Closet-mounted (110RA1-12)
The 110RA1-12 terminating-resistor block consists of 12 2-pair circuits and provides the 100-Ohm
termination used for ISDN-BRI circuits.
Figure 35, Terminating-resistor block (110RA1-12),
on page 117 shows the wiring of the 110RA1-12.
Three rows of 110D 4-connector blocks contain resistors and capacitors. The bottom row is designated as
the input row and the top and middle rows are designated as the output rows. The circuit assembly is
mounted on a standard 110A, 100-pair mounting base.
Figure 35: Terminating-resistor block (110RA1-12)
Figure 36, Typical installation of terminating-resistor block, on page 118 shows the wiring connections
for the 110RA1-12 terminal block. The TN556 BRI switch port is terminated to bottom row C.
