Newsletter: GL Enhances T1 E1 Analyzer Products and Software Ver 5.13
Welcome to GL's Newsletter covering the latest products, features, and enhancements to our versatile
T1 E1 Analyzer product line (Ver 5.13).
Universal T1 E1 Boards vs. Older HD T1 E1 Boards:
- Universal T1 E1 PCI Cards:
GL has added to its T1 E1 Analyzer hardware test suite new hardware called "Universal T1 E1 Analyzer". These cards
easily plug into PCI 2.1 Compliant slots of any Pentium PC. The advantage it offers over the prior version of HD PCI T1 E1
cards is that it includes integrated hardware support for both T1 as well as E1 lines, thus allowing easy switching between
T1 and E1 interface testing.
- Universal Boards are capable of T1 and E1 interfacing. Only software and drivers differentiate whether
T1 or E1 signals are being processed. In the earlier versions, T1 was a different board than the E1
- Universal boards can be plugged into either a 5 V or 3.3 V PCI bus, i.e. (PCI 2.1 Compliant). Earlier T1 boards and E1
boards could only be plugged into a 5 V bus
- Universal boards have adjustable transmit clock frequency for testing frequency lock sensitivity of T1 or E1 equipment.
The transmit clock can be adjusted + / - 300 PPM
- Two new port modes have been added: cross-port loopback and thru mode
- Cross-Port Loopback
This mode is similar to the standard "Outward Loopback" except that the signal received on Card 1 (Port 1) can be
transmitted out onto Card 2 (Port 2). Likewise the signal received on Card 2 (Port 2) can be transmitted out onto
Card 1 (Port 1). The hardware defaults to this mode (cross-port loopback) whenever the board is powered up or down.
This feature allows you to monitor T1 / E1 lines "in-line" while still being protected from loss of power to the board.
- Thru Mode
When Thru Mode is selected, the data that would normally be transmitted on Card 1 (Port 1) is diverted to transmit
on Card 2 (Port 2) and the data that would normally be transmitted on Card 2 (Port 2) is diverted to transmit on
Card 1 (Port 1). The receive paths are completely unaffected. This mode is particularly useful for Drop and Insert
applications in which the board analyzes and may insert traffic running between two pieces of T1/E1 equipment.
This feature eliminates complex cabling.
- Pulse Mask Display:
Incoming pulses are tested for compliance against T1 or E1 standard pulse mask specified by the ITU G.703 standard
and ANSI T1.102-1993. This feature is also available with the Client Server software for automation and remoting
- Jitter Measurement and Generation (coming soon):
Jitter can be measured in the incoming T1 E1 signal. Jitter can also be introduced onto the outgoing T1 E1 signal.
Software for this application will be available soon.

This Client-Server application is used for performing complete ISDN switch and subscriber emulation. The functions that can
be performed using client-server are:
- Configuring the ISDN layer parameters, called/calling numbering plan/type, type of ISDN service
- Placing and accepting calls for each timeslot or for the whole trunk
- Loging call records for complete or incomplete calls
- Simple NFAS setup for T1
For comprehensive understanding of the enhancements introduced to the product, please visit the
ISDN Emulator webpage.
WCS Pulse Mask:
This Client-Server application in Universal boards is used for detection, monitoring, and plotting of transmitted pulses.
It includes Monitor Pulse Mask and Pulse Mask Display modules that can be remotely controlled using simple commands by
client applications. Some of the commands supported are CheckPulseMask, validate pulse, stop pulse mask validation, and

TRAU ToolBox™ and Analysis
Multi-Class ML-PPP Emulator
- The "tx server file" command in Error Insertion module of WCS has been modified to transmit data on multiple cards
which has improved the performance of the tester
