1. In internal impedance matching mode, for E1/75
cable impedance, the PULS[3:0] bits (TCF1, 06H) should be set to ‘0000’. In external impedance matching mode, for E1/75 cable
impedance, the PULS[3:0] bits should be set to ‘0001’.

SCAL specifies a scaling factor to be applied to the amplitude of the user-programmable arbitrary pulses which is
to be transmitted if needed. The default value of SCAL[5:0] is ‘100001’. Refer to 3.3.3.3 User-Programmable Arbi-

DS1 0dB LBO. One step change of this value results in 2% scaling up/down against the pulse amplitude.
= 010001: Default value for DS1 -7.5 dB LBO. One step change of this value results in 6.25% scaling up/down
against the pulse amplitude.
= 001000: Default value for DS1 -15.0 dB LBO. One step change of this value results in 12.5% scaling up/down
against the pulse amplitude.
= 000100: Default value for DS1 -22.5 dB LBO. One step change of this value results in 25% scaling up/down
against the pulse amplitude.
= 100001: Default value for E1 75
and 120 . One step change of this value results in 3% scaling up/down
against the pulse amplitude.
