Adaptive Clock Recovery |
摘要 |
<p>A method of recovering a clock signal for a TDM output from packets of TDM data which have been transmitted over a packet network, from a source having a source TDM clock to a destination having a destination TDM clock, comprises: providing at least some packets with a Remote Timestamp representing the state of the source TDM clock when the packet is created; providing said at least some packets with a Local Timestamp representing the state of the destination TDM clock when the packet is received; determining a Transit Time value representing the difference between said Local and Remote Timestamps; and controlling the clock frequency of the TDM output on the basis of said Transit Time as determined above. <IMAGE></p> |
