How to Properly Add QAM
Elements to the DNCS
Overview
Introduction
When adding Quadrature Amplitude Modulation Modulator (QAM) elements to the
Digital Network Control System (DNCS), operators must allow an adequate amount
of time to pass between adding each element. Adding QAM elements to the DNCS
in quick succession may cause the DNCS to become non-responsive. System
operators can successfully add multiple QAM elements to the DNCS and ensure
constant system operations by following the instructions in this document.
Purpose
This document explains how to properly add QAM elements to the DNCS to ensure
constant system operations. Failure to follow the instructions described in this
document may cause the system to become non-responsive.
Audience
This document is written for system operators who use Cisco's DNCS. Cisco
engineers may also find this document to be useful.
