“test” chassis (i.e., chassis that are not part of an
operating network). This way, you can quickly
perform the acceptance tests without interfering
with a live network.
This section provides two sets of acceptance tests:
one for a PLD chain configured with internal
addressing and one for a PLD chain configured
with external addressing. All commands except
“connect” should be lower case. The password
will only appear as asterisks.
To conduct the tests for a PLD chain configured
with internal addressing, you will need the
following:
• Three Party Line Data (PLD) Modules
• Three PLD module interfaces, two with
jumpers installed on pins 2–3 and 7–8
(these are the two you attach to the
“remote” and “end” PLD modules)
• Three FOCUS chassis connected in a loop
configuration
• One assigned time slot (DS0) on the
FOCUS T1/E1 line for all three modules
•APC with the FOCUS Configuration
Software (FCS) installed
• One straight (DTE to DCE), RS232 cable
to connect the PC to the front of the
FOCUS chassis (for configuration) and the
PLD “head” module interface (for testing
functionality)
To test a PLD chain configured for internal
addressing, complete the following steps:
1. Designate the purpose for each PLD
module/FOCUS chassis.
Designate one FOCUS chassis and the PLD
module you are installing in it as the “head.”
Designate the second as the “remote”
module/chassis, and the third as the “end”
module/chassis.
2. Connect the PC to the RS-232 port on the
front of the “head” FOCUS chassis.
(FCS should already be installed and
running.)
3. 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 PLD module.
4. 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 into a configurable state,
allowing you to properly install the PLD
module and interface.
5. Install the “head” PLD module and
interface.
Install the “head” PLD module and interface,
using the instructions in the “Hardware
Installation and Connections” section earlier
in this chapter.
When you first install a Party Line Data
(PLD) 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 accep-
tance test.
6. Configure the “head” PLD module.
Configure the PLD “head” module, including
the channel map assignment. Remember that
all three PLD modules must use the same time
slot.
Repeat Steps 2–6 for the “remote” and “end”
PLD modules/chassis.
Use the pin assignments in Figure 19-3 to
install jumpers between pins 2–3 and 7–8 on
the “remote” and “end” interfaces.
7. Connect the PC to the “head” PLD module.
Connect the PC to the “head” PLD module’s
interface, using the RS-232 cable.
