A novel monolithic QPSK-ready transmitter source based on prefixed phase switching by fast EAMs has been realized on InP using a flexible photonic integrating circuit technology.
We report a variable-gain and variable-bandwidth differential linear transimpedance amplifier (TIA-VGA) realised in a 0.7-µm indium phosphide (InP) double heterojunction bipolar transistor (DHBT) t
We transmit 16 WDM 20-Gbd QPSK channels over 12 spatial and polarization modes of 590- km few-mode fiber at a spectral-efficiency-distance product of 9440 km bit/s/Hz.
This paper present an overview of the 5ESS Switch Operator Services Position System Directory Inquiry (OSPS-DI) architecture and gives a brief account of the features and capabilities of the system
Customers constantly demand better product performance and support from their vendors. Vendors want to meet that challenge in the most effective, efficient way possible.
With the installation of the 5E4(1) generic at Oakbrook, Illinois in 1986, the 5ESS(R) Switch provided a proprietary realization of ISDN based on Alternate Mark Inversion (AMI) coding of the level
Using the ISDN capabilities of the 5ESS(R) Switch, AT&T's first international ISDN trails scheduled to start in Taiwan, Republic of China (ROC), in 1989.
With the introduction of the 5E6 software, the 5ESS(R) Switch will take another step toward the Information Age by offering advanced information services, as well as the capability to evolve with a
This presentation describes the Execution Environment System (EES), a general-purpose processor that is used to provide a pre-laboratory testing environment for the 5ESS(R) Switch generic program.
The ISDN standard interfaces open the door to a host of new capabilities and improved features for the business customer.
