Figure 12–6. V2W/V2T Status Indicators.
The functionality of the LEDs is the same on both
modules. The red/green status LED is green if the
module is functional and red if the module is non-
functional. The green “busy” LED, when lit for
either channel, indicates that the module is trans-
mitting/receiving on that channel. The green
“ring” LED, when lit for either channel, indicates
that the module is transmitting/receiving a ring
signal on that channel.
12.4.2 Trunk Conditioning - T1/MV5
V2W, V2T, FXS & FXO modules have fixed
trunk conditioning (channels forced idle for 2.5
seconds when busy). Trunk conditioning is the
action of writing fixed signaling bit patterns to the
voice modules when a stream is in Red or Yellow
alarm.
12.5 Acceptance Test
As noted earlier, we recommend that you initially
install and test each set of V2W/V2T modules and
interfaces in a pair of “test” chassis (i.e., chassis
which are not part of an operating network). This
way, you can quickly perform the acceptance test
without interfering with a live network.
For both the remote telephone extension and
intercom tests you will need two chassis and two
touch tone analog telephones.
12.5.1 Remote Extension
Acceptance Test
For a remote extension, you need a V2W module
for the end of the circuit with the telephone and a
V2T module for the PBX end.
To test a two-wire voice remote telephone
extension using a V2T and a V2W, complete the
following steps for both the V2W and V2T:
1. Install the V2W and V2T modules and
interfaces in their respective test chassis.
If the modules and interfaces have not been
installed, do so now following the instructions
in the “Installation” section earlier in this
chapter.
When you first install either module in a live,
unlocked chassis, 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-functional, the status LED
stays red, even after 20 seconds have elapsed.
This is the first acceptance test.
2. Connect your PC to the FOCUS chassis.
Connect the RS232 cable from your PC to the
RS232 port on the front of the Maintenance
Module in the FOCUS chassis.
3. Start the FCS.
Bring up the FOCUS Configuration Software
(FCS), if it is not already running, by clicking
on the FCS program icon .
4. 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 V2T/V2W
module.
