2.1 System Configuration
A sample Fusion system configuration that uses a DTI to carry D-channel is shown below. In this configu-
ration, the Fusion link is established between nodes via the T1 link.

PCI Bus
TSW (Time Division Switch): PH-SW 10
HUB: PA-M96
MUX: PH-PC36
LANI (LAN Interface): PZ-PC19
FCH (Fusion Call Control Handler): PA-FCHA
DTI (Digital Trunk Interface): PA-24DTR
2.2 Redundancy of Fusion Link
The FCH (PA-FCHA) card handles a Fusion link, occupying one time slot of a frame by D/I function located
on the DTI card. In terms of redundancy, the Fusion system (with FCH) can have one of the following config-
urations.
• Redundant Configuration (LANI, HUB, FCH, and DTI)
• Redundant Configuration (HUB, FCH, and DTI)
• Redundant Configuration (FCH and DTI)
• Non-Redundant Configuration
