Press Release: GL Announces Protocol Analysis / Emulation for T3 E3 Transmission Systems

Gaithersburg, Maryland, USA - February 2, 2009 - GL Communications Inc., announced today the availability of a set of Protocol Analyzers/ Emulators for T3 E3 Transmission systems. In a statement released to the press, Mr. Jagdish Vadalia, Senior Manager of Product Development for GL said, "GLís T3 (DS3) / E3 analyzer supports protocol decoding and analysis of ATM, Frame Relay, MLPPP, and HDLC". He added, "All the protocol analyzers are based on similar architecture and support sophisticated filtering, statistics and real-time capture options".

Mr. Vadalia further added, "The newly added portfolio of select Protocol Analyzers would address the need of the telecom community who are on the lookout of cost effective Protocol Analyzers for T3 E3 Transmission Systems".

A brief description of T3 E3 Protocol Analyzer and Emulator is given below:

PPP Protocol Analyzer for T3/E3

The PPP Analyzer captures a host of PPP protocols exchanged between the two nodes over T3 E3 links and provides useful analysis, which includes distribution of protocols, protocol fields, frame lengths and frame status. User can obtain detailed analysis of the protocol and can gather various statistics and measurements.

Some of the important features:

  • Supports a host of protocols including PPP, IPCP, BCP, BPDU, PAP, CHAP, HTTP, SNMP, STUN, FTP, DNS, and DHCP
  • Ability to test and perform numerous measurements across WAN- LAN or LAN-LAN connection
  • Ability to test and analyze HDLC based PPP protocol in synchronous environment
  • Search and filtering capabilities for both real-time as well as offline analysis.

For comprehensive information on the product, please refer to T3 E3 PPP Protocol Analyzer web page.

ATM Protocol Analyzer for T3

GL's T3 ATM Analyzer is used to analyze and decode different ATM protocols like ATM, AAL2 Protocols (CPS-SDU, SSSAR-SDU, and SSCS), AAL5 (CPCS), UNI and others across U plane and C plane of UNI and NNI interface.

Some of the important features:

  • Displays Summary, detail, hex-dump, statistics, and call trace views
  • Summary View displays Dev #, Frame #, VPI/VCI, PT (Payload Type), HEC, OSF, AAL Type, Frame Type, CID, LI, CPI, UUI, SSSAR CID and SSCS message type etc
  • Detailed view displays decodes of user-selected frames
  • Hex dump view displays raw frame data as hexadecimal and ASCII octet dump

For comprehensive information on the product, please refer to T3 ATM Protocol Analyzer web page.

Frame Relay Protocol Analyzer for T3 E3

Frame Relay is another commonly used data link protocol based on packet switching technology. It is mainly incorporated into corporate data networks due to its cost-effective data transmission, and flexible bandwidth.

Some of the important features:

  • 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 features 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.
  • Provides Summary View, Detail View, Hex dump, statistics, and call trace views.

For comprehensive information on the product, please refer to T3 E3 Frame Relay Protocol Analyzer web page.

HDLC Protocol Analyzer / Emulator for T3 E3

GL's T3/E3 HDLC protocol analyzer provides the capability to capture, and analyze HDLC data on a T3/E3 lines. There may be a single data channel per T3/E3 line. After setting the T3/E3 ports and FCS type and starting the decoding process, the main screen displays the captured HDLC frames. Flags are stripped, and all other data is presented, including FCS bytes.

Some of the important features:

  • Displays Summary, detail, hex-dump, statistics, and call trace views
  • Summary view displays device#, frame#, LAPD, LAPF specific information and IP information like source/destination IP address, TCP source port, TCP destination port etc
  • Detailed view displays decodes of user-selected frames
  • Statistics view displays statistics based on frame count, byte count, frames/sec, bytes/sec etc for the entire captured data
