    Automated attendant 
    inoperative User error 
    ECTIVE ACTION 
    A DTMF phone is required. Refer to 
    FEATURES, page 4-13. 
    DTMF decoder 
    unavailable If a DTMF decoder is not available, the 
    caller is transferred to the automated 
    attendant’s attendant. 
    Programming error 
    Automated attendant station(s) must be 
    designated in the database. Refer to 
    PROGRAMMING, pages 5-49 and 5-87. 
    Defective playback 
    device Replace the playback device. 
    NOTE: Due to the natural characteristics of the C.O. line, the volume level of DTMF tones transmitted over the 
    line may be substantially reduced before reaching the GMX-48 System. This natural degradation in tone volume 
    mayadverselyaffect the reliability of the automated attendant feature. 
    Other factors which can affect automated 
    attendant performance are C.O. line noise, the quality of the playback device, and the quality and sfrength of the 
    DTMF tones generated by the off-premises phone itself.

    included with the unit to verify the wiring 
    interface and installation. 
    Refer to FEATURES, page 4-22, and to 
    PROGRAMMING, page 5-75. 
    Some voice mail units require DTMF 
    feedback from the KSU to indicate the status 
    of the call being attempted. For other voice 
    mail units, DTMF feedback may cause 
    problems and should be disabled. 
    SMDA reports not generated 
    automatically and/or they 
    cannot be generated using 
    the attendant feature code Programming error 
    Automatic SMDA report generation must be 
    be enabled. Also, the reports can be set to be 
    generated daily, weekly, monthly, or by the 
    attendant only. See PROGRAMMING, 
    page 5-112.

    For correct procedures on using the attendant 
    feature code for SMDA report generation,

    SYMPTOM PROBABLE CAUSE CORRECTIVE ACTION 
    Keyset squeals on outside 
    calls or when receiving 
    a handsfree intercom 
    call from a single-line 
    station (feedback) Speaker volume is too 
    loud 
    Poor acoustics Reduce feedback by lowering speaker 
    volume using keyset volume controls. 
    Poor acoustics can cause poor quality on 
    handsfree calls. Try placing a private call. 
    NOTE: A two- to four-wire converter is used during communication between keysets and single-line stations. 
    Reflection is a normal characteristic of these converters. Feedback on intercom calls is eliminated when the sing- 
    le-line station user places a private intercom call by pressing the pound (#) key before dialing the intercom num- 
    ber or by entering the ring intercom always feature code (367). 
    Data noise in any off-hook 
    condition Defective cabling or 
    connections Check for loose or open connections, or
