Traffic Administration


The OMN:EXCH-TR comprises the functions to be carried out in the exchange within the scope of traffic data recording. Traffic data recording is divided into the following :

1. Traffic Measurement

2. Traffic Data Monitoring

3. Traffic Structure Measurement

4. Traffic observation

5. Directory Number Observation


1. Traffic Measurement Measures events and status duration, e.g.,

-Number of successful seizures of CRs in an LTG

-Number of delays during the seizures of code receivers in an LTG

-Number of incoming seizures from subscriber without dial signal etc.

Task:Traffic measurement provides data for the planning and operation of the exchange and the network.


2 Traffic Data Monitoring

Periodically compares software meter status with predefined threshold value. If the threshold value is exceeded, messages and data will be displayed that may indicate the call-processing problems.

Task:Traffic overload may be prevented by traffic management measures.


3. Traffic Structure Measurement Collects the data of individual calls in the form of data records,

or records data concerning traffic flow.

Task:The purpose of traffic structure measurement is to supply information about the volume, distribution and success of switching operations.

Traffic structure measurement is divided into:-Trunk group traffic structure measurement

-Total traffic structure measurement

-Originating traffic structure measurement

Traffic Administration4. Traffic observation Records call-related data & utilisation of affected objects.

Task:The objective of traffic observation is to record and output values and data observed during the processing of statistically selected calls to analyse the following:

- system and network behaviour- system performance- grade of service - quality of service - traffic structure- subscriber or signalling behaviour

Traffic Administration 5. Directory Number Observation

Records call related data of subs. or PBX lines under obs. by ordinary calls or subs. controlled inputs,e.g.:

- Directory number - Local area code- Types of line

- Seizure time - Call duration

- Traffic type - Service - Subscriber feature

Task : The objective of directory number observation is to get a closer analysis of

subscriber behavior.

Procedure for Traffic measurement

-Call processing programs count the events and measure the status duration in the GP and CP, e.g. no. of seizures in GP.

-The call processing programs transfer the collected data to a buffer (traffic data saving).

-The traffic measurement recording programs read out the buffered data from the traffic data buffer and transmit it to the system disk

File name = TS.<object>.I<increment>

TS.<object>.<weekday><increment>

or edit and transmit the data to the assigned operating equipment

Procedure for Traffic measurement

-To specify the destination equipment as a disk or operating equipment.

REC <object> : UNIT = MDD/OMT, .... ;

-Traffic data are normally evaluated by means of post processing. The traffic measurement files may be copied onto magnetic tape/ magneto optical disk for this purpose

-The traffic measurement data may be edited and logged on the input device with GET TRAFILE.

-Furthermore, an overview of the traffic measurement files and traffic measurement orders may be displayed.

To create Groups of Traffic Objects

•Objects to be subject to Traffic Administration can be compiled in Traffic Object groups.

•These groups may be assigned any name.

•The group type is selected in accordance with the objects to be observed.

CR TR O GRP: GRP = <group name>,

GRPTYP = {DEST, PBX, TGRP, etc.}

To add traffic objects in a group so defined,

ENTR TRO PBX : GRP = ,

DN = , LAC = ; or

ENTR TRO DEST: GRP = ,

DOCODE = , [DLAC = ] ;

To create Groups of Traffic Objects

•Upto 50 groups may thus be formed. An Object Group for destination area may contain upto 512 objects. Similarly an Object Group for PBXs may contain upto 256 PBXs.

To display the created Object Groups,

DISP TRO GRP;

To display all the objects in a specific Object Group,

DISP TRO : GRP = group name;

Determining the Busy Hour

-The daily peak hour is the hour of a day when the highest traffic measured on TGRP/PBXs is recorded.

-ADPH Measurement is used to calculate the average values of the daily peak hours during a period of 14 days

-The EWSD determines the traffic load values in the busy hour by the "Average of Daily Peak Full Hour" method (ADPFH).

-The recorded data are output in daily files. Files are created for two weeks.

