2. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Setup
menu or click on the “Unlock FOCUS
Chassis” speed button. (password - focus1)
This puts the chassis — and the V2W/V2T
module — into a configurable state.
Figure 12–3. V2W / V2T Interface Module.
3. Insert the Two-Wire Voice (V2W/V2T)
Module into the FOCUS chassis.
For a remote telephone extension setup, make
sure you insert the V2T module into the
FOCUS chassis to which you are connecting
the PBX extension line and the V2W module
into the FOCUS chassis to which you are
connecting the telephone set.
For an intercom setup, you can insert either
V2W module into either one of the two
FOCUS chassis to which you are connecting
the “intercom” telephone sets.
Carefully insert the V2W/V2T 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 V2W/V2T module,
the red/green status LED is red. If the module
is functional, the status LED turns green
within 20 seconds. If the module is non-func-
tional, the status LED stays red, even after 20
seconds have elapsed.
4. Connect the proper wiring to the V2W/V2T
interface module.
The V2W/V2T interface module has both a
compression-type terminal block and two RJ-
9 connectors. As Figure 12-3 shows, one RJ-9
jack is for channel A, the other for channel B.
As Figure 12-3 also shows, the terminal block
has wiring connections for the two channels.
The MVI interface has one AMP “Champ” 50
as shown in Figure 12-4. It may be used to
interface up to three voice modules to termi-
nation points like jack fields, terminal blocks
or RJ-21X terminations. Please see Table 12-
1 for circuit, signal and pin assignments. It has
six jumpers on the inside top of the board.
These jumpers are used for setting the
signaling type for each of the six circuits. As
seen in Figure 12-5, 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.
If you are using telephone wires with RJ-9
connectors, simply plug the connector into the
RJ-9 jack for the channel you are using. As
Figure 12-3 shows, channel A is labeled “A”
and channel B is labeled “B.”
