## Description

The High-Speed Inter Modem Cable from Cables To Go provides for the fastest inter connection possible. Ordinary "included in the box" phone cables often use low-quality materials with little or no shielding which can result in poor performance. The High-Speed Inter Modem Cable connects your analog or digital modem to a telephone wall jack allowing for data transmission up to 10 times faster.Primary InformationNetwork Cable Type : Modem cable Cable Technology : Double shielded Left Connector Gender : Male Right Connector Gender : Male Left Connector Type : RJ-11 Right Connector Type : RJ-11 Networking / Compliant Standards : UL Features : 24k gold connectors; Snagless molded strain relief; Ultra-flexible jacket.

Review: The Ultimate DSL Cable - I ordered this 25' cable for a friend using a Verizon DSL modem. She was constantly experiencing drops in her internet as seen at the modem. Upon review of her setup, she was using a 25' telephone cable and a phone splitter from the wall. I replaced that setup with this C2G 25' cable and a actual DSL/phone splitter with a built in filter/choke. The results were remarkable! I won't say it totally eliminated all drops but close. This cable in well made more like a CAT 6 cable than a phone cable. If you're here, just buy it now! You will not regret it.
Review: Robust, high quality and good performance RJ-11 - Upgrade for our ATT DSL modem. Initial impression was “F¥€K they sent me RJ45 instead!”. LOL! Looks nothing like phone line. This is very robust, Ethernet style, round cable. Closer inspection revealed it did in fact have RJ11 connectors. Everything seems very well built and high quality. I have little doubt those cable will last a long time. As an added bonus, controlled experiments on our home network with speed testing shows 5% faster download and upload speeds from several providers. Latency has improved a similar amount. Coming from Walmart sourced ONN brand ordinary phone line that was 10 years old and had been through a few modem melting lightning storms. We still had issue free connectivity but since we’re replacing all our network hardware after the last storm we figured why not upgrade all the patch cables and the phone line as well.

### ⭐⭐⭐⭐⭐ Robust, high quality and good performance RJ-11
*by A***E on January 29, 2024*

Upgrade for our ATT DSL modem. Initial impression was “F¥€K they sent me RJ45 instead!”. LOL! Looks nothing like phone line. This is very robust, Ethernet style, round cable. Closer inspection revealed it did in fact have RJ11 connectors. Everything seems very well built and high quality. I have little doubt those cable will last a long time.

### ⭐⭐⭐⭐⭐ Perfect for UVerse VOIP router
*by P***D on June 18, 2020*

For a while I’ve been wanting to move my ATT VOIP router to a different location but the tech that installed it provided only a short wire. I always thought there was something cosmic about this type of wire due to the voice requirements over the internet line. Turns out these cables are readily available on the market, but they don’t explicably say it works with ATT voice and data routers. Well this one works perfectly. Great length at a great price. High quality material is sturdy yet professional looking. Voice and data with UVerse ATT works as advertised with no degradation of service. Highly recommend.
