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.
