Ⅰ. Overview The ST360B-AT is an advanced, mature and professional Triple Play Tester, which will not be replaced today and tomorrow. This tester not only has useful xDSL data test function but also can test the network transmission quality of video stream (jitter, package loss, transmission speed, MD IDF delay), Voice (VoIP testing supporting SIP). Consequently, it becomes the best choice for xDSL, IPTV, VOIP service confirmation testing, maintenance and troubleshooting Ⅱ. Key Features ◆ 240*320 TFT liquid crystal big touch screen, can be clearly seen under the light. ◆ Embedded operating system, friendly operating interface ◆ 200M bytes of storage space can storage test records and exchange test data by U disk ◆ The result is direct-viewing ◆ Powerful DSL test functions ◆ Makes determining IPTV and VoIP quality fast Ⅲ. Main Functions ◆ DSL Test xDSL test Physical layer test PPPoE dial and PPPoE dial properties revise Network layer test (Ping, Ipconfig, Tracert and Route) Webpage browse function LAN test LAN port PPPoE Dial and properties revise function Network layer test (Ping, Ipconfig, Tracert and Route) Fixative IP scanning function Webpage browsing function Modem emulation ◆ IPTV Test IPTV test configuration Mostly are settings of multicast addresses and several threshold values. Settings of multicast addresses should be in the multicast testing circumstance. Set top box (STB) emulation test in the multicast environment can be made after the success setting of testing items or multicast addresses. IPTV initialization test Test possible malfunctions during the process of IPTV initialization. Include: Line fault, Modem fault, STB fault, PPPoE dial fault, IPTV operation authentication and EPG obtain fault etc. IPTV video stream detect It can detect transmission video streaming automatically, display the video stream encapsulation format and net configuration parameter after the IPTV operation initialization. IPTV test parameters ◆Transmit quality and test parameter 1. IP package number 2. TS package number 3. Video package number 4. Audio package number 5. IP package jitter 6. IP package loss 7. Transmission speed of IP package 8. Video transmission speed 9. Audio transmission speed 10. PCR jitter ◆Code stream quality ◆Net configuration MODEM emulation Records browse File management ◆VOIP Test Provide VOIP service test function, show and save test result. VOIP Setting Config setting items before VOIP test. Main items are parameters setting and threshold setting. VOIP Test VOIP test function, show and save test result.
