73M1x66B Worldwide Design Guide

By: Jeff Sorensen

Abstract: Teridian's 73M1866B and 73M1966B provide highly integrated, globally compliant, silicon data access arrangement (DAA) for ultra-low-cost voiceband data and fax applications. The devices use a unique DAA function exclusively for foreign exchange office (FXO) of voice-over-IP (VoIP) and pulse-code modulation (PCM) systems. This article provides guidelines for designing and using the 73M1866B and 73M1966B for worldwide homologation. Topics include configurations for AC termination impedance, DC mask control, and ring-detector threshold.
