Lucent Technologies introduced its next-generation SONET access multiplexer for enterprise installations in North America. The new Metropolis DMXplore Access Multiplexer is a single shelf, multi-service access device that enables 16 protected or unprotected DS-1s over an OC-3 interface. The unit, which is designed for fiber to the business and fiber to the curb applications, provides a pre-provisioned set of cross-connections (fixed mapping), which aids in quick deployments. The Metropolis DMXplore is supported by Lucent’s Navis Optical Management solution.

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.
