Overview
The Sage 925VST
The Sage 925VST is the field component of the Sage Voice over Packet Test System
(VTS). The 925VST initiates VoP service qualification and maintenance tests from a
customer premise or any 2-wire or 4-wire access point to a Sage responder that is typically
located in the central office. The Sage responder performs the cooperative farend
responder test functions and sends the measurement data back to the 925VST for review,
processing (pass/fail), and storage. The 925VST is designed to be portable and durable
and can function just like a telephone handset.
The 925VST initiates tests and displays results immediately upon completion. Once a test
is selected on the 925VST, it runs automatically. Test criteria templates installed on the
925VST determine whether a test passes or fails.
The 925VST comes equipped with the Sage Next Generation VoP Test suite. Including
SMOS, Packet Voice Impairment Test (PVIT), Echo Sounder, DVM, DTMF, and
Callback tests. In addition, the 925VST supports legacy 100 and 102 test line
measurements. Additional options include
• 2-wire analog interface
• 4-wire analog interface
• responder mode
• fax text
VoP Test System (VTS)
The 925VST and farend responder are designed to qualify VoP service installations and
support on-site field maintenance. Tests are useful to confirm proper lAD (Integrated
Access Device) installation, softswitch DN translation, end-to-end voice quality, and
detect and isolate echo, packet impairments, and poor network performance.
VoP Test System has two components:
• The Sage 925VST hand-held unit used in the field
• A Sage farend responder that can be located at any telephony 2-wire, 4-wire, or T1/E1
termination point.

Other Tests
Other TestsOther Tests
Other Tests
The 925VST may come equipped with other tests that do not require a Sage farend
responder or that enable the 925VST to emulate a farend responder. They provide
detailed results that can be viewed only on the 925VST. These 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.
• Fax Emulator Test
The Fax emulator test operates with a standard facsimile machine
• SMOS Test Line
• Packet Voice Impairment Test (PVIT) Send Test Line
• Echo Generator Test Line

The 925VST Test Environment
Use the Sage 925VST hand-held unit in the field to connect to the voice line being tested.
The interface can be at a customer premises or at any 2-wire or 4-wire access point. The
925VST can connect to customers served by:
• copper loop
• hybrid fiber coax loop
• wireless loop
• IP
• digital PBX
Using menus on the 925VST, the technician selects the test and then initiates a call to the
Sage farend responder (either the Sage 94xRTS, 950RTS, 935AT, 930i, 925VST, or
325EV). The selected test runs automatically. The 925VST retains pass/fail parameters for

each test. At the conclusion of the test, the 925VST displays an immediate result and
pass/fail notification if pass/fail template is enabled.
Using menus on the 925VST, the technician can view stored 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 takes less than 30 seconds to complete.

Initial Charge
Initial ChargeInitial Charge
Initial Charge
The 925VST comes with rechargeable batteries
installed at the factory. Before using the
925VST for the first time, charge the batteries
for two hours.
Do not turn on the 925VST while the batteries
charge for the first time.
1. Make sure the 925VST is off (i.e., the display is blank and dark).
2. Plug the AC adapter power cord into the appropriate AC outlet.
3. Plug the cord from the AC adapter into the power port on the bottom of the
925VST. Leave the power cord plugged in for at least two hours to allow the
batteries to fully charge.
