Press Release: GL Releases Portable T3 E3 T1 E1 Analyzer Unit

Gaithersburg, Maryland, USA - October 7, 2008 - GL Communications Inc. announced today the release of a Portable All-in-One T3 E3 T1 E1 Ethernet Analyzer Unit. In a statement to the press, Mr. Jagdish Vadalia, Senior Manager of Product Development, said, "The size of a small paperback book and weighing only 1.75 lbs, GL's newest T3 E3 T1 E1 Ethernet Analyzer is one of the smallest and lightest analyzer units in the world. The pod when connected to a Notebook PC is capable of capturing two full T3 / E3 data streams, dropping and inserting T1 or E1, full Ethernet analysis, and HDLC, ATM, FR, and PPP Analysis."

Mr. Vadalia further added, "GL's T3 E3 T1 E1 Ethernet Analyzer can also be used in conjunction with GL's Laptop T1 / E1 analyzer for individual T1, E1, DS0, and Analog analysis. This analyzer is highly portable and flexible to operate - it can work with a desktop or a laptop PC". He added, "Many more such functions are being added to the analyzer that would enrich the capability and utility of the product".

Interfaces Supported

GL's T3 E3 T1 E1 Ethernet Analyzer comes with a variety of interfaces as shown below:

T3 or E3 - BNC interface (2 Transmit and 2 Receive ports)
T1 or E1 - RJ-45 interface (2 Transmit/Receive Ports)
External Clock: MBX (2 - one each per T3/E3 ports)
Ethernet Port - For wirespeed Ethernet analysis, remote monitoring, and management
USB - 2.0 - The USB interface is used to connect the analyzer unit to a Desktop or a Notebook PC for storage, display, and control

Receiver Capabilities:

Line testing and diagnostics: The T3/E3 Receiver can non-intrusively monitor a T3/E3 bit stream, and present a comprehensive diagnostics of PCM impairments and alarm messages in real-time.

Logical Diagram of Record (Capture) Application

De-multiplex T1 or E1 signals: User selected T1 (or E1) channels can be dropped using the T1/E1 input/output interface. Up to two T1 or E1 channels can be dropped from any one of the received T3 or E3 signals.

Capture Entire T3 or E3 Stream: The T3 E3 analyzer can capture (record) two complete T3/E3 streams to the hard drive as a binary file.

Transmitter Capabilities:

Line testing and diagnostics: T3/E3 transmitter can inject errors and alarms as well as do Bit Error Rate (BERT) testing.

Multiplex T1 or E1 signals: Up to two user selected T1 (or E1) channels can be externally inserted using the T1/E1 input/output interface into any one of the transmitted T3 or E3 signal. The inserted T1 or E1 signal can be selectively transmitted through one or more of the T1/E1 transmit channels, or broadcasted through all the T1/E1 channels. Additionally, the received T1/E1 signal can be looped back and transmitted or the transmitted T1/E1 signals can be set to carry AIS as shown in the picture below.

Playback (Transmit) entire T3 or E3 Stream from the PC hard drive: The T3 E3 Analyzer can also transmit (playback) an already captured binary file through the T3/E3 stream.
