Telecommunications Fast Facts, Last Updated:09/09/2010 The DS0's are the basic granularity at which switching takes
place in a telephone exchange. DS0's are also known
as timeslots because
they are multiplexed together in a time-division fashion. Multiple
DS0's are multiplexed together on higher capacity circuits, such
that 24 DS0's make a DS1 signal, which when carried on copper is
the well-known, T-carrier system, T1 (the European equivalent is an
E1, containing 32
64 kbit/s channels). In modern networks, this multiplexing is moved
as close to the end user as possible, usually into cabinets at the
roadside in residential areas, or into large business premises. |
