HWIC-4B-S/T

Overview Of HWIC-4B-S/T

The HWIC-4B-S/T is a High-Speed WAN Interface Card (HWIC) developed by Cisco to be integrated into Cisco routers. This particular HWIC model features four ports, each supporting Integrated Services Digital Network Basic Rate Interface (ISDN BRI) connectivity. ISDN BRI is a digital communication technology that provides two 64 Kbps bearer (B) channels and one 16 Kbps signaling (D) channel over a single twisted-pair copper wire. Each port on the HWIC-4B-S/T allows for the connection of ISDN BRI devices, such as telephones, fax machines, or other networking equipment, providing versatile and reliable communication options. By integrating the HWIC-4B-S/T into Cisco routers, users can establish ISDN connections for various applications, including voice, data, and video transmission. This card enhances the router's capabilities by enabling high-speed and efficient communication over ISDN networks, contributing to seamless connectivity for diverse networking requirements.
