The SmartClass TPS is the ideal test tool to quickly place VoIP calls and verify QoS via mean opinion score (MOS) values.

A DSL, Ethernet TE, or WiFi interface allows testing VoIP anywhere in the access network, replacing either the DSL modem, VoIP phone, or both. The SmartClass TPS also includes an Auto Answer mode in which the unit automatically responds to an incoming call.

JDSU provides a wide range of signaling protocols including SIP, H.323, MGCP and SCCP, and voice decoding (G.711, G.722, G.723, G.726, and G.729).
