GL Enhances T1 E1 Emulation / Analyzer Products and Software

Welcome to another issue of GL's Newsletter covering new applications and enhancements for our versatile T1 E1 analyzer product line.

T1E1 Hardware Platform Cards


GL’s T1 E1 analyzer is a powerful, fully-featured BERT, voiceband, data, signaling, and protocol analysis tool. The analyzer can perform analysis and emulation of various signal types including voice, digits, and tones; and various protocols including HDLC, ISDN, SS7, CAS, Frame Relay, GSM, GPRS, CDMA, and UMTS. It is capable of T1 or E1 PCM signal visualization, capture, storage, analysis, and emulation.

In addition, convenient features are available like portable, USB-friendly interface to a PC, single or dual multiport repeaters, and scripting. T1 E1 analyzer is also available in mTOP™ rack enclosures with USB-based units which can be stacked to provide a high-density form factor solution.

Recent Enhancements

  • Support for Unframed mode in "Frame Relay Emulator" has been added where user can include Timeslot 0 for transmission/reception
