The SP-206E splitter is a low frequency filter and it is intended for dividing low frequency telephony signal (voice signal spectrum) and high frequency ADSL signal. The SP-206E is placed at the phone line input (before phone connection). Thus, using the splitter excludes interference of modem and phone signals, providing concurrent operation of the devices. This splitter is equipped with the elements protecting the device against impulse over voltage and crosstalk. ADSL, ADSL2, ADSL2+ Annex B standards are supported.
