3. Enable Switches Jumper
This jumper is used to enable or disable the externally accessible audio gain and side tone
switches. This is useful for countries that restrict end user accessible adjustments to the
audio levels over their Telco networks. This is a 3 pin header with a movable shunt
connector. When the shunt is placed across pins 1 and 2, the SIDTN, XSET2, XSET1 and
RSET switches are disabled and serve no function. In this state there is no side tone and
the transmit and receive gains are set to 0 DB (the default settings). When the shunt is
placed across pins 2 and 3, the SIDTN, XSET2, XSET1 and RSET switches are enabled
and will function as described in the SWITCH SETTINGS section of this document.
