atmPrefixProfile-UseShortAddress 1.3.6.1.4.1.529.23.22.1.1.2

Applies to default address generated using this profile's prefix. Flag == NO (default) value means, default address generated will always be 20 byte long. FLAG == YES value means, default address generated could be less than 20 byte. Also algorithm used to generate is different based on this flag's value. use-short-address == FALSE, in NSAP structure, ESI byte is coded as follows. FF MSB MSB-1 MSB-2 LSB PortNumber. In case short-flag == TRUE, in NSAP structure, immediately after Prefix length, following 8 bits are used for the slot number and subsequent 8 bits are used for the port number.
