Bit 6: Transmit Impedance Termination Off (TIMPOFF).
If this bit is set all the internal Transmit Terminating
Impedance is turned Off.
Bit 3: Transmit Impedance Receive Match (TIMPRM).
This bit selects the internal Transmit Termination
impedance and Receive Impedance Match for E1 mode and T1/J1 mode.
0 = 75 for E1 mode or 100 for T1 mode.
1 = 120 for E1 mode or 110 for J1 mode.
Bit 2 to 0: Template Selection [2:0] (TS[2:0]).
Bits TS[2:0] are used to select E1 or T1/J1 mode, the template,
and the settings for various cable lengths. The impedance termination for the transmitter and impedance match for
the receiver are specified by bit TIMPRM. Short-haul or long-haul operation is selected by the SHLHS bit in the
individual registers
SHLHS

Table 6-14
for bit selection of TS[2:0].
