Data Sheet

Cisco 10000 Series Six-Port

Channelized T3 Line Card

The Cisco 10000 Series Six-Port Channelized T3 line card sets a new standard for flexibility, scalability, and price/performance in the T1 and T3 aggregation market. The line card supports six T3 physical connections with each T3 capable of supporting a full "clear-channel" DS3 or six ports of DS3 channelized down to DS1 or DS0.

Key Benefits

Flexibility to Add, Modify, and Enhance Services without Changing Your T3 Connection

The Cisco 10000 Series Six-Port Channelized T3 line card is capable of supporting a variety of T3, NxT1, T1, FT1, and DS0 configurations on each of the six ports of every module. This flexibility enables customers to easily increase bandwidth from DS0 up to a full clear-channel DS3 to support new software

Scalability to Increase Services and Grow the Network

With the ability to scale from 168 DS1s to 6048 DS1s, the Cisco 10000 Series provides service providers with industry-leading scalability that enables them to add more customers and services without deploying additional routers in the point of presence (POP).

The Cisco 10000 six port CT3 line card enables service providers to distribute costs over the largest number of ports, reducing the overall cost per port.

Table 1 illustrates the densities of the Cisco 10000 with the six port CT3 line card.
