VOLUME II, CHAPTER 1, SYSTEM OVERVIEW
ART operation is designed to meet G.8262 synchronization mask requirements for
SyncE clock transport.
A RAC 60E can link to a RAC 6XE in non-CCDP mode.
Figure 1-3. RAC 60E
RAC 6XE
RAC 6XE adds CCDP operation to 60E capabilities. RAC 6XE additionally supports
ART.
Two RAC 6XE cards are operated as a CCDP pair, either in the same INU, or in sep-
arate co-located INUs to provide double the capacity over one channel, using both
the horizontal and vertical polarizations. An XPIC function between the RACs
ensures cross-polarization interference is eliminated.

DAC GE3
DAC GE3 capabilities include Synchronous Ethernet, link aggregation, policing,
ring/mesh protection and Ethernet service OAM.
