Cisco PA-MC-T3

The PA-MC-T3 Multi-Channel T3 port adapter is available on Cisco 7200 series routers, on second-generation Versatile Interface Processor (VIP2) in Cisco 7500 series routers, and on Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP) and 7000 Series Chassis Interface (RSP).

The PA-MC-T3 has one channelized T3 high-speed serial interface that provides access to services at T1 (1.544 Mb) data rates, transferring data bidirectionally. This port adapter divides the T3 signal stream into 28 T1 lines that can be further divided into the 64 kbps level, up to a total of 128 channels.

The PA-MC-T3 port adapter provides the following key benefits:

•Reduced cost—High levels of integration eliminate the cost of external CSU/DSUs and multiplexers. Channelization allows customers to lease fewer and more cost-effective lines from service providers.

•Simplified management—Management of the internal CSU/DSUs is handled through the router. No cabling complexity is associated with large installations of external boxes.

•Flexible provisioning—A single port can be used for up to 128 64K, Nx64K, FT1, and T1 connections to IP and Frame Relay networks. As network needs change, bandwidth can be reallocated without moving any cables.

•Increased slot utilization—Double to quadruple port density over previous port adapters (up to 56 T1 lines per Cisco 7500 slot) means increased value for each router slot.

•Increased rack space utilization—Elimination of external CSUs frees up rack space. High port density reduces the number of routers required for large installations.
