Press Release: GL Communications Inc. Enhances T1 E1 Applications with Automated Continuous Capture (ACC)

Gaithersburg, Maryland, USA - March 1, 2007 - GL Communications Inc., announced today the release of their enhanced T1 E1 Applications with Automated Continuous Capture (ACC) capability. Addressing the press conference, Mr. Jagdish Vadalia, Product Manager, said, "The Automated Continuous Capture application (ACC) can non-intrusively record T1 E1 traffic continuously for an indefinite period of time, but is flexible enough to access the captured data at near real-time or regular intervals". He added, "It is an optional application for GL's USB based or PCI Card based T1 E1 Analyzers, and permits capturing of T1 E1 data on (any one or all) T1 E1 channels to user-defined files. The data captured is saved as seamless chunks of data in "contiguous" files. "Chunks" can be defined as fixed sizes or fixed time periods".

Important Features:

  • Captured data can be from contiguous and / or non-contiguous timeslots
  • Bytes may be captured in reverse order or normal order
  • Fixed capture size (specific number of bytes or time periods) to files from all or selected timeslots
  • Capturing from multiple dual cards in single PC system - depending on PC horsepower, up to 8 full duplex T1/E1s can be captured in their entirety

Various options in ACC to continuously capture data are:

  • Captures based on size - possible to capture data for the mentioned file size in bytes
  • Captures based on time - files can range from as low as 1 minute to possibly 24 hours
