VB Client for Client Server Software
GL's VB Client is a Windows based GUI Client application that communicates with the GL's Server Software to execute and
display basic functions on T1 and E1 lines. The VB Client application can be invoked as a stand-alone Client or in the case when
it is co-resident with GL's T1/E1 analyzer cards, from the special application drop down menu --> WCS VB client. GL can provide
free assistance in developing additional capability in the VB Client or GL Server.

VB Client includes the following functionalities:
- Capture Tones/Digits:
VB client's Capture Tones/Digits application is used to capture tones and identify
special tones (DTMF, MF and others) on a single timeslot.

You can select the Port and Timeslot on which the tone has to be captured. The Start Monitoring button is enabled the real-time tone
All of the tones captured are listed in the display area of the window. Clear History window deletes the records listed in this area.
Task monitoring will continue until the application is exited or the Stop Monitoring button is enabled.
Any previously saved text file containing captured tone information can be selected for monitoring. For real time capture tone
monitoring, tone is transmitted using 'Transmit Tone' application of T1/E1 and tones being captured are monitored in WCS Vb Client
- Real-time MFC-R2 Analysis:
VB client's MFC-R2 Analysis application is used to analyze R2 signaling on
E1 trunks and R1 signaling on T1 trunks in real-time.

Select port from Port Selection drop down box and timeslot from Timeslot selection scroll button for real-time capture. These
(ports) are represented as east and west trunk for PCM data capture. The selection of R2 for E1 and R1 for T1 is through a drop
down box labeled Tone Recognition Type.
The signaling capture display area has ABCD signaling and PCM data labeled columns for east and west trunks. Further, the
Time of capture and the Comments for various captured events of R2 & R1 are labeled with separate column heads.
Any previously saved text file containing R2/R1 signaling can be used for off-line analysis.
- Facility Data Link (FDL) Rx/Tx Utility:
This can be invoked by selecting FDL Tx/Rx from the Special Applications menu. FDL utility can simulate and decode
FDL messages. These messages (in the real network) are used to check
whether degradation exists in the network or in the CI (Customer Installations) or in both.
Screen Shot of FDL Utility PRM
This window consists of four parts:
- Transmit a Codeword or PRM.
- Performance Report Messages.
- History window.
- Received FDL.
Transmit a Codeword or PRM:
This can be used for the transmission of all FDL messages. The mode of transmission depends upon the user requirement.
Following are the modes of transmitting the FDL messages:
- One shot: Messages will be sent once.
- Two shot: Messages will be sent twice at a time.
- Tx Continuously: Messages will be sent continuously.
NOTE: Mode of transmission is restricted for code words and for text messages.
Performance Report Message
This section deals with the transmission of the following FDL messages

History: Which depicts Time (with date and time) column, Tx/Rx (indicates message sent or received) column, Action
(Indicates which type of message has been sent or received) column, Transmitted Hex (Action associated hex will be displayed)
column, Comment (Displays which type codeword has been sent or received) column. The details available in the history can be
saved as text file (.txt) and can be loaded later for analysis. Checking "log out-put" under option menu, automatically can save
sent and received messages.

Received FDL: This section consists of Monitoring alarms and Statistics part. Monitoring of all PRMs will indicate the errors
received from various PRMs. While the statistics part deals with maintaining or keeping track of the number of types the PRMs with
elapsed time. Provision is made to reset and to start a fresh, to get print and to save the statistics.

- Transmit and Capture Digits:
The Capture Dialed Digits application provides the capability to capture and display DTMF and MF (along with MFR2-forward
and MFR2-backward) digits as they are received on one or several time slots. This application provides two basic modes of operation:
Manual and Scan for Offhook Modes.

- Dial Digits:
DTMF, MF, MFR2-F, and MFR2-B are the formats in which digits are transmitted using
transmitter. The digits can be dialed (1,2,3,4,5,6,7,8,9,*,0,#,A, B,C,D) and MF, MRF2-F, MFR3-B (1,2,3,4,5,6,7,8,9, ST,0,KP,STP,ST2P,ST3P),
which will be displayed in the Transmit Digit String. Digit ON / OFF time is set in msec for the transmission. The Digit Power is set in dB.
- Set Up / Processing Options:
With the help of this the digits can be transmitted continuously. Interval
between transmissions option is set as off time, and is displayed (in msec) at the end of every transmission. This should not exceed
1 Sec (1000msec). The commands failed and the failure counts are displayed in Command Failure Count.
- Transmit Setup:
The port # and the timeslots for digit transmission is set in this window.
Enabling the Start Monitoring button and Call button in Transmitter tab the Timeslot selected, Sync gain and loss, Correct Digits,
and InCorrect Digits are displayed.

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.
