Corporations, campuses, and even cities often have an Internet network for administrative tasks and general usage. WAN interface cards allow routers to share data over a Wide Area Network (WAN) and act as a gateway for other devices to access the network. Besides computers, even
, and fax machines rely on a WAN interface card to communicate with each other. This interface card, or WIC, comes in a few variations, with each type serving a specific function. By knowing the types of WICs available, buying the correct interface card for any network protocol is an easy task.
Modes Supported by the WAN Interface Card
WAN interface cards
supports synchronous (STM) and asynchronous (ATM) data transfer modes. In a STM, the sender and receiver use the same clock signal, whereas in an ATM, the receiver synchronises its timing to the sender's signal before data transfer. ATM is cheaper and faster to set up than STM. However, it has a lower throughput, meaning that it transmits less useful data than STM, and therefore has a slower transfer rate.
How to Buy a WAN Interface Card
To purchase the right
WAN interface card
, run a simple search on
. Specify the type or model of the card you want and then choose from the product listing. Pay attention to the condition, price, and type of WIC before selecting one. Read all the available information of a particular card. WAN interface cards enable users to connect to a wide area network, and interact with each other. This is especially important for businesses since the constant connectivity enables members to communicate and share information. The right type of WIC ensures fast and stable network connections.
