[Asterisk-Users] possible solution to PRI T100P dropped call issue

[John Brown (CV)]

To recap:

T100P card wouldn't sync with the telco using line side
clocking ( span=1,1,0.........) 

Had to use  internal clocking (span=1,0,0.......)

zttool  showed Tx/Rx Levels as  0/ 1


For the grins of it I replaced the T100P card with
another newer card from inventory.

This newer card has the same rev on the ASIC / FPGA
but doesn't have any of the various jumper headers
installed on the board.

Set clocking to line side
sync=1,1,0......

Poof, card comes up, span comes up. 

zttool  now shows  Tx/Rx Levels as  0/ 0

No other changes have been made to the various
configs on the system.


It seems in the end that this was some strange hardware
failure on the T100P card.
