Announcing The TTC 2230: Tester Unites Physical Layer and Services Testing.

GERMANTOWN, Md.--(BUSINESS WIRE)--Sept. 22, 1998--

Expert 2M Instrument Offers WAN Transmission Analysis and

Troubleshooting In A Single Unit

TTC Tuesday announced the next generation of field testing with the TTC 2230 communications analyzer.

This is a rugged and easy-to-use instrument that offers one- touch physical layer testing and signaling analysis in a single lightweight, handheld platform. Ideally suited to the field technician dispatched to the customer premises, the TTC 2230's superior transmission-test capability helps get the job done right the first time.

The TTC 2230 gives field technicians the information they need to efficiently and accurately provision and install service. With ten modes of operation and summary statistics for BERT, voice, CAS and PRI ISDN, technicians gain insight into protocol-based problems without having to carry or operate a protocol analyzer.

Touch screen troubleshooting made possible by the TTC 2230 empowers the field technician with enhanced, software-assisted problem resolution without the complexity and overhead of a high-end analyzer.

"In introducing the TTC 2230, we offer 2M service providers investment protection as well as second-generation functionality," said Doug Smith, product line manager, TTC. "Based on the TTC 2000 Test Pad platform, the TTC 2230 sets a new standard for flexibility and future growth potential."

With call statistics and user-selected error event triggers, the TTC 2230 enables field technicians to reduce the number of service escalations, sectionalize and localize problems to maximize manpower, and perform accurate troubleshooting and sectionalization without an in- depth understanding of the underlying issues.

The TTC 2230 accomplishes a variety of tests and functions required when provisioning new service and maintaining or troubleshooting existing lines.

TTC understands field testing needs, offering more than 20 years of test equipment-design experience. The TTC 2230's mechanical enclosure is protected by a rubber overmold to absorb the impact of unexpected falls.

Also TTC has engineered a custom mounting to house the TTC 2230's VGA LCD and touch screen digitiser to protect against unavoidable impacts and mechanical twist. Every instrument is durability-tested to withstand heat, cold and vibrations. TTC guarantees the performance of the TTC 2230 with an industry-leading three-year warranty.

Available immediately, the TTC 2230 communications analyzer and options are priced from US$8,000 to $12,000.
