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
furtherstate that the voltagein a time slot containing a0 must not exceed 5% of thepeak pulse amplitude,except forthe residue
of preceding pulses.
2
Thepower levels specified by the proposed G.703 standards are identical except thatthepoweris tobe measured in 3kHz bands.
3
The all 1s pattern must be a pure all 1s signal, without framing or other control bits.
