Keysight Technologies Inc. has released support for the latest 3GPP Enhanced Voice Services (EVS) codec with the Keysight E6966B IMS-SIP network emulator software. The company also improved its UXM wireless test set with more IMS/VoLTE controls in its LTE/LTE-A test application software that includes front panel user interface configuration of 1) traffic flow template (TFT); 2) dedicated bearer setup; and 3) end-to-end VoLTE testing with two UEs connected to a single UXM.

Keysight has updated the E6966B software, which emulates the P-CSCF and IMS core network, with many a number features, including the EVS option E6966B-5TP.


The Keysight EVS E6966B-5TP option includes: all bit rates from narrowband 9.6Kbit/s to super-wideband 128Kbit/s, as well as fixed rate; rate change modes such as priority, peer requested and stress, which enables the user to change the bit rate automatically every 20ms; and primary mode and AMR-WB IO compatibility mode.

The E6966B IMS-SIP network emulator software includes the client and server, enabling the user to test either in a PC-only soft client configuration, or integrated with the Keysight E7515A UXM wireless test set to emulate the entire IMS/VoLTE environment for end-to-end IMS/VoLTE test.

Complementing the UXM wireless test set and E6966B IMS-SIP network emulator software, the Keysight U8903B performance audio analyser provides pre-configured perceptual evaluation of speech quality (PESQ) and perceptual objective listening quality assessment (PoLQA) audio measurement analysis to complete the voice quality test solution.
