Hi, Thank you for your help. For the timer, the doc mentions that a DAHDI card must be used!!!! What to use for timer if there is no card? Or, the timer does not matter if no hardware is available? -- BR Abdelkader Mosbah > yes it is possible. > In dahdi/system.conf you configure a dynamic span like: > # To Ast 2 > dynamic=eth,eth0/<MAC_of_Ast2>,31,0 > dchan=16 > bchan=1-15,17-31 > in the second system (asuming that Ast1 will provide the timing) > # To Ast 1 > dynamic=eth,eth0/<MAC_of_Ast1>,31,1 > dchan=16 > bchan=1-15,17-31 > and you use the span just lik you would use a hardware span. > The example is for a typical PRI setup, but with dynamic spans you may > have 124 chans (or more) in a single dynamic device: > dynamic=eth,eth0/<MAC_of_the_remote>,124,0 > dchan=1 > bchan=2-124 -------------- next part -------------- An HTML attachment was scrubbed...
