INSTALL ATION & OPERATION • DIP SWITCH SETTINGS
The XAP TH1 has a variety of operational features configurable through
DIP switch settings, including noise burst/auto-adapt, receive AGC
control, auto-answer, auto-disconnect, call progression/loop, and
receive reduction. Default settings (as shipped from the factory) are
denoted by an asterisk “*”.
DIP Switch 1, Noise Burst/Auto-Adapt
In some applications, it may be desirable to adapt the hybrid with a
white-noise burst, rather than allowing the hybrid to adapt automatically
to line conditions. To enable this feature, DIP switch 1 behind the digital
hybrid’s front panel is used to enable/disable the noise burst (Table 1,
below).

DIP Switch 2, 6dB Receive Boost
In some applications, it may be desirable to increase the receive audio
by 6dB. To enable this feature, DIP switch 2 behind the digital hybrid’s
front panel is used to enable/disable the 6dB receive boost (Table 2,
below).
