Table G: DMS-100 Line and Trunk Trouble Codes

Trouble Code              Description
-----------------------------------------------------------------------------------------
ANNOUNCEMENT_MACH_TRBL    The Digital Recorded Announcement Machine (DRAM) failed to provide 
                          the required treatment to the line or trunk.
-----------------------------------------------------------------------------------------
ANI_NUMBER_FAILURE        The Automatic Number Identification (ANI) failed to identify the 
                          originating station on an outgoing toll call.
-----------------------------------------------------------------------------------------
ANI_OFFICE_FAILURE        The automatic number identification failed to identify the 
                          originating office on an incoming toll call.
-----------------------------------------------------------------------------------------
ANI_TEST_FAILED           The originating line card failed to identify the directory number. 
                          This indicates a defective ringing generator.
-----------------------------------------------------------------------------------------
ANI_TIME_OUT              The automatic number identification information was not received 
                          from the far-end office before the system timed out.
                          
			  The system generates this trouble code when Feature Group B (FGB) 
			  calls that encounter a trunk failure to the FGB carrier.  This 
			  failure occurs because an off-hook did not return in five seconds 
			  after outpulsing was complete.  The DMS-100 makes an attempt on a 
			  second trunk.  The DMS-100 removes the call.  The system generates 
			  this problem code only for FGB carriers that expect ANI spill.
-----------------------------------------------------------------------------------------
BAD_CP_IOMSG              Central control received a call processing message that was invalid.
-----------------------------------------------------------------------------------------
BAD_KEYSET_MSG            The system received a message from an add-on or extension not entered 
                          in user data table KSETINV.  The system received a key stroke that 
			  was invalid.
-----------------------------------------------------------------------------------------
BSS_SIC_INCOMPATIBLE      The BSS SIC is not compatible with the service required.
-----------------------------------------------------------------------------------------
BIPOLAR_VIOLATION         The system detected a transmission error on a DS-1, DS-2, or DS-3 
                          link.  A waveform that is bipolar can break the bipolar rule.  A 
			  1 pulse that has the same sign as the preceding 1 pulse breaks this 
			  rule. 
			  
                          Note: The system can use a violation deliberately to carry 
			  information outside the binary stream.
-----------------------------------------------------------------------------------------
CAMA_POSITION_FAULT       The system detected a Central Automatic Message Accounting (CAMA) 
                          position error during call processing.
-----------------------------------------------------------------------------------------
CAMA_POSITION_TROUBLE     The user reported the CAMA error manually with a 7-digit code.
-----------------------------------------------------------------------------------------






