Table 1.6 describes the OOB signal receiver requirements for detecting burst
times, assuming Tburst is the length of the detected burst time. The burst time is
not used to distinguish between signals.

Table 1.7 describes the OOB signal receiver requirements for detecting idle times,
assuming Tidle is the length of the detected idle time.

Table 1.8 describes the OOB signal receiver requirements for detecting negation
times, assuming Tidle is the length of the detected idle time.
Table 1.8 OOB signal receiver negation time detection requirements
Signal
COMINIT/COMRESET
COMSAS
A receiver shall detect an OOB signal after receiving four consecutive idle
time/burst time pairs. It is not an error to receive more than four idle time/burst
time pairs. A receiver shall not detect the same OOB signal again until it has
detected the corresponding negation time (i.e., a COMINIT negation time for a
COMINIT) or has detected a different OOB signal.
A SAS receiver shall detect OOB signals comprised of ALIGNs transmitted at
any rate up to its highest supported physical link rate. This includes physical link
rates below its lowest supported physical link rate (e.g., a SAS receiver
supporting only 3,0 Gbps detects 1,5 Gbps based ALIGNs, providing
interoperability with a SAS transmitter supporting both 1,5 Gbps and 3,0 Gbps).
