GL Communications Inc. announced today the availability of its Frame Relay Protocol Analysis and Emulation software.

Frame Relay Analyzer

Frame Relay Protocol Analyzer can be used to analyze and decode frames conforming to Q.921, Q.922, LAPF, FR Forum standard -FRF.9 and FRF.12 and more. FR and MFR can be emulated and analyzed using GL’s client-server based MFR Emulation & Analysis.

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, announced today the availability of its Frame Relay Protocol Analysis and Emulation software.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, ” GL's Frame Relay Protocol Analyzer can be used to analyze and decode frames conforming to Q.921, Q.922, LAPF, Frame Relay Forum standard -FRF.9 and FRF.12, Multiple Protocol Encapsulation, LCP RFC1661, Q.933 SVC and LMI SNAP, PPP, IP, SMTP, POP3 and so on.”

He added, “Multilink Frame Relay (MFR) is used to derive a larger frame relay pipe by aggregating smaller frame relay pipes. For example, 5 T1 frame relay pipes could be bundled to appear as a single 7.5 Mbps frame relay pipe. Some of the advantages of using MFR are: better bandwidth sizing according to customer traffic requirements and potentially better QOS by minimizing delay.”

Mr.Vadalia further added, “Frame Rleay (FR) and Multilink Frame Relay (MFR) can be emulated and analyzed using GL’s client-server based MFR Emulation and FR Analysis software modules. MFR is an optional application for GL’s Card and USB based T1 E1 platforms.”

Some of the Important Features Of Frame Relay Protocol Analyzer

·Supports decoding of encapsulated protocols, and long frames up to 16 Kbytes
·Analyze Permanent Virtual Connection (PVC) and Switched Virtual Connection (SVC) frames
·Supports filtering and search based on LAPF parameters and Q.933 layer parameters such as DLCIs, Message Type, FECN, BECN, DE, NLPID's TCP, IP, SMTP, POP3, and so on
·Displays Summary, Detail, Hex-dump, Statistics, and Call Trace Views, the contents of this view can also be copied to clipboard
·Call Detail View displays called/ calling number, released calls, call status, & more
·Call Detail Recording feature includes data link groups that help in defining the direction of the calls in a given network and form logical groups comprised of unidirectional (either 'Forward' or 'Backward') data links.
·Capability to export Summary View details to a comma separated values (CSV) format for subsequent import into a database or spreadsheet
·Capability to export detail decodes information to an ASCII file
·Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields
·Remote monitoring capability using GL's Network Surveillance System

Some of the Important Features Of Frame Relay Emulator

·Performs MFR as well as FR simulation on up to 16 T1 E1 lines
·Adheres to FRF.12 standards
·Support two simulation modes - FR and MFR
·FR links can be created on Full or Fractional Timeslots
·Group FR links to create a MFR bundle
·Dynamically add/remove (open/close) of Frame Relay links without loss in data
·Multiple MFR Bundles/FR links can be created with each bundle/link configured with multiple virtual channels for traffic tx/rx
·Generate and verify end to end traffic on each Virtual Channel
·User configurable FR/MFR packet and fragment size, bandwidth using flags, and maximum link differential delay
·Supports both Interface (UNI and NNI) and End-to-End fragmentation
·Supports various traffic source/sink types namely, Sequence Number, Binary File, Hex String, and pre-captured HDL files

About GL Communications Inc.,

Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax. Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC, and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) is available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
