GENERAL DESCRIPTION

FEATURES

The DS3141, DS3142, DS3143, and DS3144

(DS314x) devices include all necessary circuitry to

frame and format up to four separate DS3 or E3

channels. Each framer in these devices is

independently configurable to support M23 DS3,

C-Bit Parity DS3, or G.751 E3. The framers interface

CꢀGenerate and Detect DS3/E3 Alarms

CꢀIntegrated HDLC Controller for Each Channel

CꢀIntegrated FEAC Controller for Each Channel

CꢀIntegrated Bit Error-Rate Tester (BERT) for Each

Channel

components without glue logic. Each DS3/E3 framer

has its own HDLC controller, FEAC controller, and

BERT, as well as full support for error detection and

generation, performance monitoring, and loopbacks.

CꢀLarge Performance-Monitoring Counters

CꢀLine, Diagnostic, and Payload Loopbacks
