LPAC Cabling
The LPAC module provides the communication interface from the ETIB
and C-CCP to the LPA through the trunking backplane. The LPAC
interface board is contained in a protective housing which is mounted on
the RF cabinet frame behind the ETIB module. See Figure H-3,
Figure H-8 and Figure H-9 for connecting cables and connector
locations.
The LPAC is located internally to the frame as shown in Figure H-1.
