A T-interface is used for basic rate access in an Integrated Services Digital Network (ISDN) environment. It is a User-Network Interface reference point that is characterized by a four-wire, 144 kbit/s (2B+D) user rate.

Other characteristics of a T-interface are:

  • it accommodates the link access and transport layer function in the ISDN architecture
  • it is located at the user premises
  • it is distance sensitive to the servicing Network termination 1
  • it functions in a manner similar to that of the Channel Service Units (CSUs) and the Data Service Units (DSUs).
