Configure voice router as a ISDN clock master

[cukouncukoun]

Is it possible to configure router as a clock master for ISDN PRI line??

I know that this is possible for ISDN BRI interface - layer1-emulate network command on that interface but this command is missing on PRI serial interface.

Any suggestions?

Hi,

The command "isdn protocol-emulate network" command under the D-channel interface.(Int serial 0/0/0:15 for E1-PRI or int serial 0/0/0:23 for T1-PRI)

should work.

Thank you,

but I already tried this command and it is not working :-(

Guys on the other side of E1 line (some another PBX) did not see any clocks from my side and I still saw at this E1 controller that "clock source is from line".

I thing that this commnad is only for ISDN L3 master/slave configuration but not for L1 layer.

You can try the following:

network-clock-participate slot 1

controller T1 1/0/0

clock source internal

Ya i agree that the command is for Layer 3.

You can try the above two commands suggested by phooghen. I think it should solve your problem.
