2 Extension Container The extension container is a data type definition that facilitates the transfer of operator-specific or vendor-specific information in an operation. Extension containers are included in most CAP Burst ::= SEQUENCE { numberOfBursts burstInterval numberOfTonesInBurst toneDuration toneInterval ... 1 definition of CAMEL phase 4 flexible tone. 2, would be developed. 2 at present. Introduction to Intelligent Networks 27 operation arguments. The operator may decide to place designated information elements in the extension containers.

The IN service responds by sending the continue operation, which instructs the SSF to continue call establishment. In the pre-arranged end example, the SCF does not explicitly close the IN dialogue. However, since the SCF did not arm any of the DPs in the BCSM, there will not be any further communication between SSF and SCF through this IN dialogue. The SSF and SCF therefore decide to close the IN dialogue. In the basic end example, the SCF instructs the SSF to continue call establishment and at the same time instructs the SSF to close the IN dialogue.

The TC messages are encapsulated in SCCP messages and then transported to the destination entity by the SCCP and MTP. 771 [140]. The following TC messages are used for the dialogue management. • TC Begin – this TC message is used to initiate a TC dialogue; TC Begin may contain operations like initial DP, initiate call attempt or assist request instruction. • TC Continue – this TC message is used to continue or to terminate a TC dialogue (with prearranged end) and to transfer one or more CAP operations, CAP error or CAP result.
