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

NGN node

The NGN nodes “Nickel” are developed by Lanit-Tercom

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” problemGEPON 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.

• Out-of-band service channels, alarm call

Advanced features

ACM: Adaptive coding and modulationCCDP: Сo-channel dual-polarization transmission

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

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
