1.0 INTRODUCTION
The DS21Q41B Quad T1 Framer is made up of five main parts: framer #0, framer #1, framer #2, framer
#3, and the control port which is shared by all four framers. See the Block Diagram in Figure 1-1. Each
of the four framers within the DS21Q41B maintain the same register structure that appeared in the
DS2141A. The two framer select inputs (FS0 and FS1) are used to determine which framer within the
DS21Q41B is being accessed. In this manner, software written for the DS2141A can also be used with
only slight modifications, in the DS21Q41B.
Several new features have been added to the framers in the DS21Q41B over the DS2141A. Below is short
list of the new features. More details can be found in Sections 2 through 12.
