9.9.1. Test setup with 4 lines Network DCD ST 4-1
4 Dataline setup: Two symmetrical lines (2 pairs)
Each of the 4 lines has an impedance of= 25 Ω
Bridge (grey): The 25 Ω impedance results by shorting the
135 Ω resistors.
Bridge (CD): Connection for the built-in coupling device
(GDT/ABD) for coupling to lines L1 to L4.

2 Data line setup: One symmetrical lines (1 pair)
Bridge (grey): The 25 Ω impedance results by shorting the
135 Ω resistors of lines L1 and L2.
Bridge (CD): Connection for the built-in coupling device
(GDT/ABD) for coupling to lines L1 and L2.
