Below are some items that can be measured in the traffic control of ZTs.
Items Meanings
Outgoing Calls Measurement of the number of the PS in off-hook status.
This is counted to ZT that is grabbed when PS does Off Hook.
Completed  Outgoing  Calls Measurement of the number of the call that the called party answered. This 
includes the number of the call connecting to Announcement Trunk.
This is counted to ZT that PS is connected to.
Terminating Calls Measurement of the number of the incoming calls to PS.
This is counted to ZT that is grabbed when PS rings.
Completed Terminating Calls Measurement of the number of the incoming call answered by the PS.
This is counted to ZT that is grabbed when PS answers.
Line-Key Terminating Calls (
Note 1) Measurement of the number of the “Line-Key Terminating Calls” 
answered by the PS.
Paging Terminating Calls (
Note 2) Measurement of the number of the “Paging Terminating calls”.
Completed Paging Terminating Calls 
(
Note 2)Measurement of the number of the Paging Terminating calls answered by 
the PS.
No Answer of Ringing Calls Measurement of the count that the calls can not terminate to PS.
The cause of not terminating to PS is as follows:
- PS power off.
- PS is out of Zone.
- There is not idle Bch/Tch.
This is counted to Calling Area that PS do “Location Registration”. This 
is not count on a per PCN basis and ZT basis.
Re-Connected Channel Changeover Measurement of the number of the requested Hand-Over.
This is counted to ZT that PS does Hand-Over to.
Completed Re-Connected Channel 
ChangeoverMeasurement of the number of the completed Hand-Over.
This is counted to ZT that PS does Hand-Over to.
Position Assignment Request Count Measurement of the number of the “PS Location Registration”. PS do 
“Location Registration” in the following cases.
- PS Power ON.
- PS moves the Calling Area.
This is counted to ZT that PS is connected to for the “PS Location 
Registration”.
Bch All Busy Count for CS/ZT Measurement of the number of the Bch all busy on ZT basis.
In the case that Bch is made busy by command, even if other Bch became 
busy, this is not counted.
Abnormal Access Count Measurement of the number of the call that authentication fails.
This is counted to ZT that PS is connected to when authentication fails.

OfficeMeasurement of the number of the incoming calls to PS that is roaming to 
other PBX.
This is counted to the Calling PBX.
This is not counted on a per Calling Area basis and ZT basis (Kind=3,4).
Roaming Count for Visitor Office Measurement of the count that the PS of other PBX roams to self PBX. 
This is counted to ZT that PS is connected to when PS does Location 
Registration.
Abnormal Access for Visitor Office Measurement of the number of the call that authentication fails on the 
roaming PS. This is counted to ZT that PS is connected to when 
authentication fails.
T-ch can not Connect (
Note 3) Measurement of the count that Tch establishment fails by cause of radio 
part. This is counted to ZT that Tch establishment fails.
Release-out of Cell (
Note 3) Measurement of the number of the “squelch disconnect”.
