Figure 14-8 Two-Port Unidirectional Transponder
14.2.4 G-Series Transponder Mode Characteristics
The operation of a G-Series card in transponder mode differs from a G-Series card in 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 an SDH circuit.
• G-Series cards set to transponder mode do not require cross-connect cards (for example, the
XC10G), but do require TCC2 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 SDH mode, ports can respond to pause frames and
do not pass the pause frames through the card.
• All SDH-related alarms are suppressed when a card is set in transponding 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 transponding mode but are
supported in both bidirectional transponding modes.
• Ethernet autonegotiation is not supported and cannot be provisioned in unidirectional transponding
mode. Autonegotiation is supported in both bidirectional transponding modes.
• No end-to-end link integrity function is available in transponding mode.
Note In normal SDH mode the G-Series cards support an end-to-end link integrity function. This function
causes an Ethernet or SDH failure to disable and turn the transmitting laser off the corresponding
mapped Ethernet port. In transponder mode, the loss of signal on an Ethernet port has no impact on the
transmit signal of the corresponding mapped port.
