Preface
The QuadFALC
TM is an 4 channel E1/T1/J1 Framer And Line interface Component, it is designed to fulfill all
required interfacing between 4 analog E1/T1/J1 lines and the digital PCM system highway/H.100 bus.
The digital functions as well as the analog characteristics can be configured either via a flexible microprocessor
interface, SPI interface or via an SCI interface.
To enable a seamless transition from QuadFALC
TM v2.1 to v3.1 designs and applications
A software compatibility mode is provided. This mode allows software written for the QuadFALC
v2.1 to be
used with the QuadFALC
TM v3.1 without changes.
A fully hardware compatibility is provided. Only because of the integrated serial resistors in the transmit line
interface of the QuadFALC
TM Version 3.1 the external resistors must be changed against that of the Version
3.1.
