DESCRIPTION

EXAMPLE

 

 

 

TCP/IP Setup

 

 

IP Address

Enter the (LAN) IP address of your Prestige in dotted decimal

192.168.1.1

 

notation

 

IP Subnet Mask

Your Prestige will automatically calculate the subnet mask based on

255.255.255.0

 

the IP address that you assign. Unless you are implementing

 

 

subnetting, use the subnet mask computed by the Prestige.

 

 

 

 

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to save your configuration, or press [ESC] at any time to cancel.

3.7VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers supplied by your telephone company. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the Appendices for more information.

3.8Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.

3.8.1 VC—based Multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit, for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.

3.8.2 LLC—based Multiplexing

In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs.
