Data terminal equipment (DTE):

  • It is terminating equipment for a specific network.
  • It is typically are located on the premises of a customer.
  • Examples: Terminals,Personal computer,Router and Bridges.

Data circuit terminating equipment (DCE):

  • These are carrier owned inter-networking devices.
  • It provides clocking and switching services in a network.

Frame relay has following benefits over a private line network design:

  1. Cost saving
  2. More efficient circuit use
  3. Higher network availability
  4. Higher performance
  5. Virtual circuit vs physical circuits
