Accompanying Basic Software / Features
tProbe™ 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 USB T1 E1 analyzers
are also supported by tProbe™. 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 tProbe™ 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 tProbe™ 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
tProbe™ 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.
