219 ZAUSL - User Activity Metering


Restrictions	Functions of the AMO	Error Messages and Advisories
Interrelationships	Parameter Description

Amongst other things, a PABX system offers a number of supplementary station features. User activity metering registers the active usage of each of these features.

This AMO evaluates the supplementary feature counters; no distinction is made between the communication services (voice, Fax, TTX, etc.) or traffic type. In addition, general traffic carried data is recorded and collated according to types of seizure.

After the counter states have been output, the text ’COUNTERS HAVE (NOT) BEEN CLEARED’ is displayed.

The AMO permits the counter states for supplementary station features and general traffic carried data to be output simultaneously, as well as offering the option of resetting the counters after output.
If any counter state equals or exceeds 16777215, the counter state is replaced by the text ’OVERFLOW’.

A metering run is automatically initialized and started when the system is started or restarted.

In the case of duplex systems, the counter lists for each of the two processors (standby or active processor or processor A or B) must be evaluated separately if the metering is still in progress after a routine changeover. This is because the counter values are not saved on hard disk.

The following is a complete list of the supplementary station features and the respective actions metered:

The following general traffic carried data is recorded:

•

N0001: Num. of internal seizures

This counter logs the number of times internal system users lift the handset of their telephones either to make internal/external calls or to activate features. Feature activation or interrogation via the Memory key is also included. All user telephones including attendant consoles are scanned regardless of whether the seizure was made offhook, handsfree, or via a feature key.

•

N0002: Num. of call processing events

This counter registers every software event in the central processor related to the processing (setup, release, transfer etc.) of calls in the system. An internal call between 2 analog telephones requires typically 9 events to be processed, a call between digital telephones typically 12 events; an external call from a digital telephone 18 events. The very large number of events processed for example in a large system in the course of a day can lead to overflow of this counter, (currently = 24 bit register) which will result in seemingly implausible values (eg. Dunton values attached).

•

N0003: Num. of call processing buffers allocated

Call processing buffers are pooled memory elements which are dynamically allocated each time call setup is attempted. This count gives an approximate BHCA value assuming ZAUSL has been run for an hour only.

•

N0004: Num. of external seizures incoming

This counter records the total number of calls signalled to the system node from an external source i.e.exchange calls, tie calls, transit seizures. A combination of this and "numer of internal seizures" gives an accurate BHCA value for the system concerned.

•

N0005: Num. of external seizures outgoing

This counter records the total number of calls leaving the sytem to an external destination (exchange, other node etc.).

•

N0006: Num. of calls answ. at ATND queue A / S1 til S12 (ANSDEV=COIC)

This counter registers all calls appearing on the trunk answer key i.e. "T" category on the attendant screen.

•

N0007: Num. of calls answered at ATND queue M (ANSDEV=O)

This counter registers all calls appearing on the operator key i.e. "O" category on the attendant screen.

•

N0008: Num. of seizures with trunk group key (ANSDEV=OUTG)

These are outgoing seizures dialled via the trunk group keys marked.

•
