Newsletter: GL Enhanced Direct T1 E1 Access for SONET SDH
Welcome to a March 2015 issue of GL's Newsletter providing information and insight into our enhanced OC-3/12 and STM-1/4 Analysis and Emulation Platform referred to as LightSpeed1000™. Among its many features is direct access to any or all T1s E1s (84 T1s = 4,032 DS0s, or 63 E1s = 3,906 DS0s) inside the OC-3 STM-1 as seen below.
This compact approach saves power, cost, space, and cables.
GL's LightSpeed1000™ comes with all the necessary software for capturing, monitoring, emulation, and protocol analysis over SONET-SDH links, with a price tag that compares very favorably with similar test instruments at 3 times the price. It supports both Channelized and Unchannelized modes. 2 out of the 4 ports are meant for SONET/SDH Unchannelized and unframed data. The remaining 2 ports can be either SONET/SDH or GigE (future) ports meant for Channelized T1 E1.
The LightSpeed1000™ Card can be installed in a 1U PC appliance or in a portable enclosure as shown below.
GL’s LightSpeed1000™ in Channelized Mode provides simplicity and permits direct DS0 level access to hundreds of T1s and E1s within OC-3 STM-1, 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, interdependent streams of any user-defined capacity can be generated internally, analyzed, and monitored in real-time. For more information on the application, the user can refer to the LightSpeed1000™ in Channelized Mode webpage.
