Saint-Petersburg 2013 The Hardware Engineering Department
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 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 Embedded Systems Real-time Systems Fault-Tolerant Systems Custom design from scratch Optimized algorithms Specialized architectures Balanced HW & SW solutions Advanced engineering technologies Electronics Engineering

NGN: Next Generation Network Example of multiservice IP-based network topology 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

PON: Passive Optical Networks 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 или GEPON (Ethernet PON) IEEE 802.3av -- 10GEPON (10 Gigabit Ethernet PON) Technology solving the “last mile” problem GEPON optical line terminal (OLT) developed by Lanit-Tercom: 4 GEPON downlink ports supporting up to 254 terminals (ONU) connected to each one 4 uplink ports of Gigabit Ethernet (1000 BASE-TX) standard plus 2 uplink ports of Gigabit Ethernet (1000 BASE-X SFP) standard Supports the wide list of telecom technologies: Ethernet, PON, SNMP, TCP/IP, IGMP, RSTP, QinQ. 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.

Digital Video Broadcasting Strong signal feedback, multi-path and echoes, especially in urban area Heavy constraints for the retransmission delay Need for self-adjustment to the channel variations Interference between base stations and repeaters Signal distortions from amplifiers nonlinearity Engineering challenges in the single-frequency video broadcasting networks (SFN): 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 and dependable computer: The true TMR (2oo3) architecture with packet-level voting Fault-Tolerant Computer “OVK” OVK modules in the debugging crate 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 reliability diagram MTBF > 300 Mil. Hours!
