Best ZOOM TELEPHONICS Computer Networking Modems in 2022

Zoom Telephonics Demon Dialer Computer Networking Modem

In 1983, Zoom engineers began diversifying their product line, starting with the MB8600. Then, a field applications engineer from National Semiconductor created a 300-baud modem for the Apple Computer. Manning and Kramer approached them and convinced them to accept an offer to manufacture and sell the product through the Massachusetts Technology Development Corporation. The next step was to sell the modem.

Demon Dialer

The phrase "demon dialing" has multiple definitions. It originally referred to repeated calls to a single modem in an attempt to guess the password. The term has also been used to refer to war dialing. Zoom Telephonics sold a telephone dialer called the Demon Dialer, which could redial busy numbers until the call went through. This invention quickly became a synonym for computer hacking.

During the early days of WWIV, it was necessary to build a network of local phone numbers in order to connect. Computers on BBS networks communicated by synchronizing data packets. Users of WWIV were notorious for typing up dozens of numbers to make a phone call. To overcome this problem, a "demon dialer" was invented. This software program kept dialing a small set of numbers until it connected. It proved useful for winning contests, getting tickets, and annoying customer service representatives.


The MB8600 from Motorola is a $150 modem that is a welcome upgrade for sub-gigabit and Gigabit cable broadband users. It is compact and looks like a typical cable modem, but it is capable of Gigabit speed. It features a single Gigabit network port and a Broadcom Full-Band Capture digital tuner.

This computer networking modem comes with an ARM-based application processor and 512 MB of RAM. Its low-latency capability makes it perfect for connecting any device with an Ethernet port. It is certified by Comcast XFINITY, Comcast Business, and Cox Communications. It can save consumers over $120 per year in cable modem rental fees. Its low price makes it a great option for many users.

The Zoom MB8600 is made of durable plastic and has a glossy black finish. The MB8600 has many cutouts for proper airflow, which keeps it cool.

If you are considering this computer networking modem for your business, it is a great choice.


The ZOOM TELEPHONICS MC7621 Computer Networking Modem is an excellent choice for many reasons. The modem can be used for a wide variety of applications, including wireless, wired, and wireless. It has an intuitive interface that makes setting it up a snap. The included software helps users connect to their home network, and a built-in LAN manager makes it easy to configure settings and maintain a secure connection.

The MB7621 uses the Broadcom platform and features Full-Band Capture technology. Its 24 downstream channels enable speeds up to 1,000 Mbps. Zoom claims that the device supports up to 1Gbps, but there is no evidence to support this claim. It's a good idea to check with your internet provider for speed specs. Unless you're a heavy Internet user, you won't have any trouble getting a good download and upload speed.

With its simple setup, the ZOOM TELEPHONICS MC7621 Computer Networking Modem allows you to configure and manage multiple devices. It also features a security feature that makes it ideal for use with public Wi-Fi. Ultimately, you'll have fast Internet for many devices. You'll also be able to upgrade your service as needed.

MB7621 is faster than MB8600

The MB7621 is more powerful than its predecessor, but it's still far behind the MB8600 for computer networking. It features 512 MB of RAM and 128 MB of DWARF. In the future, it could bond up to four separate lines, allowing it to handle 4Gbps connections. But for now, its lower price is enough to make it an excellent choice.

This Motorola modem supports Gigabit internet plans and is backwards compatible with the 32x8 DOCSIS 3.0 standard. It is also supported by Grande Communications. The MB8600 uses the Broadcom BCM3390 chipset. It is made in the USA by Zoom Telephonic, which is highly regarded in the communications industry.

For computer networking, the MB7621 is faster, thanks to its four Gigabit LAN ports. While the MB8600 is faster, it is not as fast as the MB7621 for multi-gigabit speeds. Both modems have the same setup process, so there's no need to worry about getting stuck with a complicated manual. Getting your new modem running is as easy as calling your ISP and following their instructions.

MB7621 is cheaper than MB8600

A comparison between the two Motorola computer networking modems should reveal a few key differences. The Motorola MB7621 supports DOCSIS 3.0, and is compatible with all major cable internet providers. It costs slightly less than the MB8600, but offers the same quality at a lower price. It also comes with a two-year warranty.

The Zoom 5370 works with the most popular ISPs, but it may not work with less popular ones. To avoid confusion, you can look at its compatible modem list or call your ISP. Make sure to make sure the modem supports full power, and that you will not encounter any speed caps. Once you've done this, you can proceed to purchasing your new modem.

In addition to the MB7621's price, the MB8600 has four Ethernet ports. Both can support up to 1Gbps of downstream traffic. Using a DOCSIS 3.1 computer networking modem will also improve your connection's speed and reliability. Its MB8600 rival can't support DOCSIS 3.1, so you'll need a modem that supports DOCSIS 3.1.

MB7621 is a decent looking modem

This computer networking modem comes with a nice, stylish case. The black casing is matte and doesn't hold fingerprints. The sides and top feature vent grills. If you are worried about the temperature of your computer, you can keep it in a cool, dry place. However, if you do plan on using the device in the home, it might be best to keep it in a dry place.

This computer networking modem is built on the Broadcom platform and comes with Full-Band Capture technology. As such, it won't have any latency problems. It features 24 downstream channels and can support speeds of up to 1,000 Mbps. While Zoom does not claim to support upstream speeds, it is still a decent-looking computer networking modem. Its price is reasonable for a 24x8 modem.

There are a few downsides to this computer networking modem. While the Zoom 5370 should be compatible with most popular ISPs, you should check the compatibility list before purchasing. If you don't see your ISP's list, you can call them to find out. Make sure that you can use the full power of the modem and that your ISP hasn't put any speed caps on it.
