18.5. CDFD - Call data recording for PNE lines 
Feature:
Call data recording for PNE (Private Network Emulator) lines in the DTE service after
unscreened transfer
Function:
If a DTE transit connection to a PNE occurs after an unscreened transfer, only the
new
chargee is sent to call data recording instead of a charge data record.
Requirements: The waiting trunk must be an outgoing seized CO trunk circuit with
call data recording and the partner trunk which establishes the connection to the
PNE must
be a digital tie trunk circuit marked with the COT parameter CDFD.
IMPORTANT:
The CDFD function is already part of the PNE software in PNE software
status >= V3.0. Only set COT parameter CDFD on tie trunk circuits to the PNE and only
when the PNE software status is < V3.0. PNE SW V3.0 (at least) should be used in HiPath
4000 V1.0 and higher.
