DIGITAL AND MEASURING SYSTEM "KROSS-M"
Registered in National Register for measuring devices, allowed to be used on the territory of Ukraine, # Ó 1344-00
- Automation of testing and measuring of all type subscriber and connecting line characteristics of city, rural and private automatic ATEs (Automatic Telephone Exchange).
- Measuring of telephone set (pulsed and tonal) parameters.
- Office virtual mini-ATE for connecting to 4 subscriber and local connection lines.
"KROSS-M" system complete set
- Measuring unit.
- Switching unit.
- PC (notebook).
Units operated through PC, RS232 interface type (modem interface for CRS (Centralized Re-pair Service)).
"KROSS-M" can be applied as:
- Automation equipped working place for telecommunication operators.
- Automated Repair Service creation on the base of "KROSS-M" measuring unit.
- Virtual mini-ATE for offices.
- Testing-and-measuring equipment for ATE.
"KROSS-M" system allows:
- Work with different types of ADS (Automatic Data Setting) and plug.
- Provide measuring for both individual and group of subscribers.
Determine the subscriber system state.
- Provide non-cleaning ADS dump.
- Measure voltage both to line and exchange between A-B wires, A-earth, B-earth (simultaneous displaying constant and variable component) together with analyzing of measuring result according to the standards. Range of measuring for direct voltage is 0,03-300 V with the error not more than 1%, and for alternating voltage with frequency from 20 to 200 Hz is 0,03-300 V with the error not more than 1,5%.
- Measure loop line, ringing currents (with simultaneous displaying of loop line capacity or resis-tance and analyzing the measuring result according to the standards). Ringing signal with frequency from 16 to 60 Hz is in the range of 0,06-100mA with the error is not more than 1,5%. Line loop cur-rent measuring error is no more than 1%.
- Measure exchange current in the range of 0,06-100mA, measurement errors is not more than 1%.
- Measure the telephone dialer current, measurement errors is not more than 1%.
- Measure resistance between A-B wires, A-earth, B-earth together with analyzing the measuring result according to the standards. In the range of 0,001-100kOhm the measurement errors is not more than 2%, in the range of 1-500kOhm the measurement errors is not more than 5%.
- Measure the capacity between A-B, A-earth, B-earth together with analyzing of measuring re-sult according to the standards. The range is 0,0001-10mkF with error not more than 2%.
- Measure incoming signal strength in the range of -30d- 0 dB with the 0,3-3,4 kHz frequency band and the error not more than 2,5%.
- Measure exchange answer signal in the range of -30d- 0 dB with the 0,3-3,4 kHz frequency band and the error not more than 2,5%.
- Measuring the psophometric noise mean square value in the range of 1-100mB with the error not more than 2,5%, peak factor = 3.
- Measure the parameters of the telephone dialer: periods (connect, disconnect, series) in the range of 50- 150 ms with the error not more than 2%, pulse coefficient with the error not more than 2,5%, the number of dialing pulse, disconnect current.
- Analyze and send DTMF signals.
- Send test tone signal to line in the range of -20 - 0 dB with the 0,3 kHz 0,3 kHz, 0,5 kHz, 0,8 kHz kHz, 1,5 kHz, 2,1 kHz, 3 kHz, 3,4 kHz, 40 kHz frequency band and the error not more than 2,5%.
- Dial the number to exchange.
- Send warning beep to the subscriber.
- Provide a voice communication with the subscriber.
- Operate in an automatic and semi-automatic mode, saving the measurement results in the data-base.
- Testing the four types of failures: "failure voltage", "short circuit", "low insulation", "line fault". Displaying of measurement results and analyzing of the collation with the ATE or the tele-phone line's standards and also with standard measures are also provided.
- Determinate the cable damage location up to rupture and SC, using measured.
- Measuring unit can work both as part of Centralized Repair Service under the Unix OS shell (connection with unit via modems) and as working place for telecommunication operator under the Windows software shell (connection with unit via COM port on RS 232).
- Some of the measuring can provide in real time with digital and graphical displaying of meas-urement results constantly and as well as in the program of test measuring once.
- Connecting to 4 subscribers and 4 local connection lines from operator's workplace.
- Addition to program for measuring is:
- card file of the subscribers for 2 exchanges by 10000 the subscribers. It is possible saving not only subscribers date but also standard measurement for each telephone line;
- receiving and keeping request in database (with writing out orders and statistical received re-quest);
- list of keeping the measurement results (its possible printing);
- archive closed failures;
- the subscribers list to request;
- cut number off lists.
- The device supports all the station types, but the most effective it is at the operation with ADS.
- Writing out information is comfortable for anyone user (digital, analog and in the form of prompting-generalization measurement results).
- The devise supply in a desired complete set is possible (separate measuring unit and switching unit and also automation equipped working place for telecommunication operators with PC).
