TSE In-House Testing Procedures
The TSE ISDN lab maintains state of the art equipment for testing and refurbishing, which includes provisioning for either National Standard or 5ESS Custom. The lab features computerized diagnostics for AT&T (Lucent) ISDN Telephones and the ability to setup and test "point-to-point" with local power, or complex "passive bus" arrangements with centralized bulk power. With over 500 components in stock and a computerized bar-code inventory system, TSE is ready to fill your next order.
The following information outlines The TSE Advantage:
Our 3 Point Testing Program
All telephone equipment is tested for functionality upon receipt at our warehouse facility.
At the final step of the refurbishing process, operational testing is performed.
At the packaging stage, all operations are verified and unit is wrapped and securely packaged for shipment.
Testing on Actual Telephone Lines
Other firms that use line simulators may miss defects that are present, as simulators are more tolerant of failures. For example, the 'D' channel is not tested on simulators that provide simple dial tone. Only actual telephone lines will use both 'B' channels and the single 'D' channel used by ISDN. Real world telephone lines installed at TSE, both National and 5ESS provisioning, will show any defect if one is present. This type of testing is designed to emulate the exact conditions under which our equipment will be operating, insuring you of a trouble-free installation.
Testing of Rack-Mounted Units
TSE has the capability of real world testing our NT1 termination racks and power supplies in our state-of-the-art lab. We are able to mount and thoroughly test the following equipment:
- P series NT1 circuit packs
- B and U series NT1 termination devices
- Bulk power supplies and battery backup equipment
These testing procedures for rack-mount equipment also use the TSE 5ESS and National actual telephone lines to accurately simulate the real-world environment.
Dedicated Data Computers
For customers who require ISDN telephone sets with built-in data capabilities, TSE offers data equipped models. These are thoroughly tested in our lab using dedicated data computers. These computers send data streams from one data telephone out onto actual real-world 5ESS or National phone lines and then back again to our facility, where the data stream is analyzed for faults and verified accurate. This procedure, while lengthy and rarely performed in the industry, insures the high quality standards for which TSE is known.
