Motorola Inc. has announced the release of the C-3e 3Gbps network processor, Q-3 traffic management coprocessor, and TDM channel adapter to address the requirements of access networking equipment such as 2.5G/3G wireless infrastructure, media gateways, cable modem termination systems, DSLAMs, and multiservice access platforms.

A member of the C-Port product family, the C-3e delivers >3,000MIPS and offers full software programmability. It uses eight channel processors for physical interface connections, packet/cell data parsing, and protocol transformation. The channel processors also integrate Ethernet MACs and SONET/SDH framers.

The network processor also includes eight services processors that can be used concurrently for processing more advanced functions such as SARing, traffic management, and encapsulated protocol processing. Built-in coprocessors can be use to accelerate classification, buffer management, and traffic management tasks.

The C-3e's architecture supports multiprotocol programmability including AAL-1, AAL-2, AAL-2 SSSAR, AAL-5 SAR, ATM TM 4.1, IMA, IPv4, IPv6, UDP, and RTP.

The Q-3 traffic management coprocessor offers scalable IP and ATM traffic management for highly channelized designs. It provides ATM TM 4.1 and IETF Diffserv-compliant policing, shaping, monitoring, and scheduling of up to 64k flows/connections.

The coprocessor can support up to 4,096 virtual channels that can be rate limited to conform to a particular downstream link bandwidth or have minimum bandwidth guarantees with weighted fair sharing on the excess bandwidth available at the virtual port or interface.

For aggregating TDM interfaces into the C-3e, Motorola's TDM Channel Adapter can be used to 8 to 16 TDM lines consisting of multiple, independent, logical channels into a single C-3e channel processor.

This enables the C-3e to support aggregation of up to 256 T1/E1 lines with up to 2,048 logical channels of HDLC, ATM, and transparent data.

Software support for the C-3e is provided via the C-Ware Software Toolset v2.1, which allows OEMs to start coding and simulating C-3e applications.

The C-3e and Q-3 processors are priced at $225 and $235, respectively for 10,000-unit quantities.
