Two standards have recently emerged for signaling and control for Internet Telephony. One is ITU Recommendation H.323, and the other is the IETF Session Initiation Protocol (SIP). These two protocols represent very different approaches to the same problem: H.323 embraces the more traditional circuit-switched approach to signaling based on the ISDN Q.931 protocol and earlier H-series recommendat...

This paper focuses on the Call Control for the establishment and release of isochronous calls within the DAMS network (ESPRIT project #2146), a distributed ISDN PBX over an FDDI-II backbone optical ring that supports both isochronous and asynchronous traffic generated by ISDN terminals, LAN terminals, and Bandwidth On Demand (BOD) terminals. After a general overview of the DAMS network architec...

This document defines the framework for Centralized Conferencing. The framework allows participants using various call signaling protocols, such as SIP, H.323, Jabber, Q.931 or ISDN User Part (ISUP), to exchange media in a centralized unicast conference. The Centralized Conferencing Framework defines logical entities and naming conventions. The framework also outlines a set of conferencing prot...

In this paper, we present a new approach to the fabrication of integrated silicon-based piezoelectric diaphragm-type biosensors by using sodium potassium niobate-silver niobate (0.82KNN-0.18AN) composite lead-free thin film as the piezoelectric layer. The piezoelectric diaphragms were designed and fabricated by micro-machining technology and chemical solution deposition. The fabricated device w...
