| 1. A method for recording call failure information in a node in a data transmission system, the method comprising:
generating, in the data transmission system, a first failure log in response to a failure event, said first failure log including
a failure type and a first timestamp;
placing said first failure log in a queue maintained in the node;
formulating an identifier for said first failure log by inputting at least one field from said failure log into a formulation
function, wherein said at least one field is selected based on said failure type; and
when no existing record in a log record storage in the node includes said formulated identifier, creating a log record for
said first failure log and storing said log record in said log record storage, said log record including said formulated identifier.
