It is not uncommon for remote sites to
access the WAN core layer by using WAN technologies other than
dedicated links. As shown the figure, Frame Relay and ISDN are two such alternatives. If
a remote site is small and has low demand for access to services in
the corporate network, ISDN would be a logical choice for this
implementation. Perhaps another remote site cannot get access to
dedicated WAN links from its service provider, but has access to Frame
Relay.

number of acronyms and abbreviations, sometimes
called TLAs (or Three Letter Acronyms). This
exercise will highlight some of the more common
acronyms and terminology used.
