3.5.1 Subscriber lines
The line board terminals are available at the E7 back plane. The line
points are routed to the LCM through six 17-pair flat cables with six 4-
pole plug-in screw terminals at the exchange end and a 34-pole

The subscriber lines are connected to corresponding terminals on the
Line Connection Module board.
All terminals are marked, starting at 1A, 1B, 1C and 1D. The telephone
line pairs are connected to A/B and C/D up to 36C/D if all lines are used.
