The Latest in Portable Intelligent Testing

Technicians require an easy-to-use portable test set to handle the job the first time out. This is why they choose JDSU/Acterna's TPI 550B+ to validate their internal communications networks.


  • Local/Distant bearer capability tests which quickly confirm that calls can be placed to the local switch and to a distant subscriber using four different bearer capabilities.
  • One of the 550 differentiators is the ability to perform an inter-B channel delay measurement, display the results, then run dual BERT at 64K, to assure videoconferencing success.
  • Other new enhancements are G.821 in BERT, more BERT patterns, and 3.1K audio bearer capabilities.
  • Additional enhancements include test macros, parameter download, AutoSPID, and IDSL testing.
  • Verifies customer services for Voice, Data, and Packet (B and D Channel) services.
  • Determines line quality with BER testing (prequalification with LT/NT Emulation Mode).
  • Tests 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.
  • 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.
  • Emulates the NT1 or the TE (i.e., an ISDN phone), or a combination of the two (NT1/TE). Is also capable of testing these elements in isolation - an important problem-solving feature.
  • Pinpoint ISDN problems with Auto SPID. This 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 128K video calls.
  • User-friendly design allows technicians with limited training to do the job quickly and correctly in the shortest possible time.
  • Compact, lightweight and weather-resistant, the TPI 550B+ goes wherever your testing needs take you.
