2.9.1 Pulse Shape

Normalized and isolated AMI output pulses fit the T1/E1 pulse templates in

Figures 2-35 and 2-37 when measured in accordance with the test circuits in

Figures 2-36 and 2-38. Table 2-15 through Table 2-22 list the pulse template

corner points. An isolated pulse is defined as a 1 followed by seven 0s for T1, and

a 1 followed by three 0s for E1. The pulse templates shown in Figures 2-35 and

2-37 come from ANSI T1.403-1995, ITU-T G.703, and ANSI T1.102-1993.