-----------------------------------------------------------------------------------------
CARRIER_OFFHK_TIMEOUT     A trunk failure to a Feature Group B (FGB) carrier occurred.  This 
                          failure occurred because an off-hook did not return in five seconds 
			  after outpulsing was complete.  The DMS-100 switch attempts a second 
			  trunk.  The DMS-100 removes the call.  This trouble code only occurs 
			  on trunks to FGB carriers that do not expect ANI spill.  For FGB 
			  carriers that expect ANI spill, trouble code ANI_TIME_OUT is sent.
-----------------------------------------------------------------------------------------
COIN_COLLECT_FL           Coins were not collected when the system processed a call that 
                          originated at a pay station.  This event normally indicates a 
			  stuck coin or the ringing generator failed to send the correct 
			  voltage.
-----------------------------------------------------------------------------------------
COIN_PRESENT_FL           The correct number of coins were not collected when the system 
                          processed a call that originated at a pay station.  This event 
			  normally indicates either a stuck coin or the ringing generator 
			  failed to send the correct voltage.
-----------------------------------------------------------------------------------------
COIN_RETURN_FL            The correct number of coins was not returned when the system 
                          processed a call that originated at a pay station. This event 
			  normally indicates either a stuck coin or the ringing generator 
			  failed to send the correct voltage.
-----------------------------------------------------------------------------------------
CP_IOMSG_LOST             Central control did not receive an expected call processing message.
-----------------------------------------------------------------------------------------
DIG_RCVR_NOISE_HIGH       The system detected a high level of noise on a digital multifrequency 
                          receiver.
-----------------------------------------------------------------------------------------
DIG_RCVR_NOISE_MARGINAL   The system detected some noise on a digital multifrequency receiver.
-----------------------------------------------------------------------------------------
DP_RCVR_NOT_RDY           The incoming dial-pulse trunk received pulses before the system 
                          prepared the trunk for digit collection.
-----------------------------------------------------------------------------------------
DU_SYNC_LOST              Data unit sync was lost as a result of slippage on the facility.
-----------------------------------------------------------------------------------------
EAOSS_HOLD_TIMEOUT        This code indicates problems with the line that is out of service. 
                          This code can indicate the timeout value specified in the office 
			  parameter.  The EA_OSS_HOLD_TIMEOUT_MINS is not long enough.
-----------------------------------------------------------------------------------------
EARLY_DP_DGT_DET          The system detected a problem during dial-pulse reception for an 
                          incoming call over a trunk.  As a result, the system did not 
			  determine the call destination.
-----------------------------------------------------------------------------------------
EMERGENCY_ANN             The system applied emergency announcement to the facility.
-----------------------------------------------------------------------------------------
EXCESS_DIGITS             The system received more digits than expected.
-----------------------------------------------------------------------------------------
EXPECTED_STOP_TIME_OUT    The system received expected stop-dial or timeout for call
                          processing or diagnostics.
-----------------------------------------------------------------------------------------
EXTRA_PULSE               The system received eleventh pulse for a single digit.
-----------------------------------------------------------------------------------------
FALSE_KP                  The system received second Key Pulse (KP) digit.
-----------------------------------------------------------------------------------------
FALSE_START               The system received second Signaling Terminal (ST) digit.
-----------------------------------------------------------------------------------------
GL_TIMEOUT                The system did not complete Multifrequency-Compelled (MFC) protocol 
                          global timeout in the specified timeout.  The MFC protocol global 
			  timeout is a full compel cycle.
-----------------------------------------------------------------------------------------
GRND_LOOP_FAIL            The system detected loop failure on termination to ground start.
-----------------------------------------------------------------------------------------


-----------------------------------------------------------------------------------------
HIT_DETECTED              The system detected a state change that did not last long enough 
                          to represent a valid signal on the signaling facility.
-----------------------------------------------------------------------------------------
IDDD_MISSING_TERMIND      The system received international direct distance dialing digits. 
                          The system did not receive a terminating digit before the system 
			  timed out.
-----------------------------------------------------------------------------------------
INTEGRITY_LOST            Incoming messages to the central control indicate both planes of 
                          the line or trunk equipment lost integrity.  A hardware problem 
			  can occur in the circuit card or in the facility.  A hardware 
			  problem can occur in the links between the peripheral and the 
			  network.
-----------------------------------------------------------------------------------------
INTEGRITY_FAILURE         The system did not receive off-hook trailing edge in the transmitter 
                          timeout period for delay dial trunks.
-----------------------------------------------------------------------------------------
INVALID_ANI_REQUEST       The system requested automatic number identification.
                          The system did not require ANI.
-----------------------------------------------------------------------------------------
INVALID_DIGIT_RECEIVED    This code indicates a Digitone receiver or a Universal Tone Receiver 
                          received one of the four digits that were not expected.  These digits 
			  come from a digital multi-tone frequency telephone.
-----------------------------------------------------------------------------------------
INVALID_RP_DIGIT          The system received invalid or incomplete routing information from 
                          the routing table.
-----------------------------------------------------------------------------------------
INWATS_BAND_CHECK         The system received a call from outside the acceptable INWATS zone.
-----------------------------------------------------------------------------------------
LARGE_TWIST               A digital multifrequency receiver detected a deviation from the 
                          expected frequency.
-----------------------------------------------------------------------------------------
LINE_CARD_FAULT           The Line Concentrating Module (LCM) detected a line card fault 
                          during call processing.
-----------------------------------------------------------------------------------------
LINE_DATA_ERROR           Sent from the International Line Group Controller (ILGC).
-----------------------------------------------------------------------------------------
LINE_FORMAT_ERROR         Sent from the ILGC.
-----------------------------------------------------------------------------------------
LINE_RESOURCE_FAILURE     Sent from the ILGC.
-----------------------------------------------------------------------------------------
LINE_SIGNALLING_FAILURE   Sent from the ILGC.
-----------------------------------------------------------------------------------------
MAN_UNREC_STRING          The system did not recognize a required string.
-----------------------------------------------------------------------------------------
MFC_TONE_OFF              The originating trunk sends a tone before this trunk receives an 
                          acknowledge from the incoming trunk.  The originating trunk sets 
			  the tone off.
-----------------------------------------------------------------------------------------
MISDIRECTED_CAMA          The system received the prefix digit 1+ or 011+ for a call that 
                          does not require the prefix digit.  The system routed the call 
			  to a misdirect CAMA treatment.
-----------------------------------------------------------------------------------------
MISSING_CLC               The CLC is not present.
-----------------------------------------------------------------------------------------
MISSING_STRINGS           The message does not contain required strings.
-----------------------------------------------------------------------------------------
MISSING_TERMIND           The system received digits.  The system did not receive a 
                          terminating digit during timing out.
-----------------------------------------------------------------------------------------
MORE_THAN_TWO_FREQS       The digital multifrequency receiver received more than two
                          frequencies.
-----------------------------------------------------------------------------------------

