■ Feature Flag (feat-flag) — 1 digit
The feature flag indicates whether a call received network answer
supervision, and if the call was interworked in the network. The call
duration starts at the point of receiving the network answer.
You can administer the feature flag (on the CDR System Parameters form)
to reflect whether an outgoing ISDN call was reported as interworked by
the network.
— A 0 in this field indicates a voice call without network answer
supervision, or NCA-TSC not established.
— A 1 in this field indicates a data call without network answer
supervision.
— A 2 in this field indicates a voice call with network answer
supervision, but interworked.
— A 3 in this field indicates a data call with network answer
supervision, but interworked.
— A 4 in this field indicates a voice call with network answer
supervision.
— A 5 in this field indicates a data call with network answer
supervision.
If the feature flag indicates that the call received network answer
supervision, then the time of answer is accurate, and the recorded duration
is also accurate. If a call does not receive network answer supervision, or
receives answer supervision but is interworked with non-ISDN trunks, the
time of answer is not necessarily accurate. Therefore the recorded duration
for these calls may also not be entirely accurate.
Calls are considered data calls if they use a conversion resource (such as a
modem) and/or originate or terminate on a data module.
■ Format Code — 2 digits
This field contains 2 values: 00 is no PPM; 03 denotes a PPM count in the
digits record.
■ FRL — 1 digit
FRLs, numbered 0–7, are associated with the AAR and ARS features and
define calling privileges. The information contained in this field is as
follows:
— If the call is an outgoing call and an authorization code is not used to
make the call, this field contains the originating telephone user’s
FRL.
