Setting the V.54 Delay
When using ASM-10/8 as a tail-end to a DDS network, set the V.54 DLY
jumper in the modems located close to the DDS network to ON in order to
prevent multiple loopbacks.

Connecting the Line
The line connector is a five-screw terminal block, located on the ASM-10/8
rear panel as shown in Figure 2-2. The terminal block provides four screws
for connecting the transmit and receive telephone lines and one screw for
the ground connection. The transmit and receive pairs are polarity
insensitive.
