Hi There, We have very old asterisk 1.2 running in production and it has following setting in /etc/zaptel.conf. I have read on web about span and they told span= <span num> ,<timing source>,<line build out (LBO)>,<framing>,<coding>[,yellow] Just wondering why it has timing source 0 ? 0=master, 1=slave right ? Do you think i should change it to 1 ? #Sangoma A102 port 1 [slot:2 bus:7 span:1] <wanpipe1> span=1,0,0,esf,b8zs bchan=1-23 dchan=24 #Sangoma A102 port 2 [slot:2 bus:7 span:2] <wanpipe2> span=2,0,0,esf,b8zs bchan=25-47 dchan=48 -------------- next part -------------- An HTML attachment was scrubbed...

[asterisk-users] DAHDI span timeing source
Hi 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".

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 ?

Hi There,
We have very old asterisk 1.2 running in production and it has following setting
in /etc/zaptel.conf. I have read on web about span and they told span=
<span num> ,<timing source>,<line build out
(LBO)>,<framing>,<coding>[,yellow]
Just wondering why it has timing source 0 ? 0=master, 1=slave right ? Do you
think i should change it to 1 ?
#Sangoma A102 port 1 [slot:2 bus:7 span:1] <wanpipe1>
span=1,0,0,esf,b8zs
bchan=1-23
dchan=24
#Sangoma A102 port 2 [slot:2 bus:7 span:2] <wanpipe2>
span=2,0,0,esf,b8zs
bchan=25-47
dchan=48

Looking in system.conf.sample in dahdi-tools [1] Choose 1 to make the equipment at the far end of the E1/T1/BRI link the preferred source of the master clock. Choose 2 to make it the second choice for the master clock, if the first choice port fails (the far end dies, a cable breaks, or whatever). Choose 3 to make a port the third choice, and so on. If you have, say, 2 ports connected to the PSTN, mark those as 1 and 2. The number used for each port should be different. If you choose 0, the port will never be used as a source of timing. This is appropriate when you know the far end should always be a slave to you. If the port is connected to a channel bank, for example, you should always be its master. Likewise, BRI TE ports should always be configured as a slave. Any number of ports can be marked as 0.

Tell me in one word. We have 2 PRI line connected with sangoma card what option would be good for me? 0 or 1 ? -S> Date: Fri, 27 May 2011 16:11:03 -0500 > From: sruffell at digium.com > To: asterisk-users at lists.digium.com > Subject: Re: [asterisk-users] DAHDI span timeing source > > On Fri, May 27, 2011 at 08:57:15PM +0000, satish patel wrote: > > > > 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 ? > > Not really.

I guess you are wrong here correct one is 0=master 1=slave If you connect to PSTN the you should user span=1,1,0 Check out http://www.cadvision.com/blanchas/Asterisk/DahdiT1trunk.html -- Sent from my iPhone On May 27, 2011, at 4:27 PM, Rafael dos Santos Saraiva <rafaelsnsa at gmail.com > wrote:> Hi > > The timing source is the clock of the system.
