HSCX for Siemens Primary Access Interface
The Siemens devices for the Primary Access Interface are the Advanced CMOS Frame
Aligner (ACFA) and the Primary Access Transceiver (PRACT). These devices can directly be
connected to the HSCX without any additional glue logic. In combination with the HSCX this
application is the most effective way to build a powerful and flexible Primary Access Interface,
especially supporting different combined B channel paths over long distances (LAN-WAN
Internetworking). The following block diagram illustrates how easy it is to integrate the HSCX
into a Primary Access application based on Siemens devices.
