Telepath 550B+ ISDN Test Set
Full array of features, functions, and performance capabilities with considerable built-in flexibility to turn-up and troubleshoot Basic Rate ISDN (BRI), EBS (P-Phone), and POTS, and supports all U.S. call controls and ISDN central office switches.
Features
- Intelligent Testing Features - Local / Distant bearer capability tests quickly confirm that calls can be placed to the local switch and to a distant subscriber using four different bearer capabilities
- Pinpoint ISDN Problems
- Auto SPID feature reports and displays the SPIDs, allowing you to select the correct SPID for testing
- SPID Guess determines the SPID after the 10-digit directory number has been entered
- Built for Today's Technology - Auto Video Test auto-answers and loops both B channels for video calls
- User-Friendly Design - Technicians with limited training can do the job quickly and correctly in the shortest possible time
- Tests Anywhere - Compact, lightweight and weather-resistant
Applications
- Verify customer services for Voice, Data, and Packet ( B and D channel ) services
- Determine line quality with BER testing ( via pre-qualification with LT / NT Emulation Mode )
- Provide dual call support, including dual channel BERT and inter-channel delay testing to make the TPI 550B+ particularly useful in multimedia applications such as video conferencing
- Troubleshooting U and S / T Interface Testing
- U-Monitoring capability - An optional U-Monitor interface allows bi-directional monitoring of in-service D-channel signaling messages with storage, on screen LCD display, or RS-232 data port output
- 2-Wire Interface capability - The TPI 550B+ can test the ISDN network at the 2-wire U interface using 2B1Q line coding and at the 4-wire S/T interface. Testing at these interfaces can include margin analysis using selectable dB Loss Pads. LEDs indicate vital information for each interface, including Sync, Active, and Ready status
- Emulation capability - Because the TPI 550B+ can emulate the NT1 or the TE (i.e., an ISDN phone), or a combination of the two ( NT1 / TE ), it is capable of testing these elements in isolation - an important problem solving feature
