1. Set the DS0 Channel Assignment Map.
(Refer to the FCS online help facility:
Channel Assignments Map > Making Time
Slot Assignments > To set up the Channel
Assignments Map for complete instructions.)
Note that some alarm LEDs may be on at this
point.
Repeat for all chassis in the system.
When the assignment map for the last chassis
is completed, all LEDs should be green.
2. Test all channels for proper operation.
3. Reset target buffers and error counts in all
chassis.
4.4.4 Maintenance Module Testing
When you first energize the Maintenance 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-functional, the
status LED stays red, even after 20 seconds have
elapsed. This is the first acceptance test.
To test the signaling push-button (Steps 10 and 11
below), you will need at least two chassis. You can
test as many additional chassis as you want. Make
sure that both (all) chassis have the version 3.x
Maintenance Module.
You must also enable the party line order wire
(PLOW) for both chassis, providing this option is
included (see “Channel Assignments Map >
Making Time Slot Assignments > To set up the
Channel Assignments Map in the FCS online help
facility).
To test the Maintenance Module’s functionality,
complete the following steps:
(For complete instructions on specific FCS proce-
dures, please refer to the FCS online help facility.)
1. Set up the chassis and other modules.
Set up the test chassis and all other channel
modules per your application.
2. Install the Maintenance Module.
Insert the Maintenance Module into the
chassis according to the instructions in the
“Installation” section earlier in this chapter.
3. Energize the chassis.
Energize the FOCUS chassis by applying
power.
When you first energize the chassis, and thus
the Maintenance 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-functional, the status LED
stays red, even after 20 seconds have elapsed.
This is the first acceptance test.
4. Connect the RS-232 cable from the PC.
Connect the RS-232 9-pin extension cable
(male–female) from the PC to the RS-232
interface on the front of the module. A
standard, straight through cable is required
(i.e., not a null modem).
5. Start the FCS.
Bring up the FOCUS Configuration Software
(FCS), if it is not already running, by clicking
on the FCS program icon .
6. 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 Maintenance
Module.
Observe that all common and channel module
status LEDs are green.
7. 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 channel
modules — into a configurable state. Note:
the default password is “focus1”.
