The base station (100) has switching centres (101,MSC) and base stations connected through time division telecommunications links (103). A multiplexer/demultiplexer unit (104) multiplexes the links and demultiplexes data to be sent from the base station to the link. A time slot switch (200,201) selectively switches a desired transceiver unit (107,108) to the desired link. The switch has a time slot counter (204,214) which synchronises it with the time slots of the time division bus (103). A time slot selection register (205,212) stores specific time slot selection data. A comparator (206,215) compares the time slot selection data contained in the register with the state of the time slot counter so that the data in the time slot or at the transceiver is transmitted. A buffer (207,217) stores data on the link and feeds it into a transceiver or from the transceiver onto the desired time slot on the link. |
