Description / Abstract:

This Recommendation specifies the requirements and test procedures for termination modules with contacts for test ports or SPDs (see clause 3.2.15) used for symmetric pair conductors subjected to overvoltages and overcurrents.

Note, other Recommendations exist, such as [ITU-T K.12] and [ITU-T K.28], specifying characteristics for surge protective components (SPCs).

An example of where termination modules included in the scope of this Recommendation may be used is given in Figure 1. The following types of terminating modules covered by this Recommendation are:

• a termination module with terminals but without the facility for an SPD;

• a termination module with terminals and the facility for an SPD;

• an integral termination module/SPD. The termination module and SPD are not meant to be separated.

This Recommendation does not cover the requirements of termination modules used in equipment. These are covered by the relevant equipment Recommendations, i.e., [b-ITU-T K.20], [b-ITU-T K.21] or [b-ITU-T K.45]. It does not cover either the requirements of insulation displacement connectors or termination modules without contacts. These are covered by [ITU-T K.55].

Refer to Appendix I for information on when and how to test termination modules.

Basic Recommendation [ITU-T K.44] (test methods and test circuits) is an integral part of this Recommendation. This Recommendation should be read in conjunction with [ITU-T K.11], [ITU-T K.39], [ITU-T K.46], [ITU-T K.47] and [IEC 61643-21].
