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.
Adsl modem
Overview
The adsl ld-4202 is a high speed adsl2+ modem, combined an all-in-one adsl switch, usb, ethernet. The adsl ld-4202 supports adsl, adsl2 and adsl2+ over the existing copper lines, with downstream transmission rate up to 24mbps (adsl2+) and upstream transmission rate up to 1.024 mbps. They can support pppoa (rfc 2364 - ppp over aal5), pppoe (rfc 2516 - ppp over ethernet) and rfc 1483 encapsulation over atm (bridged or routed).
The adsl ld-4202 is capable of establish 2 connections at the same time with ethernet interface and usb interface respectively. It can provide the users over its usb or ethernet interface to share broadband access to the internet.
