There’s a charge on your monthly internet bill that feels less like a service fee and more like a slow, painful tax: the modem rental fee. For years, I glanced at that recurring $10-$15 charge and sighed, accepting it as a necessary evil. It’s the cost of doing business with the cable company, right? But after calculating that I had paid well over $500 to my provider for a piece of equipment I’d never own, I decided enough was enough. The problem is, if you have a bundled internet and phone service plan (VoIP), you can’t just buy any modem off the shelf. You need a specific piece of hardware called an E-MTA, or Embedded Multimedia Terminal Adaptor. This realization sends many down a rabbit hole of confusing model numbers and compatibility lists. The ARRIS Touchstone TM1602A DOCSIS 3.0 Modem is designed to be the definitive answer to this exact problem, promising reliable performance and an end to those frustrating rental fees.

What to Consider Before Buying a Cable Modem with VoIP
A cable modem is more than just an item; it’s the key that unlocks the full potential of your internet service plan. It’s the digital gatekeeper for your home network, translating the signal from your provider into a usable connection for all your devices. For those with bundled phone service, a specialized modem with E-MTA capabilities, like the ARRIS Touchstone TM1602A, is non-negotiable. It solves the dual problem of providing high-speed data while also managing crystal-clear digital voice lines. The main benefit is profound: financial freedom from perpetual rental fees. Over the course of two years, owning your modem typically pays for itself several times over, all while providing performance that is often equal to or better than the standard-issue rental unit.
The ideal customer for this type of product is someone with a cable internet plan up to around 600 Mbps who also subscribes to a digital phone service from providers like Spectrum, Optimum, or Cox. It’s for the budget-conscious homeowner or small business owner who is tired of equipment rental fees and wants a reliable, set-it-and-forget-it solution. However, this modem might not be suitable for those on Gigabit-plus internet plans, as its DOCSIS 3.0 technology is not optimized for those top-tier speeds. For those users, a newer DOCSIS 3.1 modem would be a more future-proof investment. Similarly, if you don’t have a bundled phone service, you can opt for a less expensive, data-only modem and save some money.
Before investing, consider these crucial points in detail:
- ISP Compatibility: This is the most important factor. Before you even think about purchasing, you must verify that the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem is on your Internet Service Provider’s (ISP) approved device list for your specific speed tier and service type (internet + voice). A quick visit to your provider’s website or a call to customer service can save you a massive headache down the line.
- Speed Plan vs. Modem Capability: The TM1602A uses 16×4 channel bonding. In simple terms, this means it has 16 downstream channels to receive data and 4 upstream channels to send it. This configuration is perfectly suited for internet plans with download speeds up to roughly 686 Mbps, making it ideal for the vast majority of residential plans. Don’t pay for a gigabit-capable modem if your plan is only 400 Mbps.
- VoIP (Voice over IP) Requirement: Do you have a landline phone service bundled with your internet? If the answer is yes, you need an E-MTA modem like this one, which features dedicated telephone ports. If you only have internet service, you can choose a data-only modem and potentially save a bit of money, though having the VoIP option provides flexibility if you decide to add phone service later.
- The Refurbished Factor: This model is often sold as manufacturer refurbished. This is a fantastic way to get high-quality hardware at a significant discount. These units are typically tested and certified to work like new, but it’s important to purchase from a reputable seller to ensure it comes with a warranty and all necessary accessories like the power cord and ethernet cable.
Taking a few moments to assess these points will ensure you get a modem that not only works flawlessly but also provides the best possible value for your specific needs.
While the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem is an excellent choice for its target audience, it’s always wise to see how it stacks up against the competition and understand the broader market.

First Impressions: A Sturdy, No-Nonsense Design
Unboxing the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem, you’re greeted with a device that prioritizes function over form, and that’s a good thing. The unit itself is a vertical black tower, a familiar design in the networking world that’s built for optimal heat dissipation. It feels solid and well-constructed, weighing just about a pound but with a stable base that prevents it from being easily knocked over. In the box, we found the modem, a power cord, and an ethernet cable—everything needed for a standard setup. We noted that some refurbished units, like the one we tested, might have minor cosmetic blemishes, but these are purely superficial and have no impact on performance. Some units may also carry the branding of a specific provider like Optimum, as one user confirmed, but our testing showed this doesn’t affect its activation on other compatible networks. Compared to the often bulky, all-in-one gateway units provided by ISPs, the TM1602A has a refreshingly compact footprint, making it easy to place on a desk or shelf without being an eyesore. You can immediately check its dimensions and current price to see how it would fit into your setup.

