DESCRIPTION
The DS21Q41B combines four of the popular DS2141A T1 Controllers onto a single monolithic die. The
“B” designation denotes that some new features are available in the Quad version that were not available
in the single T1 device. The added features in the DS21Q41B are listed in Section 1. The DS21Q41B
offers a substantial space savings to applications that require more than one T1 framer on a card. The
Quad version is only slightly bigger than the single T1 device. All four framers in the DS21Q41B are
totally independent; they do not share a common framing synchronizer. Also, the transmit and receive
sides of each framer are totally independent. The dual two-frame elastic stores contained in each of the
four framers can be independently enabled and disabled as required. The DS21Q41B meets all of the
latest specifications including ANSI T1.403 (and the emerging T1.403-199X), ANSI T1.231-1993,
AT&T TR62411, AT&T TR54016, ITU G.704 and G.706.
