C1921-ADSL2-M/K9 Use Case
Rural Branch Office Connectivity with C1921-ADSL2-M/K9 Bundle
In a small manufacturing facility located in a rural area lacking fiber or cable, the C1921-ADSL2-M/K9 bundle (HWIC-1ADSL-M, IP Base Lic) delivers ADSL2+ WAN connectivity over existing copper lines. This enables secure VPN tunnels to headquarters and ensures high-availability internet access at a fraction of the cost, boosting productivity and minimizing connectivity expenses.
Automatic WAN Failover for Enterprise Headquarters
An enterprise headquarters uses the Cisco 1921 ADSL2 Anx M Bundle with IP Base Lic to configure a secondary ADSL2+ link via HWIC-1ADSL-M alongside its primary MPLS circuit. When the primary link fails, intelligent failover activates within seconds, maintaining critical application uptime and delivering 99.99% network availability for voice, video and data services.
Rapid MSP Deployment for SMB Internet Services
A managed service provider (MSP) deploys the C1921-ADSL2-M/K9 bundle to provision turnkey internet and VPN services for small and medium-sized business (SMB) clients. Pre-configured hardware with the IP Base license and ADSL2+ interface accelerates installation times by 50%, simplifies centralized management and reduces operational costs for both the MSP and its customers.
