VWIC2-2MFT-G703 Use Case
Global Call Center TDM Trunking with Cisco VWIC2-2MFT-G703-2-Port Card
A multinational contact center deploys the VWIC2-2MFT-G703-2-Port 2nd Gen Multiflex Trunk Voice/WAN Interface Card on Cisco ISR routers to terminate high-density G.703 digital trunks from regional PSTN carriers. This use case delivers up to 120 concurrent voice channels per card, delivering carrier-grade voice quality, reduced latency and centralized trunk management. Outcome: scalable, reliable call routing, 30% lower per-call costs and consistent QoS across geographies.
Branch Office Legacy PBX Integration over MPLS WAN
A retail chain integrates legacy TDM PBXs at 50 branches into its MPLS backbone using the VWIC2-2MFT-G703-2-Port card. Each branch router carries both voice (G.703) and data over a single WAN link, eliminating separate T1/E1 wiring. Benefit: 40% reduction in cabling and circuit fees, unified network operations and preserved investment in existing PBX infrastructure.
High-Availability Voice Network for Financial Services
A global bank builds an active/standby voice trunk architecture using both ports of the VWIC2-2MFT-G703-2-Port card on dual ISR platforms. G.703 trunks connect mission-critical trading floors to headquarters, with automatic failover under 50 ms. Result: 99.999% uptime, seamless voice continuity for trading operations and compliance with stringent regulatory SLAs.
