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 1-57 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.
