Introduction
Wide Area Network (WAN) is a data communications network that connects users in a network that was in a large geographic area. WAN has several important characteristics that distinguishes it from the LAN. In the first lesson in this module will discuss the introduction of WAN technologies and protocols. And also will explain how the similarities and differences between the WAN and LAN.
It is very important to understand the physical layer components in a router. This will increase the knowledge base of information and capabilities that will be required to configure the router and set up the network routing. This module also describes the techniques of the physical connection of various router interfaces.

1.1 Introduction WAN
WAN is a data communication network that is spread on a large geographic area such as provinces or states. WAN always uses transmission facilities provided by telecommunications companies such as telephone service companies.
Characteristics of WAN:
- Connect the equipment that spread to a wide geographic area
- Using public service channels, such as telecommunications companies. PT. Telkom, PT. Indosat, PT. Excelcomindo and others to form a network within the geographic area.
- Using the serial connections to access bandwidth throughout the geographic area.
WAN different from the LAN. Unlike LAN-connected workstation workstations, equipment, terminals and other equipment dalan a building, WAN connecting the data in a wide geographic area. Companies that use the WAN can connect between headquarters and branch offices are located at a distance.
A WAN operates at the physical layer and data link layer of the OSI layer. WAN connects LANs within a large geographic area. WAN capable pertukakaran and frame data packets between the routers and switches.
Here are the tools used in the WAN:
- Router, including internetworking and port-port WAN interface
- Modem, including voice-grade interfaces, channel service units / digital service units (CSU / DSU) that serves T1/E1 interfaces, and the Terminal Adapter / Network Termination 1 (TA / NT 1) as an interface Integrated Services Digital Network (ISDN)
- Server-server dial-in and user-user who does dial out to connect
WAN handling standards:
- International Telecommunication Union-Telecommunication Standardization Sector (ITU-T), the Consultative Committee for International Telegraph and Telephone (CCITT)
- International Prganization for Standardization (ISO)
- International Engineering Task Force (IETF)
- Electronics Industries Association (EIA)
WAN is designed to:
- Operates in the area of the vast geographical
- Ability to provide a serial connection with low cost and low speed or high cost and high speed such as via the ATM or fiber optic
- Ability to provide full-time connection and part-time
