GL Communications Inc. , announced today the availability of its ATM Protocol Analysis and Emulation software.

ATM Protocol Analyzer

The analyzer can decode ATM frames constituting Classical IP over ATM, or CIP based networks, and traditional SS7 Stack over ATM. ATM IMA Emulator performs IMA simulation on up to 16 T1 E1 ports.

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 ATM Protocol Analysis and Emulation software.

Speaking to media persons, Mr. Jagdish Vadalia Senior Manager for Product Development of the company said, ”GL's ATM Analyzer is used to analyze and decode different ATM protocols like ATM, AAL2 Protocols (CPS-SDU, SSSAR-SDU, and SSCS), AAL5 (CPCS), UNI etc across U plane and C plane of UNI and NNI interface. The analyzer can also decode ATM frames constituting Classical IP over ATM, or CIP based networks, and traditional SS7 Stack (ISUP, SCCP, MAP, CAMEL (CAP) etc) over ATM. The analyzer is also capable of capturing & reassembling frames that were transmitted with Inverse Multiplexing. IMA combines up to 8 T1 E1 links to form a single high-speed connection with flexible bandwidth options.”

He added, “The Inverse Multiplexing over ATM (IMA) Emulator application can simulate the inverse multiplexing of an ATM cell stream over multiple physical links and retrieve the original stream at the far-end from these physical links. The multiplexing of the ATM cell stream is performed on a cell by cell basis across the multiple physical links. Traffic source can be sequence number, HDL files (containing packets/frames), flat binary file, user-defined frames (ASCII HEX file), and Ethernet data.”

Some of the Important Features Of ATM Protocol Analyzer

·Displays Summary, Detail, Hex-dump, Statistics, and Call Detail Views
·Call trace capability based on UNI signaling parameters, VPI/VCI etc.
·CRC verification for AAL5 carrying packet data.
·Support of various UNI Signaling Protocols i.e. UNI 4.0, UNI 3.1 and UNI Q-2931
·Supports decoding of Classical IP over ATM
.Supports Multi-Protocol over ATM
.Supports SS7 signaling over ATM
·Supports search and filtering capabilities
·Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields
·Ability to configure .ini file to get the proper decoding (customize options such as VPI:VCI values, or detect presence of HEC in ATM header)

Some of the Important Features Of ATM IMA Emulator

·Performs IMA simulation on up to 16 T1 E1 ports
·ATM links can be created on full or fractional timeslots
·Supports hyper channels with discontinuous (sparse) timeslots
·IMA Frame Length can be set equal to 32, 64, 128, or 256
·Dynamically add/remove (Open/Close) of ATM links without loss in data
·Multiple IMA groups can be created with each group configured with multiple virtual channels for traffic tx/rx.
·Generate and verify end to end traffic on each Virtual Channel
·User configurable ATM (AAL 5, AAL 2) Packet size.

About GL Communications Inc.,

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.
