4.3 Multiplexing

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.

4.3.1 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.

4.3.2 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.

4.4 VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel
Identifier (VCI) numbers assigned to you. 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 appendix for more information.
