73M1866B/73M1966B MicroDAA™ with PCM Highway Simplifying System Integration™ DATA SHEET DS_1x66B_001 April 2010 DESCRIPTION The 73M1866B and 73M1966B use the Teridian patented Data Access Arrangement function (MicroDAA®) designed exclusively for ForeignExchange-Office (FXO) in Voice-over-IP (VoIP) applications. These devices provide much of the circuitry required to connect PCM formatted voice channels to a PSTN via a two-wire twisted pair interface. The package options provide the necessary functional programmability and protection required for easy worldwide homologation. The family of devices consists of the 73M1866B and the 73M1966B. The 73M1866B MicroDAA is the world’s first single-package silicon Data Access Arrangement (DAA).
