In remote or underserved locations where fiber or MPLS is unavailable, network engineers deploy the Cisco HWIC-ADSLI-B/ST-2-port HWIC w/ 1-port ADSLoISDN and 1-port ISDN BRI-S/T in a Cisco ISR to terminate an ADSL circuit as the primary WAN link and an ISDN BRI channel for automatic failover. This dual-interface design delivers 99.9% uptime, reduces monthly carrier fees by up to 30%, and consolidates WAN management on a single router platform.
In small financial or retail branches requiring guaranteed transaction integrity, IT teams configure the HWIC-ADSLI-B/ST-2-port HWIC w/ 1-port ADSLoISDN and 1-port ISDN BRI-S/T to carry daily data over ADSL and mirror critical POS traffic over an ISDN BRI circuit. This setup ensures real-time failover protection, meets PCI-DSS availability requirements, and maintains encrypted backup channels with sub-second reconvergence.
Retail chains and remote kiosks implement the HWIC-ADSLI-B/ST-2-port HWIC w/ 1-port ADSLoISDN and 1-port ISDN BRI-S/T to aggregate broadband internet over ADSL and dedicated VoIP or telemetry lines over ISDN BRI. The integrated solution reduces hardware footprint, streamlines QoS policy enforcement for voice/data separation, and achieves up to 40% lower TCO by consolidating multiple services on a single Cisco ISR chassis.
