10CHAPTER 1: VCX SYSTEM SECURITY

Ending UDP Port Number

To calculate the ending port number in the UDP range, use this formula:

UDP ending port number = (UDP Start Port) +(Number of Ports -1)

Formula Element

Explanation

 

 

UDP Start Port

See the calculation in “Starting UDP Port Number”, earlier in

 

this section.

 

 

Number of Ports

The default for IP Messaging is 144 ports. During the IP

 

Messaging installation process, you are given an opportunity

 

to change this value. If you changed the value, use the

 

number that you chose.

 

Add the number of ports used by the V7111 and V7122

 

gateways on your system. See “Analog and Digital Gateway

 

Ports”, later in this section.

 

 

Analog and Digital The VCX system includes V7111 Analog Gateways for connection to the Gateway Ports Public Swithced Telephone Network (PSTN) through analog phone lines or

to analog telephones and fax machines. It also uses digital gateways to connect to the PSTN (T1 and E1 spans).

The V7111 Analog Gateways use these ports:
