The Cisco VCO/4K Troubleshooting Guide provides information that will enable you to properly diagnose and resolve many of the problems that you may encounter with the VCO/4K system. Problems that cannot be resolved with the information in this guide must be elevated to a Cisco TAC (Cisco Technical Assistance Center). Procedures to ensure accuracy and timeliness of your input are also contained in this guide.
The guide provides users and technicians with information on performing corrective maintenance routines for peripheral equipment, power subsystem, interface circuits, service and control circuits, and host communication links. It also serves as a reference guide on the diagnostic tools incorporated in the system.
This guide concentrates on fault isolation and refers to descriptions, procedures, and tools used to remedy a problem within a specific system component. It contains first-level troubleshooting information for the VCO/4K system and associated components. Procedures reference additional information contained in various other documents in the VCO/4K documentation set. Corrective maintenance procedures for individual VCO/4K system components may be called upon from more than one source within this guide (that is, a troubleshooting procedure may apply to several symptoms). These internal cross-references tie sections of this guide together.
Original equipment manufacturer (OEM) documents contain details on maintaining the peripheral equipment (console, printer, and modems) connected to a VCO/4K system. Specialized OEM telecommunications equipment (such as voice response units, voice store-forward subsystems, telsets, etc.) are also available with similar documentation. Refer to these OEM documents when performing preventive and corrective maintenance.
This manual is intended for VCO/4K system users and third-party support personnel. If you are unfamiliar with the VCO/4K system, refer to one or more of the related documents listed in the "Related Documentation" section.
This manual assumes that the host application (if it is a hosted system) is written to conform to the VCO API Programming Reference Manual. However, that does not preclude problems occurring between the application and the VCO/4K system.
Each release of the VCO/4K Generic is described in the Cisco VCO/4K Release Notes that contain detailed information on changes from one release to the next. If your VCO/4K System includes the SS7 subsystem, refer to the SS7 Release Notes.
This document is organized as follows:
