Modem CC Connection Fail Reason
Indicates the reason that the last connection or attempt failed. The meaning of each reason code is explained below. unknown: This code means the failure reason is unknown or there has been no previous call. other: This code used when no other code is applicable. Additional vendor information may be available elsewhere. managementCommand: A management command terminated the call. These commands include escaping to command mode, initiating dialing, restoring lines, and disconnecting. inactivityTimeout: The call was terminated because it was inactive for at the minimum duration specified. mnpIncompatibility: The modems are unable to resolve MNP protocol differences. protocolError: An error occured in one of protocol in use. Further information is required to determine in which protocol the error occurred, and the exact nature of the error. powerLoss: The modem lost power and disconnected the call. equipmentFailure: The modem equipment failed. dtrDrop: DTR has been turned off while the modem is to disconnect on DTR drop. (Ref: V.58 cct108TurnedOff) noDialTone: If the modem is to monitor
for call progress tones, but the modem has failed to detect dial tone while attempting to dial a number. lineBusy: Busy signal is detected while busy signal detection is enabled, or while the 'W' or '@' dial modifier is used. (Ref: V.58 engagedTone) noAnswer: The call was not answered. voiceDetected: A voice was detected on the call. carrierLost: Indicates that the modem has disconnected due to detection of loss of carrier. In TIA-602, the S10 register determines the time that loss of carrier must be detected before the modem disconnects. trainingFailed: Indicates that the modems did not successfully train and reach data mode on the previous connection. faxDetected: A fax was detected on the call.
