TCAP TCO Configuration Bytes

The responding Transaction ID base cannot be configured if there are active TCAP transactions in progress. If the default base (0x 01 00 00 00) must be changed, it must be done in the initialization state.

Byte | Description | Value
--- | --- | ---
0x01 - 0x04 | Local Transaction ID Base for Network-initiated Transactions | The default base Transaction ID is 0x01 00 00 00. To avoid confusion, it is recommended that you use a different range of Dialog IDs for TC_USER-initiated dialogs.
