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.
It is introduced with the following enhancements:
|
|
|
- Capable of both T1 and E1 interfacing.
- T1 or E1 interfacing – Software Selectable
- Universal boards can be plugged into either a 5 V or 3.3 V PCI 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.
- Supports two new port modes: Cross-port through mode and Cross-port transmit mode
- Features in-service monitoring and emulation of T1 and E1 circuit connections.
- 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
- T1 E1 Pulse Shape and Jitter Measurement Analysis
- 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.
- 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.
GL's offers other popular forms of T1 E1 analysis hardware such as Octal/Quad T1 E1 Analyzer Boards - 8/4
port PCIe based cards for higher scalability and performance, Portable USB T1 E1 Analyzer with Dual T1 E1 ports & smallest form
factor, Universal T1 E1 Analyzer Boards - a dual port PCI based T1 E1 analyzer offering higher speed and smaller dimensions.

Accompanying Basic & Optional Software
GL’s Universal T1E1 Analyzer software comes with “basic software applications” for basic testing needs and “optional software applications” that extend the
capability far beyond the most expensive T1 E1 VF and Serial Data testers. All the basic applications and optional applications supported by legacy HD T1 E1 boards
are also supported by Universal HD T1/E1 Boards. For example, capturing and transmitting an entire raw T1 E1 VF or Serial Data signal simultaneously on two full
duplex ports, or performing ISDN emulation, or SS7 analysis, or analyzing echo and voice quality on voiceband channels, to name a few.
A list of all the basic applications and other optional applications (requiring additional licenses) are
listed here.
Additional applications supported by Universal HD T1/E1 boards are as follows -
Pulse Mask Compliance Testing (Available only with tProbe™ and Universal HD T1 E1 cards)
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 (Available only with tProbe™ and Universal HD T1 E1 cards)
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. Cumulative jitter is of primary importance
as network equipment must cope with the cumulative jitter by the use of appropriately sized “jitter buffers”. Tick-by-tick
measurements provide instantaneous jitter.

Loopbacks
Universal T1 E1 Cards supports Normal (no cross-port), Cross-port Through, and Cross-port Transmit loopbacks.
Cross-port Through Loopback
This mode is similar to the standard Outward Loopback except that the signal received on Card 1 (Port 1) is
transmitted out onto Card 2 (Port 2). Likewise the signal received on Card 2 (Port 2) is transmitted out onto Card 1
(Port 1). This feature allows monitoring T1/E1 lines in-line while still being protected from loss of power to the board.
This mode is effected entirely thru relays and eliminates complex cabling.
Cross-port Transmit Mode Loopback
In this Mode, the data that would normally be transmitted on Card 1 (Port 1) is diverted and transmitted on Card 2
(Port 2) and the data that would normally be transmitted on Card 2 (Port 2) is diverted and transmitted on Card 1
(Port 1). The receive paths are completely unaffected. This mode is particularly useful for Drop and Insert and Error
Injection applications in which the board analyzes and may insert traffic running between two pieces of T1/E1
equipment. This feature also eliminates complex cabling.
