Chapter 1 System Overview
System Components
• 5 minute input/output rates
• Loss of Sync
• Loss of Light
For ISC-3 links traffic, the system monitors the following conditions on the 8-port FC/GE aggregation
card:
• 8B/10B CVRD error counts
• Loss of Light
Support for FC Port Types
The 8-port FC/GE aggregation card supports the following FC port types, with or without the buffer
credit distance extension feature enabled:
• B_port—bridge port
• E_port—expansion port
• F_port—fabric port
• N_port—node port
• TE_port—trunking E_port (Cisco MDS 9000 Family systems only)
Note All of the above port topologies, except for TE_port, are point-to-point in the FC specifications.
Examples of valid topologies where you can place a Cisco ONS 15530 shelf, which has an 8-port FC/GE
aggregation card, in the middle to extend distance include the following:
• E_Port <--> E_Port
• F_Port <--> N_Port
• N_Port <--> N_Port
• B_Port <--> B_Port
• TE_Port <--> TE_Port
The arbitrated loop topology is not supported by the 8-port FC/GE aggregation card. The arbitrated loop
port types not supported include:
• NL_port—node loop port
• FL_port—fabric loop port
• EL_port—extension loop port
Note Any combination of these arbitrated port types are not supported.
8-Port Multi-Service Muxponders
The 8-port multi-service muxponder accepts up to eight SFPs for client traffic. The eight client signals
are mapped into the right size STS-n payloads and multiplexed into a 2.5-Gbps ITU signal. The ITU
signal is then multiplexed onto the trunk by an OADM.
