    Glossary Aging time The aging time is the time after which a learned MAC address is discarded if a SCALANCE X-100 has not received frames with this sender address during this time. Autocrossover Technique with which a TP port is automatically switched over between MDI and MDI-X assignment to make a connection independent of the port assignment of the device being attached.
  • Page 70 Glossary Monomode See Single mode Multicast A frame with a multicast address is received by all nodes prepared to receive this address. Multimode In multimode transmission, the pulse is transferred using many modes (waves) that travel along curved paths or are reflected within the core. Attenuation is mainly caused by physical absorption and dispersion as well as by mechanical bending.
  • Page 71 Glossary Single mode In single mode transmission, (and monomode transmission) the pulse is transmitted by a straight mode (wave). Attenuation is mainly caused by physical absorption and dispersion as well as by mechanical bending. The amount of attenuation depends, among other things, on the wavelength of the input light.
