Application

A transmission system must be speciﬁed for its overall error performance, measured

over a period of time. Conformance to these speciﬁcations ensures that an installed

system will meet the requirements of an Integrated Digital Network (IDN).

After troubleshooting, or during installation or commissioning, it is necessary to

check that the transmission link meets this error performance.

This can be performed in two ways:

• End To End - Error performance measurements are made on an end-to-end basis

testing the Go and Return paths separately but simultaneously. The measurements

are often performed unattended and the results and other events, alarms for

example, logged on a printer or disc and timed by a real time clock facility.

Two HP 37717C's are required for this measurement, one at each end of the link.
