960B Multi-Channel Test Instrument

Powerful multi-channel IP telephony testing

Talk to us about this

The 960B is a powerful multi-channel IP Telephony precision test instrument combining TDM, Ethernet and Analog interfaces and simultaneous test capability to comprehensively test and monitor Next Generation Networks in Real-Time.

The 960B can generate one or many end-to-end test calls from the packet, TDM, and/or Analog interfaces while monitoring the bearer channel (TDM, RTP, Analog) to flush out real-time performance issues.
