Press Release: GL Announces Dual UTA
Gaithersburg, Maryland, USA - May 7, 2009 - GL Communications Inc., announced today the release of their new
Dual Universal Telephony Adapter (Dual UTA) product. Announcing the news to the press,
Mr. Matt Yost, Manager at GL said, " Our new Dual UTA is a versatile hardware/software device designed to interface to a variety of
subscriber units including: 2-wire Analog Phones, Mobile Phones, Bluetooth™ Phones/Devices, Military Radios, VoIP phones, and 4-wire handsets".
He added, ‘Used in conjunction with GL's VQuad™ software, 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) ".
Mr. Yost further added, "The Dual UTA as the name implies provides two sides with identical functionality: Side 1 and 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 practical scenarios".
The unit provides the following hardware interfaces:
- Mobile Phones
- Bluetooth™ - Works with all Bluetooth™ phones for both call control and send/record audio functions
- Audio Headset Jack - 2.5mm (typical)
- Mobile Radios with Push-to-Talk functionality: Provides radio keying and sends/records audio
- RJ-11 POTS lines: Detect dial tone, go off hook, CallerID detection, send digits (two stage dialing), answer calls, detect a variety of Special
Information Tones (SIT), and much more as well as send/record audio for Voice Quality measurement
- Handset Phones: Replaces handset of any telephone (POTS, Digital, VoIP) that contains a coiled cord and handset
- Balanced I/O for connecting to a VoIP Softphone, Head and Torso Simulator (HATS), or any device supporting audio. Send/Record audio for
Voice Quality measurements
- Send/Record audio for Voice Quality Testing on all telecom networks including WideBand 16k Samples/sec
- One-way delay (OWD) measurements - collocated or geographically separated
- Network Round Trip Delay (RTD) measurements - collocated or geographically separated
- Echo measurement and analysis
- Acoustic echo canceller testing
- Automatic control of Push-to-talk phones/radios - key/unkey radio
