Overview
The Dual Universal Telephony Adapter (Dual UTA) is a comprehensive hardware device designed to interface and test the voice and data quality
of telecommunication networks. The Dual UTA features all the circuitry necessary to universally adapt to any telephony instrumentation,
such as standard Plain Old Telephone Systems (POTS), digital hybrid interfaces, Voice over Internet Protocol (VoIP) networks, wireless
cellular phones and mobile radios including devices that utilize Bluetooth®, Broadband 3G/4G, LTE technologies.
As the name implies the Dual UTA contains a Side 1 and a Side 2. These sides are completely independent of each other so interfacing
with endpoints of a single network or interfacing with two completely separate networks are plausible scenarios.
Used in conjunction with GL's VQuad™ software application, the Dual UTA simplifies end-to-end testing of voice quality, echo, noise, and
other impairments of TDM, VoIP, and Wireless networks. A GPS sync port permits precise synchronization of sending and receiving audio functions,
one-way delay (OWD), and round trip delay (RTD). The Dual UTA can be directed to automatically send and record sample voice files between nodes of a
telephony network. These files can then be submitted to GL's Voice Quality Testing (VQT) software application for analysis according to widely
accepted International Telecommunications Union (ITU) voice comparison algorithms. These algorithms include PESQ, PAMS and PSQM.

VQuad™ with Dual UTA supports mobile audio interface for Smartphones (iPhone, Android, Blackberry) where the Dual UTA
acts as a headset connection to the Smartphone. Using Bluetooth® the VQuad™ can send a variety of commands to the Smartphone to
retrieve RSSI, Battery Level, and Network to name a few. VQuad™ can send commands to the Mobile Device Controller application residing on the
smart phones to remotely perform Automated Data Testing (NetTest) including TCP, UDP capacity, VoIP,
Route, HTTP, FTP, DNS and SMS irrespective of whether the phone is on a voice call or not.All results are retrieved by the Mobile Device Controller (MDC) and
sent to the WebViewer™ Central Database via DataImport.
VQuad™ with Dual UTA supports Fax Testing (sending and receiving) up to 4 independent and
simultaneous T.30 faxes. The user can configure the Tx and Rx fax rate from 2400 baud to 33600 baud with V.34 fully supported. Interfaces supported for
fax generation include 2-wire FXO and 4-wire analog. Support for additional interfaces such as T1/E1 and VoIP (T.38) are coming soon. Fax test results such
as messages, summary, errors are logged in VQuad™, which can be accessed via a simple WEB Browser/Viewer.

cord and handset
- Balanced I/O for connecting to a VoIP Softphone, Head and Torso Simulator (HATS), or any device supporting audio.
- Dual UTA 2-wire FXO or 4-wire analog interfaces supporting Fax testing
Applications
- Send/Record audio for Voice and Data Testing, Echo Measurements over TDM, VoIP, and Wireless networks
- Network One-way delay measurements. (collocated or geographically separated)
- Network Round Trip Delay (RTD) measurements. (collocated or geographically separated)
- Echo measurement and analysis using Echo Measurement Utility (EMU)

VQuad™ with Dual UTA (VQT270) supports Voice, Data, and Video Analysis Testing over Wired & Wireless Networks. Supported Data Test types
include TCP, UDP, VoIP, HTTP, FTP, DNS and SMS. The Data Tests are configured via the VQuad™ scripting and support the PC Ethernet connection
(wired, WiFi, Broadband 3G/4G) or mobile device. Using the optional GLs Mobile Device Controller application and the supporting downloadable apps on the
Smartphones (iPhone, Android), the VQuad™ can remotely perform the data tests when the phone is within a voice call or outside a voice call.

