A G-Series card configured as a transponder operates quite differently than a G-Series card configured
for SONET/SDH. In SONET/SDH configurations, the G-Series card receives and transmits Gigabit
Ethernet traffic out the Ethernet ports and GBICs on the front of the card. This Ethernet traffic is
multiplexed on and off the SONET/SDH network through the cross-connect card and the optical card
