ALS-10-EU/ISDN CPE ADSL Splitter for ADSL over ISDN

CPE ADSL Splitter for ADSL over ISDN

The ALS-10-EU/ISDN is a low-cost, compact, low pass filter designed for ISDN-BA with 2B1Q or 4B3T baseband line codes coinciding with ADSL signals. It integrates a low pass filters that block the high frequency energy from reaching the ISDN-BA device and provides isolation from impedance effects of the ISDN-BA device on the ADSL modem. Because the ISDN splitter connects directly to the subscriber loop media, it must also provide some protection for externally induced line hits or faults which could damage to any attached equipment or endanger humans interacting with the installed equipment. The circuit protection will be provided mostly by standard central office line protection means and additional protection measures built into splitter to protect against line overstress which could damage the splitter itself. The electrical and transmission specifications are based on ETSI TS 101 952-1-3 V1.1.1 for ISDN-BA requirements.

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.

The ALS-12 / ALS-M12 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. This device is designed to eliminate interference to POTS equipment by blocking high frequency energy (20 KHz~12MHz). The ALS-12 provides point of entry filter to split the incoming line to the ADSL/VDSL modem and the POTS telephone. The ALS-M12 is a micro-filter designed to simply drop a POTS telephone off a line carrying ADSL/VDSL signal.

The ALS-P10 filters with Siemens/Krone type terminals, can be directly plugged into the existing terminals at central office one by one, as needed, thus eliminating need for extra terminal blocks and cabling. This leads to lower costs compared with ordinary splitters deployment, which requires operators to install large splitter racks and equipment awaiting presumable future use. With the ALD-P10, no extra cabling or terminal blocks are needed and with Krone LSA Plus terminals, only minor new cabling is needed. The plug type filters are easy to install onto the terminal blocks with no extra tools required. Filters act like disconnection plugs in that the contacts inside the terminal are disconnected and the filter connects in series to the loop pair. The plug type splitter requires the space of two pairs of LSA Plus terminal block. Individual filters can be plugged adjacent to each other and will not block neighboring pairs from insertion of new wires. Thus ADSL can be connected to subscribers independently.
