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.
-----------------------------------------------------------------------------------------
XPM_TRAP Sent by the International Line Group Controller (ILGC).
