  • Patent number: 9847846
    Abstract: The audio outputs 29 of each of a plurality of telecommunications terminals in a packet switched system are synchronized by having each terminal transmit a stream of packets whose rate, and therefore duration is determined according to a clock generator 25, and is thus indicative of the rate at which the terminal is generating its audio output. The signals from each terminal are transmitted to a common server. For each terminal, the server uses a master dock to compare the duration of the packet stream with an expected duration, and calculates an offset value which is returned to the respective terminal. Each terminal stores the offset value it receives (20) and uses it to adjust the output of its clock generator 25 so that its operations can be synchronized to the server. This allows all the terminals' digital-to-analog conversion processes to be synchronized such that all their analog outputs are coordinated, allowing co-located acoustic outputs to be synchronous.

  • Patent number: 9609125
    Abstract: A telecommunications server (2) controlling a plurality of telecommunications terminals (4) connected to a packet switched telecommunications system (40, 41), responds to call events (20) by transmitting an alert (251, 252) to each of the terminals. If the server is not capable of processing all the required event alerts in parallel, it processes the event alerts to the terminals in a predetermined sequence, according to stored prioritization rules (60). The priority accorded to an individual terminal may be set according to the alert mode (visual-only, or audible) currently set for that terminal (or the user currently using the terminal) for that call type or calling party.

    Abstract: The audio outputs 29 of each of a plurality of telecommunications terminals in a packet switched system are synchronised by having each terminal transmit a stream of packets whose rate, and therefore duration is determined according to a clock generator 25, and is thus indicative of the rate at which the terminal is generating its audio output. The signals from each terminal are transmitted to a common server. For each terminal, the server uses a master dock to compare the duration of the packet stream with an expected duration, and calculates an offset value which is returned to the respective terminal. Each terminal stores the offset value it receives (20) and uses it to adjust the output of its clock generator 25 so that its operations can be synchronised to the server. This allows all the terminals' digital-to-analogue conversion processes to be synchronised such that all their analogue outputs are co-ordinated, allowing co-located acoustic outputs to be synchronous.
