You mean say
0=Slave (Use PSTN clock)
1=Master(generate Internal clock)
So best option is 0 for all span if you connected on PSTN right ?

Subject: Re: [asterisk-users] DAHDI span timeing source
The timing source is the clock of the system. When a equipment is 0, the other should be 1. The correct is: 0=slave, 1=master. The default for private systems is “slave”.
