Section 2.4  The load impedance (RL and CL) of the terminator side
of an interchange circuit shall have a dc resistance (RL) of not
less than 3000 Ohms, measured with an applied voltage of not
greater than 25 volts in magnitude, nor more than 7000 Ohms,
measured with an applied voltage of 3 to 25 volts in magnitude.  The
effective shunt capacitance (CL) of the terminator side of an
interchange circuit, measured at the interface point, shall not
exceed 2500 picofarads.  The reactive component of the load impedance
shall not be inductive. ...
