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 through 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 by 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 that the user can access. These internal registers are used to configure the device and obtain information from the T1 link. The device fully meets all of the latest T1 specifications including ANSI T1.403-1989, AT&T TR 62411 (12-90), and CCITT G.704 and G.706.
