    The Cisco® Carrier Packet Transport (CPT) Product Family with CPT600, CPT200 and CPT50 Series sets the industry benchmark as a compact carrier-class converged access and aggregation platform for Unified Packet Transport architectures. Cisco CPT product family represents an exciting new paradigm in the world of Packet Transport with exceptional pay as you grow scalability, carrier-class reliability, incredible flexibility, and TDM like ease of packet service provisioning, OAM and protection capability.

    Product Overview

    The Cisco CPT 50 introduces architectural innovations to the CPT product family for building access and aggregation Packet Transport networks and redefines the network economics and management to provide exceptional CapEx and OpEx advantages.  The Cisco® CPT 50 is a compact and operationally simple, yet highly scalable and flexible platform optimized for delivering TDM like Ethernet Private lines as well as multipoint capabilities for Business, Residential, Mobile Backhaul, Data Center, and Video Services. Its unique satellite architecture is designed to scale, simplify and enhance the operational and deployment aspects of service-delivery networks. The Cisco CPT 50 Series behave as remote line cards for CPT 600 and/or CPT 200, together forming a distributed modular system. This architecture enables physical topologies with the flexibility and benefits of collocated and remote deployments.

    Some highlights of this next-generation platform are:

       The Cisco CPT 50 Series acts as a satellite in a distributed modular architecture and terminates various services. The satellites are purpose built to achieve multiple goals to basically reduce both CapEx and OpEx costs:

         Do more with the same by increasing density of service interfaces per chassis by a factor of 3x to 10x

         Deployment flexibility as satellites can be collocated with the main chassis or located in a remote location up to 80km away

         Simplified operations: One single point of management and policy enforcement using upstream CPT 600 and CPT 200

         Significantly reduced space and power needs with industry leading port density

       The Cisco CPT 50 supports unprecedented port density in 1 RU space with 44 SFP based ports (10/100/1000 Mbps) and 4 SFP+ based 10GE ports.  CPT 50 introduces a license based pay as you grow model for Ethernet ports allowing customers to optimize current CapEx, while having capacity to grow in the future without a fork lift upgrade. Added with ITEMP temperature rating, the platform can be not only deployed in temperature controlled central offices but also in harsher locations like outside plants.

       In a metro area, service providers fan out many Ethernet ports for service delivery but the management of such a distributed solution is complex. The Cisco CPT50 Series solves this problem by centralizing the management of a distributed system. The Cisco CPT 50 is managed as a virtual line card of CPT 200 or CPT 600. The management operations for CPT 50 such as provisioning, software download, platform discovery and database backup are performed at CPT200 or CPT 600. The virtual CPT50 can be collocated with UST200 or CPT600 using cheap 10G copper SFP+ pluggables or can be remotely located using long reach 10G SFP+ pluggables. The satellite architecture can be extended to solve many kinds of access needs like Ethernet, TDM or others with a common backhaul architecture in effect saving need for different architectures for each kind of access.

       Hardware supported with timing outputs for BITS and TOD/PPS standards-based line-interface functions for delivering transport-class network timing, enables support of network-synchronized services and applications such as mobile backhaul and time-division multiplexing (TDM) migration.

    Flexible Ethernet services

      Ethernet Virtual Connections (EVCs): Ethernet services are supported using individual EVCs to carry traffic belonging to a specific service type or end user through the network. EVC-based services can be used in conjunction with MPLS-based L2VPNs and native Ethernet switching deployments.
      Flexible VLAN classification: VLAN classification into Ethernet flow points (EFPs) includes single-tagged VLANs, double-tagged VLANs (QinQ and 802.1ad), contiguous VLAN ranges, and noncontiguous VLAN lists.
      IEEE Bridging: The line cards support native bridging based on IEEE 802.1Q, IEEE 802.1ad, and QinQ VLAN encapsulation mechanisms.
      Resilient Ethernet protocol (REP): The REP provides a resilient, fast-convergence mechanism for aggregating and connecting to Ethernet-based access rings.


