Infrastructure
With a state-of-the-art telephony and data network (based on both digital PSTN switches as well as an IP-Multimedia-Subsystem-IMS platform) together with more than 35,000 kilometres of optical fibres, numerous satellite, underwater and terrestrial international links with all corners of the globe, coupled with products based on international standards, OTE offers modern, quality communications to the Greek people, even to those residing in the most distant and inaccessible locations of the Greek territory. From 2008 to 2011, the company invested more than 500 million euro in networks and technological infrastructure.
Access Networks
OTE’s access network is mainly based on copper (with over 5.3 million pairs) and on optical fibres that will gradually and steadily replace the copper network, according to our NGA (Next Generation Access Network) investment roadmap.
Greece’s entire broadband network relies on OTE’s access network (for all services provided by OTE and all alternate providers).
The supported technologies are:
ADSL/ADSL2/ADSL2+:
- Utilizing the continually expanding OTE’s network, increasing geographical and population coverage
- With over 1.1 million active connections
- With approximately 2,300 points of presence (PoP) throughout Greece, over 2,000 of which are located outside Attica
- Approximately 1.8 million installed ports
- With access speeds of up to 24 Mbps in over 1,230,000 installed ports, with the option for IPTV services in over 1,550 points of network presence (PoPs).
There are also approximately 1.6 million active Unbundled Local Loops (ULLs) utilized by the alternative Operators.
NGA with FTTC/VDSL2 Architecture:
- Until 31 December 2011, we will have completed the installation of equipment that will provide 30 & 50 Mbps services at the following areas: Zografou, Alexandroupolis, Serres, Komotini, Xanthi, Voula, Vouliagmeni, Kalamaki and Terpsithea / Glyfada.
SATELLITE BROADBAND INTERNET:
- Broadband internet via satellite from OTE’s subsidiary, Hellas Sat
- Provision of satellite broadband internet to over 600 isolated locations in the Country
- New Hellas SAT net! Home service for permanent and unlimited internet access in areas where there is no terrestrial network infrastructure or other telecommunications means
Core Networks
OTE’s Core Networks use entirely optical fibres. Currently, OTE’s new transmission network has 1,960 NG-SDH nodes, 14 DWDM local and national rings with a total capacity that exceeds 2.7 Terabits/s. Moreover, we offer IP over SHD for the entire transmission network.
In the Metropolitan areas the Metro Ethernet network is being expanded (with even higher data transmission speeds, as well as support/provision of advanced applications).
New Technologies
- IMS: In the framework of OTE’s network transformation (Next Generation Network-NGN), we have completed the installation and integration of the IMS platform that offers advanced voice and multimedia services (Presence, Messaging, Self-Care Portal) with reduced cost, as it is based on Voice-Over-IP (VoIP) technology and a centralised architecture.
- IPTV: A Interactive-TV Content Delivery Platform, that can distribute its content to over 1,550 points of presence (the majority of which is outside Attica) that correspond to 1,011,040 ports (of which 658,754 outside Attica) is already in place within OTE’s network infrastructure.
- SATELLITE Pay-TV: OTE has started offering a satellite-based subscription television service (OTE-TV) via the Eutelsat satellite, having recently installed a full Head-end with multiple HD channel capability for this service.
- NGA FTTB/H-GPON: In the process of transforming its access network, OTE has implemented a pilot program using a fibre-to-the-building network architecture, mainly in industrial areas. The new Access Network uses Point-to-MultiPoint architecture compatible with the Gigabit Passive Optical Network (GPON) technology capable of 100 Mbps access speeds.
