Receive Bipolar Tip for Transceiver 1 to 16. The differential inputs of RTIPn
and RRINGn can provide partially internal impedance matching for E1 75 Ω , E1
120 Ω , T1 100 Ω , or J1 110 Ω . The user can turn off internal termination via the
LIU Receive Impedance and Sensitivity Monitor register (LRISMR).
Receive Bipolar Ring for Transceiver 1 to 16. The differential inputs of RTIPn
and RRINGn can provide partially internal impedance matching for E1 75 Ω , E1
120 Ω , T1 100 Ω , or J1 110 Ω . The user has the option of turning off internal
termination via the LIU Receive Impedance and Sensitivity Monitor register
(LRISMR).
Receive Tip External Termination 1 to 16. These pins are used with RTIPn to
provide the ability to switch out the external termination resistor, thereby
providing high impedance to the line. Useful for redundancy applications.
Resistor Reference. This pin is used to calibrate the internal impedance match
resistors of the receive LIUs. This pin should be tied to V
resistor.
