Hi group,
Have you any idea for url which described about sonet/sdh framing in more
detail....i still a bit confuse about what is distinction between sonet and
sdh framing.
Once more, have anyone have idea about the distinction between Add Drop
Multiplexer, Terminal Multiplexer, Intermediate Regenerator (IR), Digital
Cross-connect (DXC). I found this term in Ericsson AXD 155-3.
anyway, sorry for the stupid question.
Just for trying learn about this in more detail. Any help will be
appreciated.
Thanks for your attention.
Regards
sipitung
