[Asterisk-Users] timing/clock problem

[Alex G Robertson]

Hi all,


We have been fighting with telco for a entire week.
Today they came here with a LITE3000 to analyze what is going on.


When I configure zaptel with no external clock, E1 gets aligned/synchronized 
with bit rate in 2048000 bps, both me and telco.
span=4,0,0,ccs,hdb3,crc4

But when I configure span4 to get clock source from telco they become 
unsynchronized. TElco bit rate stays in 2048000 bps, but asterisk stays on 
2048443 pbs!!
span=4,1,0,ccs,hdb3,crc4

Telco1 (Intelig) send alarms and I do not sync to then.

I have another PRI circuit used for data connections from Telco2 and I used it 
for testing.
Telco2 (Telemar) do not send alarms and I sync to then.


Does anybody have some idea about what is happening?

Regards
