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

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.

A Spa-tacular Addition to My Bathroom Oasis!
Size: 24in-Shelve
Perfect Statement Piece for My Spa-Like Bathroom! I know this review is super delayed~I’ve been living out of the country, and only just got around to installing this beautiful shelving unit. But wow, it was worth the wait! I hung it in my bathroom above the jacuzzi tub where I have vaulted ceilings and a skylight, and it fits perfectly. It adds the perfect industrial-chic touch I was looking for. I use it to store all my bath oils, salts, and candles, and it’s transformed the space into a relaxing, elevated sanctuary. The quality is fantastic and it was easy to install. Honestly, it looks like something out of a spa catalog. Highly recommend for anyone looking to upgrade their bathroom with both function and style!

Great deal for the money, look sharp, and very sturdy
Size: 32in-Shelves, Size: 32in-Shelves
I was looking to create pipe shelves in our living room. After spending some time researching prices for pipe and wood, I determined that I would save money by buying a couple sets of these shelves. When the shelves came in, I was happy to learn that they were indeed good quality and easy to assemble. They come with mounting hardware, but I’d recommend better mounts for the walls than the ones supplied. Overall, I love the look of these shelves. The wood is described as reclaimed, but it’s pretty much cheap, light wood with a stain. They still look good and are sturdy. The pipes has some silver paint brushed on them to give them a distressed look. I thought it was actually a little cheesy looking, but I happened to have iron-colored spray paint, so I just respirated them.

Looks good but the wall anchors is TRASH!
Size: 3-tier shelves, Size: 3-tier shelves
The product is heavy and sturdy once you get it up completely. The issue I have is with the instructions... 1. The 5/16 drill bit is recommends is WAY TO BIG. The Anchors it comes with will slip right through. The screws that is comes with are WAY TO SMALL for the weight. I recommend getting better ones from the hardware store and painting the screws black for better aesthetics. 2. The instructions say to put it together first then hang it on the wall. That is great so you can see where you want to place it and because it is actually bigger than it looks, but you will need to de-assemble it from the bottom shelf down after you mark where you want to place it, then put that part on the wall, then reassemble it from there, securing the top part to the wall last. The instructions sucked but that is what worked best for me. Another thing is when you first assembling it, you will notice that you will have to unscrew it a bit so the pipes can fast the correct way. This will make it feel flimsy, but it will tighten up when you secure it to the wall. Also, like some people said in previous reviews, some of the black paint did peel off the pipes, not to much for me but it was noticeable if you look at it hard enough.
