Isolates ADSL and voice bands.
High quality product and services with double noise reduction and high progressive connection pick up.
ADSL splitters/filters is an electronic device that isolates the adsl and voice bands. An adsl line filter is required whenever you connect a computer to the internet using broadband over a standard telephone line. The filters divide the signals on the telephone line between the high pitched computer modem sounds and the lower pitched human voices.
External basic ADSL modem for single computers. Connection to PC is USB. ull rate speed support up to 8MBps
The modems are ANNEX A type and there is support for
major protocols: G.DMT, T1.413, PPPoA, PPPoE, T1.483

Detailed selling lead description
Fme is high-speed fiber optic modem with remote configuration based on asic circuitry technology. It supports user-selectable rates between n*64kbps (n=1--31) and 2048 kbps. The fiber interface is sc (single module).Transmission distance is up to 60km. The product fully conforms to part 15 of fcc regulation.
With remote configuration, the fme rate of user terminal follows the configuration of the fme of master terminal automatically without any other setup.
Data interface of fme can be v.35/v.24/rs232 or g.703. E1 rate supports framed mode and unframed mode, which are known as n*64 kbps (n=1--31) and transparent 2048 kbps. External clock, internal clock, and slave clock are supported.
With the function of integrated diagnosis, it can perform tests of local analog loop back and remote digital loop back to achieve end-to-end integrity test.
