GL Communications Inc. announced today the release of Linux Driver Support for Universal T1 E1 and OC-3/12 STM-1/4 Cards. Speaking to newsmen, Mr. Vijay Kulkarni, CEO of the company said,” The Internet as we know it today would not exist without open source software, a model based on collaborative software development available free to anyone. Its roots are in academia, colleges, and universities where open and free exchange of ideas (and software) is a way of life. The Internet is powered by open source, like Linux, Apache, TCP/IP, DNS, PHP, the list is endless.”

He added, “Linux is the shining star of open source. So GL is developing Linux drivers and APIs for our flagship products! Since our cards have unique features unavailable with other industry standard cards, customers can now build custom applications faster and cheaper. Currently, we have Linux drivers and APIs for our T1 E1 Universal and OC-3/12 STM-1/4 Cards. All of the functionality of the hardware is exposed through the API. In addition, many software based functions are available that ease even the most complex application development.”

Details of Linux APIs and Drivers

* Having ported our GLComIFC from Windows to Linux, the driver and API expose all features of the hardware for both T1 E1 and OC-3/12 STM-1/4 Cards

* An API Toolkit provides examples how to access the Raw Data, Set / Reset Registers, Set Clocking Modes, Get / Set Alarms, Loopbacks

* For T1 E1 Universal Card, examples are provided for:

o Implementing HDLC on single timeslots or multitimeslot streams, ATM cell delineation and much more

o Implementing Delay and BERT, Record/Playback on sub-timeslot, timeslot, and multi-timeslot streams

o Working with multiple cards in a single PC, Implementation methods for Frame Relay in software, Accessing Pulse Mask and Jitter measurements, Dropping / Adding VF Input and VF Output

o Configuring special cabling options like Cross Port Thru, Cross Port Transmit, Bridge, and Monitor

o Access to Error Insertion Logic, Access to Tx Frequency Deviation Logic

* For OC-3/12 STM-1/4 (LightSpeed1000™ Card), examples are provided for:

o Works on Win32 and Linux with C/C++ interfaces (VS2005 and above for windows)

o Record / Playback at Wirespeed at (Gigabits/sec)!

o Scrambling / Non-scrambled payload management in ATM / POS / Transparent modes with Internal and Recovered Clock management

o Loopback Line / Diagnostic / PL3, Rx Terminate / Monitor support, ATM Idle Cell Control, Hardware Data Filters
