NEC NEAX2400 system manual System Configuration, Fusion System without FCH

CHAPTER 3 SYSTEM CONFIGURATION

Fusion systems can be divided into the following two types:

•Fusion system with FCH

•Fusion system without FCH

Note: Fusion Call Control Handler (FCH): PA-FCHA

This chapter explains the system configuration of each Fusion system.

1.Fusion System without FCH

A sample Fusion system configuration that does not use a DTI to carry D-channel is shown below. In this con- figuration, the Fusion link is established between nodes using Ethernet. The DTI card carries B-channels only in this example. Figure 3-1shows a Fusion System Configuration without FCH.

This figure shows a Fusion System Configuration without FCH.
