Description: The number of currently closed G-CDRs on the GGSN which have not been sent to the CG. The G-CDR shall be closed on encountering some trigger conditions. In the event that the G-CDR is closed and the PDP remains active, a new G-CDR will be opened for the PDP.

Trigger Condition: This counter is triggered when the CDR is closed. The closure might be due to different trigger conditions. a) Clearing of the CDR using CLI. b) Tigger conditions like vloume limit, time limit, sgsn change limit, container change limit set with configuration objects. c) CDR size reaches maximum.
