Technical Specifications

The E3-2/34Mbps, PDH Multiplexer is a third order skip multiplexer / demultiplexer unit, based on PDH (Plesiochronous Digital Hierarchy) technology. It multiplexes sixteen 2.048Mbps (hereafter referred to as 2Mbps) E1 tributaries intoa single 34.368Mbps (hereafter referred to as 34Mbps) E3 tributary. The multiplexer / demultiplexer also does the reverse processing i.e. demultiplexing a received 34Mbps stream into sixteen 2Mbps E1 tributaries.
