  1. The Hardware Engineering Department Saint-Petersburg 2013

  2. HW engineering department Department facts • Presented in the company structure since the year of foundation, 1991 • Over 150 R&D projects done • Over 50 records in the client list • 45 experienced HW and SW developers, graduated as MsCS, MsEE or PhD • From 5 to 10 project groups run in parallel Services • Design, implementation and support of custom-made computing, networking, controlling and other electronic systems

  3. Expertise Electronics Engineering • Embedded Systems • Real-time Systems • Fault-Tolerant Systems • Custom design from scratch Optimized algorithms Specialized architectures Balanced HW & SW solutions Advanced engineering technologies • In focus: Telecommunications • Wired and Wireless, short and long distance • From end-user terminals to Metro level equipment • Copper lines, classic optics, passive optics, radio channels • Internetworking between Ethernet, ATM, FDDI, GPON and more • Digital video broadcasting • Compliance to standards plus unique features on demand • Our own implementation of telecom protocols, optimized to the hardware platform and the network environment

  4. Metro-level network based on ATM technology • ATM technology advantages: • Guaranteed QoS • Optimal usage of the channel bandwidth • Emulation of synchronous links over ATM • Flexible management of the virtual channels • All the classes of services and adaptation layers introduced by ATM standard are natively implemented • Gateways provide simple connection of various terminal devices • Additional protocols supported: • MPOA - multiprotocol encapsulation over ATM • CES - circuit emulation services (E1 over ATM) • IPOA - IP over ATM; • ATM security specification; • xDSL, DSLAM integration

  5. NGN: Next Generation Network NGN is a multiservice network based on IP protocol and integrating the voice, video and data transmission services • The system “Nickel” is NGN node providing voice, video and data services over ATM or SDH backbone networks • It includes a set of modules: • “TK” - as Ethernet gateways • “TE”– as TDM/VoIP gateways • “TA” – as ATM gateways • “TS” - for backbone SDH links Example of multiservice IP-based network topology

  6. PON: Passive Optical Networks Technology solving the “last mile” problem • GEPON optical line terminal (OLT) • developed by Lanit-Tercom: • 4 GEPON downlink ports supporting up to254 terminals (ONU) connected to each one • 4 uplink ports of GigabitEthernet (1000 BASE-TX) standard plus 2 uplink ports of GigabitEthernet (1000 BASE-X SFP) standard • Supports the wide list of telecom technologies: Ethernet, PON, SNMP, TCP/IP, IGMP, RSTP, QinQ. • PON(Passive Optical Networks) is a new technology of data transmission over optical tree-like structures using only passive splitters in the nodes. • PON uses active devices only at the provider site(OLT, Optical Line Terminal) and subscriber site (ONU, Optical Network Unit). • Applied standards: • ITU-T G.983 -- APON (ATM Passive Optical Network) BPON (Broadband PON) • ITU-T G.984 -- GPON (Gigabit PON) • IEEE 802.3ah -- EPON илиGEPON (Ethernet PON) • IEEE 802.3av -- 10GEPON (10 Gigabit Ethernet PON) • Next generation of the PON OLT • (under development by Lanit-Tercom): • 4 IEEE 802.3av (10GEPON)ports • 80 Gbit/s - the total communication performance • Supports GPON, GEPON and 10GEPON native connectivity in one device.

  7. Microwave-link equipment • IDU“Anterum” user interfaces: E1/E3 (*8/16/32), Gigabit Ethernet (*1/2/4), STM-1 (*1/2/4) • User interfaces commutation: each to each • Configuration and redundancy: • Support of 1+0, 2+0, 1+1 architectures with frequency or spatial separation • Fast switching to redundant channel • Hot swap of modules • Out-of-band service channels, alarm call ODU ODU • Microwave link performance: • 6 – 38 GHz: 400 Mbps / 56 MHz(QAM-256) • 71 - 86 GHz: 10 Gbps / 5 GHz (QAM-16) Advanced features IDU IDU CCDP: Сo-channel dual-polarization transmission ACM: Adaptive coding and modulation

  8. Digital Video Broadcasting Engineering challenges in the single-frequency video broadcasting networks (SFN): • Strongsignalfeedback, multi-pathandechoes, especiallyinurbanarea • Heavy constraintsfor theretransmissiondelay • Need for self-adjustmenttothechannelvariations • Interference between base stations and repeaters • Signal distortions from amplifiers nonlinearity Solutions by Lanit-Tercom: • Equalizing of the gain-frequency and phase-frequency characteristics based on the instant channel transfer function estimation • Adaptive filtering of echoes and multi-path signal distortions using the original DSP algorithms • Adaptive suppression of narrow-band and impulse noise of any derivation • Automatic linear and non-linear pre-correction of the amplifier stage • Virtual compensation of frequency shifts and precise synchronization subsystem in the receiver

  9. Integrated communication system for trains • Advanced multimedia system inside the high-speed trains: • Combines the infotainment, service and alarm functions • Provides the personal communication between the passenger and the train crew • Personalizes the warning and reminders to the passengers • Improves the communication abilities in critical situations • Delivers useful information and video on demand to every seat equipped by TFT monitor • Provides an internet access from the train LAN via central server

  10. Fault-Tolerant Computer “OVK” Fault-tolerant and dependable computer: The true TMR (2oo3) architecture with packet-level voting • No single point of failure • No single point of recovery • Automatic re-configuration after local faults • 100% error detection level • 100% error localization level • Complete prevention from error propagation OVK modules in the debugging crate MTBF > 300 Mil. Hours! OVK reliability diagram

  11. Embedded SW engineering Embox (Essentialtoolboxforembeddeddevelopment) • Real-time operating system (RTOS) • Open-source: • Distributed with simplified BSD “3-clause” license • Developed especially for embedded systems • Based on highly configurable, modular and safe architecture • Specifications • Multi-platform support (x86, SPARC, ARM, PowerPC, MicroBlaze) • Extremely low resource requirements (from 6 kB image size for SPARC) • Support for the most of widespread network services (including the full TCP/IP stack) and file systems • The Embox development team mainly consists of Lanit-Tercom employees • Total Lanit-Tercom investment to the project since 2009 is over 1M USD http://code.google.com/p/embox/
