2 STAR TAP Waves Overview 01/06/05GN2Global Crossing Proprietary 1727: Giovanni Pittoni, Monument to Isaac Newton Waves History: Early Wave Experiments

3 STAR TAP Waves Overview 01/06/05GN3Global Crossing Proprietary Optical Wavelength Services Only 1 year on the market: Monday April 24, 2000, Rochester, N.Y. Global Crossing (NYSE:GX) Introduces Wholesale Optical Wavelength Service Tuesday May 9, 2000, Las Vegas, NV Level 3 Communications, Inc. (Nasdaq:LVLT) today announced the introduction of Global Wavelength services. Wave Definition (GX): 2.5 & 10 Gb/s optical route through the network via an interconnection at the optical multiplex systems Note that: –Full transparency not always guaranteed –Wave may actually be muxed into higher aggregate stream (i.e. 40 Gb/s)

4 STAR TAP Waves Overview 01/06/05GN4Global Crossing Proprietary PREFERRED: Overhead Transparent Carrier Network Customer Mesh Network Can the full 2.5 G capacity be used for IP? Packet Customer view: End-to-end link: Protection handled at IP multiplex layers Protection features of SDH/SONET are generally unexploited. Transparent end-to-end link allows in-band TMN signaling Signal protocol must be consistent (i.e. SONET OR SDH)
