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.

Magnet is super strong but hooks are not adjustable
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
I ordered this set of Mutuactor magnetic hooks because I was tired of thinking I had things organized and then finding previously hung magnets have slid down the wall. It was a first for me to have to assemble a magnetic hook. This was made slightly more difficult by requiring a wrench. So many items these days arrive with a disposable little hex wrench or whatever is needed for assembly. Not in this case. Maybe the manufacturer assumes if you are spending $15 per magnet to hang your tools you have a wrench handy. Anyway, I got my wrench and found no instructions. I know from life that the order is bolt-washer-lock washer-nut. The next question arose when I found one bolt and several holes... hmmmm. It looks like they wanted to provide the option to screw the hooks directly to the wall. I am not sure the average person would pay that price just for a hook, though. I chose a hole and it seems to be the right one. The good news is I was quickly in business. Soon one magnet was snatched by my husband for his rolling tool cart. He hung his (very heavy) Sawzall and the magnet never moved. He liked the rubber coating that protects his tools. I chose to take advantage of the amazing grip of this thing to hang my most used (and also very heavy) all-clad pan from the side of my fridge. The refrigerator had some sort of glossy powder coat and magnets hold well if you try to pull them straight off but end up sliding down anyway. This is where I came to appreciate the rubber shoe of this magnet. It protects my fridge but I think it plays an essential part in the grip strength of the magnet. I can not slide it around - I need to use two hands to pull it off then place it in another position. To give a magnet strength example I had one magnetic hook on my desk as I was writing this review. My nearby desk-size scotch tape dispenser came sliding over and the magnet grabbed it. I was able to lift the tape dispense just by the magnet grabbing the little piece of metal serrated teeth that cut the tape. There is no other metal in my dispenser. That's it! In summary, four stars because it REALLY grips and holds a lot of weight. Minus a star because I do think they are a little expensive, they required assembly without tools or instructions, and the hooks themselves are not adjustable. I have some similar magnetic hooks and you can move the two prongs apart or together depending on what your tool size is. These prongs are strong and firm and are not moving and this cuts down of the number of uses a little bit.

Develop some quality, worth-while hangups!
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
Organization is key for any shop space. This goes double for smaller shops. If you look around and DON'T see something that could benefit from getting off the floor and onto a peg or hook, I applaud you! For the rest of us, where can we get started? Here you go. These hooks come two in a package. The quality of these are easy to see. The powder coating is very nice as powder coating is more durable than paint. The orange plastic coating on the hooks feels thick and durable. Assembly is easy. There's a threaded post sticking out of the black rubber coated magnet "puck" that you insert into a opening on the hook and secure with washers and a nut. I like that they included both a washer and locking washer. If it matters, I always stack the fastener in the following order: washer, locking washer, then nut. Using a 14mm socket, I was done in no time. How's much will these hooks hold? The magnetic power on these hooks feels substantial. When I slowly approached the side of my metal toolbox, the magnet made an audible snap when it magnetized to the side. It felt strong! The bend at the base of the hook added stability pressing against the toolbox but didn't mark the surface since it was covered by plastic. It held my heavy 50a extension cable and the other hook held both my 25' and 50' pressure washer hoses. Neither moved at all and felt very secure. Whether your shop is your garage or basement, making the most of your space makes a difference and these can help. These are very strong and hold items safely. I'm very happy having these around and will be getting more. If you have a metal surface that you can attach hooks, give these a try. It's a quality solution!

Awesome product!!!
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
Wow when they describe these magnets as “super string” they are not joking! Magnets are so strong you must be careful when placing them on your metal cabinet, lest it pinch your finger when the magnet grabs the metal! This is an awesome product. The hooks have a hole in their base that fits over a threaded post / bolt coming out of the center of the magnet and the kit comes with two washers, lock washers, and bolts to attach the hooks to the magnets. Takes about one minute per magnet to assemble. Once on the wall they feel like they will hold a lot of weight though I did not try to test the upper limit. No problem at all holding yard tools and the like. The hooks or arms have a nice rubberized coating and extend about 4.5” out from the wall. At $15 each these seemed a little pricy but wow what a great solution for hanging things on metal walls. They work so well I will be buying more of these! I actually have some other similar very strong round magnets made for a similar purpose … but they do not have the “built-in” hooks like these do and it makes a big difference for the usefulness! Considering all of that I think they are a great value. Item reviewed: MUTUACTOR Updated Super Strong Magnetic Hooks,40lbs, 2-pack
