Distinguish between virtual circuits and logical channels as follows:
{ A virtual circuit refers to the end-to-end logical link between the calling DTE and the called
DTE.
{ A logical channel refers to the logical link between two directly connected devices (either
between DTE and DCE, or between the ports of two PSEs).
A virtual circuit consists of several logical channels, and each logical channel has a separate
number. A virtual circuit between Router A and Router B can be the one shown in Figure 140
(su
ppose this virtual circuit passes four packet switches in the network).
