+ (ISDN) is a network that provides end-to-end digital connectivity
+ to support a wide range of services including voice and data
+ services.</font><p><font face="Arial" size="2">ISDN allows
+ multiple digital channels to operate simultaneously through the
+ same regular phone wiring used for analog lines, but ISDN
+ transmits a digital signal rather than analog. Latency is much
+ lower on an ISDN line than on an analog line.</font></p>
+ <p><font face="Arial" size="2">Dial-on-demand routing (DDR) is a
+ technique developed by Cisco that allows the use of existing
+ telephone lines to form a wide-area network (WAN), instead of
+ using separate, dedicated lines. Public switched telephone
+ networks (PSTNs) are involved in this process.</font></p>
+ <p><font face="Arial" size="2">DDR is used when a constant
+ connection is not needed, thus reducing costs. DDR defines the
+ process of a router connecting using a dialup network when there is
+ traffic to send, and then disconnecting when the transfer is
+ complete.</font></p>