- Fax Emulation using VQuad™
VQuad™ using the Dual UTA 2-wire FXO or 4-wire analog interfaces can perform Fax testing (sending and receiving) up to 4 independent and
simultaneous T.30 faxes. The user can configure the Tx and Rx fax rate from 2400 baud to 33600 baud with V.34 fully supported. During testing fax (both
east and west) can be auto saved to PCM file for enhanced analysis using GL Insight and GL Fax Extractor. Support for additional interfaces such as T1/E1
and VoIP (T.38) are coming soon.
Screen Shot of Fax Messages, Summary, and Error Log
- Post Dial Delay (PDD) & Post Ringback Delay (PRD) measurements using GL's VQuad™ software
The analysis associated with the PDD detects the trailing edge of the last DTMF digit sent as part of the placed call.
It then detects the leading edge of the Ringback tone coming from the far end switch. The PDD is the measurement
between these two events.
The PRD measurement (coming soon) would be similar, however, it would detect from the end of the Ringback to
the beginning of the voice or end of the Ringback (beginning of the call). In other words, it would detect from the
end of the Ringback to the beginning of the call.
Both the analysis functions require the use of GL's 2-wire phone tap along with GL's VQuad™ software.
The VQuad™ scripts provide a mechanism to automate the required tone recording and analysis.

UTA Connections
Dual UTA Front Panel
1 - FXO Jack: This RJ-11 jack gives the Dual UTA the
ability to act as a telephone. This is a 2-Wire POTS interface that allows users to place calls, answer calls and utilize all
of the Dual UTAs voice quality and delay features.
2 - Push-to-Talk (PTT) LED: When illuminated indicates
that the PTT function is active. The active state indicates that the radio has been placed in transmit mode. Conversely,
the inactive state (LED off) indicates the radio is in receive mode.
3 - Trigger (TRG) LED: When illuminated indicates that
a Round-Trip Delay (RTD) or One-Way Delay (OWD) pulse has been detected. This LED may also illuminate momentarily
when connecting or disconnecting audio lines.
4 - In Jack: This 3.5 mm jack provides a balanced Audio
In port. This jack can connect to a wide variety of the network interfacing equipment. Multiple impedance options are
also available with this input.
5 - Out Jack: This 3.5 mm jack provides a balanced
Audio Out port. This jack can connect to a wide variety of the network interfacing equipment. Multiple impedance options
are also available with this output.
6 - Handset (HSET) Jack: For use with handset-type
phones. Connect the curly cord of the handset to this jack. This jack works in conjunction with the Handset (HSET) Base
jack on the back of the Dual UTA.
7 - Monitor Jack: This 3.5 mm jack (stereo miniature
phone type) provides for connection of a headset or amplified speakers to monitor the Audio In/Out signals on all
interfaces.
8 - Power LED: When illuminated indicates the Dual
UTA is receiving power and is ready to operate. The Dual UTA is powered from the USB bus.
9 - Side: The Dual UTA contains a Side 1 and Side 2.
These sides are completely independent of each other, so Mobile Phone Network Testing could be setup on Side 1
while FXO Network Testing could be happening on Side 2.
Dual UTA Back Panel
10 - GPS (In): Input from external GPS receiver. The
Dual UTA uses location and time to provide additional information to the user. The one pulse-per-second GPS input will
allow 1 ms accurate one-way and round-trip-delay measurements. Jack = RJ-45
11 - GPS (Out): The Dual UTA allows the GPS received
data on the GPS (In) port to be transmitted out the GPS (Out) port. This enables a single GPS receiver to provide data
to multiple Dual UTAs. Jack = RJ-45
12 - Handset (HSET) Base: RJ-22 port that connects
to a phone base on any telephone (POTS, VoIP, Digital) that contains a handset.
13 - Bluetooth (BT): The Dual UTA has Bluetooth
built in, which allows users to connect to Bluetooth enabled devices. This provides call control (control of phones
calling/answering functions) as well as the ability to send/record audio in/out of these devices.
14 - USB Jack: Communications and power interface
connection. Connect to the computer USB port directly or through a USB hub.
15 - Push-to-Talk (PTT): For use with radios that require
activation of a push-to-talk function to transmit or receive audio signals. This RJ-45 jack is connected to the
software-controlled relay internal to the Dual UTA. When PTT is active (PTT LED on), pins 4 & 7 are shorted.
