The following chart summarizes recent quarterly revenues for Wireline Networks:

2003 vs. 2002

Wireline Networks revenues declined 22% in 2003 compared to 2002. This decline was primarily due to a substantial reduction in capital spending by our service provider customers as a result of the continued industry adjustment.

Revenues from the circuit and packet voice portion of this segment decreased substantially in 2003 compared to 2002 primarily due to a substantial decrease in our traditional circuit switching product revenues and also uncertainty related to the impact of the Federal Communications Commission, or FCC, decision regarding the regulation of the availability of unbundled network elements, or UNEs, released on August 21, 2003 and subsequent judicial review and FCC reconsideration of the decision. The substantial decline in our circuit switching revenues was primarily due to the continuing impact of capital spending restrictions experienced by our service provider customers during 2003 and tightened capital markets mainly during the first half of 2003. Revenues from our packet voice solutions increased substantially across all regions except EMEA in 2003 compared to 2002 primarily due to new service provider contracts throughout 2003.

Revenues from the data networking and security portion of this segment decreased significantly in 2003 compared to 2002 primarily due to substantial declines in the U.S. and Asia Pacific and a significant decline in CALA. In these regions, we experienced a decline in demand for our mature products primarily due to the ongoing shift towards IP-based technology.

•32% decline in revenues in the U.S. primarily due to the continuing impact of capital spending restrictions experienced by our service provider customers, tightened capital markets mainly during the first half of 2003 and also uncertainty related to the impact of the FCC decision regarding the regulation of the availability of UNEs;
