I hope you found this article to be of use and it helps you prepare for your Cisco CCNA certification. Let’s explore the differences and similarities of these protocols. CCNA Certification ... WAN Technologies DSL Cable T1 . What is HDLC? There are several technologies that are employed in the WAN, in this course, however, you are not expected to configure them. Layer 1 protocols describe how to provide electrical, mechanical, operational, and functional connections; Layer 2 protocols define how data is encapsulated; WAN Terms include: The two most popular WAN protocols used on leased lines are High-Level Data-Link Control (HDLC) and Point-to-Point Protocol (PPP). Total Cards. Select the appropriate WAN protocol and service for a specific network requirement. Frame Relay. Typically, Physical Layer protocols that are high speed and transmit across short distances are used in LANs. Cisco CCNA Typical WAN Encapsulation Protocols In order to exchange traffic over a WAN link, the packets must be encapsulated into a Layer 2 frame. HDLC (High-Level Data Link Control) is a layer 2 WAN Encapsulation Protocol that is used on syncronous data links. A clock signal is required for transmitting or receiving synchronous data. ISDN 6. metro Ethernet 7. cable In as much as these technologies have not been discussed in this course, it would be wise to research them and know what they entail.
