Chapter 1 System Overview
System Components
Additional discrete rates are also supported in regular 3R mode. For SM transponder line cards, these
rates fall between 16 Mbps and 2.5 Gbps; for MM transponder line cards, the rates are between
16 Mbps and 622 Mbps.
The system supports OFC (open fiber control) for Fibre Channel and ISC encapsulations. Alternatively,
FLC (forward laser control) can be enabled to shut down the laser on the client or trunk side if a Loss of
Light is detected on the other side.
The transponder line cards support autonegotiation for Gigabit Ethernet traffic.
Note The Cisco ONS 15530 transponder line cards do not support autonegotiation for 2-Gbps Fibre Channel.
The transponder line cards only recognize the configured clock rate or protocol encapsulation.
For detailed information about client interface configuration, refer to the
Cisco ONS 15530 Configuration Guide.
Protocol Monitoring
The transponder line cards can monitor protocol and signal performance. When monitoring is enabled,
the system maintains statistics that are used to determine the quality of the signal.
The following protocols can be monitored:
• ESCON (Enterprise Systems Connection)
• FC (Fibre Channel) (1 Gbps and 2 Gbps)
• FICON (Fiber Connection) (1 Gbps and 2 Gbps)
• GE (Gigabit Ethernet)
• ISC-3 links compatibility mode
• ISC-3 links peer mode (1-Gbps and 2-Gbps)
• SDH (Synchronous Digital Hierarchy) (STM-1, STM-4, STM-16)
• SONET (OC-3, OC-12, OC-48)
