McTi-24 T1 Facility Distance Compensation

Each McTi-24 board is equipped with a bank of dip switches (SW2) which allows
compensation for the cable length between the originating T1 facility or repeater and
the McIAS unit. The illustration below indicates the location of this switch bank and
the available cable lengths.
CAUTION: The components on the assembly are sensitive to electrostatic discharge
(ESD). Use an ESD protected environment and procedure when working
with the boards.
