Card Slots and Types
XC10G Card
TheXC10G cross-connect card is the central switching element in the ONS 15454
SDH. You provision cross-connect (circuit) information using CTC; the TCC-I
then establishes the proper internalcross-connect informationand relaysthe setup
information to the cross-connect card.
Note For protection purposes, Cisco recommends duplex operation.
Duplex cross-connect cards must be the two XC10Gs.
The XC10G card cross-connects standard VC4, VC4-4c, VC4-16c and VC4-64c
signal rates and the non standard VC4-2c, VC4-3c, and VC4-8c signal rates
providing a maximum of 384 x 384 VC4 cross-connections. Any VC4 on any port
can be connected to anyother port,meaning thatthe VCcross connectioncapacity
is nonblocking. The XC10G card manages up to 192 bidirectional VC4
cross-connects. The XC10G card faceplate is shown in Figure 3.
