Notes
1 The pulse template proposed by G.703 standards is shown in Figure 4 and specified in Table 4 The proposed G.703 standards
further state that the voltage in a time slot containing a 0 must not exceed 5% of the peak pulse amplitude, except for the residue
of preceding pulses.
2 The power levels specified by the proposed G.703 standards are identical except that the power is to be measured in 3kHz bands.
3 The all 1s pattern must be a pure all 1s signal, without framing or other control bits.
