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.
