  • Page 13: Configuration

    DX-80 Installation & Maintenance 1.2 Configuration The Comdial DX-80 platform is comprised of one full-featured key telephone model and two modular KSUs (Key Service Units). Several modules are available for enhanced system applications and con- figuration expandability. 1.2.1 KSU1 COMPONENTS The CPM (Central Processor Module) is installed inside of KSU1 to the 408M ribbon cable J4 (also labeled “To CPM”).

  • Page 14: Voice Processing Modules

    The DX-80 provides several voice processing (or voice mail) options. The optional voice processors that you can add to the DX-80 are fixed system resources that do not require peripheral device ports (analog or digital). This significant advantage means that the DX-80 VP options can be added to any DX-80 configuration without “port loss”...

    You can service the system, using PC-DBA and a modem in your PC, to place a call to the site where the DX-80 is installed. Note: If one of the voice processing systems are installed, routing to the modem extension is automated. Otherwise, the person who answers this data call must transfer the call to extension 199.

    The Automated Attendant Module is a self contained integrated module that enables automatic answering of selected CO lines and a single-level menu for greeting callers and routing them to DX-80 system destinations. The AAM can handle all call traffic or act as a backup to the primary answering system attendant.

The installation of the DX-80 is complete only when this critical operation is performed. Occa- sionally it may be required to perform this initialization process after the original installation, but this is rare.
  • Page 68 Comdial ships the DX-80 with the option strap in the COLD START position to preserve the battery while the system is in transit. However, you MUST move this strap to NORMAL for the DX-80 to begin normal operation.

    The system trouble shooting procedures are a logical approach to fault identification, analysis, and cor- rection. The DX-80 may generate symptoms of problems that actually occur outside of the office envi- ronment. Problems such as system restarts (from temporary AC power interruption), fading (from the long distance carrier), or dropped calls (caused by internal users randomly pressing holding CO line buttons) all are common situations that are not the result of a system component or software failure.
