Figure 1-58 shows the wiring connections for the 110RA1-12 terminal block. The
TN556 BRI switch port is terminated to bottom row C.
Figure 1-58. Typical installation of terminating resistor block
For point-to-point wiring, the top row connects to the blue station field. The pair
connects from the 110RA1-12 to the standard 4-pair circuit. Pair 1 from the
110RA1-12 connects to Pair 1 of the station field, and Pair 2 connects to Pair 3 of
the station field.
Connect row B (output) to the second terminal common to the multi-point circuit to
accommodate 2 terminal basic multi-point applications.
