For Cisco routers and switches, an important element cannot be forgotten is different kinds of Cisco modules and cards, for example, the Cisco integrated Cable high-speed WAN interface cards (HWICs) provide lower total cost of ownership, advanced quality-of-service (QoS) enforcement, and advanced monitoring and load-balancing capabilities for customers by optionally integrating a DOCSIS 2.0-based cable modem within a Cisco Integrated Services Router (ISR) or Cisco IAD2430 Series Integrated Access Device. Additionally, the new Cisco Cable HWICs greatly expand the portfolio of managed business-class cable services cable operators can offer to their small and medium sized business (SMB) and enterprise customers. These cable HWICs, combined with the Cisco 2800 and 3800 Series Integrated Services Routers; Cisco 1841 and 1941 Integrated Services Routers and Cisco IAD2430 Series provide high-speed digital data transmission between customer premises equipment (CPE) and a central office. This enables cable service providers and resellers to offer additional services by supporting features for business-class security, voice integration, differentiated classes of service (CoS), and managed network access with Cisco IOS Software. These value-added features, along with the manageability and reliability of Cisco IOS Software technology, provide the mission-critical networking that businesses require. Features and Benefits of Cisco Cable HWIC Module Standards Based: • The Cable HWICs are designed to comply with DOCSIS 2.0 standards and integrate transparently within existing cable operator networks. • HWIC-CABLE-D-2 is designed to comply with DOCSIS 2.0. • HWIC-CABLE-E/J-2 is designed to comply with the J-DOCSIS and Euro-DOCSIS 2.0 standards. (Note: J-DOCSIS downstream center frequency is limited to 90-860MHz.) • The Cable HWIC is designed to work in PacketCable™ Multimedia networks and supports up to 15 secondary service flows. Independent Software Image: The Cisco Cable HWIC runs its own firmware image and can be upgraded independently of the host router's Cisco IOS Software by the cable modem termination system (CMTS). Protected Cable Modem Configuration: The Cisco Cable HWIC configuration can only be changed by the cable operator using a CMTS. Maximum Availability: • The Cisco Cable HWIC can be restarted independently of Cisco IOS Software by the CMTS or by the end user. • The Cisco router with the integrated cable modem can monitor the cable modem state and automatically reroute traffic to an alternate interface in the case of a WAN failure. • Replaces the external RJ-45 cable when using an external cable modem with a highly available internal connection. • Integration limits the opportunity/potential for opportunistic theft of the cable modem or accidental disconnection. Tips: More details of Cisco Cable High-Speed WAN Interface Cards such as Cisco IOS Software Support, Ease of Management and Deployment, Hardware Specifications, etc. you can visit official cisco.com. The Cisco Cable HWICs enable a higher level of physical and logical security, provide advanced QoS for IP Communications, easy expandability, higher availability, and simplified management for SMBs and enterprise branch offices. By integrating the Cable HWIC into existing or new Cisco IOS Software-based routers, the Cisco Cable HWICs can help businesses of all sizes avoid expensive private circuit upgrades and allow cable operators to reach a broader set of customers and provide increasing levels of advanced managed services in a cost-effective manner.
