The H.323 Recommendation assumes the transmission path between the telephony users passes through at least one local area network (LAN), such as an Ethernet or a token ring.

As shown in Figure 9-2, the H.323 encompasses end-to-end connection between H.323 terminals and other terminals and through different kinds of networks.
