STM switching arrangement
View Patent ↗An STM telecommunications switch comprising a plurality of parallel data switching planes and a parallel control planes, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port and wherein the data is switched in octets.
1. An STM multiplex telecommunications switch, comprising: a plurality of mutually parallel data switching planes and a control plane parallel thereto, each data switching plane having an equal number of input ports and output ports, and a central switching unit to switch each input port to an output port, the data being switched in octets; and main rotator means for connecting each input port cyclically to a timeslot of the central switching unit.
2. The switch as claimed in claim 1 ; and further comprising a second rotator means to connect each timeslot of the central switching unit cyclically to each output port.
3. The switch as claimed in claim 1 , wherein the main rotator means comprises a single stage of rotators.
4. The switch as claimed in claim 1 , wherein the main rotator means comprises multi-stage rotators.
5. The switch as claimed in claim 2 , wherein each rotator means comprises a single stage of rotators.
6. The switch as claimed in claim 2 , wherein each rotator means comprises multi-stage rotators.
