Dual VF Tx Rx - Analog
with tProbe™ Analyzer
Latest T1 E1 Software Ver 11.1.17 is Now Available | Download Now!
Dual VF TxRx (w/tProbe™ only) application is included with T1 E1 Basic Software
The Dual VF Tx Rx (earlier called as Simplified Audio Client) application is designed exclusively to perform non-intrusive and intrusive VF audio monitoring, VF audio recording, and testing easily. Dual VF Tx Rx provides an alternate & simple GUI similar to the basic applications in T1 E1 Analyzer software to perform analog Tx/Rx functions. SS1 Analyzer and SS1 Dialer applications
also have been enhanced to operate in conjunction with the Dual VF Tx Rx and its modules.
Now, Dual VF Tx Rx is available as a part of T1/E1 analyzer basic applications.
Dual VF Tx Rx supports Analog operational mode featuring two VF interfaces per unit, with each VF interface providing independent Tx/Rx functionality.
- Mode 1: VF1 (Tx/Rx) and VF2 (Tx/Rx)
- Mode 2: VF Tx and VF Rx
The application supports Spectral displays, which can be observed for both Tx/Rx directions. Analog signal can also be listened using the inbuilt speaker
inside the tProbe™ unit or using stereo headphones if the environment is too noisy.
VF monitor and record functions can be performed simultaneously using appropriate modes. The recording is independently and simultaneously made for
both directions. The files are recorded in mu-law format for both directions and can later be analyzed using Goldwave software. Only one direction can also
be monitored and recorded on the relevant port.
Additional future enhancements of Dual VF Tx Rx include support for SS7 traffic, Ethernet traffic, digital interface support including BERT, noise measuring
(gains/ hits/ dropouts), voice/noise capture to file & playback from file, Digits captured to file and other capabilities.

Analog Interface Configuration
Configuration pane is available with the default board configuration parameters. Board Type option allows SAC to automatically connect to the T1/E1
devices when invoked, displaying the board in use. Audio traffic and files can be saved to the directory used for transmit and receive traffic. The tone threshold
value for Tone detection can be set up to 80 dBm.

VF Tx / Rx Actions
In VF Tx /Rx operational mode, TX/Rx functions are supported on a single VF port (either VF1 or VF2). The sending and receiving traffic functions such as
Tones, Digits, and Files are possible.
Transmit Tones option is used to send user-defined single/ dual Frequency tones on VF ports (VF1/VF2). Generate Tone 1 low frequency
component listed from lowest to highest. If a monotone is transmitted, the tone frequency is set here. Tone 2 a high frequency component. If a monotone
is transmitted, Tone 2 is set to zero. Detect Tones on selected VF port viewing the status and the spectral display.
Transmit Digits option used to generate DTMF/MF digits on VF ports (VF1/VF2) with defined On/Off time (ms) and Power (dBm). Support to
Detect DTMF, MF digits on selected VF port.
Send Voice File option is used to send GL proprietary voice files of type PCM on VF ports (VF1/VF2) and record voice files (*.pcm) on selected VF
VF Tone, Digits, Files Tx/Rx Actions
VF1 and VF2 (Tx / Rx) Actions
In VF 1/VF 2 operational mode for each VF interface supports independent Tx/Rx between VF1 (Tx/Rx) and VF2 (Tx/Rx) simultaneously. The transmit actions
on one VF port will be received on another VF port. The sending and receiving traffic functions such as Tones, Digits, and Files are possible.
The VF Tx/Rx Tones, Digits, and Files status and the spectral can be viewed for sending VF ports in the VF Status and Spectral Display.
VF 1 and VF 2 Transmit and Receive Actions
VF Status and Spectral Display
The Side panels display
- Tx/ Rx status for the tone, digits, voice transmitted/received on any particular VF port.
- Frequency, Power count status of the VF In and Out
- Data transmitted or received on a specified VF port graphically (spectral Power (dBm) Vs Frequency (Hz))
- Sending/Receiving Speakers for Tx/Rx ports
- Multiple impedance options for audio In and Out ports
VF Status and Spectral Display
SS1 Emulator and Analyzer
SAC is enhanced to invoke SS1 analysis and emulation applications from within the GUI. The SS1 Dialing Digits (Dialer) and SS1 Analyzer applications
provides the ability to dial and analyze tone sequences that make up SS1 dial digits. The SS1 Emulator includes options to setup Dial Code with control
mask & space frequencies and duration, and other parameters related to the digit dialer. Users can create channel for Transmission (Tx), choosing Port
Using SS1 Analyzer sequences of pulse and guard tones are detected, decoded, and assembled into their corresponding dial digits. The tone sequences
are also verified for compliance against a “specification” parameter file which can correspond to published standards or user criteria.
Refer to SS1 Signaling Emulator and SS1 Analyzer webpage for details.
SS1 Simulation (Dialer)
Dual VF Tx Rx includes Goldwave capabilities to view and analyze send and receive audio files. Any chosen mono and stereo (east and west) files in supporting file
formats (*.pcm, A-Law, Mu-Law, *.wav, and others) that have been recorded can be viewed, heard, and analyzed using Goldwave.
Refer to Goldwave webpage doe comprehensive details on record or playback capabilities using Goldwave application.

Please Note: The XX in the Item No. refers to the hardware platform, listed at the bottom of the Buyer's Guide, which
the software will be running on. Therefore, XX can either be ETA or EEA (Octal/Quad Boards), PTA or PEA (tProbe Units),
UTA or UEA (USB Units), HUT or HUE (Universal Cards), and HDT or HDE (HD cards) depending upon the hardware.
