1 Scope
This European Telecommunication Standard (ETS) contains the signalling aspects of the Base Station
System for GSM. The set of signalling tests cover major areas of functionality on the air, Abis and
A-interfaces, but is not designed to be a complete set of all the possible scenarios.
The tests were designed from the set of core specifications that exist for the GSM network and any
changes that occur these specifications will be reflected in the test set documented within.
2 Normative references

normative references are cited at the appropriate places in the text and the publications are listed
hereafter. For dated references, subsequent amendments to or revisions of any of these publications
apply to this specification only when incorporated in it by the amendment or revision. For undated
