White Paper Abstract:
This document is directed to competitive local exchange carriers (CLECs), incumbent local exchange carriers (ILECs), and Post, Telephone, and Telegraphs (PTTs), telephone companies collectively referred to as telcos. This document describes Cisco network solutions for transporting data between various transmission network elements and the Operations Support System (OSS) in a telco's data communications network (DCN). The DCN transports network management traffic between network elements and their respective OSS, making them a vital link between the service network and the network operations center (NOC). The solutions presented in this document will help telcos migrate transmission equipment that use the X.25 protocol to a router-based TCP/IP network. The solutions will help service providers migrate their OSSs with an X.25 interface onto a TCP/IP backbone.
