For a full signal description of the Site I/O cable, refer to Table 5-14 in
the “Site I/O, Span Line, RGPS and Modem Cabling For Sites Equipped
With Primary Surge Suppressor” procedure.
The pin number and wire color are based on the Site I/O
cable. The pin number corresponds to pins on the Site I/O
junction box connectors.
