Separating ADSL and POTS

The VESALA® AES-L2 double LP filter is designed to separate ADSL (Asymmetric Digital Subscriber Line) from POTS (telephone) when they are transmitted on a same wire pair and terminated by means of Krone LSA PLUS® MDF technology. The filter protects POTS from interference caused by ADSL signals and equally protects ADSL from transients generated by, for example, POTS dialling and ringing, and from impedance fluctuations.

Saving Costs with AES-L2

Typically AES-L2 is plugged into the POTS side LSA PLUS® terminal in a shelter type remote cabinet. The HP filtered pairs from DSLAM are connected parallel to the customer side terminals. Installation of shelter type remote cabinets may be problematic if integrated DSLAM splitters are used, since they typically require space consuming back-and forth POTS-side cabling and terminals. With AES-L2, need for extra terminals is minimized, as the LP filters of AES-L2 together with DSLAM’s HP filtered inputs provide a sufficient ADSL/POTS separation. AES-L2 filters can be plugged into the LSA PLUS® disconnect module terminals one by one, as needed, which results in cost savings during installation.

Even later on AES- L2 allows unparalleled flexibility: if an individual subscriber gives up ADSL service, AES-L2 is simply removed from the terminal and the POTS line remains intact. AES-L2 is easy to plug to LSA PLUS disconnect module terminal test & measurement slots – no tools are needed. The two LP filters of AES-L2 connect to respective pairs directly via contacts inside the terminal. Individual filters can be plugged into terminals adjacent to each other. AES-L2 has symmetric mechanical shape, which allows best access to neighbouring terminals and their wire pairs.

Filter operation

AES-L2 contains two 2nd order passive low-pass filters. The corner frequency is 7kHz (±1kHz) and optimal matching 600ohms.

This Vesala product is made in Finland.
