This is fully compatible with Optimum's cable internet up to a 960Mbit connection. As you can see in the photo I'm only subscribed for a 300Mbit-down/20Mbit-up connection and I'm getting that and a bit more. If it wasn't listed as a refurbished item, and didn't come in an unlabeled brown box, you'd think it was brand new; No blemishes, dirt, or damage that I could discern. Pros: Cost - Will pay for itself after only 4 months. Performance - Theoretical maximum downstream speed of 960Mbits and 192Mbits upstream. Bundled in package - 6ft/1.8m coax and ethernet cables included. Cons: None yet. If the device fails at any point I'll edit this review, but these modems are pretty simple and have fairly long expected lifespans. Summary: If you're considering it, I recommend it. You'll save money each month by not renting from your ISP. The model I received has 24 downstream channels, not 16 as the description states - a nice surprise. (See photos). Note that this model does not have a backup battery compartment like some of the older Arris models such as the TM822. Additional notes: When you call your ISP to activate the MAC address on your new modem, be sure to give the tech the CMAC address (sometimes referred to as HFCMAC) - The C is for CABLE and that is how the device is provisioned on the ISP end. The MTAMAC address is for telephony, and the tech should be able to identify that after provisioning the CMAC first. (If you don't have a VoIP line with your ISP, this is unnecessary). Review: Works for Optimum/Altice - Worked for Optimum/Altice, however, only way to register the modem is to call optimum. Self registration online only works for their modem. You'll need to provide them the CMAC# on the label under the modem. After they registered the modem, it took several reboots to come online. Otherwise straight forward swap out. There is no documentation telling you that you must call to register the 3rd party modem. Bought refurbished unit but a month in so far so good. It was cheap enough that I decided to purchase a 2nd as a backup in case this one fails; WFH some days so I can't be out for any length of time. ## Features - Package Dimensions- 9.398 L X 31.826 H X 24.13 W (Cm) - Product Type-Modem - Package Quantity-1 - Package Weight-1.79897205792 Lbs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07CSDSBZB | | Best Sellers Rank | #65,715 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #206 in Computer Networking Modems #7,348 in Renewed Computers & Accessories | | Brand | ARRIS | | Color | black | | Compatible Devices | Personal Computer, Router | | Connectivity Technology | Cable | | Customer Reviews | 4.1 out of 5 stars 1,084 Reviews | | Data Transfer Rate | 960 Megabits Per Second | | Internet Service Provider | TWC, Optimum | | Internet service provider | TWC, Optimum | | Item Dimensions L x W x H | 7.1"L x 1.8"W x 7.1"H | | Manufacturer | Speck | | Maximum Upstream Data Transfer Rate | 1104 Megabits Per Second | | Mfr Part Number | TM1602A | | Model Number | TM1602A | | Modem Type | Voice | | Number of Ethernet Ports | 2 | | Number of Ports | 2 | | Product Dimensions | 7.1"L x 1.8"W x 7.1"H | | UPC | 099651934376 | | Warranty Description | 90 days limited warranty | ## Images ![ARRIS Touchstone TM1602A DOCSIS 3.0 Upgradeable 16x4 Telephony Modem for TWC & Optimum (Renewed) - Image 1](https://m.media-amazon.com/images/I/612a+iLb5JL.jpg) ![ARRIS Touchstone TM1602A DOCSIS 3.0 Upgradeable 16x4 Telephony Modem for TWC & Optimum (Renewed) - Image 2](https://m.media-amazon.com/images/I/71nmF6nx-SL.jpg) ![ARRIS Touchstone TM1602A DOCSIS 3.0 Upgradeable 16x4 Telephony Modem for TWC & Optimum (Renewed) - Image 3](https://m.media-amazon.com/images/I/41c-qY4aShL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Value on Refurb - Recommended *by S***N on August 16, 2022* I finally got around to buying this so I no longer have to rent from Optimum, and I'm glad I did.

Self registration online only works for their modem. You'll need to provide them the CMAC# on the label under the modem. After they registered the modem, it took several reboots to come online.

Straight off the bat, by purchasing this modem, we've managed to cut down our monthly expenses, saving over $11 a month on Optimum's rental costs. It's always a win when you can acquire equipment that pays for itself over time! Performance-wise, the TM1602A delivers reliably. We've experienced consistent internet connectivity with minimal disruptions, which, given today’s digital demands, is absolutely crucial. The setup was straightforward, and the device has so far proven durable. We will still have to call Optimum tech support to complete setup. However, the world of modems offers a spectrum of advanced options, and while the TM1602A functions admirably, it wouldn't be hailed as the absolute best in the broader market. My main gripe, which leads to the deduction of one star, is the limited flexibility with Optimum. While I understand the constraints of needing a modem with phone line compatibility, it's slightly disappointing that this is the only model Optimum permits for such a setup. Nonetheless, for anyone bound by the same constraints and looking to save on rental costs, the ARRIS Touchstone TM1602A is a commendable choice. If you have a large house, pair this with Eero 6, and you will have the best Wi-Fi speeds and connections you can get! --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/78441250-arris-touchstone-tm1602a-docsis-3-0-upgradeable-16x4-telephony-modem](https://www.desertcart.sn/products/78441250-arris-touchstone-tm1602a-docsis-3-0-upgradeable-16x4-telephony-modem) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-05-20*