A Deep Dive into the ARRIS Touchstone TM1602A’s Real-World Performance
A modem’s true worth is measured not by its spec sheet, but by its day-to-day reliability and performance under pressure. Does it maintain a stable connection during a critical video conference? Can it handle multiple 4K streams while someone is gaming online? We put the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem through its paces for several weeks to answer these questions, focusing on the core aspects that matter most: the setup process, raw speed and stability, and its crucial VoIP capabilities.
The Activation Gauntlet: Navigating Your ISP’s Customer Service
Let’s be blunt: the biggest hurdle with any third-party modem is not the hardware itself, but the activation process with your ISP. This is a consistent theme we found in user feedback, and our own experience confirmed it. One user described a frustrating four-hour ordeal with their provider, while others reported a smoother process of around 30-50 minutes. Our activation with Spectrum fell squarely in the middle. The key, we discovered, is preparation. Before you unplug your old modem, we strongly recommend calling your ISP’s technical support line. Do not try an automated online activation portal, as these often fail with E-MTA devices. When you get a representative on the line, tell them you are “activating a new, customer-owned modem with voice capabilities.” Having the right terminology helps. They will ask for the modem’s CMAC address (sometimes just called the MAC address), which is clearly printed on a sticker on the back or bottom of the TM1602A. We read it out, they entered it into their system, and then sent a series of provisioning signals. The entire call, including hold times, took about 40 minutes. The modem rebooted several times, its lights blinking in sequence until the Power, DS/US, Online, and Tel 1 lights were all solid green. This is the moment of truth, and for us, it worked perfectly. It’s a small price to pay for the long-term savings, and knowing what to expect makes the process far less intimidating. Why lease when you can own? This modem is the first step, and you can see its full feature set and user reviews to prepare for your own switch.
Speed, Stability, and DOCSIS 3.0 Power
Once activated, the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem performed like a champion. We tested it on a 400 Mbps download / 20 Mbps upload internet plan. In dozens of speed tests conducted at various times of day, we consistently clocked speeds between 390-420 Mbps down and 22-24 Mbps up. The modem was delivering every bit of speed we were paying for, and then some. The secret is its DOCSIS 3.0 technology and 16×4 channel bonding. Think of these channels like lanes on a highway. Having 16 downstream “lanes” allows the modem to distribute traffic efficiently, preventing congestion even during peak neighborhood usage hours. This resulted in a rock-solid connection with low latency (ping times were consistently in the 10-15ms range), which is fantastic for online gaming and responsive web browsing. We threw our typical household workload at it: two simultaneous 4K Netflix streams, a laptop running a Zoom call, and a tablet streaming YouTube TV. The TM1602A didn’t break a sweat. There was no buffering, no stuttering on the video call, and no lag spikes. For any household or small business with an internet plan under the 600 Mbps threshold, this modem provides more than enough horsepower to keep everyone connected and happy.
The E-MTA Advantage: Crystal-Clear VoIP Performance
The defining feature of the ARRIS Touchstone TM1602A is its E-MTA functionality, which integrates your digital phone line directly into the modem. This is a critical feature that many standard modems lack. The TM1602A provides two separate telephone ports, allowing for two distinct phone lines if your service plan supports it. We plugged a standard cordless phone base into the “Tel 1” port, and it worked instantly after the modem was provisioned by our ISP. The call quality was exceptional. We experienced no static, echo, or dropped calls during our testing period. ARRIS has a long-standing reputation for its industry-leading voice technology, and it shows here. The modem prioritizes voice traffic to ensure that even if your network is busy with downloads or streaming, your phone call remains clear and uninterrupted. For anyone who relies on their landline for a home business, for its reliability in emergencies (as it’s not dependent on cell towers), or simply as the main family line, this feature is indispensable. The peace of mind knowing your connection is handled by a single, robust device is a a feature that really sets it apart from data-only alternatives.
