mscFrUniSigX213IeHandling 1.3.6.1.4.1.562.36.2.1.71.6.12.1.17

The x213IeHandling attribute specifies how Frame Relay handles the X.213 Priority IE when it is in the FRF.4 setup message. When the attribute is set to notSupported, the X.213 Priority IE will not be recognized in the setup message. A FRF.4 status message will be sent to the calling DTE, with the indication that an unrecognized IE was encountered. The call setup then proceeds as normal, and the X.213 Priority IE does not appear in the setup message at the called end. When the attribute is set to proprietary, and the X.213 Priority IE is present in the FRF.4 setup message, it will be recognized. If there is no Frame Transfer Priority IE in the setup message, the first data byte of the X.213 Priority IE is used to select the transfer and discard priority values for the connection and the X.213 Priority IE is signaled to the called end in the setup message. If the Frame Transfer Priority IE is present in the FRF.4 setup message, its value is used to select the transfer priority, the discard priority is taken from the FRUNI Dna component, and the X.213 Priority IE is ignored. Refer to the related Application Note for further details before setting the attribute value to proprietary.
