Phase Description of Problem
B Transmitter sent NSS (or DCS) followed
by TCF three times, but the receiver did
not respond. (CFR or FTT is usually
returned)
B Transmitter received FTT after it trans-
mitted TCF at 2400bps.
Received RTN after communicating at
2400 bps.
D Transmitter received no response after it
transmitted post message, such as
EOP, MPS, EOM, etc, or received DCN.
D Transmitter received RTN after it trans-
mitted EOP, MPS, or EOM.
D Transmitter receives PIN after it trans-
mitted a post message, such as EOP,
MPS, EOM, etc.
D Received DCN while waiting for post
command. (EOP, MPS, EOM, etc.)
B Received DCN after transmitting NSC.
B No response within 12 seconds in NSS/
D DCS/MPS wait state. (After transmitting
FTT, MCF, or CFR)
B No response received after transmitting
3rd NSC.
B Remote side attempted to receive mes-
sage from your machine in polling com-
munication. "Inform the remote side that
your machine does not have the polling
transmission feature."
D Receiver did not detect post command,
such as EOP, MPS, EOM, etc.
