Section 3
Using the 923LTS
This section describes using the Sage 923LTS to conduct local loop tests. See Section 1,
Getting Started for instructions about initial setup, charging the batteries, and loading test
software.
Test Steps in Brief
In brief, these are the steps to use the 923LTS in the field to test subscriber lines:
1. Turn on the 923LTS and select the desired test (or test suite).
2. Enter the phone number of the subscriber line.
3. If desired, enter your identification number and the order or trouble ticket number.
4. Using the supplied RJ-connectors cord, connect the 923LTS to the line.
5. Select the desired Sage 950RTS responder to call; testing begins automatically.
6. Review results, if desired.
Field Testing Prerequisites
The 923LTS is ready to perform tests in the field when:
•
the batteries are charged
•
responder phone numbers are stored or available for entry
•
test suites are available on the Sage 950RTS responder
•
if required, a service order number or trouble ticket number is available for entry
Connecting to the Line Under Test
In most cases, you connect the 923LTS to the line at the demarcation point or inside the
subscriber’s premises. Alternately, connect to the line at any two wire access point along
the circuit.
RJ Connections
Use the supplied cords to connect the 923LTS to
the line being tested (either the cord with RJ
connectors, or the cord with alligator clips). To
use the RJ connection cord:
1. Plug the RJ-48 (the larger end) into the
bottom of the 923LTS.
2. Plug the RJ-11 (the smaller end) into the customer’s connection.
Ground Connection
Connect the 923LTS to ground if:
•
the line being tested uses ground start signaling
•
a noise-to-ground measurement is part of the test sequence
