CHAPTER 6 POST INSTALLATION TEST
This chapter covers how to perform installation tests focusing on the Fusion Call Control Signal (denoted in the
remainder of this manual as FCCS) connections, after hardware installation and data assignment. This chapter
describes the following tests:
 How to Check Fusion Link by LEDs on an FCH Card
 Repair Procedure When LED Indicates Abnormality
 FCCS Network Connection Test
 FCCS Alternate Routing Test
 Fusion and Non-Fusion Connection Test
At the end of this chapter, the Fusion Link Test Sheet is attached. Make photo-copies of the sheet to record the
test results. 
In this chapter, explanations are given using the following network numbering as an example.
Figure 6-1   Fusion Network
Note:
The Individual Trunk Access feature is not available for Fusion Trunks. To seize a specific Fusion Trunk,
use the MBCT command to make busy trunks which are not being tested. This command leaves the Fusion
trunk to be tested in an idle state.
1. How to Check Fusion Link by LEDs on FCH Card
Before performing the Fusion link test, be sure to check the Fusion Link LEDs. Refer to Figure 6-2. When the
Fusion link is established, the LYR lamp lights green on the FCH (PA-FCHA) circuit card. However, if it re-
mains off, the layer 2 (Link Layer) is not established. If this is the case, follow the repair procedure listed here.

POST INSTALLATION TEST
Repair Procedure When LED Indicates Abnormality
1.1 How to check LYR LED
1. Confirm the LYR LED lights green on the front edge of the FCH (PA-FCHA) circuit card. (See “LED
Indication (A)” in Figure 6-2.) When the LED lights green, the fusion link is established.
2. Make sure that any alarm LED is not ON (red/yellow). (See LED Indication (B) in Figure 6-2.)
When all alarm LEDs are OFF, the DTI (PA-24DTR) card is in normal operation.
If any abnormal state is detected, please see the NEAX2400 IMX Circuit Card Manual.

2. Repair Procedure When LED Indicates Abnormality
If the LED indication appears abnormal, check the following items again:

POST INSTALLATION TEST
Repair Procedure When LED Indicates Abnormality
 FCH (PA-FCHA) switch setting
Make sure that the following keys are set properly:
 Dch TS designation (0ch - 23ch: SW11, SW12, SW13)
 Data Link Signal Logic (positive/negative: SW14-1)
 Fusion Data Link Speed (48/56/64 kbps: SW14-2, 3)
 LAPD Signal Link (user/network: SW14-4)
 24DTI (PA-24DTR) switch setting
Make sure that the keys are properly set on the card. See the NEAX2400 IMX Circuit Card Manual.
If the Fusion link is not established using this repair procedure, perform the Fusion Link Test.
2.2 How to Perform the Fusion Link Test
2.2.1 Fusion Link Test Mode Setting
To set the FCH card in Fusion Link Test Mode, set the Mode Switch to 9. Initialize the FCH card using
the MB key. When the Mode is 9, the Fusion Link Controller on the FCH card sends a test data pattern.
When the same pattern is received again the PM activates the LYR LED, flashing the LED at 60-INT,
which means the test result is OK.
Figure 6-3   Fusion Link Test Mode
Note:
Be sure to initialize the FCH (PA-FCHA) card, after changing the setting of the Mode Switch.
2.2.2 Loopback Point Designation
The DTI card can be set at one of the following loopback points:
1. Internal Loopback
