The right thing to do is to sync to the PSTN. The E1s connected to the PSTN should be listed as the lowest numbered clock sources, starting from 1. Places you never want to sync to should be set to zero.
Your mail was very interesting, but to be honest I don't think I understood a single word of what you said :)
Then I think you need to just blindly follow a known good example.
This is my zaptel.conf configuration: loadzone = au defaultzone=au
#TE110P span=1,0,0,ccs,hdb3,crc4
This is wrong. You have only one E1. I assume it is connected to the PSTN, and you are not locking your local clock to the PSTN clock. You will get frame slips. If that make no sense, the bottom line is "this is bad". :-)
bchan=1-10 dchan=16 #bchan=17-31
#TDM400 fxsls=32-35
Do you mean that I should change the span=1,0,0,ccs,hdb3,crc4
into span=1,1,0,ccs,hdb3,crc4
The second parameter now says "treat this E1 as the first priority as the clock source". Your box should lock itself to the PSTN's clock. If that makes no sense, the bottom line is "this is good". :-)
I only have one E1 connected (on TE110P card) and a TDM440 (4 FXO ports)
