  • Verifies customer services for Voice, Data, and Packet (B and D Channel) services
  • Determines line quality with BER testing (pre-qualification 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 insolation - an important problem-solving feature
