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 inter-
nal registers which the user can access. These internal
registers are used to configure the device and obtain in-
formation from the T1 link. The device fully meets all of
the
latest
T1
specifications
T1.403–1989, AT&T TR 62411 (12–90), and CCITT
G.704 and G.706.
