CHAPTER 5 SELF DIAGNOSIS
Cause
• The caller’s line is cut at phase 1 or the
caller’s signal is not detected.
Countermeasure
• Prohibit the caller’s V.8/V.34 protocol with
#1 SSSW-SW28 Bit 1.
Adjust the output level to a range of -8 to
-15dBm.
##0671 [RX] Line is released due to T1 time-out when the procedure does not proceed
beyond phase 2 after detection of CM signal on the calling side at the time a V.8 call is
received
Cause
• The recipient’s line is cut at phase 1 or the
recipient’s signal is not detected.
Countermeasure
• Prohibit the caller’s V.8/V.34 protocol with
#1 SSSW-SW28 Bit 0.
Adjust the output level to a range of -8 to
-15dBm.
##0672 [TX] Line is released due to T1 time-out when the procedure does not proceed from
phase 2 to beyond phase 3 during V.34 transmission
Cause
• The transmitter’s line is cut at phase 2 or
the transmitter’s signal is not detected.
Countermeasure
• Prohibit the caller’s V.8/V.34 protocol with
#1 SSSW-SW28 Bit 1.
Adjust the output level to a range of -8 to
-15dBm.
##0673 [RX] Line is released due to T1 time-out when the procedure does not proceed from
phase 2 to beyond phase 3 during V.34 reception
Cause
• The transmitter’s line is cut at phase 3 or
phase 4, or the recipient’s signal is not
detected.
Countermeasure
• Prohibit the caller’s V.8/V.34 protocol with
#1 SSSW-SW28 Bit 0.
Adjust the output level to a range of -8 to
-15dBm.
##0674 [TX] Line is released due to T1 time-out when the procedure does not proceed from
phase 3 and phase 4 to beyond the control channel during V.34 transmission
