Abstract:
For use with a digital communication network having a serial communication link over which time division multiplexed (TDM) digital communication signals are conveyable within a plurality of TDM time slots of a digital communication frame, said serial communication link being interfaced with digital communication circuits, a method of testing plural digital communication channels contained within said plurality of TDM time slots of said digital communication frame comprising the steps of:(a) generating a sequence of test frames, each test frame containing a multiplicity of test pattern codes associated with respective ones of said plural digital communication channels within said plurality of TDM time slots of a digital communication frame; and (b) interfacing said sequence of test frames generated in step (a) with said digital communication units by means of said serial network interface and measuring performance of said digital communication circuits by processing frames returned over said serial network interface from said digital communication circuits.
