Product Overview

Cisco ® integrated services routers offer a wide variety of WAN connectivity modules to accommodate the range of application needs in customer networks. The Cisco 4-Port ISDN BRI S/T High-Speed WAN Interface Card (HWIC, Figure 1) offers BRI-S/T-port-based WAN connectivity for modular routers deployed in small to medium-sized businesses (SMBs) and enterprise branch offices.

Features

• Four ISDN BRI ports with S/T interface

• Utilizes RJ-45 connectors

Benefits

Integration

The Cisco 4-Port ISDN with S/T interface HWIC provides multifunction dial access server, router, and other capabilities within the Cisco integrated services routers in branch-office environments.

The HWIC is supported on the Cisco 1841, 1941, 2800, 2900, 3800 and 3900 Series Integrated Services 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 4-Port ISDN with S/T interface HWIC upholds Cisco's commitment to providing customers with maximum flexibility and investment protection through modular WICs 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, 1941, 2800, 2900, 3800 and 3900 Series Integrated Services Routers , 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, 2900, 3800 and 3900 Series Integrated Services Routers with the Cisco 4-Port ISDN with S/T 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, 2900, 3800, and 3900 Series Integrated Services 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 4-Port ISDN Network Module

The Cisco 4-Port ISDN with S/T interface HWIC offers all of the features of the Cisco 4-Port ISDN with S/T interface Network Module (NM-4B-S/T) and despite form factor change can be smoothly deployed without any additional training.
