Description

This test ensures the transmitter output level and pulse shape meet the
required specifications at all PDH/DSn rates. The Transmitter output is
connected to an oscilloscope and the waveshape compared with the
predefined masks stored in the oscilloscope memory. The signal levels are
also measured using the oscilloscope.
