Chapter 5 WAN Setup 5.6.1 LLC-based Encapsulation 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. 5.6.2 VC-based Encapsulation 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. 5.7 WAN Connection Type and Encapsulation Mode This is the second WAN setup add (or edit) screen. Use this screen to configure WAN connection type and encapsulation mode. Figure 24 Advanced Setup > WAN > Add (2) 60 P-663HN-51 User's Guide
