Welcome to an April issue of GL Communications' Newsletter providing information and insight into our products. We introduce our new Dual Universal Telephony Adapter (Dual UTA) - 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

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).

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

Important Applications:

• 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
