The Internet is an electronic agent for commerce, entertainment, communication, and information retrieval. New network-enabled intranet and Internet applications and services are accelerating an exponential growth in network traffic, resulting in increased demand for available and guaranteed bandwidth.
In response to higher bandwidth and capacity demand, carriers and Internet service providers (ISPs) are now offering DS-3 (45 Mbps) or E3 (34 Mbps) dedicated access connections. For service providers looking to simplify the deployment and delivery of DS-3 or E3 leased-line services with Cisco® 12000 Series Internet routers, Cisco Systems® offers the following set of line cards:
The Cisco 12000 Series 6- and 12-port DS3 time-division multiplexing (TDM) line cards simplify the deployment of DS-3 services (Figure 1).
The Cisco 12000 Series 6- and 12-port E3 TDM line cards allow the delivery of E3 leased-line services on the Cisco 12000 Series router (Figure 2).
