Extended superframe

From Free net encyclopedia

In telecommunication, an extended superframe is a T-carrier framing technique in which framing requiring less frequent synchronization than the original T-carrier superframe format is provided for D-4 formatting and for on-line, real-time testing of circuit capability and operating condition.

Note: Less-frequent synchronization frees overhead bits for use in testing and monitoring.
