HWIC-1B-U Use Case
Remote Branch Office WAN Connectivity with ISDN BRI Backup
A mid-market retailer deploys the HWIC-1B-U-1-Port ISDN BRI U High-Speed WAN Interface Card in Cisco 2900 Series routers at 50 remote outlets. Primary IP VPN over DSL delivers daily transaction data; the ISDN BRI interface provides automatic dial-up failover on link loss. Outcome: 99.9% uptime SLA, seamless order processing, and centralized network management without additional hardware.
Legacy PBX Integration for Voice and Data Convergence
An insurance firm integrates its ISDN PBX system with a unified Cisco router using the HWIC-1B-U-1-Port ISDN BRI U High-Speed WAN Interface Card. The card bridges legacy voice channels to VoIP trunks, enabling centralized SIP routing and QoS enforcement across MPLS links. Benefit: reduced capital expenditure, streamlined voice provisioning, and consistent call quality under a single network infrastructure.
Secure Emergency IP Fallback for Critical Infrastructure
A government utility operator configures the HWIC-1B-U-1-Port ISDN BRI U High-Speed WAN Interface Card on Cisco ISR routers at SCADA sites. In the event of primary fiber or microwave failure, the card establishes an encrypted ISDN BRI tunnel to the control center. Result: guaranteed emergency connectivity, rapid failover in under 30 seconds, and compliance with regulatory uptime mandates.
