GR-303 Protocol Analyzer

The GR-303 option troubleshoots signaling problems between the switch and remote terminal: to determine call status, monitor for any dropped calls, detect any abnormal conditions, and identify when service was unavailable

GL Communications Inc. a leader in providing PC-based test, analysis and simulation products and consulting services to the worldwide telecommunications industry, conveyed today the availability of its GR-303 Protocol Analyzer software.

Speaking to media persons, Mr. Vijay Kulkarni CEO of the company said, ”GL's GR303 Analyzer offers testing for all aspects of GR-303 systems: monitoring T1 Line, monitoring the TMC/CSC control channel, monitoring EOC channel, viewing robbed ABCD signaling and dialed digits, listening to voice channels, and thorough tests for the physical layer.”

He added, ”The GR-303 option troubleshoots signaling problems between the switch and remote terminal: to determine call status, monitor for any dropped calls, detect any abnormal conditions, and identify when service was unavailable. With these extensive GR-303 protocol analysis tools, you can analyze call setup and monitor communications between network elements and resolve problems as new network challenges emerge.”

Some of the important features:

·Decode Embedded Operational Channel (EOC) messages for diagnosing operations, administration, maintenance and provisioning (OAM & P).
·Provide real-time call-setup analysis of the Timeslot Management Channel (TMC) and Common Signaling Channel (CSC).
·Monitor both TMC/CSC and EOC simultaneously to correlate call-setup and OAM&P.
·Provides Summary, Detail, Hex dump, Statistics, and Call Detail Views.
·Summary View displays the SAPI, TEI, C/R, Message type (for TMC/CSC) and ROSE APDU (for EOC).
·Detail View displays decodes of user-selected frames from the Summary View.
·Hex dump View displays raw frame data as hexadecimal and ASCII octet dump.
·Statistics View displays statistics based on frame count, byte count, frames/sec, bytes/sec etc for the entire captured data.
·Call Detail View displays call statistics such as number of active/completed calls, durations of the completed calls, Device No, CRV and Timeslot.
·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 decode information to an ASCII file
·Supports filtering and search based on Call Reference Value (CRV) and many other message types
·Remote monitoring capability using GL's Network Surveillance System

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.
