Product Overview

The Cisco® Carrier Packet Transport (CPT) 600 sets the industry benchmark as a 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.

The CPT platform has great revenue potential for service providers by providing TDM like Ethernet Private lines as well as multipoint capabilities for Business, Residential, Mobile Backhaul, Data Center, and Video Services.  These next generation of services can be readily deployed at low operational costs using the Cisco Transport Controller (CTC) and Cisco PRIME that allow fast and simple network turn up, A to Z provisioning and OAM features.

First to market with advanced standards based MPLS-Transport Profile (TP) management for ethernet aggregation and transport, MPLS-TP combines the feature richness of MPLS with the simplicity of transport operational models. In addition to MPLS-TP, the CPT family can support IP/MPLS and native ethernet based transport solutions, giving the customers data plane and control plane flexibility as the network evolves.

Its small form, simplicity, unique set of integrated features, and low power consumption reduce capital and operational expenditures. The CPT family reduces total cost of ownership based on its innovative satellite architecture that centralizes the management and allows scalable ethernet fan-out. The Cisco CPT 50 series satellite panel can be an extension of the CPT 600 Packet Transport Fabric and Modules thereby extending the service interface up by a factor of 10.

The Cisco CPT architecture is designed to provide a la carte options to deploy Packet Transport, MSTP or OTN switched networks. Allowing the customer to reduce day one costs and grow capabilities as required.

Key Features and Benefits

The Cisco CPT 600 chassis has two slots for redundant control cards and six slots for service cards. These six line card slots connect across the backplane to provide redundant aggregation and switching capability. The Cisco CPT 600 can be configured with integrated and redundant DC or AC power inputs. A single power module could be used for low-power and low-cost configurations. The DC power module has connectors for both ANSI or ETSI style battery and battery return connections, making it universal. The AC power module has a single input and is universal in that it accepts a power input ranging from 110 VAC to 240 VAC, 50 Hz to 60 Hz.

The Electrical Connection Unit is a narrow, front-facing termination panel for all your management, alarm, and multi-shelf connections. With all connections to the Cisco CPT 600 being front-facing, this platform is ideal for cabinet installations and ETSI front connection requirements, making this a truly global platform.

Although the node can be configured with redundant control or processor cards, simplex mode or single control card operation is permitted. The Cisco CPT 600 has a built-in memory module to back up the software package, IP address, and circuit database, making simplex mode more attractive in cost-sensitive applications. This built-in backup memory improves mean time to repair (MTTR) and increases operational simplicity. The ECU also has inputs for BITS and ToD (Time of Day) for support of SyncE and IEEE1588 Precision Timing Protocol.

The Cisco CPT 600 can be mounted in 19-, 21-, or 23-inch racks/cabinets and has brackets with integrated air deflectors to support the following options. With 19-inch brackets, the airflow is right to left. With 21-inch brackets, airflow can be selected as right to left; or right front in, and left front out; or left up out, or left back out. With 23-inch brackets, airflow is from right front in to left back out.

The Cisco CPT 600 has a single high-capacity fan tray assembly where the three fans are individually monitored and controlled. In the unlikely event that a single fan fails, the user will receive a fan fail alarm and the other fans will increase in speed to provide sufficient airflow to allow the user time to safely replace the fan tray.

The Cisco CPT 600 and control cards have features like multilayer graphical network, node, and card visibility; A-to-Z network-based service provisioning; and graphical software wizards to simplify and speed user operations for such tasks as initial network turn-up; service provisioning; and management of satellite panels.

In addition to the integrated software features, the Cisco CPT 600 is supported by an easy-to-use but powerful network design tool. This tool is a user-friendly, Java-based application (fully developed and tested by Cisco) for modeling and optimizing MPLS-TP networks based on the user’s network parameters.

Topology Flexibility

Cisco CPT 600 platform and cards provide both dense hierarchical QoS and support for Layer 2 services and features, using MPLS-TP, MPLS or Layer 2 Ethernet based technologies. With up to 64K queues per card, 16,000 service interfaces, 256K MAC addresses in a 6 RU NEBS/ETSI compliant chassis.  The platform and control cards also contain synchronization circuitry, a Stratum-3 clock and dedicated backplane timing traces enabling transport-class network timing, support of network-synchronized services and applications such as mobile backhaul and migration of TDM services.
