Experimental 224 MB/S PCM terminals

Experimental 224 Mb/s terminal equipment for a toll-grade, long-haul PCM transmission system has been designed, constructed, and successfully operated. Transmission of television and frequency-multiplexed mastergroups of voice channels is emphasized. Fundamental design considerations are explored. Detailed designs and performance levels are briefly mentioned, but are covered in detail in companion articles.
