Applications for the D-Series modems include those industrial strength applications where a rack mounting is required. a metal enclosure is required, or where the power source available is DC, rather than an AC wall outlet. It is ideal for telco installation, SCADA remote sites, or ISP POP locations. This is a current production product and DCB support is long-term. The D-Series is an industrial dial-up 56 Kbps V.90 modem. The modem can be powered with an external wall mount power supply, or can be powered by a 12, 24, or -48 volt dc supply. A rack front is available for the metal case, so it can be easily rack mounted with one, two or three modems per 1U rack height. A unique optional version is the "Processor" model D-series modem. This unit adds an additional processor to the modem that allows unique command sets to be emulated or programmed into the modem. Most often used to emulate command sets from obsolete modems or other devices, this is a custom feature that requires factory programming for the required changes and volume commitment.

Teardown: Inside a cable modem

Another is a chip from Texas Instruments for suppressing voltage transients on the USB interface. And a dc/dc controller chip supplies the various dc rails the chips need. A more interesting part of the PCB sits in a metal enclosure close to the cable input. The metal enclosure keeps out electrical noise and probably also prevents the modem from radiating RF. That part of the circuit operates at a much higher frequency than the cable modem chip or the rest of the board — The cable company typically delivers frequencies to the modem that are in the range of 50 to 860 MHz. There is a tuner chip in the shielded area that takes the incoming cable signals and reduces them to intermediate frequencies. The intermediate frequencies are in the 36 to 44 MHz range. Those intermediate frequencies get sent outside the metal enclosure to the cable modem chip. So I wish I could send a pic of the inside of my modem so someone could comment. I’ve been. Hacked for a year now and got a new cable and internet company and its seemed weird from the start. Now I open it and there is all these wires going from the outside and attatching to a metal piece on the main plate but it’s all put together with HOT GLUE!!! Broadcom devised a reference design using its single-chip cable modem. Other than different LED status lights and a more shielded RF front end, the reference design looks similar to the SA cable modem. In our teardown series this may have been the easiest product to get apart. The case is just two pieces that snap fit together.

If your wireless router's signal isn't as strong as you'd like, don't run out to buy a more expensive model. Though there are are many factors that influence the strength of a wireless signal, metal obstructions in a home or office are common culprits. Good Settings to Speed Up a Netgear Router. Like other routers, Netgear products come with... ... What Routers Work With an Open-Mesh Controller?. Open-Mesh is a brand of wireless Internet... Metal objects that come between your router and computer can obstruct signals. Areas of a home or office affected by metal obstructions are called "dead zones." Minimizing these dead zones will help you use your router to its full potential. If your router is positioned on a metal desk or near a metal wall, it makes sense to change the router's location to improve its signal. Additionally, positioning the router on a desk or shelf instead of the floor is another easy way to maximize performance. ... If moving the router away from metal obstructions and centralizing its location doesn't improve performance, physical barriers like metal may not be the source of interference.
