Frame Relay and ATM technologies allow to construct any wide area network in the star topology, with very high quality parameters.

Why Frame Relay / ATM?

• Traditionally reliable –FrameRelay and ATM are mature, stable and well standardized technologies,
• Quality – extensive QOS and COS mechanisms,
• Security - Built-in connection protection mechanisms.

Technical specifications:

Frame Relay:

• transfer rate up to 45 Mbps,
• minimum transfer rate guarantee – CIR,
• maximum transfer rate – EIR,
• ability to combine numerous virtual circuits in a one physical connection,
• QoS and CoS mechanisms.

ATM:

• QoS and CoS mechanisms,
• Isochronic transmission support (voice, video, HDTV) with the delay not higher than 10 ms.
