EC COST 226

"Integrated Space / Terrestrail Networks" (1990-1995)


Project

LAN Interconnect System


Development Team

Jaoneum Graz, CNUCE, et al


Funding

COST / Local funding


Use

R & D


Status

Operational 93/94 (3 sites)


Transponder

Ku-Band (SMS) using the Olympus Satellite

Ka-Band using DFS-Kopernikus


Access

Symbol-Synchronous TDMA (The modem was developed by Matra Marconi. An experimental MF-TDMA has also been studied. The FODA/IBEA access scheme was developed by CNUCE.)


Speed

2 Mbps TDMA conencted via 384 kbps to H.261 video codecs or optionally CISCO routers with TCP/IP support.


Terrestrial Net Interface

Routed IP from Ethernet using CISCO routers, IP/X.25 was also used in some experiments. FDDI and ATM interfaces have also been studied.


B-ISDN Signalling?

No (Packet interface)


Terrestrial Phys Interface

Cambridge Fast Ring used internally. Interfaces using RS-449 (packet), G.703 (stream). ISDN 2B+D also studied.


Notes

The system was based upon the SATINE network.


Future

Initial support for G.703 via AAL1 has also been demonstrated. An ATM experiment has also started with ESA ASTP-5 funding and will likely be a part of COST 253 "Efficient Network Interconnection via Satellite".
