 PA-MC-T3, Cisco PA-MC-T3, 1 port multichannel T3 port adapter
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.
•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.
Note: The aggregation of multiple T1 lines for higher speed (called inverse multiplexing or bonding) is not supported. There is support for 56-kbps timeslots.