    L2VPN services

      MPLS-TP Circuit with Ethernet over MPLS-TP (EoMPLS-TP): EoMPLS-TP transports Ethernet frames across an MPLS-TP LSPs using pseudowires. Individual EFPs or traffic from an entire port can be transported over an MPLS-TP network using pseudowires to an egress interface or sub-interface.
      Virtual Private LAN Services (VPLS): These services are included in a class of VPN that supports the connection of multiple sites in a single bridged domain over a MPLS-TP network. VPLS presents an Ethernet interface to customers, simplifying the LAN and WAN boundary for service providers and customers, and enabling rapid and flexible service provisioning, because the service bandwidth is not tied to the physical interface. All services in a VPLS appear to be on the same LAN, regardless of location.
      Pseudowire redundancy: Pseudowire redundancy supports the definition of a backup pseudowire to protect a primary pseudowire in case of failure.
      Multi-segment pseudowire stitching: Multi-segment pseudowire stitching is a method for interworking two pseudowires together to form a cross-connect relationship.



      Span is a technique of replicating the ingress or egress frames in a specific port to a specified list of destination ports. It is a monitoring feature used to monitor the traffic that is coming out of a port or an EFP. The monitored traffic can be used to debug the network and can also be used by law enforcement agencies.


    High Availability

      MPLS-TP: 1:1 MPLS TP LSP delivers protection switching for networks with sub-50ms APS switching for link, node, path failures.
      Bidirectional Forwarding Detection (BFD): BFD is a detection protocol that is designed to provide fast forwarding path-failure detection times for all media types, encapsulations, topologies, and routing protocols
      802.3ad Link Aggregation Bundles: The line cards support a bundle of multiple links to provide added resiliency and the ability to load balance traffic over multiple member links.



      IGMP v2 and v3 snooping: This Layer 2 mechanism efficiently tracks multicast membership on an L2VPN network. Individual IGMP joins are snooped at the VLAN level or pseudowire level. In residential broadband deployments, this scenario enables the network to send only channels that are being watched to downstream users.
      Multicast VLAN Registration (MVR): MVR optimizes the control plane (IGMP) load between the router and switch. MVR feature enables switch to aggregate different JOINs received on different VLANs (from the receivers) into one JOIN (on a single VLAN, which could be the same as or different from the VLANs of the receiving ports) towards the router. The switch then distributes (replicate) the received content into the relevant ports.


    Ethernet OA&M

      Connectivity Fault Management (CFM) Ethernet layer OAM protocol provides end-to-end provider edge (PE to PE) and/or customer edge to customer edge (CE to CE) fault management. CFM includes proactive connectivity monitoring, fault verification, and fault isolation for large Ethernet metropolitan-area networks (MANs) and WANs. CFM is defined by IEEE 802.1ag standard.
      Ethernet Link OAM is a protocol for installing, monitoring, and troubleshooting Ethernet metropolitan-area networks (MANs) and Ethernet WANs. It relies on an optional sublayer in the data link layer of the Open Systems Interconnection (OSI) model. Ethernet Link OAM is defined by IEEE 802.3ah standard.
      Remote Ethernet Port Shutdown.  The Remote Ethernet Port Shutdown replicates a local link failure over an EoMPLS pseudowire to a remote link shutdown the remote Ethernet port down.   Bot UNI interfaces connected to the EoMPLS pseudowire will shutdown in the event of a pseudowire failure.
      ITU Y.1731 Fault Management and Delay Management.  The ITU-T Y.1731 feature provides OAM functions for fault management and performance monitoring functionality for service providers in a large network.  ITY Y.1731 includes Ethernet Alarm Indication Signal (ETH-AIS), Ethernet Remote Defect Indication (ETH-RDI), Ethernet Locked Signal (ETH-LCK) functionality for fault detection and isolation.  ITU Y.1731 Delay Management (DM) provides a standard Ethernet PM function that includes measurement of Ethernet frame delay and frame delay variation.



      IP/MPLS OA&M: LSP Ping & LSP Trace Route
      Pseudo-Wire: Virtual Circuit Connectivity Verification (VCCV), Ping, Traceroute, Static Status Message to LDP Status Message Translation
