Overview

GL's Dual T1 E1 Express (PCIe) Boards are high-density dual T1 or E1 boards with newer PCIe (x1) bus interface.  These cards are identical to the portable tProbe™ units, except for FXO FXS and Datacom functionality.

In addition to the other basic T1/E1 line signals monitoring applications, the Dual T1 E1 Express (PCIe) Boards also support enhanced VF drop and insert capabilities  with software selectable VF Tx and Rx impedances (135Ω, 150 Ω, 600 Ω, 900 Ω, or High), Pulse Mask Compliance Testing, Jitter Generation and Measurement applications.

Accompanying Basic Software / Features

Dual T1 E1 Express (PCIe) Card comes with "basic applications" for basic testing needs and optional "special 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 tProbe™ T1 E1 analyzers are also supported by Dual T1 E1 Express (PCIe) Card. 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 -http://www.gl.com/t1e1applications.html.

Additional applications supported by Dual T1 E1 Express (PCIe) Card 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 Dual T1 E1 Express (PCIe) Card 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 Generation and 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. 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.

Jitter Generation allows the user to generate a jittered output T1 E1 signal with user-selected jitter frequency and amplitude.  It is suitable for testing jitter tolerance and compliance with standards such as G.823.  Jitter Generation application in conjunction with Jitter Measurement application may also be used to test jitter transfer.

Loopbacks

Cross-port Through Loopback

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

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.
