In remote branch offices lacking fiber, IT teams install the Cisco HWIC-ADSL-B/ST-2-port HWIC w/ 1-port ADSLoPOTS and 1-port ISDN BRI-S/T in ISR routers to aggregate ADSL2+ and ISDN BRI links. Benefit: Delivers up to 15 Mbps combined throughput with seamless failover, ensuring continuous connectivity, reduced downtime, and optimized cost per Mbps for critical business applications.
A national retail chain equips each store’s Cisco ISR with the HWIC-ADSL-B/ST-2-port HWIC w/ ADSLoPOTS & ISDN BRI-S/T to run parallel ADSL2+ and ISDN backup links. Benefit: Provides automatic link failover and load balancing for point-of-sale transactions and inventory systems, enhancing uptime, transactional security, and customer experience during peak hours.
Regional banks integrate the Cisco HWIC-ADSL-B/ST-2-port HWIC w/ 1-port ADSLoPOTS and 1-port ISDN BRI-S/T into their ISR routers to deploy a dedicated backup line over ISDN when MPLS fails. Benefit: Ensures mission-critical connectivity for secure financial transactions, meets regulatory uptime SLAs, and mitigates risk by enabling sub-second failover and continuous encrypted data exchange.
