High Density OC-12/STM-4 Card for the Cisco ONS 15454 MSPP
The high-density OC-12/STM-4 card delivers greater service densities and advances system footprint on the Cisco® ONS 15454 Synchronous Optical Network (SONET) and Synchronous Digital Hierarchy (SDH) Multiservice Provisioning Platforms (MSPPs).
Background
The Cisco ONS 15454 is the industry's leading MSPP, with hundreds of customers and more than 40,000 systems deployed worldwide. The Cisco ONS 15454 SONET and Cisco ONS 15454 SDH platforms (see Figure 1) are a key building block in today's optical networks through its ability to offer next-generation transport capabilities and economics. The Cisco ONS 15454 offers supercharged multiservice transport capability by combining the best of a time-division multiplexing (TDM) system along with extensive Storage/Ethernet/IP data service offerings in a single platform. The Cisco ONS 15454 MSPP can aggregate traditional facilities such as asynchronous DS1/E1 or DS3/E3 circuits through OC-192/STM-64 along with data services, including 10BASE-T, 100BASE-T or Gigabit Ethernet onto optical transport facilities such as OC-48/STM-16, OC-48/STM-16 DWDM, and OC-192/STM-64 line interfaces. The Cisco ONS 15454's superior flexibility enables drastically improved efficiencies in the transport layer and breakthrough cost savings for initial and lifecycle deployment.

Cisco continues to expand service densities on the Cisco ONS 15454 MSPP with the introduction of the high-density OC-12/STM-4 card. The four-port OC-12/STM-4 card offers four times the density of the current OC-12/STM-4 card and enables service providers to expand the number of revenue-generating service interfaces from an existing or new Cisco ONS 15454. Enterprise users and service providers can also take advantage of lower overall network infrastructure costs by reducing the number of chassis and interface cards for future network build-outs.
High-Density OC-12/STM-4 Solution
The Cisco ONS 15454 allows service providers to take greater advantage of operational and networking enhancements achieved through higher port and service densities driving increasing revenue streams. Improved economics of the four-port OC-12/STM-4 card allow additional system interfaces for traffic aggregation and transport.
High-Density OC-12/STM-4 Applications
As the migration to 10 Gbps in the metro-optical network continues, bandwidth scalability and multiservice capability has become increasingly important for the next-generation optical network. The Cisco ONS 15454 and Cisco ONS 15454 SDH supports asynchronous traffic (DS1/E1, DS3/E3) and also scales up to OC-192/STM-64 for optical transport. In order to maximize footprint, cost, and flexibility, the four-port OC-12/STM-4 card provides four times the bandwidth per slot, versus the current single port OC-12/STM-4 cards.
With this increased port density, the service providers now have the option of dropping 10 Gb (see Figure 2) worth of protected bandwidth using eight four-port OC-12/STM-4 cards (1 + 1 protected) with a single Cisco ONS 15454 chassis. Each port is also configurable to support all Cisco ONS 15454 configurations and may be provisioned as part of a Bidirectional Line Switched Ring/Multiplex Section-Shared Protection Ring (BLSR/MS-SPR), Unidirectional Path Switched Ring/Sub-Network Connection Protection (UPSR/SNCP), or linear/multiplex switching protection (MSP) configuration. For SDH gateway applications, each port can be independently software provisioned as STM-4 for SDH tunneling applications on the Cisco ONS 15454 SONET platform.
