ARRIS Touchstone TM1602A DOCSIS 3.0 Upgradeable 16x4 Telephony Modem for TWC & Optimum (Renewed)

I finally got around to buying this so I no longer have to rent from Optimum, and I'm glad I did.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).

Work great so far. Great price

I tried to link this up to Optimum, and it worked for a good week or two, until it frizzed out and stopped turning on all together. I was able to get a replacement, but the replacement keeps turning off and on again, leaving me with times I can't get internet. Absolute disaster, please avoid this modem listing at all costs.The store selling it is shady too, the address might not even be real, and it's reported their selling stolen equipment. I wish I had avoided this listing. Don't fall for the same thing I did too.I'm trying to find a replacement modem for Optimum, but I still can't find, I'll update this review when I find a reliable option with Phone and Internet services.

The ARRIS Touchstone TM1602A has been a worthy addition to our home. 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!

For whatever reason the phone part of this modem is not working and my ISP is unsure of whether it is the MODEM or them so are sending a technician in 2 days. I tried contacting Arris and this product is not retailed by Arris and they make it quite clear they provide NO support on their website. Now I do believe that should be included in the amazon description of the product and it is not, but when I called technical support they felt that the fault was probably Optimum's but to ensure that all goes smoothly are sending a second modem just in case the first does have an issue with telephone capability. I find that proactive attitude commendable. Very impressed. Thanks much

took some time for my cable company to assume the modem in their network. other then that works perfectly

Refurbished modem works with Optimum. I had to get Optimum on the telephone to have the new CMAC address authorized.

Worked wall for about eight months but started to give problems shortly after. I replaced with another advanced technology device and everything has been good after that.
