INTERNATIONAL TELECOMMUNICATION UNION
ITU-T RECOMMENDATION SUMMARY
Rec. No. : E.502
Title : Traffic measurement requirements for digital telecommunication
exchanges
Study Group : II - Network Operation
Version : Revised
Date of adoption : 1992
Notes :
Recommendation E.502 applies to all digital telecommunications
exchanges operating in a switched telephone network and ISDN.
Traffic measurements on exchanges and surrounding network provide the
data base from which the dimensioning, planning, operation and
management of the network are carried out.
Information gathered from these measurements can be used for:
- identifying traffic patterns and distributions on a route
and destination basis;
- determining the amount of traffic in the exchange and the
network;
- monitoring the continuity of service and the grade of
service.
The above data and information are gathered with the purpose of
supporting the following fundamental activities:
a) dimensioning, planning and administration of the exchange
and surrounding network;
b) performance monitoring of the exchange and surrounding
network;
c) network management;
d) operation and maintenance of the exchange and surrounding
network;
e) tariff and marketing studies;
f) forecasting;
The information generated by the exchange (see Recommendation Q.544)
can be provided to the end user in either real-time or non real-time
(post processed). The activities being performed by the end user will
dictate the speed of this response: for example, operation and
maintenance will require real-time information while the forecasting
and planning information can be provided after the event in non
real-time.

form is available on ITUDOC (Winword: UPI=ITU-5265; ASCII: UPI=ITU-2488).
