GL Communications Releases Optical Channelized Emulation and Analysis

GL Communications Inc., announced today the release of its latest product LightSpeed1000™ with Channelized Emulation and Analysis of T1s and E1s - With its unique architecture, literally thousands of DS0s within T1s and E1s can be accessed directly within an optical SONET or SDH structure - with ease for emulation and analysis.

Speaking to the press, Mr. Jagdish Vadalia, a senior manager for product development of the company said, "SONET SDH technology forms the transmission backbone for TDM, IP, and Wireless networks. STM-1 and OC-3 optical transmission rates (155.52 Mbps) are the most common of the various dense pipes (in SDH SONET) carrying E1, T1, E3, T3, and Ethernet multiplexed signals.

To access and analyze channelized lines within OC-3 STM-1 can require specific and costly mux/demux hardware (perhaps at several layers) and unique test equipment. Direct access to any channel and traffic type within OC-3 STM-1 would negate the need for such additional bulky hardware and greatly simplifies testing, monitoring, and analysis cost effectively."

He added, "GL's LightSpeed1000™ in Channelized Mode provides such simplicity, permitting direct DS0 level access to hundreds of T1s and E1s, and in the near future all the E3s and T3s constituting the OC-3 and STM-1. This platform with its unique architecture eliminates the requirement for external multiplexing hardware and hundreds of cables and connectors. Multiple, independent streams of any user-defined capacity can be generated internally, analyzed, and monitored in real-time.

GL's LightSpeed1000™ supports Channelized SONET and SDH mapping to T1 E1 framing modes. When the LightSpeed 1000™ is configured in SDH framing mode, it is capable of supporting bidirectional channelization into 63 independent E1 channels. When configured for SONET framing mode, the LightSpeed 1000™ is capable of supporting bidirectional channelization into 84 independent T1 channels."

Mr. Vadalia further added, "GL's LightSpeed1000™ hardware platform (PCIe Card and USB Pod) is capable of unchannelized or concatenated mode, permitting access to PPP and ATM networks, and wire-speed processing on quad optical ports for functions such as wire-speed recording and wire-speed playback of Unchannelized and Channelized ATM, PoS, and RAW Traffic."

Important Features

• 2 Channelized OC-3 STM-1 SONET/SDH interfaces per Lightspeed1000™ card – for monitoring both directions
• Channelized ports act as terminal multiplexers and demultiplexers
• Allows direct access to anything and everything on SONET / SDH – Framing and Payload, including structured traffic (T1, E1, STS-1, DS3 etc) or unstructured traffic (ATM, PoS, etc).
• Supports any combination of DS0/64/56/16/8 kbps fractional T1/E1, and N x T1/E1 interface definitions (a total of 126 E1s or 168 T1s – each port supporting 84 T1s or 63 E1s),
• Future support for direct access to all E3s and T3s without hardware modification -software revision only
• Pluggable SFPs allow Single-mode (SM), and Multi-mode (MM) fiber optic non-intrusive tap
• API for Microsoft^® Windows^® and Linux operating Systems to develop user specific applications

Key T1 / E1 specific features

• Comprehensive protocol analysis and emulation – HDLC, SS7, ISDN, CAS, PPP, Frame Relay, ATM and more
• Analysis of DS0s for frequency, power level, spectral display, listen to channel
• GL's proven WCS high level remote interface
• All protocols analyzers can be used with GL's NetSurveyorWeb™

Supported SONET Mappings

• STS-3/OC-3 --> STS-1 --> VT-Group --> VT2 --> E1
• STS-3/OC-3 --> STS-1 --> VT-Group --> VT1.5 --> T1

Supported SDH Mappings
