QUADRILLIUM's mission is to develop and propose Telecommunication equipments to the market

Quadrillium founders come from major telecommunications companies. They totalize more than 10 years in R&D in networks equipments with a special focus on products for the local loop.

Today, demands are for low cost services.
To fulfill with these demands, carriers and companies are looking to Ethernet technology to reach the objectives.
TDMoIP* also called - circuit emulation services over packets -  take place in this move allowing Ethernet use to build links using traditionally SONET/ATM technology.

In compensation for expected gains, due to the fact that Ethernet networks have no synchronization, some unexpected link failures can impact on quality of communications.

Novelty introduced by Quadrillium products help to compensate failure links, it is called RTSoE " Real Time Streams over Ethernet".
This concept allows the transport of native synchronous streams by means of L2 & L3 Ethernet (OSI layer). Clock signal coming from master source interface (E1/T1, X21,...) is sent to remote site, source clock variations are fully transmitted and restore to remote.

This special feature (Quadrillium patent) improve the quality of services (QoS) needed by applications using synchronous interfaces (E1/T1, X21,...) and remain economically very attractive against solutions based on PDH/Sonet and ATM.

Because networks are sometimes routed and sometimes switched, Quadrillium equipments include TDMoIP or TDMoVLAN algorithms to always keep the best of the technology in use.
