Newsletter: GL Announces High-Density 
16 ports T1 E1 Analysis Hardware

Welcome to another August 2014 issue of GL's Newsletter providing information and insight into our latest T1 E1 Analysis Hardware tScan16™ (16 T1 E1 Rx only ports) boards.


GL's tScan16™ is a high-density T1 E1 board with 16 ports and the newer PCIe (x1) bus interface. The sixteen T1 E1 ports are Receive-only ports optimized for high performance voice and data capture, monitoring, and analysis requirements. 

tScan16™ extends the family of GL's T1 E1 platforms with greater density, increased ports, and reduced power. 

Main Features

  • Software selectable 16-Rx Only T1 or E1 interfaces
  • PCI Express x1 Lane/Board
  • Convenient High Density Cabling
  • Monitor T1 E1 line conditions such as frame errors, bipolar violations, alarms, frequency, and power level.
  • Most all "Rx Applications" are available with tScan16™
  • Analysis of ISDN, SS7, Frame Relay and Multilink Frame Relay, PPP and Multilink PPP, HDLC, and many more protocols
  • Comprehensive analysis of Voice, Data, Fax, Protocols, and Digital signals, including Echo and Voice Quality testing
  • Call Recording, Analysis, and Monitoring for hundreds to thousands of calls in one platform
  • Compatible with Windows® 7 and 8 Operating System and GL's user friendly real-time software

Comparison and advantages of the new tScan16™ over Quad/Octal T1 E1 Boards is given in the following table.
