Marketing Information

The Zoom Model 5370 is a 686 Mbps cable modem certified for money-saving own-your-own cable modem programs by Comcast XFINITY, Time Warner Cable, and other leading cable service providers. Owning a certified own-your-own modem eliminates modem rental charges that are typically $8 to $10 dollars per month. Model 5370 is qualified for the highest speed cable services currently available, including Comcast XFINITY's Extreme 250 and Time Warner Cable's 300 Mbps Ultimate. The Model 5370 Gigabit (10-100-1000 Mbps) Ethernet port connects to your Windows or Macintosh computer, router, wireless access point, HomePlug adapter, or other Ethernet-enabled device. When used with a router, the high speed Internet service can be shared with multiple devices. The number of channels supported by a cable modem is the primary indicator of a modem's top speed. This modem is 16x4, which supports sixteen channels for downloads, and four channels for uploads. Sixteen channels for data downloads make this modem up to twice as fast as competing modems that support only eight channels. Because this 16x4 modem uses the cable network more efficiently, average download speeds can be faster, even for service speeds below the modem's top speed of 686 Mbps. The 5370 also uses a Full-Band Capture Digital Tuner that lets service providers deliver faster, more reliable Internet. The 5370 is certified by CableLabs to support the latest DOCSIS 3.0 standard plus DOCSIS 2.0 and 1.1 for use with older cable systems. IPv6 and IPv4 are supported for powerful, flexible network addressing. With its easy installation, high speed, and extensively tested compatibility, the Model 5370 is the perfect choice for almost any cable modem user. The Model 5370 has been tested and certified by CableLabs to work with nearly all U.S. cable services. The Zoom 5370 is covered by a two year warranty and quality technical support by Zoom Telephonics, a Boston based company founded in 1977.
