Voice, data, and video traffic is exploding as smartphones, IP TV, video streaming, and "cloud" based services takeoff. A majority of the backbone transport for these applications continues to be SONET and SDH optical transmission networks. A dominant protocol for IP transport is PoS (Packet over SONET) and another is ATM (Asynchronous Transfer Mode). Both schemes are packet based, with ATM using fixed size packets of 53 bytes called "cells", and PoS using variable packet sizes closely matching to Ethernet frames.
SONET and SDH transmission network also continue to be used for conventional channelized traffic – carrying many TDM T1, E1, T3, and E3 pipes.
GL's LightSpeed1000™ hardware platform (PCIe Card and USB Pod) is capable of OC-3/12 and STM-1/4 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.
Two ports out of the 4 ports are meant for SONET/SDH unchannelized and unframed data. The remaining two ports are meant for SONET/SDH channelized data of carrying many independent unframed/framed T1, E1, T3, and E3 streams.
The LightSpeed1000™ comes with software for overall monitoring, BERT, emulation, and protocol analysis with a price tag that compares very favorably with similar test instruments at three times the price.
In an OC-3/STM-1, all 84 T1s or all 63 E1s can be identified and processed in transmit and receive modes. In an OC-12/STM-4, all 336 T1s or all 252 E1s can be identified and processed in transmit and receive modes. The hardware can also be easily configured / programmed for delaying of ATM Cells or PPP packets.
GL Communications has the following variants of OC-3/STM-1 and OC-12/STM-4 Analyzers:
- Quad OC-3/STM-1 and OC-12/STM-4 PCI-Express card (Windows® 7 and above 32-bit, 64-bit)
- Portable Quad OC-3/STM-1 and OC-12/STM-4 Unit (Windows® 7 and above 32-bit, 64-bit)
The card's multiple connectivity using PCIe, Gigabit Ethernet (GigE), USB 2.0 and onboard DDR2 memory makes it suitable for many applications.
Multiple cards are possible in a PC for analysis of four or more directions simultaneously. USB 2.0 interface is used to connect with a Notebook PC for portability. GigE Ethernet ports for testing RAW, BER, RFC2544, RAW SONET/SDH, and Ethernet bridge applications. The hardware is firmware FPGA based making it easy to upgrade in the field for application versatility.
A unique feature of the card is the capability to capture, transmit and process at wirespeed to/from applications and hard disk on all interfaces. An API Toolkit allows users to develop specialized applications.