-----------------------------------------------------------------------------------------
MUTILATED_DIGIT           The digital multifrequency receiver received either less than two 
                          frequencies, more than two frequencies, or frequencies that were 
			  not correct.  A bad analog-to-digital or digital-to-analog converter 
			  in the trunk module that houses the receiver can cause defective 
			  digits.
-----------------------------------------------------------------------------------------
MUTILATED_PULSE           The system received an elongated pulse between 80 ms and 200 ms.
-----------------------------------------------------------------------------------------
NIL_TRB_CODE              The system detected a problem that is not defined during call.
-----------------------------------------------------------------------------------------
NO_CIRCUIT_AVAILABLE      There was no circuit available to complete the call.  The system 
                          routed the call to an All Trunks Busy treatment.  This code 
			  indicates a busy verify tone circuit was not available at the time 
			  of a call barge in.
-----------------------------------------------------------------------------------------
NO_INTERDIGIT_PAUSE       The digital multifrequency receiver did not detect a pause between 
                          digits received.
-----------------------------------------------------------------------------------------
NO_START_DIAL             The system did not receive off-hook trailing edge in the transmitter 
                          timeout period for delay dial trunks.  This code can indicate the 
			  system did not receive a valid wink in the transmitter timeout period 
			  for on-wink trunks.
-----------------------------------------------------------------------------------------
NO_UTR_AVAILABLE          The XPM ran out of UTR channels and cannot service the request.
-----------------------------------------------------------------------------------------
NO5_SIGNALLING_VIOLATION  The system detected a problem in the CCITT No. 5 compelled signaling 
                          sequence.
-----------------------------------------------------------------------------------------
OPT_UNREC_STRING          The system does not recognize an optional string.
-----------------------------------------------------------------------------------------
OUTPULSE_TIME_OUT         The system did not receive compelled tone for outgoing trunk in the 
                          specified timeout period.
-----------------------------------------------------------------------------------------
OVERALL_RP_TIMEOUT        The remote peripheral timed out and did not receive digits or signals.
-----------------------------------------------------------------------------------------
PARSER_SYNTAX_ERROR       The system detected a syntax error in the message.
-----------------------------------------------------------------------------------------
PARTIALDIAL               The receiver did not receive enough digits before the receiver timed 
                          out.  The receiver received a minimum of one digit.
-----------------------------------------------------------------------------------------
PERMANENT_SIGNAL          The system detected permanent signal on the line equipment.  The 
                          system did not collect any digits.  This code normally indicates a 
			  hardware problem with either the line card or facility.
-----------------------------------------------------------------------------------------
PRE_ROUTE_ABANDON         The system abandons an incoming call before the system receives all 
                          digits and determines a route.  Pre-route abandon normally occurs 
			  when the system detects an on-hook during outpulsing.
-----------------------------------------------------------------------------------------
PSTN_BARRED               The originator is barred from connection to the PSTN.
-----------------------------------------------------------------------------------------
PULSE_ON                  A tone considered to be a pulse continues longer than the time 
                          specified.  The log report provides the pulse MFC_signal.
-----------------------------------------------------------------------------------------
REVERSED_TRUNK            The system detected either a polarity that is not correct or a 
                          continuity failure for a loop signaling trunk.
-----------------------------------------------------------------------------------------
RINGING_FAILED            The system detected a problem that is not expected with the ringing 
                          generator.  The system did not ring the line.
-----------------------------------------------------------------------------------------
SIC_INCOMPATIBLE          The received SIC was not compatible with the service required.
-----------------------------------------------------------------------------------------
SWAP_REJECT               The system rejected the swap message.
-----------------------------------------------------------------------------------------
-----------------------------------------------------------------------------------------
TELLTALE                  The system abandoned an incoming call over a trunk from a remote 
                          peripheral.
-----------------------------------------------------------------------------------------
TONE_ON                   For an outgoing trunk, the compelled signal persists even when the 
                          trunk does not send the compelling signal any longer.  For an incoming 
			  trunk, the compelling signal persists even when the compelled signal 
			  starts.  The log message provides the received MFC signal.
-----------------------------------------------------------------------------------------
TRUNK_RESET               The system reset the trunk during call processing.
-----------------------------------------------------------------------------------------
TRUNK_RESET_FAILED        The system did not reset the trunk after the system released the call.
-----------------------------------------------------------------------------------------
UNAUTHORIZED_CODE         Number dialed was not valid for the line or trunk class.  The system 
                          routed the call to the unauthorized code treatment.
-----------------------------------------------------------------------------------------
UNDEFINED_MFC_SIG         The system received a Multifrequency-Compelled (MFC) signal that 
                          does not have description.  Table MFCACT did not define this signal.
-----------------------------------------------------------------------------------------
UNDETERMINED_RP_ERROR     The system detected problems in the remote peripheral that are not 
                          known.
-----------------------------------------------------------------------------------------
UNEXPECTED_MFC_SIG        The system received an MFC signal that the system does not expect 
                          in the current context.
-----------------------------------------------------------------------------------------
UNEXPECTED_MSG            The system recognized a message.  The system received this message 
                          during a phase of the call that is not correct.
-----------------------------------------------------------------------------------------
UNEXPECTED_STOP_DIAL      The system displays this message for one of three reasons:

