The Cisco TelePresence® ISDN Link is a compact, purpose-built appliance designed to bridge Cisco TelePresence endpoints with ISDN networks and external data networks. Specifically engineered to support Cisco TelePresence EX, MX, SX, and C Series endpoints, this device provides direct, reliable connectivity to ISDN lines or external networks (V.35) for individual telepresence units. It simplifies room-based deployments by delivering a dedicated interface that minimizes setup complexity and maximizes the value of your immersive collaboration investments. With its streamlined form factor and Cisco’s trusted engineering, the ISDN Interface Uni enables seamless, high-quality video communications in conference rooms, executive offices, training spaces, and huddle rooms, all while fitting neatly into standard AV racks or cabinet layouts. Whether you need a point-to-point connection or a gateway-like bridge to remote sites, this appliance is designed to make integration straightforward, scalable, and robust against the changing demands of modern teams working across internal networks and service providers.

  • Direct, plug-and-play connectivity for TelePresence endpoints. The ISDN Link provides a dedicated interface that connects Cisco TelePresence EX, MX, SX, and C Series endpoints to ISDN networks or external V.35 networks with minimal configuration. This direct path reduces latency, preserves video fidelity, and simplifies troubleshooting by eliminating multiple intermediary devices between the endpoint and the transport network.
  • Flexible ISDN and external network support. By supporting ISDN access and external network connectivity through V.35 interfaces, the unit enables versatile deployment scenarios. Teams can establish reliable, low-latency connections for in-room collaboration, enabling high-quality video and audio during multipoint calls, remote demos, or secure point-to-point sessions with remote sites and service providers.
  • Compact, room-friendly design for diverse environments. The ISDN Interface Uni is engineered as a compact appliance that fits neatly in in-room cabinets or on a shelf, preserving valuable rack space for other collaboration gear. Its unobtrusive footprint makes it suitable for executive suites, training rooms, boardrooms, and shared collaboration spaces where aesthetics and space efficiency matter as much as performance.
  • Compatibility and integration with Cisco TelePresence ecosystems. Built to align with Cisco’s TelePresence portfolio, this interface ensures smooth interoperability with existing Cisco endpoints and management tools. Organizations can leverage familiar provisioning workflows, policy-based QoS, and centralized monitoring to streamline operations, reduce downtime, and accelerate new deployments across campuses or facilities.
  • Improved reliability, QoS, and call quality in mixed networks. By delivering a dedicated ISDN/V.35 path for each endpoint, the device helps preserve call quality even in environments with mixed network types. The interface is designed to sustain consistent video performance, support secure connections, and minimize jitter and packet loss, which translates into clearer conversations, crisper visuals, and a more productive collaboration experience for all participants.

Technical Details of Cisco ISDN Interface Uni

  • Interfaces: ISDN and external network connectivity via V.35, designed to connect directly to Cisco TelePresence endpoints.
  • Supported endpoints: Cisco TelePresence EX, MX, SX, and C Series endpoints, with optimized operation when paired with these systems.
  • Form factor: Compact appliance suitable for in-room installation, rack-mountable or shelf-ready in typical collaboration environments.
  • Connectivity goals: Provides a dedicated bridge between in-room endpoints and external networks to support reliable, high-quality video sessions.
  • Management alignment: Designed to integrate with Cisco TelePresence management and provisioning workflows for consistent configuration, monitoring, and updates.
  • Operational focus: Emphasizes straightforward setup, predictable performance, and compatibility with standard enterprise networking practices in collaboration deployments.

How to install Cisco ISDN Interface Uni

  • Plan your deployment by identifying the appropriate in-room TelePresence endpoint, ISDN line, and external V.35 network path. Confirm that your environment meets the general requirements for a clean installation, including appropriate cabling, labeling, and space for the appliance.
  • Unpack the ISDN Interface Uni and verify that all components are present. Inspect ports and connectors to ensure there is no damage and that cables intended for ISDN and V.35 networks are ready for connection.
  • Connect the ISDN line to the ISDN interface and attach the external network path (V.35) as required. Ensure that the cabling complies with your organizational standards for telecommunications and external network connections, including proper shielding and grounding where applicable.
  • Link the interface to the Cisco TelePresence endpoint(s) in your room. This creates a direct, dedicated pathway for ISDN and external network traffic, enabling the endpoint to access the appropriate networks for call setup, signaling, and media transport.
  • Power on the device and perform initial provisioning using your Cisco TelePresence management tools. Validate connectivity to the endpoint, confirm call setup capabilities, and run a basic test call to verify video and audio quality across the ISDN/V.35 path.
  • Fine-tune network settings as needed, applying QoS policies, routing preferences, and security controls to ensure optimal performance in your environment. Document the configuration for future maintenance and potential scale-out deployments.
  • Document the deployment, including endpoint pairings, network paths, and any special configurations. Establish a monitoring routine to track reliability, call quality, and usage trends to support ongoing optimization and troubleshooting.

My second pair and what they look like after 2 years
Size: 10.5, Color: New Black05, Size: 10.5, Color: New Black05
I wanted to write a review on these shoes. This is my second purchase. I bought the first pair 2 years ago and the bottoms started wearing out, after all it was 2 years. I read reviews saying that they did not hold up well. My pictures show before and after. The reason I purchased again is because I am impressed with the quality and comfort for the money.

Comfortable at First, But Did Not Last Long
Size: 9.5, Color: Cs05 White
I used these Feethit men’s slip on running shoes for about six months, and my experience was a bit mixed. Starting with the positives, they are pretty comfortable right out of the box. They are lightweight and easy to slip on, which makes them great for quick trips or casual everyday wear. The fit was true to size for me, maybe even a little on the loose side, which I did not mind for a relaxed feel. However, the durability just was not there. After about six months, I started to notice wear and tear, and eventually I got a tear in the sole right under my heel. That made them really uncomfortable to walk in, especially for longer periods. Once that happened, it was basically game over for using them regularly. Because of that, I would not recommend these for heavy use, workouts, or long days on your feet. They seem better suited for light, occasional wear rather than something you rely on daily. Overall, they are comfortable and easy to wear at first, but they do not hold up over time. If you are looking for something long lasting, you may want to look at other options.

Won’t Fit No Matter What
Size: 9.5, Color: Cs05 White, Size: 9.5, Color: Cs05 White
These shoes don’t stretch so I was unable to get my foot in the shoe. They are my size, but the opening has no stretch so you can’t get your foot in the shoe. I tried several different ways and then realized even though the shoe is the correct size, the opening was too small. They made the opening for the shoe probably the same size on all shoes, so unless you have kids feet you won’t even be able to slide them on. I’ve never had a shoe I couldn’t get on. I’ve worn Sketchers no problem. This is design flaw and I highly recommend you don’t buy!
