T1 Module to debut at Supercomm in Atlanta, GA, June 4-6, 2002,

booth #24128

Sunrise Telecom Incorporated (Nasdaq:SRTI), a leading provider of service verification equipment for telecommunications, cable TV, and Internet networks, introduces the T1 Module for the SunSet MTT and xDSL modular test set platforms, marking the industry's most cost effective solution for T1 testing.

In addition to basic T1 Bit Error Rate Testing (BERT), the T1 Module offers advanced capabilities including VF Level Testing, HDSL Span Control, CSU/NIU Emulation and Control, as well as Pulse Mask Analysis. At $1,295, this new module provides the best ratio of features-to-price for a low cost T1 test set, yet offers a future proof solution as testing requirements change or grow. With 24 modules now shipping for the SunSet MTT and xDSL platforms, the flexibility of adding additional test modules in the field allow for the initial investment to be upgraded to address the growing testing needs of field technicians.

The SunSet MTT and xDSL platforms give access network technicians the industry's broadest selection of testing options needed to install, verify, and troubleshoot a wide variety of service technologies including T1, ISDN BRI, Voice Frequency (VF) Transmission, Datacom, DDS, IP, Gigabit Ethernet, ADSL, IDSL, SHDSL, and HDSL2. Because each module has a similar user interface and menu structure, the learning curve for technicians is faster than for separate standalone products for different technologies with different interfaces. As testing requirements shift to new services, the SunSet MTT and xDSL test sets will provide the technician with a modular tool powerful and versatile enough to adapt to new technologies.
