets, and

includes any potential delay associated with the codec.

One-way Network Delay No data or an integer number of milliseconds. The number is

one-half the value RTCP or SRTCP computes for the round-trip

delay.

Network Jitter

Compensation Delay

No data or an integer number of milliseconds reporting the

average delay introduced by the jitter buffer of the telephone.
