Site I/O Extender Cable. Required for use in a BTS not equipped
with the Primary Surge Suppressor.
Site I/O Cabling
The Site I/O interface and cabling are customer–supplied. The cable
between the Site I/O junction box and the Site I/O interface is part of the
Site I/O junction box and is supplied by Motorola. If your BTS uses the
customer–supplied Site I/O Interface instead of the Primary Surge
Suppressor, then you will need to use the Site I/O Extender Cable (Cable
Z). The Site I/O Extender cable is included with this option.
The customer determines the Site I/O interface configuration. The end
result is the correct signals getting to the correct pins on the Site I/O
cable.
