i?ve dealed around with two E400P Cards the last 3 Days and I cant
figure out why this problem exists.
Here the description:
I have two E400P Quad E1 Cards. One is in NT Mode and the other is in
TE(CPE) Mode.
When I connect both cards via E1-Cross Cabel the cards wont sync. I see
in zttool Red Alarm and SyncSource:Internally Clocked.
I see Bipolar Voilations Counting up.
Now comes the tricky part.
I have a third Card. A Rhino R4T1 in E1 Mode(TE). When i plugg my
crosscable from E400P to Rhina. Pling Sync is perfect.
zttool says : no alarms, SyncSource : Tormenta PCI...... Everything is fine.
What the hell (sorry) is the problem?!? Dont know why both E400P Cards
wont sync. But they sync if i plug it into a rhino port.?!?!
Anybody has some idea?!?!
Here is my zaptel.conf of the E400P in NT Mode:
span=1,0,4,ccs,hdb3,crc4
span=2,0,4,ccs,hdb3,crc4
span=3,0,4,ccs,hdb3,crc4
span=4,0,4,ccs,hdb3,crc4

Just my guess:
None of the spans (ports) is configured to provide clock to the other
side.
If you want to cross-connect port 1 and port 2, you should use something
like:
span=1,1,4,ccs,hdb3,crc4
span=2,0,4,ccs,hdb3,crc4
(And run ztcfg after that)
