Tx/Rx Description
[Tx] at time of ECM transmission, no meaningful signal is received after transmission of
EOR-NULL, causing the procedural signal to be transmitted more than specified.
[Tx] at time of ECM transmission, DCN is received after transmission of EOR-NULL.
[Tx] at time of ECM transmission, the procedural signal has been transmitted more than
specified after transmission of EOR-NULL, or T5 time-out (60 sec) has occurred.
[Tx] at time of ECM transmission, ERR is received after transmission of EOR-NULL.
[Tx] at time of ECM transmission, no meaningful signal is received after transmission of
EOR-MPS, causing the procedural signal to be transmitted more than specified.
[Tx] at time of ECM transmission, DCN is received after transmission of EOR-MPS.
[Tx] at time of ECM transmission, the procedural signal has been transmitted more than
specified after transmission EOR-MPS, or T5 time-out (60 sec) has occurred.
[Tx] at time of ECM transmission, ERR is received after transmission of EOR-MPS.
[Tx] at time of ECM transmission, no meaningful signal is received after transmission of
EOR-EOM, causing the procedural signal to be transmitted more than specified.
[Tx] at time of ECM transmission, DCN is received after transmission of EOR-EOM.
[Tx] at time of ECM transmission, the procedural signal has been transmitted more than
specified after transmission of EOR-EOM, or T5 time-out (60 sec) has occurred.
[Tx] at time of ECM transmission, ERR is received after transmission of EOR-EOM.
[Tx] at time of ECM transmission, no meaningful signal is received after transmission of
EOR-EOP, causing the procedural signal to be transmitted more than specified.
[Tx] at time of ECM transmission, DCN is received after transmission of EOR-EOP.
[Tx] at time of ECM transmission, the procedural signal has been transmitted more than
specified after transmission of EOR-EOP, or T5 time-out (60 sec) has occurred.
[Tx] at time of ECM transmission, ERR is received after transmission of EOR-EOP.
[Rx] at time of ECM reception, ERR is transmitted after transmission of EOR-Q.
[Tx/Rx] while ECM mode procedure is under way, a signal other than a meaningful signal
is received.
[Rx] at time of ECM reception, PPS-NULL cannot be detected over partial page
processing.
[Rx] at time of ECM reception, no effective frame is received while high-speed signal
reception is under way, thus causing time-out.
[Tx] at time of ECM reception, PPR with all 0s is received.
[Tx/Rx] a fault has occurred in code processing for communication.
