Scenario: A global enterprise deploys dual T1/E1 circuits to each remote office for MPLS backhaul. By inserting the VWIC-2T1/E1-RAN-2-Port RJ-48 WIC into Cisco ISR routers, the branch automatically fails over to the secondary line within milliseconds when the primary link degrades. Benefit: Ensures uninterrupted business applications, maximizes WAN uptime (>99.999%), and reduces SLA penalties by delivering zero-touch protection switching and real-time link health monitoring.
Scenario: A large contact center relies on redundant T1 trunks to handle inbound toll-free traffic. Integrating the VWIC-2T1/E1-RAN WIC with RAN/ITP/SLT support enables automatic trunk switchover on line failure, seamless SS7 signaling, and synchronized channel state across both RJ-48 ports. Benefit: Maintains 24×7 voice-network reliability, prevents dropped calls during peak hours, and optimizes customer satisfaction by guaranteeing continuous dial-tone availability.
Scenario: A regional electric utility uses Cisco ISR routers with dual T1/E1 links to connect remote substation RTUs over private data circuits. The VWIC-2T1/E1-RAN-2-Port module provides in-service switching, transparent clock synchronization (SLT), and link integrity testing (ITP) to ensure critical telemetry data always routes over the healthiest path. Benefit: Delivers deterministic SCADA performance, minimizes outage risk for control traffic, and supports regulatory compliance through continuous link-state logging and automated failover.

Excellent performance! The VWIC-2T1/E1-RAN integrates smoothly and maintains stable WAN connections across all devices.
The Cisco VWIC-2T1/E1-RAN is a 2-port RJ-48 WAN interface card (WIC) that provides T1/E1 connectivity with protection switching for RAN, ITP and SLT applications in Cisco routers.
This WIC supports two RJ-48 interfaces for T1 or E1 circuits and offers in-service protection switching for seamless network failover.
Protection switching automatically reroutes traffic from a failed T1/E1 port to the backup port within 50 ms, ensuring continuous service availability.
It supports full T1 (1.544 Mbps) and E1 (2.048 Mbps) data rates on each of the two ports simultaneously.
The VWIC-2T1/E1-RAN is compatible with Cisco Integrated Services Routers (ISR) G2, ASR 1000 series and certain 4000 series routers—verify your platform's data sheet for specifics.
Installation requires an open WIC slot, the correct IOS image with T1/E1 support and configuration commands for channelized T1/E1 and protection groups.
Yes. You can configure each port as an independent T1 or E1 circuit, or as an active/standby pair for failover protection.
Yes. The card supports various framing formats (D4, ESF for T1; CCITT, G.704 for E1) and clocking options (internal, loopback, line).
The card offers built-in local and remote loopback tests, alarm statistics, and performance monitoring via Cisco IOS performance commands.
Common use cases include enterprise branch connectivity, PBX trunking, leased-line redundancy and mission-critical data backup links.
Use Cisco IOS commands: ‘interface serial . . . ’, ‘service instance protection’, and ‘protection group’ settings to define active and standby ports.
The WIC consumes approximately 3 W, operates between 0°C to 45°C and meets standard Cisco environmental and EMI compliance for enterprise deployments.
Run ‘show controllers serial 0/0’ and ‘show service-instance protection’ to view port status, protection state and diagnostic alarms.
Ensure your router runs a Cisco IOS image version that explicitly lists VWIC-2T1/E1-RAN support—no separate firmware is needed.
Cisco provides a limited lifetime warranty for hardware defects, plus optional SMARTnet® service for 24×7 technical support and OS updates.
