Circuit Card Description and Installation
Configuration
The trunk type for each unit on the card as well as its terminating impedance
and balance network configuration is selected by software service change
entries at the system terminal and by jumper strap settings on the card.
NT8D14 has a reduced jumper strap setting on the card. There are only three
jumpers, J1.X, J2.X, and J3.X on each channel. Tables 190, 191, and 192
show the functionality of these three jumpers.
