Basic application are included with T1 E1 Basic Software
T1 E1 carriers are still used extensively throughout the world for carrying large volumes of call containing both voice and data. Their popularity can be attributed to their high reliability, manageability and flexibility. The available digitized channels, 24 for T1 and 32 for E1 carry voice and/or data. Further, the channels can be used separately or they can be combined to provide higher transmission bandwidth.
T1 E1 testers are available in various form factors from portable, handheld, and rack-based platforms. Regardless of the form-factor you choose, GL’s T1 E1 Test solutions provide a wide range of functionalities and testing capabilities. GL’s versatile T1 E1 Analyzer Hardware portfolio is briefly discussed in this webpage - http://www.gl.com/t1e1testing.html. Here we discuss a wide range software supported in GL’s T1 E1 test tools required for installing, commissioning and troubleshooting T1, E1, FXO, FXS, and Datacom lines.

- 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 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.
