The Integrated Services Digital Network (ISDN) has been designed to provide end-to-end digital connectivity.
This paper describes the implementation of Integrated Services Digital Network in AT&T's 5ESS(TM) Switch.
This talk presents the status of the standards activities, both at the international and national level, on the ISDN physical layer interfaces.
TO characterize the end-to-end performance of AT&T's ISDN BRI services, a system called ISDN-ASPEN was developed.
Late in 1986, AT&T began its introduction of ISDN with the ceremonial first call involving Illinois Bell and McDonald's Corporation.
With the cutover of the 5ESS (TM) Switch, Generic 4.2, on December 18, 1987, ISDN became a reality for AT&T, Illinois Bell Telephone Company (IBT) and McDonald's.
This paper will be a short (20-25 minute presentation), non-technical tutorial on what ISDN is and what it will mean to the telecommunications industry.
The Third Generation Partnership Project (3GPP) specified the IP Multimedia Subsystem (IMS) standard.
This memo describes an integrated hardware/software CAD environment for use by system engineers, architects, designers, and implementors.
We explain why maximum-likelihood sequence estimation (MLSE) receivers for direct-detection optical communication systems do not achieve the single-pulse performance of threshold receivers, in whic
