11.2 E3 Pulse Mask
This function captures and analyzes E3 (34.368Mbps) pulse shape. The purpose of maintaining the correct pulse shape is to
reduce inter-symbol interference – if the logic 1s and 0s cannot be detected by the receiver correctly, bit and code errors will
result.
The pulse amplitude and overall shape are superimposed and compared with ITU-T G.703 pulse conformance template.
Telecommunications signals require specific load impedance for pulse mask compliance testing to be accurate. When high
frequency pulses are transmitted down a transmission line, a portion of the pulse will be reflected when and wherever it
encounters an impedance mismatch. The reflection is proportional to the impedance mismatch (i.e., the greater the mismatch, the
greater the reflection of the pulse).

11.3 E1 APS Testing
This function measures the Automatic Protection Switching (APS) limits of the network. APS applies the Multiple E1 Links and
enables network elements to re-route traffic to a backup circuit in the event of network failure or problems.
