You have a timing problem. The PM3 can only take clock from the =
loop, so the Adtran must be set up to provide clock to the span. =
The telco passes timing through the network.=20
Verify that the Adtran is set to Internal clocking under config - =
network (ni) - clock source
> Anybody have any ideas of what to try, I have tried INT and =
INT-INV
both on the Adtran for DTE TX CLK in the Port Config. On the =
network setup
These are timing options for the DTE side of the Adtran and have =
nothing to do with timing slips on the T-1.
>both sides are setup for B8ZS, ESF, the Adtran is set for =
internal clock,
because the PM3 will not supply clock. =20
Is this a full T-1? Verify the Adtran is set that way, no bit =
stuffing, 64k channels, 24 channels, continuous timeslots.
Verify the settings again. The PLL alarm indicates that the Adtran =
cannot sync up to the selected clock source.
Try changing the timing to loop and see what happens. =20
