G-Series Transponder Mode Characteristics
The operation of a G-Series card in transponder mode differs from a G-Series card in SONET/SDH mode
in several ways:

A G-Series card set to transponder mode will not show up in the CTC list of provisionable cards
when the user is provisioning a SONET/SDH circuit.
G-Series cards set to transponder mode do not require cross-connect cards (for example, XC10G),
but do require TCC2/TCC2P cards.
G-Series ports configured as transponders do not respond to flow control pause frames and pass the
pause frames transparently through the card. In SONET/SDH mode, ports can respond to pause
frames and do not pass the pause frames through the card.
There is no TL1 provisioning support for configuring transponder mode. However, transponder
mode and port information can be retrieved in the output for the TL1 command RTRV-G1000.
All SONET/SDH-related alarms are suppressed when a card is in transponder mode.
There are no slot number or cross-connect restrictions for G1000-4 or G1K-4 cards in transponder
mode.
Facility and terminal loopbacks are not fully supported in unidirectional transponder mode, but are
supported in both bidirectional transponder modes.
Ethernet autonegotiation is not supported and cannot be provisioned in unidirectional transponder
mode. Autonegotiation is supported in both bidirectional transponder modes.
No end-to-end link integrity function is available in transponder mode.
