Separating ADSL and ISDN
The VESALA® IS-E splitter is designed to separate ADSL (Asymmetric Digital Subscriber Line) from ISDN-BA (Integrated Subscriber Digital Network, Basic Access) when they are transmitted on a same wire pair and terminated by means of Krone LSA PLUS® MDF technology. The splitter protects ISDN from interference caused by ADSL signals and equally protects ADSL from ISDN frequencies and transients generated by, for example, current feeding to ISDN terminal equipment.
Saving costs with IS-E
The ingenuity of the design of IS-E splitters is that they can be plugged into LSA PLUS® terminal blocks in a local exchange, one by one, as needed. Ordinary splitters require an operator to install large splitter racks and equipment awaiting possible future use. With IS-E only one terminal block is usually needed for five subscribers. All this results in considerable cost savings during installation. Even later on it allows unparalleled flexibility: if an individual subscriber gives up ISDN, IS-E is simply removed from the terminal and the ADSL remains intact.
IS-E is easy to install to LSA PLUS® test & measurement slots - no tools are needed. The LP and HP filters of IS-E connect to respective pairs directly via contacts inside the terminal. Individual filters can be plugged into terminals adjacent to each other. Each IS-E requires a space of two pairs from a 10-pair terminal block. Symmetric mechanical shape allows access to neighbouring terminals and their wire pairs.
Filter operation
IS-E is a fully-featured, ETSI-compatible passive ADSL/ISDN low-pass & high-pass filter (splitter).
More detailed information on how to use IS-E can be found in the IS-E Brochure.
