155-Mbps concatenated POS interfaces on a single card.
Channelized Line Cards
In channelized line cards, each physical port can be configured to support multiple interfaces, or
channels. Each channel is treated as a physical interface by the Cisco IOS software. Most of the
functionality available on standard interfaces is also available on channelized interfaces. For example, it
is possible to run different encapsulations on each of the different channels. Advanced functionality such
as extended Access Control Lists (ACLs) and Committed Access Rate (CAR) can also be applied to
connections using channelized interfaces.

Channelized 4-port OC-12/STM-4
The channelized 4-port OC-12/STM-4 to DS-3/E3 line card supports both SONET and SDH framing and
provides DS-3/E3 aggregation for the Cisco 12000 series Internet router. For SDH, both AU-3 and AU-4
mappings are supported. The line card interfaces with the Cisco 12000 series Internet router switch
fabric and provides four OC-12/STM-4 duplex SC single-mode intermediate reach optical ports. Each
of these ports can be configured with up to 12 channelized interfaces.
