SDH (E1, E3, STM-1 do STM-64)
SDH (Synchronous Digital Hierarchy) is a leased TDM point to point line. SAT-TRAKT may realise this service through its network of SDH multiplex-ers. Complete transparency of service is guaranteed.
DWDM (STM-16, STM-64)
DWDM (Dense Wavelength Division Multiplexing) is a leased TDM point to point line. SAT-TRAKT may realise this service through its network of DWDM multiplex-ers. Complete transparency of service is guaranteed.
