Two-Port Bidirectional Transponder Mode

In transponder mode, the G-Series Ethernet traffic never comes into contact with the cross-connect card
or the SONET/SDH network, but stays internal to the G-Series card and is routed back to a GBIC on that
card
Figure 23-8
A G-Series card can be configured either for transponder mode or as the SONET/SDH default. When
any port is provisioned in transponder mode, the card is in transponder mode and no SONET/SDH
circuits can be configured until every port on the card goes back to SONET/SDH mode. To provision
G-Series ports for transponder mode, refer to the Cisco ONS 15454 Procedure Guide or the
Cisco ONS 15454 SDH Procedure Guide.
All SONET/SDH circuits must be deleted before a G-Series card can be configured in transponder mode.
An ONS 15454 or ONS 15454 SDH can host the G-Series card configured in transponder mode in any
or all of the 12 traffic slots and supports a maximum of 24 bidirectional or 48 unidirectional lambdas.
A G-Series card configured as a transponder can be in one of three modes:
•
•
•
Two-Port Bidirectional Transponder Mode
Two-port bidirectional transponder mode maps the transmitted and received Ethernet frames of one
G-Series card port into the transmitted and received Ethernet frames of another port
Transponder bidirectional port mapping can be done from any port to any other port on the same card.
