HS-1T ADSL2+ Tester

The HS-1T ADSL2+ tester can not only test the physical layer parameters of ADSL2+/ADSL links but also perform alarm analysis on these parameters. It features a flexible keyboard input, allowing testers to easily modify parameters such as username, password, VPI/VCI, and alarm thresholds. With 7 built-in sets of VPI/VCI parameters and 7 sets of PPP dial-up connections, it meets the needs of different users without frequent configuration. The DMM test can measure line voltage, loop resistance, capacitance, and insulation parameters, and also estimate line length. It includes a modem simulation function and allows automatic shutdown time setting, making it suitable for various field installation and maintenance personnel!
HS-1T ADSL2+ Tester Product Features:
◆ xDSL Testing:
☆ View Parameters: Can test current upstream/downstream rates, maximum rates, line attenuation, noise margin, output power, and other physical layer parameters after connection.
☆ Set Thresholds: Allows setting parameter threshold values for alarm analysis of various physical layer parameters.
☆ Alarm Analysis: Performs data test alarm analysis based on set physical layer parameter thresholds and current test results, directly displaying OK or out-of-limit values. Also displays line capacity ratio.
◆ Bit Distribution:
☆ Graphical Display: Intuitively shows subchannel bit distribution graphically.
☆ Data Query: Allows querying each subchannel's number, frequency point, and allocated bit count individually via data query.
◆ Error Test:
Can test CRC, HEC, FEC, NCD, and OCD errors at both near and far ends after connection, with cumulative statistics for each error type.
◆ Record Browsing:
☆ Local Browsing: View saved test data directly on the tester by record number (supports up to 99 test records).
☆ Record Upload: Upload saved test records to a computer via RS232 serial port for unified archiving, analysis, viewing, and PC printing using backend management software.
☆ Record Clear: Clear all stored test records from the tester.
◆ DMM Testing(Optional):
Measures electrical parameters such as AC/DC voltage, loop resistance, capacitance, and insulation, with automatic line length estimation based on loop resistance and capacitance results. This optional feature can be added per user需求; models without this function are labeled HS-1S, with all other features identical.
◆ Dial-up Testing:
Uses built-in modem for PPPoE or PPPoA dial-up, allowing manual initiation/termination and querying of assigned IP information (local IP, peer IP, DNS1, DNS2). The tester supports round-robin dialing across 7 built-in VPI/VCI parameter sets, eliminating frequent changes for different central office tests, simulating PC+Modem functionality.
◆ Ping Testing:
☆ LAN Ping: Tests connectivity to PCs or devices within a LAN, verifying network connectivity. Allows modification of local IP and subnet mask for different LANs, overcoming limitations of fixed IP addresses.
☆ WAN Ping: Performs Ping tests over WAN after successful dial-up, supporting both IP address and domain name Ping. Includes predefined common domains (e.g., NetEase, Baidu) for convenience without repeated input.
All Ping tests allow configuring ICMP packet size, number of requests, and display resolved IP addresses, sent/received packet counts, packet loss percentage, etc.
☆ Local IP Management: Read or modify local IP address and subnet mask for LAN Ping testing.
◆ System Configuration:
☆ Priority Adaptation Standard: Set built-in modem to ADSL2+ auto-adapt or multi-mode priority for compatibility with various central offices.
☆ Authentication Management: Read or modify built-in dial-up account/password and authentication method (PAP/CHAP) locally or via backend software. Flexible keyboard input allows on-the-fly changes for validating user credentials.
☆ VPI/VCI Management: Read or modify 7 sets of VPI/VCI parameters locally or via backend software, reducing frequent configuration needs.
☆ Auto Shutdown Time: Set automatic shutdown time to suit different user requirements.
☆ Keypress Tone Setting: Enable or disable keypress tones for different environments.
◆ Line Voltage Indicator:
Lights up when DC voltage (>7V±1V) is detected, helping verify if xDSL lines with voice services are disconnected/crossed or if data lines have bound voice services.
◆ Others:
☆ Modem Simulation: Replaces user modems for testing in bridging or routing mode, visually verifying modem functionality.
☆ Backlight: LED backlit LCD with auto-off after 15 seconds of inactivity, suitable for day/night testing.
☆ Contrast: Adjust LCD contrast anytime during operation for optimal display visibility.
☆ DHCP Server: Built-in DHCP Server automatically configures IP addresses for PCs in the network.
◆ Backend Management Software:
Configures the tester, uploads test results, and performs archiving, analysis, and printing.
