Cisco ONS 15500 Series

The Cisco ONS 15530 10-port ESCON Aggregation Card

Data Sheet

Cisco ONS 15530 DWDM
   10-Port ESCON Aggregation Card

The Cisco ONS 15530 10-Port ESCON Aggregation Card for the Cisco ONS 15530 DWDM Multiservice Aggregation Platform provides efficient wavelength usage by aggregating up to 10 Enterprise System Connection (ESCON) signals on a single 2.5 Gbps wavelength or up to 40 ESCON signals on a 10 Gbps wavelength. This enhances service capacity for the Cisco ONS 15530, making it ideal for both low-density and high-density storage applications.

High-density service aggregation

Provides industry-leading aggregation capabilities of up to 40 ESCON services per 10 Gbps ITU (International Telecommunication Union) wavelength or up to 10 ESCON services per 2.5 Gbps ITU wavelength. When used with a 32-wavelength system, such as the Cisco ONS 15540 system, up to 1280 ESCON services can be supported per fiber pair.

Investment protection

Provides investment protection for customers by allowing support of both low-density and high-density deployments with the same aggregation card in conjunction with 2.5 Gbps or 10 Gbps ITU trunk cards.


Support for scalable ESCON deployment sizes allows the network to grow and evolve with customer requirements. As a customer's network grows, additional ESCON services can be easily added to a Cisco ONS 15530 network.

Service mixing

When combined with the Cisco ONS 15530 10 Gbps Trunk Card and Cisco ONS 15530 switch fabric, network design flexibility and bandwidth efficiency can be achieved by allowing a single 10 Gbps wavelength to carry a combination of ESCON, Fibre Channel, FICON, and Gigabit Ethernet protocols between customer data centers. This greatly reduces the complexity of a network design by minimizing the number of wavelengths required.

Protection options

Offers several protection options for customers requiring an enhanced level of service availability, including client and trunk protection.

Performance monitoring

Offers digital performance monitoring, providing customers with added visibility into protocol statistics in addition to optical signal performance.


Compatible with storage solutions from Cisco partners, including IBM GDPS, EMC SRDF, HP/Compaq DRM, and HDS TrueCopy, allowing customers the choice of deploying the Cisco ONS 15530 platform in many types of storage environments with full confidence.

Storage applications

Provides aggregation of multiple ESCON services for storage networking applications such as business continuance, disaster recovery, disk mirroring, and storage-area network (SAN) extension.
