ALS-R60 8U 20-Slot ADSL Splitter Rack

ALS-R60 8U 20-Slot ADSL Splitter Rack

The ALS-R60 is a 8U, 20 slot, 19(23)" rack mountable chassis for concentrated central office POTS splitters used in conjunction with ADSL DSLAMs. The chassis motherboard is available only with wire-wrap POTS and Line connections and HDB78 pin connectors for 32 loop per card DSLAMs. Each physical card provides 32 loops each of ADSL line splitters which provide low-pass filters designed to provide POTS (Plain Old Telephone System) service to a line that is utilizing ADSL technology. This device is designed to eliminate interference to POTS equipment by blocking the high frequency ADSL signal (20 KHz~12 MHz).

Features:

  • 8U 19(23)" rack
  • Consists exclusively of all passive elements
  • Designed for implementation of ADSL CO application
  • Handles all POTS loop current from 0 ~ 100mA
  • If the power on ATU-C / ATU-R fails, telephone service on the ADSL line will operate normally
  • Provides excellent isolation between DSL and POTS
  • Up to 20 cards (640 loops Max)
