ADC introduced a new “LoopStar” 800 next-generation SONET access system designed to help carriers deploy and manage TDM and Ethernet services to end-user customers from a single platform. The LoopStar 800 was developed under an original equipment manufacturer (OEM) agreement with Huawei Technologies. The platform uses an integrated universal back-plane architecture that supports multiple interchangeable network and tributary interface cards for DS1, DS3 and Ethernet service deliveryhttp://www.adc.com

From the Technology Graveyard
You just read about SONET. Here is what it replaced:
PDH (T1/E1/DS3) served from 1962. What ultimately replaced it?
PDH (T1/E1/DS3) time-division multiplexing that interleaved 24 (T1) or 30 (E1) 64 kbit/s voice channels into a frame, then stacked those into higher rates by bit-stuffing loosely synchronized streams. Its job passed to SONET — but the problem it solved, and the ideas it proved, live on in what replaced it. The standard rests here in the archive. One of 198 technologies here that opened a door and then held it for the next.
