| 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. |
