FXO Interface Strapping
The FXO interface is designed to meet regulatory agency requirements unique
to selected countries (such as Spain, France, and Germany). This module
contains special straps that implement the requirements of each country.
There are 13 movable straps located on the FXO interface module, E1 through
E13. The following four figures show the locations of these straps. The straps
function as follows:
• Straps E1 through E5 are reserved for factory use only. They must not
be altered by the user
• Five different strapblocks (E6/E7, E8/E9, E10/E11, E13/E14, and
E15/E16) are used to select the country of operation (see Figure 6-16,
Figure 6-17, and Figure 6-18)
• Strap E12 is reserved for factory use only. It must not be altered by the
user
