3.24 WAVEFORM SHAPER / LINE BUILD OUT
three ways of manipulating the waveform shaper can be selected before
the data is transmitted:
3.24.1 PRESET WAVEFORM TEMPLATE
3.24.1.1 T1/J1 Mode
which meets T1.102 and G.703, and it is measured in the far end as
shown in Figure 33.
templates are provided corresponding to five grades of cable length.
The selection is made by the PULS[3:0] bits. In J1 applications, the
PULS[3:0] bits should be set to ‘0010’. The details are listed in Table 60.

According to the various cables, configured by the PULS[3:0] bits,
• Preset Waveform Template;
• Line Build Out (LBO) Filter (T1 only);
• User-Programmable Arbitrary Waveform.
In T1/J1 applications, the waveform template is shown in Figure 32,
In T1 applications, to meet the template, five preset waveform
