The Cisco 1-Port ISDN BRI U High-Speed WAN Interface Card (HWIC) is designed to provide reliable WAN connectivity for modular routers, specifically catering to the needs of small to medium-sized businesses and enterprise branch offices. By integrating this card into Cisco’s router platforms, organizations can achieve a more streamlined network infrastructure that supports essential data, security, and voice services within a single, cohesive system.

This solution emphasizes flexibility and investment protection, allowing businesses to adapt their network configurations as their bandwidth requirements or service provider offerings evolve. Because the card is compatible with a wide range of Cisco Integrated Services Routers, it helps reduce the complexity of managing multiple hardware components, ultimately leading to more efficient network operations and simplified deployment processes.

Product overview

The primary product discussed is the Cisco 1-Port ISDN BRI U High-Speed WAN Interface Card (HWIC-1B-U). This module provides a single ISDN BRI port with a built-in NT1 and utilizes an RJ-49C connector for connectivity. It is engineered to be a direct, high-performance upgrade for users familiar with the previous Cisco 1-Port ISDN WIC, ensuring that deployment can be handled smoothly without the need for additional training.

The card is supported across a broad spectrum of Cisco Integrated Services Routers, including the 1841, 1941, 2800, 2900, 3800, and 3900 series. By consolidating WAN access and voice functions—such as IP telephony and automated attendants—into these platforms, the HWIC enables a converged environment. This integration not only saves physical space but also enhances overall system reliability by reducing the number of individual devices, power supplies, and cables required in the network rack.

Features and benefits

Integrated Connectivity: Features one ISDN BRI port with a U interface and a built-in NT1, using a standard RJ-49C connector.
Operational Efficiency: Simplifies management through remote configuration, monitoring, and troubleshooting via Cisco IOS Software CLI and SNMP.
Platform Flexibility: Supports redeployment across various Cisco router series (1841, 1941, 2800, 2900, 3800, and 3900), which helps reduce inventory stocking units.
Enhanced Reliability: Minimizes potential points of failure by reducing the total number of components and cables in the network setup.
Converged Services: Enables the deployment of advanced voice services, such as Cisco Communications Manager Express and SRST, when used with compatible routers and digital signal processors.
Seamless Transition: Offers full feature parity with the legacy Cisco 1-Port ISDN WIC, allowing for an easy upgrade path for existing network infrastructures.

2014-01-07 :Updated

Cisco integrated services routers offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The Cisco 1-Port BRI U High-Speed WAN Interface Card (HWIC, Figure 1) offers BRI-U-based WAN connectivity for modular routers deployed in small to medium-sized businesses (SMBs) and enterprise branch offices.

Features

• One ISDN BRI port with U interface (built-in NT1)

• Utilizes an RJ-49C connector

Benefits

Integration

The Cisco 1-Port HWIC-1B-U offers a single ISDN BRI port with U interface. The ISDN HWIC is supported on the Cisco 1841, 1941, 2800, 2900, 3800 and 3900 Series Routers. It provides a cost-effective ISDN routing solution with the following benefits of integration:

• Fewer devices and cables to deploy and manage

• Remote and local configuration, monitoring, and troubleshooting with the Cisco IOS Software command-line interface (CLI) and Simple Network Management Protocol (SNMP)

• Single-vendor support

• Enhanced reliability

• Physical space savings

Flexibility and Investment Protection

The Cisco 1-Port ISDN U interface HWIC upholds Cisco's commitment to providing customers with maximum flexibility and investment protection through modular HWICs that are supported on award-winning router platforms. When WAN bandwidth requirements or service provider pricing changes, users can easily change WAN services either by changing the software configuration or replacing the HWIC. Because the same card can be used on Cisco 1841, 2800, and 3800 Series router platforms, the number of stocking units can be reduced, and the HWIC can be redeployed from one platform to another.

Enhanced Reliability

An integrated solution has fewer components and hence, fewer points of failure (for example, one less power supply and fewer cables). This leads to enhanced reliability.

Converged Platform for SMB and Enterprise Branch Applications

The Cisco 1841, 1941, 2800, 3800, and 3900 Series Integrated Services Routers with the Cisco 1-Port ISDN U interface HWIC provide customers with a choice of converged platforms that offer best-of-class data, security, WAN access, and voice services in a single system. The Cisco 2800 and 3800 Series routers and the Cisco 2900 and 3900 Series Routers embed voice functions directly inside the router, enabling customers to deploy voice services by installing digital signal processors (DSPs) and advanced integration modules (AIMs) for IP telephony conferencing, voice gateways, and Cisco Unity Express voicemail and automated attendant. For call processing, customers can enable the Cisco Communications Manager Express solution as part of Cisco IOS Software and reconfigure the same software to support Cisco Survivable Remote Site Telephony (SRST) for centralized call processing with Cisco Communications Manager. Such an integrated solution enables rapid service deployment, increases efficiency of network operations, and provides opportunities to protect, grow, and optimize your business.

Shared Features with Cisco 1-Port ISDN WIC

The Cisco 1-Port ISDN U interface HWIC offers all of the features of the Cisco 1-Port ISDN U interface WIC (WIC-1B-U-V2) and can be smoothly deployed without any additional training.
