1.3.6.1.4.1.562.2.4.1.60.2.2.11.1.1
This attribute specifies the type of framing protocol that will be used for frames transmitted to the link interface and received from the link interface. If the value of this attribute is set to the default interrupting, then a Proprietary hdlc protocol is used which allows for voice cells to interrupt transmission of data frames, transmit the voice cell, and then continue transmitting the data frame. If the value of this attribute is set to hdlc, then the standard hdlc procotol is used for the sequential transmission of individual frames.
