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. Photocopy the sheet to record the test results.
Figure 6-1 illustrates the network numbering that is used in this chapter to explain the installation tests.

The Individual Trunk Access feature is not available for Fusion Trunks. To seize a specific Fusion Trunk,
Note:
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
indications. When the Fusion link is established, the LYR lamp lights green on the FCH (PA-FCHA) circuit
card. However, if it remains off, the layer 2 (Link Layer) is not established. If this is the case, follow the repair
procedure listed below.
