Overview
The Universal HD T1/E1 is an enhanced PC-Based T1 and E1 solution that utilizes familiar computer user interfaces, to
provide comprehensive and versatile T1 or E1 testing capability at a competitive price.
The Universal HD T1/E1 card is capable of both T1 and E1 interfacing. This features in-service monitoring and emulation
of T1 and E1 circuit connections. It provides out-of-service troubleshooting such as bit-error-rate testing, alarm monitoring,
signaling bit manipulation and recording, DTMF/MF generation and detection, and Drop and Insert capabilities
The T1 (E1) Pulse Mask Application compares incoming T1 (E1) pulses against the pulse shape mask specified by the
ITU G.703 standard. Jitter measurement application can measured in the incoming T1/E1 signal for any unwanted
variations. Graphical views simplify the understanding of PCM data. Time-domain is presented using an oscilloscope
display, and frequency domain using spectral displays.
Voice Frequency Access: Besides providing access to in-band PCM data, the T1 (E1) provides VF interface for monitoring
and inserting audio with Drop and Insert. The unit also provides convenient handset interface for voice over the T1 or E1
line.
Remote testing and monitoring can be done using simple script based or GUI based client software.
Precision Delay Measurement under basic software measures the Round trip Delay of a system. Round trip delay
measurement is done by sending a BER pattern with the insertion of an erred bit and timing the reception of the erred
bit. Measurement is precise and accurate to the microsecond level. A delay up to 8 seconds can be measured. The internal
delay of the card is subtracted from the round trip delay.
Universal HD T1/E1 Boards
The Universal HD T1/E1 board can process hundreds of channels or timeslots simultaneously on T1 and E1 lines
Detail Description of Features in Universal cards
- Universal Boards are capable of T1 and E1 interfacing. Only software drivers differentiate whether T1 or E1 signals
are being processed. In earlier version, T1 & E1 boards were different
- Universal boards can be plugged into either a 5 V or 3.3 V PCI bus., i.e. (PCI 2.1 Complaint) Earlier T1 and E1 could
only be plugged into a 5 V bus
- Smaller Size – The boards are smaller, with dimensions are 4.2" x 7.1" vs. the older boards 4.2" x 9.2".
- High Density and High Speed - The boards are significantly faster, and significantly more efficient than the
older boards. The new boards use DMA and a 32-bit wide bus.
- CPU Utilization - CPU utilization with the newer boards is negligible. For example, one can simulate echo on
hundreds of timeslots by running simultaneously "delay/attenuate" on all 24 T1 ports on all timeslots. The new boards
are compatible with dual processor motherboards and software that simulates dual processors (i.e. hyperthreading).
- Universal boards have adjustable transmit clock frequency (+ / - 300ppm) for testing frequency lock sensitivity of T1 or E1
equipment. The transmit clock can be adjusted + / - 300 PPM
- Supports two new port modes: cross-port loopback mode and thru mode
- Additional applications available in the hardware (software coming soon) are:
- Pulse Mask: Incoming pulses are tested for compliance against the T1/E1 standard pulse mask.
- Jitter Measurement and Generation: Jitter can be measured in the incoming T1/E1 signal. Jitter can also
be introduced onto the outgoing T1/E1 signal
Accompanying Basic Software / Features
All the basic applications and optional applications supported by legacy HD T1 (E1) boards and USB based T1(E1) analyzers
are also supported by Universal HD T1/E1 boards. A list of all the basic applications and other optional applications (requiring
additional license) are listed here - http://www.gl.com/laptopt1.html#applications.
Additional applications supported by Universal HD T1/E1 boards are as follows -
Pulse Mask Compliance Testing
In T1 E1 transmission systems, signals are dropped, inserted, and accessed at the electrical level at a point called DSX patch panel or at some similar
point. To reliably receive, monitor, or access these signals, they must first conform to a standard that establishes parameters such as pulse width, rise time,
amplitude, allowable undershoot and overshoot. If the pulse meets the pulse mask, then a properly designed receiver should be able to decode the bits
transmitted.
GL's Universal T1 E1 Cards provides pulse mask compliance testing using Pulse Mask Display for both T1 and E1 applications. Software has been
developed to determine if the pulse shape fits within a "pulse mask" as specified by standards ITU G.703 and ANSI T1.102-1993. The software is available
in both visual and tabular formats. Tabular formats are convenient for automation and scripted test environments.

Jitter Measurement
Jitter along with wander and frequency drift are major impairments of clocks in synchronous systems. Jitter is the time discrepancy between the time of
arrival of a clock pulse and its theoretical arrival time. GL's Jitter Measurement module allows evaluation of jitter on either a tick-by-tick or a cumulative basis.
Technically, cumulative jitter is of primary importance as network equipment must cope with the cumulative jitter. However, tick-by-tick measurements are
also presented in this module.
GL Communications Inc. recognizes the following groupings of clock deviations – Drift (Very slow variations in a clock signal (below 1 Hz), and Frequency
Deviation (A permanent or steady-state difference in clock rates.

WCS Pulse Mask Compliance Testing
The Universal boards support client-server pulse mask application for detection, monitoring, and validation of transmitted pulses.
The client-server modules can be remotely controlled using simple commands by client applications. Some of the commands supported
are checkpulsemask, validate pulse, stop pulse mask validation, and others.
