DS1 Transmitter Pulse Template
The DS1 pulse shape template is specified at the DSX
(defined by CB119 and ANSI T1.102) and is illustrated
in Figure 31. The device also meets the pulse template
specified by ITU-T G.703 (not shown).

During DS1 operation, the TTIP and TRING pins will perform as specified in Table 47.
1. In accordance with the line circuitry described (see Line Circuitry on page 94).
2.Total power difference.
3.Measured in a 2 kHz band around the specified frequency.
4.Using Lucent transformer 2795B and components in Table 55.
5.Below the power at 772 kHz.
