Name/Description Function
J1 Jumper Selects internal or external balancing network (A = internal, B = external)
TP3 Test point Line High (orange)
TP4 Test point Line Low (orange)
TP5 Test point Receive High (green)
TP6 Test point Receive low (yellow)
TP7 Test point Send High (red)
TP8 Test point Send Low (white)
18.2.3.1 SELECTING THE BALANCING NETWORK
Jumper J1 is used to select either the internal (50 Ohm resistive) balancing impedance or an external, user
supplied, balancing impedance. Placing the jumper in the A position selects the internal impedance.
Selecting the B position selects the external impedance.
