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.
