2.9.2 High-Speed Interface
A High-Speed Interface (HSI) Controller is used to connect certain high speed terminal
devices to the AW.
The high-speed interface card is equipped in the AW as follows:
• PCI slots (Netra 240) – PCI slot 2 is equipped with a High Speed Interface (HSI)
card that provides 4 ports for data link connections.
• PCI slots (Netra t 1120 and Netra 20) – PCI slot 3 is equipped with a High Speed
Interface (HSI) card that provides 4 ports for data link connections.
Figure 2-19, 2-20 and 2-21 provide illustrations of the HSI Controller High-Speed
Interface and its connection to the AW. Table 2-6 lists terminal devices that can be
interfaced using this controller.
