Cisco 12000 Series Dynamic Packet Transport Line Cards
The Cisco
®
12000 Series Dynamic Packet Transport (DPT) line cards offer packet-optimized optical transport solutions by combining the
bandwidth-efficient and services-rich capabilities of IP routing with the bandwidth-rich, self-healing capabilities of fiber rings to deliver
fundamental cost and function advantages over existing solutions. DPT rings are dual, counter-rotating fiber rings. Both fibers are used
concurrently to transport both data and control traffic. DPT rings run on a variety of transport technologies, including SONET/SDH,
wavelength-division multiplexing (WDM), and dark fiber. DPT provides carriers with the flexibility to operate packet rings over their embedded
fiber transport infrastructure as well as an evolution path to packet-optimized transport for high-bandwidth IP networks.
The Cisco DPT line cards offer the following connectivity options:
●
4-port OC-12c/STM-4c DPT IP services engine (ISE)
●
4-port OC-48c/STM-16c DPT
●
1-port OC-192c/STM-64c DPT
