  Sept 2004 - Jun 2006

  Development engineer

  (2 years) (wireless, DECT- L3, embedded, C, Assembly)Overview of WorkEnvironment : C, ADSP218x assembly languageProcessor : ADSP 2188m Target System : CorDECTMy Role : Requirement Gathering, Design, development and unit testing.Description : CorDECT is a complete wireless access solution for new and expanding telecommunication networks with seamless integration of voice and internet services. CorDECT is made using ETSI DECT protocol. FRS100 is the one of the subsystem of the corDECT which will be used in the subscriber premises. The module, which I have worked on, is the voice part (network layer, IWU layer) and peripheral interface part (which includes OnHook/OffHook detection, Generating Ringing Cadence, Polarity Reversal, and Metering) in DECT subscriber terminal (ST). 1. Projects on Fixed Remote Station (Subscriber Terminal) FRS100:- Network Scheduler for Call Processing Location Registration Implementation AOV (Always On voice) Service Call State Machine FSK CLIP Stack Implementation in R2 and V5 BER Implementation and dumping result to Operator console Tripple beep in case of no channel Wrote device driver for SLIC device Code Optimization and C to Assembly conversion2.
