CISCO2801-ADSL2/K9 Use Case
Secure Retail Branch WAN over ADSL2 with Cisco 2801
A national retail chain deploys the Cisco2801-ADSL2/K9 bundle with HWIC-1ADSL and SP Svcs on every small-format store. The router terminates a managed ADSL2 line (128F/384D) and establishes VRF-based segmentation for PoS terminals, VoIP handsets, and CCTV streams. An IPSec tunnel to HQ over the SP-provisioned ADSL link ensures end-to-end encryption. Benefit: 99.9% WAN availability, 50% reduction in MPLS costs and PCI DSS-compliant segmentation without appliance sprawl.
Rural Telemedicine Site-to-Site VPN via ADSL2
A network of rural clinics uses the Cisco2801-ADSL2/K9 with HWIC-1ADSL and SP Svcs to connect remote exam rooms to a central hospital. The 128Kbps uplink/384Kbps downlink ADSL2 circuit carries VoIP, high-res medical imaging and EHR traffic over an IPSec VPN. QoS policies on the 2801 ensure voice and imaging get priority. Benefit: Real-time diagnostics, HIPAA-grade encryption, and 30% faster remote consultations without upgrading fiber infrastructure.
SMB Hybrid WAN with ADSL2 Backup and QoS
An SMB head office running critical ERP and VoIP services on MPLS adds the Cisco2801-ADSL2/K9 plus HWIC-1ADSL and SP-managed ADSL2 (128F/384D) as a secondary link. The 2801 automatically detects MPLS failures and routes traffic over ADSL2. Built-in QoS enforces Class-Based Weighted Fair Queuing, guaranteeing voice quality and prioritizing ERP transactions on the backup link. Benefit: Seamless failover, 24/7 uptime, and a 40% improvement in voice MOS scores at minimal additional CAPEX.
