A Wireline system uses wires or cables to transmit signals instead of air-borne radio frequencies. Wireline based on copper wires was used to provide basic telephony services to the subscribers. Nowadays consumer Wireline voice services have been especially hard hit due to the growth of wireless voice services and increased competition among Wireline service providers.
Revenue from traditional Wireline services will continue a steady decline over the next few years and carriers will have to promote other services to make up the difference. These include IP Telephony, QoS for Internet access, IP VPN, managed security & firewall, and Telco TV."

Also the business expenditures will decline for Wireline voice and data access/transport services due to adoption of Voice over IP and migration to lower-cost data services. However, internet access services for both consumer and business still remain an area of growth.
Business services providers will have to think in a more consultative manner which requires a greater understanding of a customer’s LAN, and a time commitment to seamlessly integrate the LAN and WAN together.
Traditional copper Wireline network can be exploited for broadband services. As software call control replaces circuit switches, it is less expensive to put a network in place and keep it running. Proprietary circuit switch equipment is being replaced with blade computer servers. Soft switches and routers form a significant aspect of the network. Access equipment takes up more of capital expenditure. .

New network architectures make it less expensive to provide network services. New applications provide increasing numbers of revenue streams.
