ALS-10-IT CPE ADSL Splitter, Field for ITA, UK, FI, FR

CPE ADSL Splitter, Field for ITA, UK, FI, FR

The ALS-10 regional ADSL splitters are low-cost, compact, passive low-pass filters designed to provide POTS (Plain Old Telephone System) service to a line that is utilizing ADSL/VDSL technology and customized with regional country telephone plugs. This device is designed to eliminate interference to POTS equipment by blocking high frequency energy (20 KHz~12MHz). The ALS-10 provides point of entry filter to split the incoming line to the ADSL/VDSL modem and the POTS telephone.


  • Compact size
  • Consists exclusively of all passive elements
  • Designed for implementation of ADSL/VDSL CPE application
  • Handles all POTS loop current from 0 ~ 100mA
  • If the power of ATU-R fails, telephone service on the ADSL line will operate normally
  • Provides excellent isolation between DSL and POTS
  • The POTS splitter and Low-pass filter provide RJ-11 connectors for ATU-R/VTU-R and POTS interfaces
