Indicates the multiples of the SDU for each algorithm that occur. Service data units (SDUs) for audio are defined in relation to the profile of encoding formats adopted on a given AAL type 2 connection. Each algorithm that occurs in a given profile may appear in multiple entries corresponding to packets of different lengths. These packet lengths shall align in a simple sequence, whereby each is an integral multiple of the smallest packet length that occurs for the algorithm (at a given bit rate). The smallest packet length is the SDU of the algorithm, in relation to the given profile. Valid values are 1..8. The default is 1 octets.
