Subscription Option - Charging information
This facility allows the network to send to the DTE information about the
charge for that call and/or other information which makes it possible for the
user to calculate the charge.
This information is sent in the clear request or clear accepted packets.
If the DTE is the DTE to be charged, the DTE can request the charging information
facility on a per call basis by means of an appropriate facility request in
a call request or call accepted packet.
If a DTE subscribes to the charging information for a contractual period,
the facility is in effect, whenever the DTE is the DTE to be charged, without
sending this facility.
UK(a) - uses non-standard facility field codeing.
UK(b) - not supported.

not possible because no mechanism exists for setting the time of day clock in

TNDTED Q162(was q46 ) clear charging information (YES/NO)
|TNDTED Q162| q46 | clear charging information..........#default NO

This question determines whether a DTE should receive CCITT charging information
facilities. If the DTE is to receive these facilities, the network will include
call duration and segment count information in the clear indication or clear
confirmation packets that are sent to the DTE. The information, in binary coded
digits (BCD), will be transmitted to the DTE only when the DTE is charged for
new for release 4
We need to test out all combinations of UKa charging and CCITT charging.
