This read-write object indicates whether to accept, transfer, and deliver the Broadband Low Layer Information Element from the calling party to the called party. This IE carries details about the lower-layer protocol stack, such as AAL type and parameters, the caller intends to use, so if this is disabled the called party never receives that description and may default to assumptions that don't actually match the caller's intent, risking a connection that comes up but can't exchange usable data. A caller specifying AAL5 parameters via this IE that never reach the called device because this is disabled could result in the two ends assuming different frame-size limits.
