The DHCT Status Reporting Utility
Digital Home Communication Terminals (DHCTs) that are unable to establish or
maintain two-way communication with the headend are known as non-responding
DHCTs. The DHCT Status Reporting Utility was developed to help system operators
and Cisco engineers minimize the impact of non-responding DHCTs on the DBDS
network.

The signonCount Utility
DHCTs lose the contents of their volatile memory, including network configuration
The signonCount Utility
DHCTs lose the contents of their volatile memory, including network configuration
data, whenever they download new operating system or resident application
software, or any time they reboot. As a part of the reboot process, DHCTs sign back
on to the network and the contents of their volatile memory are updated. The
signonCount Utility is useful in helping system operators monitor the rate at which
DHCTs sign on to the network. In addition, the utility can automatically fix common
problems that prevent DHCTs from signing on.
Installation of the Utilities
Installation of the DHCT Status Reporting Utility and the signonCount Utility occurs
automatically when you install the DBDS Utilities. Refer to DBDS Utilities Installation
Instructions and DNCS Utilities User’s Guide, part number 740020, for installation
instructions for the DBDS Utilities.
Audience
This guide is written for the system operators of Cisco’s digital cable television
systems and Cisco field service engineers who help system operators manage their
systems.
