31.
Additional hardware is required.

When either of the 2 parties goes On-Hook (or presses Transfer key, Hold key, Answer key, Over key)
during Station-to-Station Calling [S-11], output of the billing information will be completed.
33.
Call Time specification:
• The base for Call Start Time and Call End Time is the time in the calling party-side node.
• In case there is time difference between each node, related time difference data, based on the UCT
(Universal Coordinated Time) standard, should be written in Network Data Memory (NDM) by using
the ATDF command.
• Because billing information gathering is performed in the called party-side node, the Call Start Time in
the originating node is determined in a way the deduction of time between calling and called party nodes
is added or subtracted to/from the called party-side time. (If there is no time difference data in any [both]
of the nodes, the Call Start Time is specified automatically by that in the called party-side node.)
• A counter, not the clock providing the current time, is used for Call End Time calculation. The
calculation method is as follows:
a.) Call Start Time (by using the clock) and the current counter value are registered to the Call Base
Table, soon after a line connection is established.
b.) Upon the call completion, the deduction between the counter value shown in a.) and that renewed
during the call exchange is calculated.
c.) The deduction is transformed to a time (hour, minute, second, milli-second) format.
d.) The transformed time is added to the Call Start Time registered in a.)-End.
•
The counter-based time is renewed in every 16.384 msec.
34.
The maximum number of calls available for concurrent storage in the system memory (active calls), is:
1-IMG/4-IMG system
28,000
IPX-U
47,000
35.
If an overflow occurs, calls are allowed to complete but are not recorded.
36.
To output the FCCS-related billing data, the external SMDR terminal should be compatible also with the
IMX text format patterns.
37.
When a station originates an outgoing trunk call using a trunk in the remote node (the station and the trunk
belong to an FCCS network), the billing information for the station to trunk connection is not recorded.
38.
Because the FCCS service achieves a completely fused link between multiple distant nodes, intrastation
connections and node-to-node connections are theoretically considered identical.
