Avaya 3631 [14/31] Tcp udp port utilization

3631 Wireless Telephone Administrator Guide 14

Three incorrect PIN attempts in a row disables the SIM card. These attempts may occur

over successive startups.

A disabled SIM card may be re-enabled through the PIN Unblocking Key (PUK) process.

In this process, a PUK code is required to re-enable the SIM card. A user must enter the

PUK code into phone to re-enable the SIM. After 10 unsuccessful PUK code entry

attempts, the SIM card is permanently disabled and must be replace

Note

The PUK code is delivered with phone, printed on paper enclosed in the phone box.

Avaya does not have a record of the PUK code, so make sure the PUK code is stored

securely.

TCP/UDP Port Utilization

Like most network equipment, the Avaya 3631 Wireless Telephones use a variety of

protocols, particularly TCP and UDP, to communicate with other equipment in that

network - numerous different types of servers, routers, other telephones, etc. Part of this

communication identifies which TCP and/or UDP ports each piece of equipment uses to

support each protocol and each task within protocol

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

Avaya 3631 Wireless Telephones` operation. Knowing these ports or ranges allows you

to appropriately administer your networking infrastructure. In this case, you will find the

following material useful.

In Figure1, Figure 2, and Figure 3:

• The box on the left always represents the Avaya 3631 Wireless telephone

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

equipment with which the telephone can (or will) communicate.

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

initialization.

• Closed-head arrows (for example, ) represent the direction(s)

of data transfer.

• The text the arrows point to identifies the port or ports that the Avaya 3631 Wireless

Telephones support for the specific situation. Brackets identify ranges when more

than one port applies. In addition, the text indicates any additional qualifications or

clarification. In many cases, the ports used are the ones called for by IETF or other

standards bodies.
