Acterna Celebrates 25th Anniversary with the Wavetek Signal Analysis Meter by Showcasing SAM's Heritage of Test Support for Cable Operators; Company Commemorates Evolution of SAM as the Most Recognizable and Popular Name in the Industry.

GERMANTOWN, Md. -- Acterna, the leader in test and management solutions for consumer and business broadband communications, is celebrating the 25th Anniversary of the Wavetek SAM Meter, the popular test meter line that has grown from an indispensable signal analysis tool in 1980 to an award-winning, robust digital services activation meter (DSAM) today, consistently ensuring reliable, efficient and accurate test and management to cable operators.

The tribute, which includes a timeline that chronicles the SAM's evolution over the years and industry-first achievements, as well as other promotional presentations, will be on display at ANGA 2005, in Cologne from May 31- June 2, booth #J11, and at Acterna's Opening Night Reception at SCTE's Cable-Tec Expo in San Antonio, June 14 (and at Acterna booth #02081).

WaveTek Wandel Goltermann, which merged with TTC in 2000 to form Acterna, revolutionized cable-TV testing with the introduction of the Signal Analysis Meter, better known as the SAM, in 1980. The first SAM meter was recognized for setting the standard for all future cable test meters for its accuracy, reliability and ruggedness. From year to year, the SAM's enhancements reflected the issues and technology concerns that defined each era of cable-TV development.

"The SAM meter was truly a revolutionary testing tool in the cable industry, and the bread-and-butter of Wavetek - a company and product we are proud to have associated with Acterna's communications test heritage," said Mike Richardson, director of North America Sales for Acterna's Cable Network's Division. "We are celebrating 25 years of excellence for a cable test instrument widely recognized for ensuring reliable, high-quality service."

A time-honored meter -- which has grown from a pure cable-TV test instrument to an advanced triple-play solution under the DSAM brand -- following is a summary of the SAM's heritage:

1985-1990: Following SAM Jr. and SAM I, the SAM family grew with the introduction of the SAM II, SAM III (IIID) and SAM IV. These new versions were considered revolutionary for introducing the first keypad (followed by a fully digital keyboard interface), the first completely microprocessor-controlled SLM enabling pre-programmed channels and two-way test capability.

1987: The SAM family again made history with the introduction of the 1000 and 2000 series, which started the migration from analog to full digital displays with advanced features that were offered for the first time, including: digitally displayed channels, measurement level and frequency, as well as automated measurements (microprocessor).

1990: With the introduction of the FiberSAM and the LineSAM, the SAM family focused on the needs of more targeted markets by providing specific tests for specific job functions. The LineSAM for line techs, responding to the need for CN and HUM measurements, and the FiberSAM were developed to include a built-in fiber optic power meter used for troubleshooting fiber nodes.

1995: The SAM meter once again revolutionized cable testing with a new definition of portability and ease-of-use. The SAM 4040 design re-defines the concept of cable testing meters, introducing the "Sweepless Sweep" for non-intrusive frequency response.

2000: As cable services and technology became more complex, the SAM meter evolved to meet the industry's needs with the launch of the new DSAM-2500. New features included DSP and DOCSIS protocol to test cable modems, IP testing, Workforce Automation (WFA) Browser option, and return path view capability.

Today, the DSAM is the only handheld meter with an embedded PacketCable(TM) MTA to make and receive live VoIP calls via version 2.3. The new DSAM allows technicians to measure - and listen to - call quality, including MOS, on real-time phone calls and is the only meter with closeout test efficiency reports saving operators valuable time and resources.

About the DSAM

Acterna's Digital Service Activation Meter, part of Acterna's Application-Aware(TM) suite of test and management products, ensures provisioning completion, call availability and call quality margin at installs and service calls to reduce the repeated truck rolls on VoIP related issues. The DSAM helps keep up with rapid VoIP rollout while maintaining voice service quality, resulting in increased revenue and reduced turn-over rates. The DSAM utilizes the industry's only integrated embedded Multimedia Terminal Adaptor (eMTA) to measure true in-service call quality by placing real-time, physical VoIP calls through the operators' VoIP network. In addition to Ethernet IP throughput, ping, and packet loss performance testing, the DSAM has also enhanced its VoIP capability by adding the industry recognized method of measuring voice call quality, Mean Opinion Score (MOS). The DSAM's MOS is an advanced algorithm that takes into account the human perceived quality of each call.
