Question 25/XV - Characteristics of monitoring points on digital
transmission equipment and systems (New Question)

Considering

(1) that a new Recommendation on protected monitoring points on digital
transmission equipment has been produced during the study period 1985-
1988;

(2) some items in the new Recommendation require further study;

(3) that monitoring points are an additional means to a
Telecommunications Management Network (TMN) for temporarily monitoring
the transmitted signal for purposes of fault findings,

What revisions and amendments of Recommendation G.772 are necessary?

Points for study

1.Completion of Recommendation G.772.

2. Interfaces at the:

2.1 transmission path

2.2 monitor point.

3.Degree of protection from electrostatic discharge and inadvertent
application of voltage.

4. Types of measuring instrument to be connected to the monitoring
points.
5. Experience with monitoring points.

6. Accessibility of monitoring points - frequency of use.

7. Definition of monitoring point (see Recommendation M.60).

Notes

1. Close coordination with Study Group IV will be necessary in the study
of this Question.

2. Account should be taken of the study of Operations, Administration
and Maintenance interfaces carried out under Question 9/XV.
