GL Enhances T1 E1 Emulation / Analyzer Products & Software

Gaithersburg, MD, October 29, 2014 --( GGL Communications Inc., announced today the release of its enhanced T1 E1 Analyzer Software and Hardware and now it is version 8.10.1.

Speaking to the media, Mr.Vijay Kulkarni, CEO of the company said, "Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting. Our T1 E1 line of products provides comprehensive analysis and emulation capability of any product on the market. Any traffic over T1 E1 lines including voice, fax, modem, signaling, mobile, IP, VoIP, ATM, and more is addressed.”

He explained, “Our newly introduced tScan16TM is a high-density T1 E1 board with 16 Rx 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.

“Our new Dual T1 E1 Express (PCIe) Boards are high-density Dual T1 or E1 boards with newer PCIe (x1) bus interface. These cards are identical to the portable tProbe™ units except for FXO FXS and Datacom functionality. In addition to basic T1 E1 applications and optional special applications, Dual T1 E1 Express (PCIe) Boards also support enhanced VF drop and insert with software selectable VF Tx and Rx impedances (135 Ω, 150 Ω, 600 Ω, 900 Ω, or High), Pulse Mask Compliance, Jitter Generation and Measurement testing applications.”

Mr. Kulkarni further explained, “Our software products: HDLC Tx Rx Server is WCS based server module that provides HDLC frame transmit/receive capabilities over HDLC streams on T1 E1 lines. It permits to create multiple HDLC streams of various bandwidths (time-slots, hyper channels, and sub channels) and provides UDP interface to the client applications for data Tx/Rx over these newly created HDLC streams. The application (client) and the HDLC Tx Rx server exchange the data over UDP transport.

“The WCS LAPD Server provides Layer 3 LAPD protocol services over GL's T1 E1 boards. It permits to create multiple LAPD links of various bandwidths (time-slots, sub-channels) and provides UDP interface to the client applications for generating & receiving LAPD payload over these created LAPD streams.

“MAPS™ ISDN Conformance Test Suite provides conformance for various ISDN and LAPD call states over T1 E1 as defined in the ITU-T Q.931 and Q.921 standards.

“MAPS™ IUP is an advanced protocol simulator used to simulate UK Specific SS7 IUP in British Telecom (BT) networks over TDM (T1 E1). It is designed to simulate Incoming and Outgoing Networks via Interconnect route as defined by the PNO-ISC/INFO/004(IUP) and TGS/SPEC/006 specifications. MAPS™ IUP functionality covers the UK variant of SS7 implementing MTP2, MTP3 protocol standards.”

He added, "There are also key enhancements introduced to some of the existing applications and to name a few: Basic T1 E1 Analyzer software, Datacom Analyzer, Multichannel Audio Bridge, Call Capture and Analysis (CCA), Protocol Analyzers and Packet Data Analysis applications."
