The Cisco Multiflex Trunk Voice/WAN Interface Card (MFT) is a highly flexible, converged solution designed to help businesses gracefully migrate from traditional data-only networks and circuit-switched voice or video services to modern, packet-based voice, video, and data networks. Engineered to support multiple integrated applications on one compact card, the MFT family delivers scalable WAN connectivity, seamless voice and video integration, and simplified management within Cisco router ecosystems. By combining data, voice, and video on a single trunk card with integrated DSU/CSU capabilities, this card enables organizations to consolidate infrastructure, streamline deployments, and accelerate time-to-value for unified communications and collaboration initiatives. Whether you’re expanding a regional office, upgrading a campus gateway, or modernizing a service-provider edge, the Multiflex Trunk Card helps you optimize performance, reliability, and total cost of ownership while preserving existing Cisco investments.

  • Unified data, voice, and video support: The MFT is engineered to carry data traffic alongside voice and video streams, enabling a smooth transition from legacy, circuit-based services to modern, packet-switched solutions without rebuilding your entire network. This convergence reduces cabling complexity, minimizes hardware sprawl, and simplifies policy enforcement across your WAN, LAN, and collaboration environments.
  • Port options with scalable density: Available in 1-Port, 2-Port, and 4-Port T1/E1 WIC configurations, the MFT provides flexible density to match diverse site requirements. These options let you incrementally scale capacity as your network grows or as demand shifts from voice-only to multi-service deployments, all while preserving a familiar Cisco hardware footprint.
  • Integrated DSU/CSU for streamlined WAN termination: The built-in DSU/CSU functionality simplifies wide-area network termination and testing, offering reliable circuit termination, diagnostics, and performance monitoring without the need for separate devices. This integrated capability reduces equipment count, lowers maintenance overhead, and supports efficient, error-resistant WAN connections for branch offices and data centers alike.
  • Packet-voice readiness and quality of service: The Multiflex Trunk card is designed to support packetized voice and video with Cisco QoS and traffic shaping features, ensuring predictable latency, jitter control, and bandwidth allocation. This makes it ideal for voice gateways, video conferencing, voice-over-IP, and real-time collaboration tasks where timing and prioritization matter most.
  • End-to-end Cisco ecosystem compatibility: Built to integrate seamlessly with Cisco routers and IOS-based management, the MFT aligns with Cisco security policies, routing, and unified communications solutions. By leveraging familiar configuration workflows, administrators can deploy converged services quickly, maintain consistent policy enforcement, and achieve end-to-end visibility across data, voice, and video channels.

Technical Details of Cisco Multiflex Trunk Voice/WAN Interface Card

  • Data Solutions: 1-, 2-, and 4-Port T1/E1 WIC with Integrated DSU/CSU, enabling flexible trunking for diverse branch, campus, and data-center use cases.
  • Converged capabilities: Supports integrated data, voice, and video applications on a single WIC, reducing hardware requirements and enabling smoother migration paths to packet-based services.
  • Integrated DSU/CSU: Built-in digital service unit/data service unit for WAN connectivity, simplifying installation and maintenance while delivering reliable circuit termination and diagnostics.
  • Modular flexibility: Part of the Cisco Multiflex Trunk family, allowing administrators to tailor capacity and features to match evolving network demands without changing the core router platform.
  • Cisco ecosystem support: Fully compatible with Cisco routers and IOS management, with support for Cisco QoS, security features, and Unified Communications integration to deliver cohesive performance across the network.

how to install Cisco Multiflex Trunk Voice/WAN Interface Card

  • Prepare the equipment: Power down the Cisco router or ISR, disconnect from power, and discharge any static electricity by touching a grounded metal surface.
  • Identify the correct WIC slot: Locate the appropriate WIC slot on your Cisco device that supports Multiflex Trunk cards and verify clearance for the 1-Port, 2-Port, or 4-Port configuration.
  • Insert the MFT card: Gently align the card with the slot and insert it until it seats firmly and the locking mechanism engages. Do not force the card and ensure there is no resistance from adjacent modules.
  • Connect T1/E1 lines and DSU/CSU: Attach your T1 or E1 cables to the WIC’s ports and verify DSU/CSU interfaces are correctly configured for your WAN topology. Prepare any required loopbacks or test patterns for initial validation.
  • Power on and configure: Reconnect power, boot the device, and enter IOS configuration. Enable the new interface, assign IPs, and implement QoS, VLANs, and voice routing policies appropriate to your deployment. Validate connectivity with basic ping tests and, for voice, check jitter, latency, and MOS where applicable.

Frequently asked questions

  • Q: What is the Cisco Multiflex Trunk Voice/WAN Interface Card?

    A: It is a versatile family of trunk interface cards designed to carry data, voice, and video traffic on Cisco routers. With built-in DSU/CSU, it supports both WAN termination and convergence, enabling organizations to migrate from circuit-switched services to packet-based, Unified Communications solutions.

  • Q: What port configurations are available?

    A: The MFT comes in 1-Port, 2-Port, and 4-Port T1/E1 WIC configurations, offering scalable density to match site-specific bandwidth and service requirements while preserving compatibility with existing Cisco platform investments.

  • Q: Does the card include DSU/CSU functionality?

    A: Yes. Integrated DSU/CSU simplifies WAN termination and diagnostics, reducing the need for separate devices and contributing to a leaner, more maintainable network edge.

  • Q: Is it compatible with Cisco IOS QoS and security features?

    A: Absolutely. The Multiflex Trunk card is designed to work with Cisco’s IOS-based management, QoS policies, and security frameworks to ensure reliable voice and video performance alongside data traffic.

  • Q: What are typical use cases for the MFT?

    A: Common deployments include branch and campus WAN convergence, gradual migration from circuit-switched voice/video to packet-based communications, and scalable edge solutions for service-provider or enterprise networks requiring flexible trunking and unified communications integration.

The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.

Good quality dog ball for playing fetch
Size: Medium
My dog and family love these chuck it balls to play fetch with our dog. They are durable and fun. They squeak which is added fun for any dog! Regular tennis balls my dog chews apart and they get pretty gross after playing and being left outside. These can be easily washed off and cleaned. These balls last! Would recommend to anyone with a dog and would purchase again.
