failure to respond, IPFax terminated the call. This can be caused by the remote
device hanging up without notifying the TDM network (POTS lines lack such
notification), line impairment such that the gateway could not detect and
encode the MCF command, line noise such that our MPS was not detected by
the remote device, or packet loss such that either the MPS or the response MCF
was lost, or latency such that the MCF or MPS was delayed. In the case of
packet loss, insure that low-speed redundancy is enabled. Error type:
RETRYABLE
.
30215 Invalid response after end-of-page:
After sending the end of
page command to the remote, the remote should have sent a MCF, PIP, RTP,
PIN, or RTN response. It sent something else. Error type:
RETRYABLE
.
30216 Receiver sent DCN:
Normally, the receiver should never send a DCN
disconnect signal. This could be due to line impairment causing a timeout on
the receive side, or a user manually pressing a cancel button on the receiving
fax machine. Error type:
RETRYABLE
.
30217 Invalid response to
ECM block: The valid responses from the
remote following the transmission of an ECM block should be RNR, PPR or MCF.
Some other signal was received. Error type:
NON_RETRYABLE
.
30218 Remote fax not ready for next page:
The T5 timeout (60
seconds ± 5 seconds) occurred while exchanging RR and RNR signals for an
ECM send. Error type:
RETRYABLE
.
30219 No response to
ECM end-of-page: The sender had received a
RNR at which time it responds with an RR signal. It then expects the remote to
send either a RNR or an MCF within T4 seconds. There was no response
received. Error type:
RETRYABLE
.
30220 No more baud rates to try:
After a 4th ppr signal is received, a
CTC signal is sent so as to step down the baud to the next configured baud rate.
All configured baud rates have been exhausted. Error type:
RETRYABLE
.
30221 No response to CTC:
No response after CTC. Error type:
RETRYABLE
.
30222 Invalid response to CTC:
The expected signal after CTC is CTR.
Some other signal was received. Error type:
RETRYABLE
.
30223 Invalid response after
ECM block: After receiving an ECM block,
the expected signals are PPS, CTC or RR. Some other signal was received. Error
type:
NON_RETRYABLE
.
30224 Unexpected DCN:
During receive, a DCN signal was received at a
point where it is not expected. This most commonly occurs under ECM. For non-
ECM faxes, a DCN received after page data does not generate an error since
some fax machines don’t bother with a post page signal on the last page. Error
type:
NON_RETRYABLE
.
30225 The sender specified a modulation that is not suppor ted:
The DCS has an invalid baud rate/modulation specified. Error type:
NON_RETRYABLE
.
30226
ECM required for V.34: The remote does not support error
correction mode which is required for the V.34 connection that was established.
Error type:
RETRYABLE
.
