inside top of the board. These jumpers are
used for setting the signaling type for each of
the six circuits. As seen in Figure 13-3, if the
jumper is in the top position, that sets the
circuit for Type I signaling and in the bottom
position sets the circuit for Type IV/V
signaling.
5. Connect the V4W interface module to
the FOCUS chassis.
After connecting all wires, attach the V4W
interface module to the rear of the FOCUS
chassis so that it connects to the V4W module.
13.3.2 Software Settings
Once you have completed the hardware installa-
tion and connections, use the FCS to configure the
V4W module. You configure the module’s settings
on a per-channel basis. You can set the
transmit/receive gain offset, the transmit/receive
gain base, and the enable/disable signaling option.
The default parameter settings are shown in
Figure 13-5.
For instructions on configuring the V4W module,
please refer to the FCS online help facility

The Four-Wire Voice (V4W)
Module’s technical specifications are
shown in Table 13-1.
Figure 13–4. V4W Status Indicators.
13.4.1 Status Indicators
This module has five status indicators, as shown
in Figure 13-4. The red/green status LED is green
if the module is functional and red if the module is
non-functional. The green “M” LED, when lit for
either channel, indicates that the module is trans-
mitting signaling information on that channel. The
green “E” LED, when lit for either channel,
indicates that the module is receiving signaling
information on that channel.
