FXS and FXO Interface Modules
Except for the type designation, the FXS and FXO interface modules have
identical telephone interface connectors on the back panel. Each consists of an
RJ-11 modular jack labeled FXS or FXO and a 4-pin terminal block; see
Figure 6-13 below. Both are shielded by a protective cover.
The terminal block is fitted with a female plug. Individual cable leads are
connected to this plug to form a telephone interface cable.
Refer to Figure 6-10 on page 6-7 for more information.
