Tata Elxsi offers services in firmware and device driver development for network adapters and SoC designs for a wide variety of physical interfaces including USB, 1394, Ethernet, Token Ring, T1/E1, DS-x, OC-x/ STM-x, xDSL, cable modem, and RF interfaces.

Backed by decade long involvement in designing networking devices, we have strong skills in developing Layer-1 protocols and bridging software for a wide range of devices deployed in edge, access, and carrier networks.

Success stories

	Developed ATM SAR driver for an SoC with ATM library and wrapper functions to integrate the driver with a proprietary 3rd party module
	Developed firmware on VxWorks to develop SAR and CPCS layers for AAL5 for an ARM7 based SoC
	Developed firmware to bridge HDLC interface and an ATM-ADSL network in a CPE for transferring HDLC frames over ATM (AAL5)
	Designed and implemented LAN Emulation drivers based on NDIS 2.0/3.0 architecture to allow communication across the ELAN boundaries without a router
	Designed and developed HDLC driver, S/T interface drivers, RS232 serial port driver, Line transceiver/U-interface driver, and voice and data port drivers for ISDN signaling
	Developed ISDN protocols consisting of HDLC driver, LAPD (Q.921), LAPB (ISO 7776), ISDN Call Control (Q.931), CAPI 2.0 APIs, and embedded ISDN application on RZK RTOS
