Abstract

An Ethernet Local Area Network uses a star topology connecting user stations to a Communications Switching Module (CSM) with 10Base-T or 100 Base-TX UTP cable. Each user station typically has a digital telephone and a data communication device, such as a PC communicating with the CSM through a common UTE adapter. Delay-sensitive digital voice signals and non-delay sensitive user data are transported in master Ethernet packets of fixed length transmitted at a fixed rate. Segmentation and re-assembly of data is performed in the UTE adapters and in the CSM.
