The EMU-830 is compatible with HDSL, G.SHDLS cards, desktop units, doublers (regenerators), and exchange
office management shelves in the WorldDSL product line. Universal Termination Units (UTUs) can be configured as
LTUs or NTUs. WD92xGx can be configured as STU-Cs or STU-Rs. Typically the LTU/STU-C DSL cards are
installed in the management shelf and the NTU/STU-R DSL cards are deployed at the remote site. You can,
however, use either an LTU/STU-C or NTU/STU-R DSL card in a shelf as the EMU-830 allows terminal access to
both types of DSL cards when installed in a shelf. Alarm management, however, is only performed on LTU/STU-C
cards and their attached circuit elements.
