Managing Duplicate IP Addresses in
the Field Technical Reference
the Field Technical Reference
Overview and Background
Introduction
Through the years, Cisco engineers have noticed a steady flow of reports from the
field whereby the Digital Network Control System (DNCS) assigns an IP address
to a Digital Home Communications Terminal (DHCT), even though that IP
address is still in use with another DHCT. This duplication of IP address
assignments has resulted in a substantial amount of chronic non-responding
DHCTs in the field, as well as a potential loss of revenue to system operators.
Two main causes for this issue have been identified:

Site support staff assigns an administrative state of out-of-service to two-way
DHCTs, then back to in-service two-way, in an attempt to fix various
subscriber-based field issues.

Purpose
This document serves to explain what happens internally on the DNCS when a
DHCT is assigned a status of out-of-service. Additionally, this document offers
guidance to system operators on how to properly handle subscriber non-payment
and DHCT headend troubleshooting issues.

Audience
This document is written for system operators and headend administrators of the
DBDS who are responsible for maintaining an accurate administrative status of
DHCTs in their inventory. Field service engineers who assist in maintaining the
headend will also find this bulletin to be useful.
