Overview
+ + + + + + +
+ + + + + +
+ Integrated Services Digital Network + (ISDN) is a network that provides end-to-end digital connectivity + to support a wide range of services including voice and data + services.

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.

+

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.

+

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.

+

Students completing this module should be able to:

+
    +
  • Define the ISDN standards used + for addressing, concepts, and signaling
    • +
  • Describe how ISDN uses the + physical and data link layers
    • +
  • List the interfaces and + reference points for ISDN
    • +
  • Configure the router ISDN + interface
    • +
  • Determine what traffic is + allowed when configuring DDR
    • +
  • Configure static routes for DDR
    • +
  • Choose the correct encapsulation + type for DDR
    • +
  • Be able to determine and apply + an access list affecting DDR traffic
    • +
  • Configure dialer interfaces
    • +
+
