Sunrise Introduces Network Diagnostic Tools 

January 2, 2002 -- Sunrise Telecom Incorporated (Nasdaq: SRTI), a provider of service verification equipment for telecommunications and Internet networks, announced a series of next-generation Internet Access Network diagnostic tools designed to provide a complete solution for Internet protocol troubleshooting. These new features provide thorough testing for both ATM and IP protocols, used by both Internet Service Providers (ISPs) and Network Service Providers (NSPs) as the basis for Internet service delivered to DSL customers.

Together these new features should allow telephone companies to better serve their customers and eliminate wasted diagnostic time by quickly pinpointing the source of service-affecting issues in the telco-owned Internet access network from DSL modem to ISP hand-off. These new tools are available in several ADSL test modules compatible with SunSet xDSL test sets. The wide selection of test modules provides the highest level of compatibility with the large variety of DSLAM chipsets currently in use.

The new Internet Access Network diagnostic tools are:
-- ATM OAM Cell Response
-- ATM OAM Cell Generation
-- ATM VCC Scan
-- IP Session and Fault Analysis
-- IP Trace Route
-- IP Echo Response
-- ADSL / ATM DSLAM Verification
-- Asymmetrical ATM BERT
-- DSLAM Bulk Provisioning Macro

The OAM Cell Response feature allows a SunSet xDSL operating from the customer location to respond to F4 or F5 ATM OAM test cells generated from a DSLAM, ATM Switch, or an ISP's Broadband Remote Access Server (B-RAS). The OAM Cell Generation feature allows the test set to generate these same cells in order to diagnose faulty network elements, connections, and provisioning. A VCC scan feature simplifies VPI/VCI identification issues, saving the technician valuable time.

The IP Package software now includes Session and Fault Analysis to help troubleshoot ISP connectivity problems. Technicians receive data identifying non-responding routers and detailing bad user names and passwords. The Trace Route feature quantifies the number of hops in the network path, while the Echo Response feature verifies two-way connectivity between the customer and the ISP.

Perhaps the most significant development is the Two-Ended ADSL / ATM test feature for DSLAM installation and provisioning utilizing a SunSet xDSL and a SunSet OCx or SunSet SDH on each side of the DSLAM. This feature, originally developed for installation of remote DSLAMs, utilizes a proprietary, automatic detection tool allowing an OCx or SDH to identify the VCI/VPI circuit values on the optical side and to detect ATM cells generated by the SunSet xDSL. In addition to verifying correct cross-connection, an advanced, Asymmetrical BERT feature verifies SLA provisioning across the DSLAM at both downstream and upstream data rates. A new DSLAM Bulk Provisioning test macro helps prevent problems before they occur by verifying proper DSLAM provisioning.

DSL customers continue to demand high-quality service from their service providers, even though network problems may not be their fault. These new ATM and IP tools from Sunrise Telecom may allow service providers to be responsive to the customer and proactive in finding a solution, even when the fault lies with a third party network provider.
