DLP-G23 Install Alarm Wires on the Backplane (ANSI Only)
Step 1 Using 100-ohm shielded BITS clock cable pair #22 or #24 AWG (0.51 mm² or 0.64 mm²) twisted-pair
T1-type wires, wrap the alarm wires on the appropriate wire-wrap pins according to local site practice.
Ground the shield of the BITS Input cable at the BITS end. For BITS Output, wrap the ground shield of
the BITS cable to the frame ground pin (FG1) located below the column of BITS pins.
Figure 1-21 shows alarm pin assignments for the AIC-I in the Release 3.4 or higher ONS 15454
backplane, and Figure 1-22 calls out the external alarm pins on that backplane.
