Business Editors/High-Tech Writers

SAN DIEGO--(BUSINESS WIRE)--Nov. 4, 2003

CPE xDSL Universal Splitter Fully Meets ETSI Specifications

Pulse, a Technitrol Company (NYSE:TNL), today unveiled its Excelsus(R) Z-BLOCKER(R) CP-404TJ, a digital subscriber line (DSL) splitter designed specifically for European telephone networks serving homes, small offices and multi-tenant units. The splitter functions on both integrated services digital network (ISDN) and plain old telephone service (POTS) lines. It meets or exceeds the customer premises equipment (CPE) splitter specification ETSI 101 952-1-4 for both 135 and 150 ohms, the most rigorous and demanding splitter specification in Europe. In addition, the CP-404TJ meets the stringent specification for German complex impedances. Offering either RJ45 or RJ11 port connections, the CP-404TJ is clearly marked with three separate jacks -- for the incoming phone line, the post-split phone line and DSL line.

The ETSI-compliant splitter provides filtering for all telephones, fax machines, answering machines and other devices throughout the home, enabling them to operate on the same line being used for high-speed Internet connectivity. The function of the CP-404TJ is to separate the high-frequency xDSL signal from the lower-frequency ISDN or POTS signal. The splitter protects phone devices from data signals to enhance voice-band quality. It also isolates xDSL from phone equipment impedances for peak Internet performance. The splitter meets the ETSI specification over ADSL, ADSL2, ADSL2+ and VDSL.

The Excelsus CP-404TJ is a universal ISDN and POTS splitter that does not require a switch or jumpers to be configured by the installer for analog or digital telephone service. Designed for easy wall mount self-installation, the cost-effective CP-404TJ is CE marked and can be customized to meet specific marking requirements.

Excelsus DSL filters and splitters incorporate unique, industry-leading Z-BLOCKER(R) technology that demonstrates high performance voice and data characteristics with regard to insertion loss, return loss and stop-band isolation. In addition, the technology allows utilization of advanced manufacturing techniques that ensure low cost and high performance.
