This attribute indicates the allowable packet sizes supported for
calls setup using this DNA. To set a given packet size to be allowed
on the DNA, the packet size is entered, and the corresponding bit in
the structure is set to a value of 1. To set a given packet size to be
disallowed on the DNA, the packet size is entered preceeded with
the '~' character, and the corresponding bit in the structure is set to a
value of 0. CCITT recommends that packet size 128 always be
supported.
