Bit 6: Transmit Impedance Termination Off (TIMPOFF).
If this bit is set, all the internal transmit terminating
impedance is turned off.
Bits 5 and 4: Reserved
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. Note: If the part number ends with –120,
then the default is 120 and 75 when set for El mode only.

Bits 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. See
Table 5-11
for bit selection of TS[2:0].
