DESCRIPTION
The DS2143 is a comprehensive, software–driven E1
framer. It is meant to act as a slave or coprocessor to a
microcontroller or microprocessor. Quick access via
the parallel control port allows a single micro to handle
many E1 lines. The DS2143 is very flexible and can be
configured into numerous orientations via software.
The software orientation of the device allows the user to
modify their design to conform to future E1 specification
changes. The controller contains a set of 69 eight–bit
internal registers which the user can access. These
internal registers are used to configure the device and
obtain information from the E1 link. The device fully
meets al l of the latest E1 specifications including CCITT
G.704, G.706, and G.732.
