5. 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 .
This puts the chassis — and the V2T/V2W
module — into a configurable state.
6. Configure the DS0 channel assignments.
For instructions on setting the DS0 channel
assignments for the chassis’ channel modules,
please refer to the FCS online help facility
(Channel Assignments Map > Making Time
Slot Assignments > To set up the Channel
Assignments Map).
Assign one open DS0 channel, or time slot, on
XCVR-1 to channel A and another to channel
B. Make sure you assign the same DS0
channels, or time slots, to the same module
channels on both the V2W and the V2T.
7. Connect the PBX extension line/telephone
set.
At the FOCUS chassis with the V2T module,
connect the PBX extension line to the channel
A connection on the V2T’s interface module
on the rear of the chassis.
At the FOCUS chassis with the V2W module,
connect the telephone set to the channel A
connection on the V2T’s interface module on
the rear of the chassis.
In both cases, you can connect to either the
compression-type terminal block or the RJ-9
jack, as long as you use the connection for
channel A (see Figure 12-3).
8. Check for a dial tone.
Lift the receiver from the telephone connected
to the V2W module and listen for a dial tone.
Then hang up.
9. Call an outside telephone number.
Dial the telephone number for an outside line.
Make sure you can communicate in both
directions. Then hang up.
10. Have someone call you from an outside
line.
Have someone call you from an outside line.
Make sure you can communicate in both
directions. Then hang up.
Repeat Steps 7–10 using channel B.
12.5.2 Intercom Telephone
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 intercom setup using two
V2Ws, complete the following steps for both
modules:
1. Install the V2W modules and interfaces in
two 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..
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.
