2. Inject a 1.2 kHz tone from a balanced 600 ohm
source, at the level determined by the type of line
used, into TXS+ and TXS- of J2 located on the back
of the Repeater (see Figure 7-14).
Leased Line/Direct Connect (default)
-12 dBm (194 mV RMS)
Microwave/T1 (optional)
-28 dBm (31 mV RMS)
3. Adjust R242 on the MAC to obtain -10 dBm (245
mV RMS) measured at J100/J103.
