About this product

Product Information

The ARRIS Touchstone TM822G is a telephony modem that is compatible with most major Internet providers in the U.S. Telephony modems are cable modems that are streamlined and specifically designed for VoIP, which is a form of voice communication that doesn’t require traditional telephone landlines. Users can enjoy conversations with family and friends around the world using their Web connection. Long distance calls are not differentiated from local ones, which provides convenience.It’s important to note that the ARRIS TM822G modem can be used for more than just telephony. You can use it to connect to the internet and surf the Web as well. The TM822G modem is often provided to cable users as a small network hub, so its efficiency in this area has been tested. It features multiple RJ-45 Ethernet connections. One is reserved for a router connection. Another two are reserved for phone connectivity. The remaining ports can be connected to computers and other LAN-capable devices. Users can even connect a wireless access point to expand their networking possibilities.Although you can connect the ARRIS TM822G modem to a wired or wireless router, it can also provide dual capacity as a cable modem and router. In a common scenario, it can connect to your Internet service or serve as a gateway to a phone. It can also provide connectivity to a desktop or laptop computer. If you do connect it to a router, then this device can operate in bridge mode. In this mode, the device will operate as an extension of the main networking device. A common scenario where this is used is adding a VoIP phone or two to a home network. It can then serve multiple computers, mobile devices, and phones.The ARRIS TM822G modem implements the DOCSIS 3.0 standard. The Data Over Cable Service Interface Specification dictates how data is transmitted and received. This cable modem takes full advantage of the speed and other enhancements of DOCSIS 3.0. It’s also fully backward-compatible with DOCSIS 2.0, 1.1, and 1.0 communication. If your service company offers tiered data services, the TM822G can take advantage of those. It uses an 8 by 4 configuration, which means eight upload channels and four download channels. It can achieve a download speed up to 343 Mbps.The TM822G cable modem comes a power cord, a battery, and a CAT5e cable. The battery type is Lithium-ion, and it has been installed for backup purposes. If used, the power pack will kick in during a power outage to maintain the modem and its phone service. This is particularly helpful if you live in an area prone to storms or other interruptions.The front panel has eight indicators. These include power status and battery level. It also indicates line in use for telephone number one and two. The Ethernet link will be green for a solid connection and yellow for a poor connection. Another light indicates online status, and upstream and downstream lights will blink as data is sent and received. The rear panel provides a power connection, a reset button, a LAN connection, and two telephone line connections.

Arris TM822G - Terrific modem - Install easy and not easy.
The TM822G is a terrific Docsis 3.0 modem. I get 8 solid downstream channels and 3 upstream. My service is the Comcast 75 Mbps and I get about 90 Mbps down and 6.0 Mbps up. Installation of the one that I got was problematic for two reasons, both addressable: 1. It was a used modem that had been previously provisioned on the Comcast network, thus the guided provisioning that should have occurred didn't work. When I called Comcast, apparently they couldn't tell that a modem was previously provisioned on their network. So I spent a lot of time with a pleasant Comcast person and then gave up. When I called back and told them it had been previously provisioned, it took a while but it got set up successfully. 2. When I tried to get it working with my router, that didn't work. After numerous attempts on my own, I then spent some time with a not very knowledgeable Comcast person and then gave up. I was about ready to box it up and return it when I came across some notes from the last time that I had problems setting up a new router with my Comcast modem. I followed them to a T and the modem and router connected on the first try. They are at below. (Note: After my initial router set up I have not had to follow these instructions. __________________ To reset Comcast modem/wireless Router connection 1. Unplug the Ethernet cable that connects the Comcast modem and the wireless router. 2. Reset the Comcast modem by using the paper clip to depress the switch in the small round hole on the bottom of the modem. 3. After the Comcast Modem restarts (once two lights come on) immediately plug the Ethernet cable back in. Then wait a few minutes for them to establish communication. Note: This will not work if you let the modem finish its restart or if you plug the Ethernet cable in before it begins its restart.Read full review

Didn't get a chance to use it
My ISP (WAVE Broadband) would not support the telephony function of the modem, so I never got a chance to try it out. I was told that it would support my internet, but no phone service. Apparently, the only place to get an internet/telephony modem for WAVE is from WAVE.

Perfect modem, for Optimum
Optimum had us down, for only 10 minutes, the largest part of which was the physical cable switching and synchronizing of the new modem, to their system. After that, we were back up, at a 1Gb transfer rate. This is a perfect modem, for those who are tired of paying Optimum that monthly rental fee, for the modem they supply. All you need do is call Optimum, give them the CMAC number, printed on the back of your new modem, then swap the power and data cables, all of which are in identical positions to their old modem. They do the rest, remotely, to activate the new modem.

Overall good broadband modem w/VOIP
Good modem with VOIP support. It also features and lithium battery backup that can keep it going for hours in case of a sever power failure in the mains. There is nothing wrong with setting up a small air fan near this modem (and/or your wifi router, too). Such fan would keep your Internet/LAN devices working longer AND noticeably more stable.

Works with NJ optimum 200 Mbp
It works fine with my internet provider Optimum in NJ. However, sometimes there is a lag or speed reduction that I think it is the Optimum problem not the product issue since I have tested multiple modems with different brands. Optimum has certified only a few brands and models and this modem is one of them. Although it works better than others for continuous and reliable connection, but still it has some issues with Optimum. Nonetheless, this modem works better than rivals with Optimum.
