VC Tester Dc User Data

1.3.6.1.4.1.562.2.4.1.5130.3.10.1.8

This attribute contains the user data, if present. userData is a 0 to 16 length string which is appended to the call request packet that is presented to the called (destination) DTE. User data can be a 0 to 128 byte string for fast select calls; otherwise it is 0 to 16 byte string. Fast select calls are indicated as such using the X.25 ITU-T facility for 'Reverse Charging'. The length of the user data attribute is not verified during service provisioning. If more than 16 bytes of user data is specified on a call without the fast select option, then the call is cleared with a clear cause of 'local procedure error', and a diagnostic code of 39 (as defined in the ITU-T X.25 Recommendation).
