slide4

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
slide5

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

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.
slide7

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)

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
slide9

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
slide10
