Each input is the cathode of the LED on an opto-isolator. The anode is connected through a 
470R resistor to +5VDC. Therefore to activate a control input, short the pin to ground, i.e. pin 
10. Each output is the open collector of a ULN2003 driver chip. Therefore connect the pin 
through load to +5VDC. 

This is the ISDN 2 connector. This must only be connected to an approved ISDN 2 
connection or serious damage may occur.
