Conformity Assessment
-
For FCC approvals, we operate an accredited Telecommunications Certification Body (TCB).The TCB system was implemented in 2000 by the Federal Communications Commission (FCC). It was created to allow the FCC to step out of the product approvals role, and to focus more on regulating and market surveillance.Until this system was implemented, most products which intentionally radiate radio frequency energy, and products which connect to the public switched telephone network, were required to be certified with the FCC. This usually meant waiting several months for an approval to sell your product. Compatible Electronics TCB (CETCB) can certify these types of products generally in less than two weeks.

Telos Systems
-
Telos Systems—part of the Telos Alliance—was founded in 1985 by Steve Church, a talk show radio host and engineer who was dissatisfied with the poor quality of the on-air telephone calls on his shows. He was also an Engineer determined to do something about it. The resulting Telos 10 telephone interface system was a great success, inspiring Steve to build a business to make and sell the systems. Telos Systems has since become the industry leader in broadcast telephone systems and IP and ISDN codecs. The breakthrough Telos Zephyr audio codec, for example, is one of the most successful digital broadcast products in history, with more than 21,000 in use worldwide. Telos telephone hybrids and on-air talk show systems set the performance benchmark for the industry, and we continue to pioneer groundbreaking technology that pushes boundaries and gives broadcasters the telephony solutions they need for reliability, efficiency, and the best possible sound quality.

Utility Locator
VM-850
-
Using the correct frequency makes a world of difference when locating buried utilities. The depth of the utility, size, material, and amount of congestion (proximity of other utilities) all need to be taken into consideration for the correct frequency selection. Large diameter, direct buried pipes with bell housing ends that use insulators and rubber gaskets, such as water or gas require a higher frequency while smaller diameter, well-grounded direct buried or long distance in conduits work, better with a lower frequency. The VM-850 operates at a much lower frequency of 9.82kHz which is ideal for smaller diameter utilities such as CATV, power and telephone with less bleeding onto adjacent services.

AC / DC - Power Supplies
-
The spectrum of DC power supplies ranges from simple power adapters with only one output voltage to complex controllable power sources. Power adapters, often also called plug-in mains adapters, are mainly used for small electrical appliances (such as telephones, strings of light, notebooks, etc.) in private households. They are included in the scope of delivery of the product and only serve to supply power with a defined output voltage of 6 V or 12 V, for example. The output power is usually limited to < 200 W due to the simple design.
