Cisco ONS 15454 Product Overview
Card Slots and Types
Note For protection purposes, Cisco recommends duplex operation.
Duplex cross-connect cards must be the same type (e.g. two XCs,
two XCVTs, or two XC10Gs).
XC Card
The XC card establishes connections and performs time division switching (TDS) at
the STS-1 level between ONS 15454 traffic cards.
The switch matrix on the XC card consists of 144 STS-1 bidirectional ports. Network
operators can concentrate or groom low-speed traffic from line (traffic) cards onto
high-speed transport spans and to drop low-speed traffic from transport spans onto
line cards.
XCVT Card
The XCVT card provides the same STS capability as a standard XC card but adds
VT1.5 cross-connect capability.
The switch matrix on the XCVT card consists of 144 STS-1 bidirectional ports
and adds a VT matrix that can manage up to 336 bidirectional VT1.5s. The
VT1.5-level signals can be cross connected, dropped, or rearranged.
XC10G Card
The XC10G card supports STS-192 signal rates. The switch matrix on the XC10G
consists of 576 STS-1 bidirectional ports and its VT matrix can manage up to 336
bidirectional VT1.5s. The XC10G is required to operate the OC-192 card or the
OC-48 any-slot cards.
