This first part of ETS 300 287 defines the Transaction Capabilities1) (TC) signalling protocol to be used in and between networks@ for non-circuit related services which use Signalling System No.7 for inter-network dialogues. Only those parts of TC which are used by the above services need to be provided. The support of TC by terminal equipment is outside the scope of this ETS. This ETS covers only TC for use over a network layer consisting of Signalling System No.7 Message Transfer Part (MTP) plus Signalling Connection Control Part (SCCP). NOTE: This is valid for both 1988 and 1993 versions. 1) For historical reasons@ the terms Transaction Capabilities (TC) and Transaction Capabilities Application Part (TCAP) are used interchangeably.
