[Asterisk-Users] TDM400P Sync source

Hi,

I am trying to track down the reason to my  problems with sending and reciving fax with my PRI and 2 TDM400P Cards:

PSTN <-> PRI (E100P) <-> * <-> TDM400P <-> Fax Machine

I have used Zapbarge to listen to the data stream, but I can't say if it really have some time slips - fax kinda noisy in itself.

Using the zttool i saw the Sync source for the TDM are "internally" - what does that mean? Are they using an "on-board" source, or using the PRI (which is configured to use the telco as sync source).

The zttool reports this for the E100P:  Sync Source:        Digium Wildcard E100P E1/PRA C
For the TDM400P cards it reports : Sync Source:        Internally clocked 


Is there a way to specify which source the TDM cards should use?
