Unless signaling is either active (as when used for
telephone channels off hook) or disabled, an
audible “click” is present once each min. when the
module is re-programmed.
13.3 Installation
As with other FOCUS modules, we recommend
that you initially install and test the V4W module
and interface in a “test” chassis (i.e., one that is
not part of an operating network). This way, you
can quickly perform the acceptance test without
interfering with a live network. Whether you are
installing the module in a test chassis or a chassis
that is on line in a network, use the installation
procedure described here.
The Four-Wire Voice (V4W) Module occupies
one chassis slot. The module’s two channels
require two (2) time slots on the T1/E1 line.
Before installing the module and its interface,
make sure that:
• The FOCUS chassis is set up, energized,
and operational, with all necessary
common equipment (see Chapter 3)
• The FOCUS Configuration Software (FCS)
has been installed on your PC (see Chapter
3)
• Acceptance tests for the FOCUS chassis
and all previously installed equipment have
been done to rule out invalid test results for
this module
• FCS is up and running (see Chapter 3)
13.3.1 Hardware Installation and
Connections
To install the V4W module and interface,
complete the following steps.
1. Bring the FOCUS chassis “on line”.
Click on the “Online” speed button
.
This uploads to the FCS the current status,
settings, operating statistics, etc., for the
FOCUS chassis — and the V4W module.
2. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Setup
menu or click the “Unlock FOCUS Chassis”
speed button. Enter the password (factory
default is focus1). This puts the chassis — and
the V4W module — into a configurable state.
3. Insert the Four-Wire Voice (V4W) Module
into the FOCUS chassis.
Carefully insert the V4W Module into the top
and bottom grooves of any open slot on the
FOCUS chassis. Slide it all the way in until it
is well seated in the slot. Lock it into place
using the black inject/eject lever on the front
of the module.
When you first insert the V4W module, the
red/green status LED is red. If the module is
functional, the status LED turns green within
Figure 13–1.
