Windows Client/Server for Datacom Analysis
tProbe™ Datacom Analyzer/Emulator is enhanced to support the Windows Client/ Server (WCS) scripted test software, providing the capability of remote operation, automation, and multi-site connectivity.Brochure
Data Communications generally refers to legacy interfaces of the recent past before packet technology became popular. These interfaces and methods of communications are still out there.
GL's Datacom Analyzer/Emulator is an optional board available with GL's tProbe™ T1 E1 Analyzer or is also available as a standalone unit. It is designed for test and verification of data communications equipment and circuits - specifically serial interfaces that provide clock, data, and control signals. It provides software selectable modes to analyze and emulate DTE and DCE interfaces, non-intrusive monitoring for both synchronous (sync), and asynchronous (async) modes.
tProbe™ Datacom Analyzer/Emulator is now enhanced to support the Windows Client/ Server (WCS) scripted test software, providing the capability of remote operation, automation, and multi-site connectivity.
Windows Client / Server provides the capability of remote operation, automation, and multi-site connectivity to the Datacom Analyzer. Datacom in a server mode can be easily controlled through software clients at remote or local sites via TCP/IP sockets. Connectivity can be via Dial-Up, LAN, WAN, or more typically the Internet. Server software runs multiple tasks simultaneously at the request of the client software.
With additional licensing, WCS supports Enhanced BERT module. Enhanced BERT is a Server function used to measure the correctness of data received on Datacom against a repetitive fixed or pseudorandom pattern for the given transmission. The application generates/detects unframed BER patterns such as - QRSS, 2^5-1, 2^9-1, 2^11-1, 2^15-1, 2^20-1, 2^23-1, All ones, All zeros, 1:1, 1:7, 3 in 24, CSU Loop-Up (0001), CSU Loop-down (001), NIU Loop-UP (11000), and NIU Loop-Down (11100), and user-defined patterns in real-time. Supports predefined error insertion rate and user defined error rates ranging from 0.01 to 1e-009.
GL provides sample-working clients in C++, VB, and TCL along with the server. Clients are compatible with any OS, including UNIX, Linux and Windows. Other environments commonly used for client development include Perl, MatLab, Visual Basic, and LabView.

WCS Enhanced BERT Commands:
bert pattern "qrss" dte1 invert continuous report 10 sec; // Pseudo-random pattern inverted
bert pattern 0xd5 dte continuous report events; // User-defined hex pattern
bert pattern "qrss" dte er 5e-7 continuous report 10 sec; // Pseudo-random pattern with error rate
Configuring DTE and DCE Simulation
WCS commands are used to configure DTE and/or DCE Interfaces for Loopback, CTS, RTS, DSR, DTR, DCD, RI, RL, TM, LL, Clock settings, Data Rates, Sync and Async mode, Async communications parameters such as Data Bits, Parity Bits, Stop Bits and to get the Signal Line Status as well.
WCS Datacom Commands:
set dc interface rs232 #*;
set data rate 115.2 kbps #*;
set data bits 7 #*;
set parity bits even #*;
set async comm parms 8,none,1 #*; // Restore sensible setting
get txd, rxd, txc, rxc status #*; // txd fails for dce, rxd fails for dce

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.