                           * Any off-hook (stop-dial) during outpulsing for Multifrequency 
			     (MF) trunks.

                           * A stop-dial did not meet the acceptable stop-go expected for 
			     Dial-Pulse (DP) trunks.

			   * A stop-dial was received before outpulsing began for dial-pulse 
			     immediate dial trunks.
-----------------------------------------------------------------------------------------
UNRECOGNIZED_MSG          The system did not understand a message.
-----------------------------------------------------------------------------------------
UTR_HI_NOISE              The Universal Tone Receiver (UTR) is detecting excessive noise on 
                          the trunk and cannot continue detecting Multifrequency-Compelled
			  (MFC) tones accurately.
-----------------------------------------------------------------------------------------
UTR_LARGE_TWIST           Twist occurs when the power of one frequency in the signal is greater 
                          than the power of the second frequency.  The difference in frequency 
			  is normally caused by characteristics of the trunk.  If this
			  difference is greater than a preset level, normally 9 dB, this is 
			  considered an error.
-----------------------------------------------------------------------------------------
UTR_MUTIL_DIGIT           The UTR received less than, or more than, two frequencies.  
                          This indicates possible hardware problems.
-----------------------------------------------------------------------------------------
VACANTCODE                The system could not determine the destination from the digits 
                          received, and the system routed the call to a vacant code treatment.
-----------------------------------------------------------------------------------------
VALID_CALLING_NUMBER      The automatic number identification failed, but the Operator 
                          Number Identification (ONI) succeeded.
-----------------------------------------------------------------------------------------




-----------------------------------------------------------------------------------------
WRONG_ANI_REQUEST         An FGB carrier encountered a trunk failure because the system received 
                          a wink instead of the expected off-hook after completing outpulsing. 
			  The DMS-100 switch takes down the call.  This trouble code only occurs 
			  on trunks to FGB carriers that expect an ANI spill.
-----------------------------------------------------------------------------------------
WRONG_SUPERVISORY_SIGNAL  An FGB carrier encountered a trunk failure because the system received 
                          a wink instead of the expected off-hook after completing outpulsing. 
			  The DMS-100 switch takes down the call.  This trouble code only occurs 
			  on trunks to FGB carriers that do not expect an ANI spill.
