Gaithersburg, Maryland (BUSINESS WIRE) 5 November 2011
GL Communications Inc. is a leading provider of PC-based test, analysis and simulation products and consulting services for the telecommunications industry broadcast worldwide today announced the availability of the Linux driver support for T1 and E1 cards universal OC-3 / 12 STM 04.01. In conversation with media persons, said Vijay Kulkarni, CEO of the company? Internet as we know it today would not be without “open source”, a model that exists on the joint development of free software available to everyone based. Its roots lie in science, higher education and universities where free and open exchange of ideas (and software) is a way of life. The Internet of open source, such as Linux, Apache, TCP / IP, DNS, PHP is turned on, the list is endless.?
He added:? Linux is open source shining star. Sun GL, and Linux drivers and APIs for our banner products! Because our cards unique features not available with other industry-standard cards have, customers can custom applications faster and cheaper. We currently have Linux drivers and APIs for our T1 E1 and STM OC-3/12-1 universal / 4 cards. All functions of the device is exposed through the API. In addition, many software features based on the system that are available, including the development of complex applications.
Details
Linux API and driver
? After implementation of our “GLComIFC” from Windows to Linux, drivers and all hardware API provides functions for both T1 and E1 cards OC-3/12 STM-1 / 4
? An API toolkit provides examples of how to access the raw data, enable / disable logging, set the clock mode, get / set alarms, loopbacks
T1 E1 Universal Card provides examples:
? HDLC implementation of multi-timeslot intervals alone or streams, ATM cell delineation and more
? Delay implementation and BERT, current recording / playback at the sub-interval, and multi-interval schedule
? Working with multiple cards in one PC, remove the application of methods of frame relay in the software, the access mask and pulse jitter measurements / add the entry and exit of VF VF
? Adjustments for special cabling as Puerto de la Cruz by the transfer of Puerto de la Cruz, Bridge, and the monitor
? Access to the logic of insertion errors, logical access to Tx frequency deviation
OC-3/12 STM district are examples of (LightSpeed1000 card?)
? Works on Win32 and Linux using C / C + + interfaces (VS2005 and above the windows)
? Recording / playback speed cable (gigabit / s)!
? Scrambling / no load-Management encrypts ATM / POS / transparent management methods and recovered clock
line loop / diagnosis / PL3, Rx End / monitor support ATM cell control the start, hardware, data filtering
? Based hardware and software performance indicators, information SFP, alarm monitoring (OOF, LOF, LOS, AIS, RDI, APSBF)
? ATM error counter (GDP, REI, HEC), Point of Sale counter error (GDP, REI, Rx / Tx abort, min / max length)
? BERT hardware, POS FCS of 32 bits, 16 bits FCS and non-support, hardware outputs addition / stripping FCS-byte configuration before, and the section line fault lay, HCS errors
