SAN Extension Beyond the Metro 

When a Fibre Channel link is extended over a long distance, the inherent flow-control mechanism can significantly 

reduce the overall throughput performance. The data muxponder card implements a buffer-to-buffer distance 

extension scheme that effectively increases the supported distance up to 1200 kilometers (km) for 1-Gbps Fibre 

Channel, 600 km for 2-Gbps, and 500 km for 4-Gbps. Buffer-to-buffer credit and R_RDY spoofing allows users to 

extend their business continuance and disaster recovery applications beyond the boundaries of a metro network. 

Management 

The Cisco ONS 15454 MSPT provides comprehensive management capabilities for operations, administration, 

monitoring, and provisioning (OAM&P) accessed through the integrated Cisco Transport Controller craft interface 

with support from the Cisco Transport Manager Element Management System (EMS). The data muxponder card 

incorporates provisionable digital wrapper (G.709) functions, providing DWDM wavelength performance-

management capabilities, especially for services being transported transparently across the network. Without the 

digital wrapper function, a carrier transporting a service transparently would be unable to identify network 
impairments that may degrade the transported signal and exceed SLA requirements. The digital wrapper’s general 

communication channel (GCC) enables a separate communications channel, versus the section DCC/regenerator 

section DCC (SDCC/RSDCC) in SONET/SDH signals, to be used by the platform when transparent signals are 

transported. This GCC enables the Cisco ONS 15454 to extend its advanced network autodiscovery capabilities to 

DWDM-based services. The integrated Cisco Transport Controller craft manager and the Cisco Transport Manager 

EMS provide the user with OAM&P access for the system.  

Performance Monitoring 

The data muxponder provides extensive performance-monitoring capability, by wavelength or service level. At the 

wavelength level, the card continuously monitors transmit and receive power, loss of signal or frame, alarm-indication 

signal, and remote defect indication. Additionally, based on the protocols of the client interfaces which include Gigabit 

Ethernet, 1-Gbps and 2-Gbps Fibre Channel, 4-Gbps Fibre Channel, FICON, and ISC, the card provides detailed 

performance statistics and alarms including 8b/10b code violation, received and transmit frame or packet count, and 

received and transmit R_RDYcount (Fibre Channel only). Enhanced performance monitoring allows the user to define 

additional criteria to better assess the health of the network and support the decision for protection switching. The 
card’s performance-monitoring capabilities provide support for G.709 (OTN). Calculation and accumulation of the 

performance-monitoring data is in 15-minute and 24-hour intervals as per G.7710. The data muxponder card also 

incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status at the card. An orange 

circle is printed on the faceplate, indicating the shelf slot in which the card can be installed.
