1.15 ONS 15454 ANSI Alarm, Timing, LAN, and Craft Pin
Connections
Pin connections are provided on the ONS 15454 ANSI backplane. For information about
ONS 15454 ETSI connections, see the “1.8 ONS 15454 ETSI Front Mount Electrical Connection”
section on page 1-32.
The ONS 15454 ANSI has a backplane pin field located at the bottom of the backplane. The backplane
pin field provides 0.045 inch
2
(29 mm
2
) wire-wrap pins for enabling external alarms, timing input and
output, and craft interface terminals. This section describes the backplane pin field and the pin
assignments for the field. Figure 1-54 on page 1-57 shows the wire-wrap pins on the backplane pin field.
Beneath each wire-wrap pin is a frame ground pin. Frame ground pins are labeled FG1, FG2, FG3, etc.
Install the ground shield of the cables connected to the backplane to the ground pin that corresponds to
the pin field used.
Note The AIC-I requires a shelf assembly running Software R3.4.0 or later. The backplane of the ANSI shelf
contains a wire-wrap field with pin assignment according to the layout in Figure 1-53 on page 1-56. The
shelf assembly might be an existing shelf that has been upgraded to Software R3.4 or later. In this case,
the backplane pin labeling appears as indicated in Figure 1-54 on page 1-57, but you must use the pin
assignments provided by the AIC-I card as shown in Figure 1-53 on page 1-56.