-The ADPFH measurement records following measured data, among other things:

- the beginning of the hour with the highest traffic intensity

- the traffic intensity (total incoming and outgoing)

- the sliding mean value of the traffic intensity

- the time during which all trunks are busy

- the number of cases when all trunks are busy

Average Daily Peak Hour Traffic Measurement (ADPHMEAS) jobs

-Up to 200 trunk groups (TGRP) and up to 600 PBXs can be included in the ADPFH measurement.

-New measurement objects can be included in the measurement at any time & measurement objects can be cancelled. For new measurement objects, measurement begins at 0:00 hours on the next measurement day.

-To enter measurement objects in the ADPFH job listENTR ADPHMEAS:

TGNO = <trunk group number>,

GRP = <traffic object group>,

DN = <PBX directory number>,

[LAC = <local area code>] ;

Traffic Data Monitoring

1. Traffic Monitoring for Trunk groups

-It is started by entering ENTER TRAMON.

-The measurement is activate either for all the trunk groups in an exchange or for up to 4 traffic object groups .

-The threshold values entered define the interval in which Load or ATBT lies.

-One to three threshold levels for each function can be entered.

-The O/P will be done to the disk file every 15 minute every time the job is activated, with a range indicator which shows in which interval the value is placed.

-A Display of the measured data for the last interval can be obtained with DISPTRAMON: ….., ACTREC =Y;

-Traffic monitoring can be can be cancelled with CAN TRAMON.


2. Traffic Monitoring of the CP

-There is a measuring of all processors of the CP (BAP,CAP).

-The CP load is defined as the sum of the processor leads of all active processors divided by the sum of the active processors.

-The output of the measured values will be done to disk file every 15 minuted every time the job is active with range in indicator that shows in which threshold range the value is placed.


3 Coinbox Traffic Monitoring

The feature “Coinbox Monitoring”can be used to detect public coinboxes that are out of service i.e. no chargeable call has been originated from there during the last monitoring period of 15 minutes.

First of all a traffic object group must be created. A maximum of 512 coinboxes can be the members of one group.

4 DLU Traffic Monitoring

The feature can monitor the behaviour of entire DLU concerning

No. of rejected call set ups because of lack of DLU-LTG time slot, lack of LTG-SN speech channels . The parameter BLKTHR (0…99999) defines the threshold for blocked calls per 15 min interval.

The duration of all speech channels busy or all time slots busy,the parameter ACHBTTHR (0…900) defines the threshold.

Traffic Structure Measurement

Unlike traffic measurement, traffic structure measurement is call-related, not object-related.

Traffic structure measurement may be related to the Trunk Group, Total Traffic, Originating Traffic, DLU or PA.

Traffic structure measurement is performed randomly. Thus, data is collected for every nth call only. The factor ‘n’ is specified as the parameter F, during order activation .

Once the ICTST buffer is full, its contents are transferred to the cyclic file IA.ICTST. The buffer data may also be transferred upon request using the command TRANS BUFFER.

MML commands for Traffic Structure Measurement

To activate traffic structure measurement

ENTR TRST: TGNO = <trunk group number> orGRP = <traffic object group>TRST = ALL/ INC/ ORIG DLU = < DLU number>PA = < PA name >V52IF = < V5.2 Interface Number >F = <factor>,BEG = begin date,TER = termination date,IV = hh1 - mm1 - hh2 - mm2,PER = MO/ TU/ ………….. / SU/ WO/ HO ;

( max. 8 trunk groups for direct input, max.3 object groups may be linked)

Related Commands: DISP TRST, CAN TRST

Directory Number Observation

Like in traffic observation call related data is recorded but for each call.

The collected values provide the basis of subscriber behaviour. Subsequently the required resources and the expected flow of traffic can be estimated.

The directory number observation is performed on analog subscribers, PBX or ISDN subscribers

Once the ICDNB buffer is full, its contents are transferred to the cyclic file IA.ICDNB. The buffer data may also be transferred upon request using the command TRANS BUFFER.
