EM-4BRI-NT/TE Use Case
Multi-Site Branch Integration with ISDN BRI for Retail Chains
A nationwide retail chain deploys Cisco ISR routers fitted with the EM-4BRI-NT/TE 4-port voice/fax expansion module in NT mode at each outlet. This setup directly terminates local ISDN BRI lines, aggregates voice calls, and transports store-level fax traffic over the MPLS backbone. Benefit: Centralized call management, 40% reduction in leased-line costs, and guaranteed high-quality voice/fax service to headquarters.
Legacy Fax and Voice Consolidation in Financial Services
A regional bank modernizes four branch offices by installing Cisco routers with the EM-4BRI-NT/TE module in TE mode. The solution converts legacy analog fax machines and POTS lines into digital ISDN BRI channels, then routes them via SIP trunks to the corporate data center. Benefit: 50% lower telephony expenses, streamlined digital-fax workflows, and full compliance with data-security regulations.
Secure Emergency Voice/Fax Gateway for Utility Remote Sites
An electric utility implements the EM-4BRI-NT/TE 4-port voice/fax expansion module in NT/TE mode on remote substation Cisco routers. In case of primary IP network failures, substations automatically switch to ISDN BRI for SCADA alarm voice calls and faxed status reports. Benefit: Uninterrupted emergency communications, 24/7 operational resilience, and adherence to industry uptime mandates.
