Item i) attempts to abort the entire Exchange with ABTS-LS (ABTS Basic
Service with the Parameter field bit 0 set to zero).

detects an E_D_TOV
waiting for the ACK frame in response to the ABTS, it shall abort the
Exchange using ABTSLS,
if conditions permit, and retry the original ELS with a different
i) If the Sequence Initiator attempts to abort a Sequence using ABTS-LS
it detects an
E_D_TOV waiting for the ACK frame in response to the ABTS-LS, it may
