templates in detail for reference. For preset pulse templates, scaling up/
down against the pulse amplitude is not supported.
Table-2 Transmit Waveform Value For E1 75 Ohm
SCAL[5:0] = 100001 (default), One step change of this value of SCAL[5:0]
results in 3% scaling up/down against the pulse amplitude.

Table-3 Transmit Waveform Value For E1 120 Ohm
Table-4 Transmit Waveform Value For T1 0~133 ft
SCAL[5:0] = 100001 (default), One step change of this value of SCAL[5:0]
results in 3% scaling up/down against the pulse amplitude.
SCAL[5:0] = 110110
results in 2% scaling up/down against the pulse amplitude.
1. In T1 mode, when arbitrary pulse for short haul application is configured,
users should write ‘110110’ to SCAL[5:0] bits if no scaling is required.
