Ando ADSL-7000

The Ando ADSL-7000 is a network testing instrument for comprehensive analysis and troubleshooting of ADSL and ADSL2+ services. It delivers detailed physical layer diagnostics, copper line qualification, IP connectivity verification, and IPTV stream assessment in a single platform. Engineers use it to validate service delivery, isolate CPE faults, and ensure line performance meets contractual thresholds across multiple protocol standards and transport modes.

– Technical Specifications

The unit supports ITU-T G.992.1 (G.DMT), G.992.2 (G.Lite), ADSL2 (G.992.3), and ADSL2+ (G.992.5), along with ANSI T1.413-1998 Issue 2. Protocol stack includes ATM OAM F4/F5, PPP, Static and Dynamic IP, DNS, IP PING, TRACERT, HTTP, FTP, IGMPv2, and MPEG2-TS Broadcast via UDP/RTP.

– Key Features

ADSL Analysis: Graphical bits-per-tone and SNR-per-tone display, actual and maximum bit rates (upstream and downstream), utilization rates (upstream and downstream), transmit power (upstream and downstream), line attenuation (upstream and downstream), and SNR Margin (upstream and downstream).

Copper Testing (CableCheck): Longitudinal balance, capacitance, DVOM, distance-to-short, leakage, opens detection, and loadcoil counter with pass/fail indication and programmable thresholds for ADSL2+ service qualification.

IP Connectivity: WAN and LAN PING testing with TX/RX statistics, delay measurement, and TRACERT functionality. HTTP and FTP URL/file testing supported.

Error Analysis: LOS, LOF, Reed-Solomon FEC (INTL), and CRC anomalies (FAST and INTL, optional).

IPTV Testing: STB emulation, QoS testing, TS PCR Jitter, video stream data rates, total IP packet RX count, and PID analysis.

Through Modes: ADSL Through mode for simultaneous DSL and IPTV analysis, Bridged Ethernet, Ethernet TE mode for CPE isolation, and modem replacement capability.

Performance Metrics: Fast bit rates, Interleaved bit rate (INTL), maximum bit rate, utilization rate, transmit power, line attenuation, SNR Margin, TS PCR Jitter, and IP packet counts (upstream and downstream where applicable).

Alarming: Downstream channel threshold and SNR Margin threshold monitoring.

– Typical Applications

Broadband service validation, line qualification, customer premises equipment troubleshooting, IPTV stream quality assessment, and copper plant characterization.

– Compatibility & Integration

DMM (Digital Measurement Module) support extends measurement capability. Ethernet statistics (RX/TX bytes) and ATM statistics (OAM F4/5 near and far loopback counts) enable multi-layer network diagnostics.
