2.9.5 T1 Transition Board Facility Distance Compensation (McTi-24MR only)

Each McTi-24MR T1 Transition Board is equipped with jumpers (JP1, JP2 and JP3)
which allow compensation for the cable length between the originating T1 facility or
repeater and the McIAS unit. The illustration of the transition board in Section 2.9.2.1
shows the locations of these jumpers.
CAUTION: The components on the assembly are sensitive to electrostatic discharge
(ESD). Use an ESD protected environment and procedure when working
