MULTISERVER 500

The FXS Voice/Fax Interface Module provides
ringing voltage and battery to the attached
telephone equipment. It is normally used to
connect the voice/fax channel directly to a
telephone instrument or to the line side of a Key
Telephone System or fax machine.
NOTE: The FXS voice/fax interface card is not
registered with the FCC, so it cannot be
connected to a public network.
Figure A-1 shows a typical FXS application. For
clarity, the Multiserver 500 is represented by the
FXS voice/fax interface cards.
There are two versions of the FXS Interface Card:
•
MX406C—FXS Standard Loop Start.
This
model meets the safety requirements of North
American regulatory agencies.
•
MX407C—Enhanced FXS Loop Start.
This
model meets the safety requirements of all
European and North American regulatory
agencies.
