SAN DIEGO--(BUSINESS WIRE)--May 14, 2002

ADSL POTS Splitter Eliminates Operational Costs and "Truck Rolls" for

Telcos

Pulse, a Technitrol company (NYSE:TNL), today announced the availability of an asymmetric digital subscriber line (ADSL) splitter with excellent attenuation at DSL frequencies using a special filter topology, customized for plain old telephone system (POTS) configurations in Japan.

The splitter meets the demanding ITU-G.992.1 Type E4 Japan requirements and has Japan Approval for Telecommunication Equipment (JATE) certification. It also meets the ITU-K.21 lightning surge protection requirements.

The lightweight splitter is easily self-installed, avoiding delays associated with sending a technician to the customer's home. Broadband subscribers can request a kit with an ADSL modem and the customer premises equipment (CPE) splitter. The splitter simply plugs into the home's primary telephone jack. Telephone and modem connections are indicated on the filter ports.

The splitter's function is to separate the high-frequency ADSL signal from the lower-frequency plain old telephone service (POTS) signal. It uses a special filtering topology that blocks noise and interference between ADSL and analog telephone equipment by isolating voice-band devices and telephone network jacks. Customers receive the high-speed ADSL services they expect with the existing wiring found in most homes.

Technical Information

The Japan ADSL splitter has a POTS impedance of 600 ohms with voice band delay distortion of 250 microseconds. The ADSL attenuation (30 kHz-1.1 MHz) produces a minimum of -65 dB and the ADSL disruption (30 kHz-1.1 MHz) produces a maximum of -0.25 dB. For more technical information refer to Data Sheet B801, located on Pulse's Web site at http://www.pulseeng.com/pdf/B801.pdf.

Pricing and Availability

The new ADSL splitter part number B2351 (without common mode choke) and B2396 (with common mode choke) are currently available with color and telephone cord options. The splitters are shipped in bulk with prices starting at $2.50 U.S. per unit in quantities of 100,000. Lead time is four to six weeks. Volume discounts are available.
