Gaithersburg, MD, USA (Vocus) 15 September 2010

GL Communications Inc. announced today the release of its improved ISDN, GSM, and SS1 MLPPP protocol analyzers. Talking to news persons, Mr. Vijay Kulkarni, CEO of the company, â? GL with the widest range of protocol analyzers for TDM, cell and packet switched networks. Based on a unified architecture with similar characteristics and functions, they can be used flexibly for a variety of tasks, including

? ¢ as independent autonomous units for the analysis of simple interface

â? ¢ analyzers, remote control or offline

â? ¢ as “probes” integrated network monitoring systems

â? ¢ as network elements for the collection and processing of advanced transport

Typical examples are

, continuous recording of the exchange protocol over an ISDN interface, which limited only by the hard disk or network storage or release, collecting and filtering information and subscriber data only relay the information back to a processor or collection of information for CDR> Billing ????.

He added: â? GL ISDN Analyzer can capture and analyze all frames of an ISDN PRI. It decoded as Q.921 LAPD, while the analysis information on Layer 3 ISDN user selection ISDN-based variants. The analyzer now supports the new protocol standard ECMA QSIG (ECMA-143 standard 4th Edition – December 2001).

GSM Analyzer is used for display and analysis of GSM protocols on the GL-proven Ultra E1 or T1 internal cards or Laptop E1 or T1 Ultra portable external products. The improved parser to support: Call Control Group (CCG) protocol (specification – 3GPP TS 44 068 v9.0.0) implemented to support is VGCS (Voice Group Call Service) function for the GSM-R (Global System for Mobile Communications – train). And Broadcast Call Control (BCC) protocol (specification – 3GPP TS 44 069 v9.0.0) is formed, VBS (Voice Broadcast Service) according to the GSM-R – support (Global System for Mobile Communications track).

ML PPP Analyzer can be used to capture and decode a large number of PPP protocols between pairs of nodes on T1 E1 connections are replaced. It provides a useful analysis of the PPP, PPP, ML, ML / MC-PPP, the distribution of protocols, protocol fields, frame lengths and frame status reports. The analyzer is now analyzing the analysis of VoIP data packet to VoIP calls by the TDM lines performed. It has been also renewed support for decoding multiplexed compressed RTP and PPP improved.


Our

SS1 Analyzer detects and analyzed sequences from which your SS1 numbers. The pulse sequences of notes and care are identified, decoded, and assembled in their> dial digitsâ p corresponding ????. Mr.Kulkarni added: â? Improvements to our protocol analyzers to better meet the needs of the user community about the growing complexity of telecommunications and transmission advancementsâ p> ????. other important characteristics of analyzers

ISDN Protocol Analyzer

? ¢ summary shows, detail, hex-dump, statistics and call detail views

â? ¢ Call Trace isolates specific call to find out the status information known about each call (ie active / completed), duration of the call, the second device, time interval, CRV, and the number of the complainant

â? ¢ Call Detail Recording feature includes data link groups define the orientation of the calls in a given network and help create logical groups of unidirectional (either ‘Forward’ or ‘down’) data links

â? ¢ Supports filtering and search functions to SAPI, TEI, C / R, N (S), N (R), P / F message, the monitoring functions and ISDN types

Base

GSM Protocol Analyzer

? ¢ summary shows, detail, hex dump, statistics and call detail views

â? Summary View displays MTP2 MTP3 ¢ Information, GSM message types, information on various channels are used during the call, the frequency-hopping and so forth in tabular form

â? ¢ Call Detail view displays statistics such as number of active / calls, duration of calls, call-type call (eg SMS / Place Update / authentication / Speech call), IMSI / TMSI associated with each call

â? ¢ Call Detail Recording feature includes data link groups define the orientation of the calls in a given network and form logical groups of unidirectional (either ‘Forward’ or ‘down’) data links
PPP and ML

analyzer PPP

? ¢ supports multiple protocols, including PPP, ML PPP, Multi-Class ML PPP, IPCP, BCP, PPP MUX PC, PTRC, BPDU, PAP, CHAP, HTTP, SNMP, STUN, FTP, DNS and DHCP

â? ¢ Ability to test and many actions in the WAN-LAN or LAN-LAN

â? ¢ Ability to test and analyze HDLC based PPP protocol in a synchronous environment

â? ¢ Provides summary, details, statistics and views Hex-Dump

â? ¢ offers See the summary information on some important areas (Dev # Time Slot, Layer 3 protocol, message type LCP and more accurate information such as source and destination protocol IP address, TCP source and destination as well as details of the UDP, HTTP / FTP message type, and so on)

SS1

dialers and Analyzer


Real-time analysis of file-based
â? ¢ Generates introduce and SS1 speed dial numbers on the transmission channels with SS1 Dialer

â? ¢ Controls mark and space frequencies and the duration and power during the transmission of sound SS1

â? ¢ surveillance capabilities that tap multiple instances of double SS1 analyzer, both the circulation and EW

â? ¢ the option of either audio or CT scans

â? ¢ simple configuration screens, the criteria used to evaluate the sequence of sounds SS1, including references to the use of speed dial numbers to 2 digits or 3 digits

â? ¢ given indicated primaries, including the properties of the underlying tones. Dial Codes highlighted underlying tone sequences that are not the criteria are clearly identified with the wrong tone characteristics
