**课程名称：** 固定电话与宽带网络 **课程概述：** 本课程旨在为学员提供对固定电话和宽带网络的全面理解。 * **固定电话网络基础：** 课程从最古老的固定接入网络概念——电话线开始，介绍其带宽需求（300赫兹至3300赫兹）、最初专为语音传输设计的特点以及模拟传输技术。学员将学习基础电话终端、调制解调器以及本地线路的基本概念。 * **交换系统：** 课程随后深入探讨用于确定呼叫路由路径的交换系统，这些系统存在于本地交换局、中心局或长途交换局中。交换系统主要分为两种： * **电路交换（PSTN）：** 在此模式下，连接是独占的，例如传统的电话网络。 * **分组交换（互联网）：** 数据流被分割成数据包，每个数据包独立传输，并在目的地重新组装。 * **PSTN网络细节：** 课程还将涵盖PSTN网络的层级结构、编号方案和呼叫流程。 * **数据与互联网服务：** 课程也讨论了固定接入网络提供的数据服务或互联网服务。 * **关键术语：** 最后，课程将介绍与固定接入网络相关的各种术语，包括ISDN、VPN、DSL、ADSL、FTTx、TX-IP或MPSL等。 **学习评估：** 课程设有评估测验，帮助学员检验学习成果。
The course is designed to give the participants good understanding of Fixed line and Broadband Network. Fixed Line of Telephone line is the oldest concept that we can correlate to in terms of Fixed access network. The bandwidth requirement for Voice and Data over fixed access networks is between 300 Hertz to three thousand three hundred Hertz. This system was originally designed for voice transmission only, using analog transmission technology on a single voice channel. Participants will learn about basic telephone terminal, modem and some basic concepts about local loop. The course content then move towards the switching system which is used to determine the routing pathway of the call. Switched are contained in local exchanges, and central offices or tandem exchanges. Switching systems can be broadly classified as Circuit Switching or PSTN and Packet Switching or Internet. Circuit Switching can be done as time switching, in which switching is done between time slots. In packet switching, each data stream is divided into chunks, called packets; each packet is sent separately into the network. The course also covers the PSTN Network hierarchy, numbering scheme and call flow. The course includes aspects of the data services or internet services provided by fixed access network. The course concluded covering various terminologies related to fixed access network like ISDN, VPN, DSL, ADSL , FTTx, TX-IP or MPSL. Assessment quiz at the end of the course will help participants to check their learning.
