Turnstone Solution Now Supports Fast, Accurate DSL Pre-qualification

Apr 10, 2001, 01:00 ET from Turnstone Systems, Inc.

    DSLcon Spring 2001, DENVER, April 10 /PRNewswire/ --
 Turnstone Systems (Nasdaq:   TSTN) announced today that its Copper
 CrossConnect(R) CX100 can now pre-qualify all local loops terminating on a
 Class 5 voice switch to determine each loop's suitability to support digital
 subscriber line (DSL) service. The Copper CrossConnect CX100's new features
 enable providers of residential DSL services to store loop pre-qualification
 information in a database for reponding quickly and accurately to customer
 inquiries for DSL service or for facilitating targeted marketing campaigns.

     Turnstone's Copper CrossConnect CX100 and other solutions are being
 demonstrated in Booth 623 at DSLcon Spring 2001, which continues through
 April 12 at Denver's Colorado Convention Center.
     DSL service providers typically rely on historical engineering records or
 distance estimates generated by mapping software to pre-qualify local loops
 for DSL services. Frequently, this methodology yields inaccurate results
 causing increased operational costs and customer frustration when the promised
 service doesn't work. Also, inaccurate loop records can lead to missed revenue
 opportunities when qualified loops are incorrectly determined to be
 unsuitable. Turnstone's automated solution can take the guesswork out of DSL
 pre-qualification.
     The Copper CrossConnect CX100 can now connect to a Class 5 voice switch to
 access and test all loops terminating on the voice switch to accurately
 determine loop length, presence of load coils, AC and DC loop characteristics
 and narrow-band noise for each loop. The system analyzes test results,
 indicates which DSL services are suitable for each loop and infers probable
 loop faults. The information can be stored for access via a Web interface with
 Turnstone's CrossWorks(TM) Back Office Automation Software, or the information
 can be integrated with operational support systems (OSSs) for flow-through
 pre-qualification when the CrossWorks Application Programming Interface (API)
 Server is deployed. Automated pre-qualification can be performed regularly to
 ensure that information is fresh. Testing can also be performed on-demand for
 real-time loop pre-qualification.
     "Accurate pre-qualification information is key to service providers
 scaling their DSL business." said Patrick Hurley, DSL analyst with TeleChoice,
 Inc., a telecommunications management consultancy that works closely with
 leading broadband players and releases DSL-deployment statistics quarterly.
 "Accurate pre-qualification minimizes deployment delays and extra
 troubleshooting truck rolls that are caused when DSL is deployed on loops that
 are unsuitable for service. Deploying DSL on qualified loops allows service
 providers to turn up more customers more quickly. It also ensures service
 providers don't decline business -- and miss revenue -- on qualified loops."
     "Turnstone recognizes that loop management must go beyond reactive testing
 to provide proactive solutions that facilitate efficient loop management
 throughout the DSL lifecycle, including loop-management solutions that
 facilitate order processing and provisioning," said Eric Andrews, vice
 president of marketing with Turnstone. "Our pre-qualification solution
 demonstrates our commitment to providing a comprehensive solution that helps
 service providers rapidly deploy and efficiently maintain DSL networks."
     Turnstone's pre-qualification solution is available for trials and will be
 generally available in June.
