2-Port Serial WAN Interface Card


“2-Port Serial WAN Interface Card” is a network interface card (NIC) that provides two serial ports for connecting to wide area network (WAN) communication links. This interface card is commonly used in networking equipment, such as routers, to enable connectivity to remote sites or devices over serial connections.This type of interface card offers two serial ports. Each port can be used to establish a point-to-point serial connection to another device, such as another router, modem, or terminal server.Serial connections which is for data communication over relatively longer distances. They use serial transmission protocols to send and receive data bit by bit, making them suitable for connections over leased lines, dial-up connections, and other WAN links. Serial connections that can also be used for various WAN connectivity scenarios, including connecting remote offices, branch locations, or equipment in industrial settings.

“2-Port Serial WAN Interface Card” is a network interface card (NIC) that provides two serial ports for connecting to wide area network (WAN) communication links. This interface card is commonly used in networking equipment, such as routers, to enable connectivity to remote sites or devices over serial connections. Here are some key points about the 2-Port Serial WAN Interface Card:

  1. Port Count: This type of interface card offers two serial ports. Each port can be used to establish a point-to-point serial connection to another device, such as another router, modem, or terminal server.
  2. Serial Communication: Serial connections are used for data communication over relatively longer distances. They use serial transmission protocols to send and receive data bit by bit, making them suitable for connections over leased lines, dial-up connections, and other WAN links.
  3. WAN Connectivity: Serial connections can be used for various WAN connectivity scenarios, including connecting remote offices, branch locations, or equipment in industrial settings.
  4. Applications: Serial WAN interface cards are used in networking devices such as routers, access servers, and network appliances. They allow these devices to communicate with other devices over serial links.
  5. Serial Interfaces: Serial interfaces are typically configured with parameters such as baud rate, data bits, parity, and stop bits to establish proper communication settings between connected devices.
  6. Protocols: Serial connections can support various protocols, including HDLC (High-Level Data Link Control), PPP (Point-to-Point Protocol), and Frame Relay, depending on the specific needs of the network.
  7. Expansion: In networking devices that have modular architecture, such as certain routers, you can often add interface cards like the 2-Port Serial WAN Interface Card to expand the available connectivity options.
  8. Legacy and Specialty: While serial connections are considered legacy technology in comparison to modern Ethernet and fiber optic connections, they are still used in various applications where long-distance communication or compatibility with older equipment is required.
