Chapter 14 Ethernet Operation
14.2 G-Series Gigabit Ethernet Transponder Mode
Figure 14-4 Card Level Overview of G-Series One Port Transponder Mode Application
A G-Series card configured as a transponder operates quite differently than a G-Series card configured
for SDH. In an SDH configuration, the G-Series card receives and transmits Gigabit Ethernet traffic from
the Ethernet ports and GBICs on the front of the card. This Ethernet traffic is multiplexed on and off the
SDH network through the cross-connect card and the OC-N card (Figure 14-5).
