• V.8/V.34 protocol error codes
##0670 [TX] At V.8 late start, the called party declares the V.8 protocol in DIS
signal and this unit transmits a CI signal, but the protocol does
not progress and a T1 time-out occurs.
Cause: The other party disconnected the line while the CI signal was being
transmitted, or ANSam/DIS from the called party was not able to be
detected.
Solution: Increase #2 MENU No.07 transmission level within a range of
-8~-15 (dBm) or set #1 SSSW SW-28 bit 0 to "1" to inhibit the V.8/V.34
protocol on calling.
##0671 [RX] At V.8 termination, the protocol did not advance to phase 2 and
a T1 time-out occurs after the caller CM signal was detected.
Cause: The caller disconnected the line or the signal from the caller was not able
to be detected.
Solution: Increase #2 MENU No.07 transmission level within a range of
-8~-15 (dBm) or set #1 SSSW SW-28 bit 1 to "1" to inhibit the V.8/V.34
protocol for the called party.
##0672 [TX] The protocol did not move from phase 2 to phase 3 and a T1
time-out occurred during V.34 transmission.
Cause: The called party disconnected the line during phase 2 or the signal from
the called party was not able to be detected.
Solution: Increase #2 MENU No.07 transmission level within a range of
-8~-15 (dBm) or set #1 SSSW SW-28 bit 0 to "1" to inhibit the V.8/V.34
protocol on calling.
##0673 [RX] The protocol did not move from phase 2 to phase 3 and a T1
time-out occurred during V.34 reception.
Cause: The transmitter disconnected the line during phase 2 or the signal from the
transmitter was not able to be detected.
Solution: Increase #2 MENU No.07 transmission level within a range of
-8~-15 (dBm) or set #1 SSSW SW-28 bit 1 to "1" to inhibit the V.8/V.34
protocol on termination.
##0674 [TX] The protocol did not move from phase 3 to phase 4 and a T1
time-out occurred during V.34 transmission.
Cause: The called party disconnected the line during phase 3 or the signal from
the called party was not able to be detected.
Solution: Increase #2 MENU No.07 transmission level within a range of
-8~-15 (dBm) or set #1 SSSW SW-28 bit 0 to "1" to inhibit the V.8/V.34
protocol on calling.
