DESCRIPTION
The DS2141A is a comprehensive, software-driven T1 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 T1 lines. The DS2141A 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 T1 specification changes. The controller contains a set of 62 8-bit internal registers which the user
can access. These internal registers are used to configure the device and obtain information from the T1
