Opisano opracowaną w Instytucie Łączności metodykę i procedury badań, umożliwiające testowanie poprawności współpracy terminali abonenckich wyposażonych w odbiorniki kodu FSK z centralami sieci użytku publicznego podczas realizacji usług CLIP CW, MWI i SMS. Prezentowaną metodykę opracowano na podstawie dokumentów ETSL Procedury badań obejmują usługi oferowane w krajowej sieci użytku publicznego.

In this article, the methodology and test procedures developed by the National Institute of Telecommunications that enable it for the correctness of the joint action of the subscriber's terminals equipped with FSK code receivers with the exchanges of the public networks to be tested while providing CLIP CW, MWI and SMS services are described. The methodology presented here is based on the ETSI standards. The test procedures cover the services offered in the national public network.

Implementation of new services in the network requires appropriate methods and tools for checking correctness of interworking between terminals and exchanges. In this article the methodology and test procedures prepared for testing terminals handling FSK protocol transmitted over the local loop for display and related services was described. Methodology presented here is based on ETSI standards. Test procedures were developed for services offered in Polish network. Tests cover all levels of FSK protocol. For two lower layers, separate procedures for ^on-hook" and "off-hook" loop states were prepared. The procedure for "on-hook" state contains tests related to data transmission "associated" and "not associated with ringing". These procedures cover normal cases with parameter values and sequence elements complying with standards and exceptional procedures with the extreme values of the parameters and with modified elements of the sequences.
