product introduction
ST332B ADSL2+ installation and maintenance tool is for all kinds of xDSL a much-needed (including ADSL, ADSL2, ADSL2+, READSL and other business)and the design of circuit test. The tester has the advantages of small volume,easy to carry, using liquid crystal display, menu operation, direct test results,excluding can easily xDSL the opening of business, maintenance and fault,greatly improve the operators xDSL broadband service level, is the best choice of first-line installation and maintenance personnel hand machine.
Two, product function and technique index
1, the test technology of xDSL index
When the connecting line is ADSL2+, meet the standards and testing DSLparameters are as follows:
1) meet the standards: ITU G.992.1 (G.dmt), ITU G.992.2 (G.lite), ITU G.994.1(G.hs), ANSI T1.413 issue #2, ITU G.992.5 (ADSL2+) Annex L. The maximumcommunication distance is 6.5km, the compatibility of ADSL and ADSL2, READSL and many other lines
2) transmission parameters can be DSL line test
Go on the DSL line / maximum descending rate;
Go DSL line upstream channel rate: 0 ~ 1.2Mbps;
Go DSL line downlink channel rate: 0 ~ 24Mbps;
Go on the DSL line / downlink attenuation: 0 ~ 63.5dB;
Go DSL line up / downstream noise margin: 0 ~ 32dB;
Go on the DSL line / downlink output power;
White CRC can be, FEC, HEC, NCD, LOS measure
White can display the connection mode DSL circuit connection well;
Determination of quality of service has to be.
Go can be a channel bit map display.
When the connecting line is ADSL, meet the standards and testing DSLparameters are as follows:
1) meet the standards: ITU G.992.1 (G.dmt), ITU G.992.2 (G.lite), ITU G.994.1(G.hs), ANSI T1.413 Issue # 2
2) transmission parameters can be DSL line test:
Go on the DSL line / maximum descending rate;
Go DSL line uplink channel rate: 0 ~ 1Mbps; \\
Go DSL line downlink channel rate: 0 ~ 8Mbps;
Go on the DSL line / downlink attenuation: 0 ~ 63.5dB;
Go DSL line up / downstream noise margin: 0 ~ 32dB;
Go on the DSL line / downlink output power;
Go for CRC, FEC, HEC, NCD, LOS measure
White can show DSL line connection mode;
Determination of quality of service has to be.
Go can be a channel bit map display.
2, dial test function
Fixed by PPP test account settings for users of twisted pair (WAN) PPP dial, andaccess to the end of the IP, IP, DNS server end of bureau of primary IP,secondary DNS server IP address to dial after the success of. Dial functionincluding PPPOA and PPPOE two models, in domestic is mainly used PPPOEmodel.
3, the Modem parameter setting function
Can be set up to the current Modem standard, selection of ADSL2 + or ADSLcompatibility mode, can be modified through the background management software or the dialing Properties button on the PPPoE PAP/CHAP and the username and password.
4, the function of Modem simulation
You can completely replace the user Modem, the user can put the test instrument as Modem to dial and the Internet, to verify that the user Modem problems.
5, the user data storage and browsing
The user data of the test with 50 groups of storage function, storage data transmission parameters, including line channel bit error test chart, preservation.And 50 groups of data of the saved according to different number of input with machine screen browsing.
6, electrical parameter test (DMM)
1) can be tested 400V~ DC voltage is 400V, the resolution can reach 0.1V
2) can measure AC voltage 0V~290V
3) can test line capacitance 0nF~1000nF
Accuracy: 0 10nF: + 2 nF 10nF-1000nF: + 2% + 2 nF
Measuring loop resistance of 0 ohm ~20k ohm
Precision: 0-100 + 3% + 4 100 - 500 500 - 2000 + 2% + 3%
2000 - 20K - 2%
Insulation resistance measurement circuit between 0M ohm to 50M ohm.
Accuracy: 0 - 1 + 0.1 M ohm: 1 - 30: + 10% + 0.5 M.
7, PING test function
But LAN and Wan PING test PING test. LAN PING test can determine whethersuccessfully connected to PING IP address, to confirm that the LAN is working properly. Wide area network PING test to wide area to office end networkdirection directly PING web site, check the WAN link connectivity.
8, call the function
The function of the realization of the common telephone function. Can call each other also can answer the call, can be in the test data, check the phone call.
9, the system parameter setting function
Can be set on the back light length, the longest time is 99S, the default time is15S by default, automatic shutdown time is 8 minutes, can also be set, automatic shutdown time length of 5 - 59 minutes setting, tone can be set to open or closed, the user name and password, VPI, VCI keyboard instrument modification,comparison ratio adjustment, work pattern of Modem modification, dialing modePPPoA and PPPoE mode selection, restore factory value etc..
