[asterisk-users] TDMOE Timing

[Dave Fullerton]

Hello all,

I have two machines I'm connecting with TDMOE (dahdi dynamic spans) and 
I have a question about timing parameters. By my understanding one 
machine should be the source of the timing and the other a slave of that 
timing.

So on machine A I have the following in system.conf:
dynamic=eth,eth0/00:0C:29:55:89:7E,24,0

On machine B I have this is system.conf:
dynamic=eth,eth0/00:18:8B:C7:F6:94,24,1

So machine A is the source of timing and B is slave to it. If both of 
these machines also have a digium (TDM400P in one and a TE110P in the 
other) card in them is this configuration still correct or should I use 
0 for timing on both?

The reason I ask is if I boot both machines fresh and I execute 
dahdi_cfg on machine A first and then machine B I either get a kernel 
oops (with 2.6.27.11) or complete freeze (with 2.6.23.17) on machine B 
pretty much without fail. If I do machine B first and then A everything 
works fine. I'm using dahdi_linux 2.1.0.4 on both.

I know I can just use SIP or IAX or anything else to connect these two 
machines, but I'm using this as a learning experience to play with PRI 
setups.

Thanks

-Dave
