<P> While circuit switching is commonly used for connecting voice circuits, the concept of a dedicated path persisting between two communicating parties or nodes can be extended to signal content other than voice . The advantage of using circuit switching is that it provides for continuous transfer without the overhead associated with packets, making maximal use of available bandwidth for that communication . One disadvantage is that it can be relatively inefficient, because unused capacity guaranteed to a connection cannot be used by other connections on the same network . </P> <Table> <Tr> <Th> Multiplexing </Th> </Tr> <Tr> <Td> </Td> </Tr> <Tr> <Th> Analog modulation </Th> </Tr> <Tr> <Td> <Ul> <Li> AM </Li> <Li> FM </Li> <Li> PM </Li> <Li> QAM </Li> <Li> SM </Li> <Li> SSB </Li> </Ul> </Td> </Tr> <Tr> <Th> Circuit mode (constant bandwidth) </Th> </Tr> <Tr> <Td> <Ul> <Li> TDM </Li> <Li> FDM / WDM </Li> <Li> SDMA </Li> <Li> Polarization </Li> <Li> Spatial </Li> <Li> OAM </Li> </Ul> </Td> </Tr> <Tr> <Th> Statistical multiplexing (variable bandwidth) </Th> </Tr> <Tr> <Td> <Ul> <Li> Packet switching </Li> <Li> Dynamic TDMA </Li> <Li> FHSS </Li> <Li> DSSS </Li> <Li> OFDMA </Li> <Li> SC - FDM </Li> <Li> MC - SS </Li> </Ul> </Td> </Tr> <Tr> <Th> Related topics </Th> </Tr> <Tr> <Td> <Ul> <Li> Channel access methods </Li> <Li> Media access control </Li> </Ul> </Td> </Tr> <Tr> <Td> <Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> </Td> </Tr> </Table> <Tr> <Th> Multiplexing </Th> </Tr> <Tr> <Th> Analog modulation </Th> </Tr>
