    Testing encompasses both fibre-optic and galvanic cable loop-backs depending on their actual positions in the communication network (see Figure 89). Loop-back testing with X.21 galvanic interface requires special procedures and equipment. Contact your local Hitachi Power grids representative for more details. Procedure: Block the trip circuits.