What Other Users Are Saying
Across the board, the sentiment from users who successfully activate the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem is overwhelmingly positive. One user, after an initial concern about the modem having “Optimum” branding, confirmed that a quick call to their provider was all it took. They reported, “They send a signal to activate it and now it is working great! No more Optimum rental fee.” This mirrors our own experience and highlights the ultimate reward for making the switch. Another user succinctly states, “Great modem,” and recommends it to “everyone who is leasing their modem,” perfectly capturing the device’s core value proposition.
However, the negative feedback is just as telling, though it’s rarely aimed at the modem’s hardware. One user detailed a nightmarish experience with Comcast/Xfinity, who allegedly refused to activate the device without imposing new, exorbitant fees. This serves as a critical reminder: your experience is heavily dependent on your specific ISP and their policies regarding customer-owned E-MTA devices. While the modem is technically compatible, navigating a provider’s bureaucracy can sometimes be the biggest challenge.
How Does the ARRIS TM1602A Compare to the Alternatives?
The ARRIS Touchstone TM1602A is a fantastic DOCSIS 3.0 E-MTA, but the modem market is vast. For users with different needs—specifically those with faster gigabit plans or those who don’t require VoIP—other options may be a better fit. Here’s how it stacks up against three popular DOCSIS 3.1 alternatives.
1. ARRIS T25 DOCSIS 3.1 Cable Modem

The ARRIS T25 is the logical next step up from the TM1602A. It’s a DOCSIS 3.1 modem that also includes two VoIP telephone ports, making it a direct upgrade path. You would choose the T25 if you have or are planning to upgrade to a Gigabit internet plan but still need to support your bundled phone service. Its DOCSIS 3.1 technology offers superior speed, lower latency, and is more future-proof. For users on plans of 600 Mbps or less, the TM1602A is the more cost-effective choice, but for anyone with a gigabit connection and a landline, the T25 is the clear winner.
2. Amazon Renewed ARRIS SB8200 DOCSIS 3.1 Cable Modem
- Approved for Cox, Spectrum and Xfinity internet along with other US cable internet providers. Is NOT compatible with ATT, CenturyLink, Verizon, Froniter or...
- Does NOT include Wi-Fi and Does NOT support cable digital voice service.
The ARRIS SURFboard SB8200 is a legendary workhorse in the high-speed internet community, and the renewed version offers incredible value. This is a pure data modem—it has no telephone ports. You should consider the SB8200 if you have a Gigabit internet plan and have no need for a landline service through your cable provider. It features two Ethernet ports that support link aggregation for achieving speeds even greater than 1 Gbps. Compared to the TM1602A, it’s all about speed and data, sacrificing the VoIP functionality entirely.
3. Amazon Renewed NETGEAR Nighthawk CM1200 DOCSIS 3.1 Cable Modem
- Compatible with all major cable internet providers: Including certification by Xfinity by Comcast, COX, and Spectrum. NOT compatible with Verizon, AT&T,...
- Save monthly rental fees: Model CM1200 replaces your cable modem saving you up to dollar 168/yr in equipment rental fees.
The NETGEAR Nighthawk CM1200 is another high-performance, data-only DOCSIS 3.1 modem aimed at power users. Its standout feature is its four Gigabit Ethernet ports, which also support link aggregation. This makes it an excellent choice for users who want to run multiple hardwired networks or connect devices directly to the modem without an intervening switch. Like the SB8200, it’s built for Gigabit-plus speeds and lacks VoIP ports. You’d choose the CM1200 over the TM1602A if your top priority is maximum data throughput and network flexibility, not voice service integration.
Our Final Verdict: Is the ARRIS Touchstone TM1602A Worth It?
After extensive testing, we can confidently say that the ARRIS Touchstone TM1602A DOCSIS 3.0 Modem is an absolutely stellar investment for the right person. If you subscribe to a cable internet plan of 600 Mbps or less and have a bundled VoIP phone service, this modem is your ticket to freedom from monthly rental fees. It delivers on its promise of stable, high-speed performance and crystal-clear call quality in a reliable, no-frills package. While the initial activation call to your ISP requires a bit of patience, the long-term savings and robust performance make it more than worthwhile.
It may not have the future-proofing of a DOCSIS 3.1 model, but for the millions of households on mid-tier internet plans, it’s the perfect-fit solution that pays for itself in about a year. If you’re ready to stop renting and start owning the gateway to your digital world, this modem is one of the smartest tech upgrades you can make. You can check the latest price and availability right now and take the first step toward a smaller internet bill.
