Press Release: GL Announces Protocol Identifier Software
Gaithersburg, Maryland, USA - May 5, 2010 - GL Communications Inc., announced today the release of its
newest product Protocol Identifier Software. Speaking to reporters,
Mr. Karthik Ramalingam, Project Manager at GL, said, ďThe Protocol Identifier
application can identify various protocols carried on T1 or E1 lines. It is capable of detecting protocols such as ISDN,
ATM, HDLC, MTP2, LAPD, SS7, PPP, GSM, GSM Abis, TRAU, and Frame Relay. The timeslots and or subchannels within
timeslots are also identifiedĒ.
He added, ďOnce identified, detailed analysis can be carried out by individual Protocol Analyzers. This application is
helpful in identifying traffic types at a concentration point, DSX patch panel, or multiplexed facilityĒ.
- Capable of identifying and classifying traffic over T1E1 based on HDLC, ATM, and TRAU protocols.
- Classification of HDLC based protocols such as ISDN, SS7, PPP, Frame Relay, and GSM.
- Graphical view displays the timeslots and subchannels of the identified protocols.
- Statistical view displays the different protocols with the details of port, timeslots and subchannel.
- Stream Statistics view shows the count of total number of timeslots, sub-channels, and hyper-channels used by
- Provides an option to log the protocol detected with device and channel information into a text file.
- Supports filtering to display the unique selected protocol.
- Supports custom configuration of the colors to easily distinguish protocols.
- Snapshot: Obtain a real-time snapshot of protocol traffic on T1E1 lines.
- Surveillance : Identify protocol traffic on all the timeslots/sub channels simultaneously on multiple T1E1 lines.
- Maintenance: Helps technicians to quickly identify the content of any T1 or E1.
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.
GLís 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.
GLís 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) are all available.
GLís 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
GLís Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic
echo. GLís compliance testing per G.168. G.167 and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted
in the industry.
GLís 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.
GLís 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.
GLís 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
