Section 1 Introduction
The Sage Instruments 923LTS
The Sage 923LTS is the field component of the Sage Automated Local
Loop Test System (ALTS). The 923LTS initiates loop qualification and
benchmark tests between a subscriber site (or any two-wire access
point) and a Sage responder located with the telephone equipment at
the central office. The Sage 950RTS (or the Sage 356Eplus) performs
farend responder functions for the 923LTS.
The 923LTS is designed to be portable and durable, and can function
just like a telephone handset.
The 923LTS comes equipped to perform 100 and 102 test line
measurements, and performs Perceptual Speech Quality Measurement
(PSQM)tests.
Automated Local Loop Test System
(ALTS)
The Automated Local Loop Test System (ALTS) is designed to automatically test local
loops. Tests are useful to confirm proper line installation, and to monitor ongoing
performance.
ALTS has two components:
1. the Sage 923LTS hand-held unit used in the field
2. a Sage 950RTS (or 356Eplus) responder located in the central office.
A local subscriber can be served by a copper loop, a hybrid fiber coax loop, cable, or a
wireless loop. The 923LTS initiates tests, and displays results immediately upon
completion. Once a test is selected on the 923LTS, it runs automatically. Test templates
installed on the responder determine which tests the 923LTS performs, and each test’s
pass or fail criteria.
The Sage ALTS system can:
•Test transmission characteristics (e.g., loop voltage, ring voltage, call back
verification, connect time)
•Perform a 23 Tones test (e.g., attenuation distortion, 2-wire envelope delay distortion,
signal to noise, intermodulation distortion)
•Measure noise and delay (e.g., C-message, C-notched, absolute delay)
•Perform voice quality measurements (using PSQM)
•Perform 100 and 102 test line measurements
•Measure echo return loss

69100-0923-01 V2.0 SAGE INSTRUMENTS
Automated Local Loop Tests
The Sage 923LTS performs tests (individually or as part of a test suite) based on the test
templates supplied by the Sage responder. These local loop test suites may include the
following:
•Ring voltage and frequency
•3-Tone Gain Slope
•C-Measure Noise
•C-Notch Noise
•Return Loss
•3kHz Flat Noise
•Phase and Amplitude Jitter
•Impulse Noise and Hits and Droupouts
•23 Tones
•Level
•23 Tone Loss
•Envelope Delay Distortion
•Signal-to-Noise
•Signal-to-TotalDistortion
•IntermodulationDistortion
•Perceptual Speech Quality Measurement (PSQM)
Other Tests
The 923LTS may come equipped with other tests that do not require an ALTS responder.
They provide detailed results that can be viewed only on the 923LTS (i.e., results are not
collected in the ALTS database). Built-in tests may include:
100 Responder Noise Measurement
The 100 responder noise measurement operates with a type 100 quiet termination test
line.
102 Responder Loss Measurement
The 102 responder loss test operates with the type 100 milliwatt test line.
Perceptual Speech Quality Measurement (PSQM)
The built-in PSQM test operates with a Sage PSQM responder.

SAGE INSTRUMENTS 9100-0923-01 V2.0 7
The 923LTS Test Environment
Use the Sage 923LTS hand-held unit in the field to connect to the line being tested. The
Interface can be at a customer premises or at any two-wire access point. The 923LTS
can connect to customers served by:
•copper loop
•hybrid fiber coax loop
•wireless loop
Using menus on the 923LTS, the technician selects the test or test suite, and then
initiates a call to the farend responder (either the Sage 950RTS or 356Eplus). The Sage
responder contains instructions for the test sequence, and each test’s pass/fail
parameters. The selected test runs automatically. At the conclusion of the test, the
923LTS displays an immediate, overall pass/fail notification.
Using menus on the 923LTS, the technician can view the detailed results of each portion
of the test. During the test, the technician can listen to the dial tone, progress tones, and
other audible sounds. Typically, a test suite takes less than a minute to complete.
The 923LTS stores the results of the 10 most recent tests. Complete test data is stored
on the responder.
