Sage instruments 923LTS hand-held field tester
Using the 23-tone test as defined in IEEE Standard 743-1995, the system rapidly profiles the transmission characteristics of the local loop. Measurements are compared to a user-defined template containing the acceptable limits. The technician then recieves an immediate PASS or FAIL indication at the subscriber's site.
In addition, the ALTS system can perform PSQM measurements for VoIP voice quality testing, plus a complete test of AC/DC loop parameters, including Loop Current, Voltage, Ring Voltage, and Dial Tone Delay. ALTS also supports automatic execution of classic transmission impairments tests such as Noise, Absolute Delay, Return Loss, Impulse Noise, and Phase and Amplitude Jitter All tests can employ user-defined PASS/FAIL limits.
