The jack box is on the Reperforator.  The TU-170 connects to the TTY.

The manual suggests that the jack box is used to connect the 
Reperforator to the line units for transmit/receive on landline.  Since 
I will only use the Reperforator to punch tape locally, I don't think I 
need the jack box.  I THINK that means I don't need to provide the 115 
DC volts, which would mean not needing the rectifier at all.
