Table 1-21 describes the10-Gbps ITU trunk card LED status.
10-Gbps ITU Tunable Trunk Cards
The 10-Gbps ITU tunable trunk card works similar to the 10-Gbps ITU trunk card. The 10-Gbps ITU
tunable trunk card sends and receives the ITU grid wavelength signal to and from an OADM module.
This card accepts up to four 2.5-Gbps (3.125-Gbps line rate) electrical signals from the 10-port ESCON
aggregation cards and 8-port FC/GE aggregation cards, and combines them into one 10-Gbps signal,
which is converted to the ITU grid wavelength, or channel. The 10-Gbps ITU tunable trunk card has four
separate redundant interfaces to the backplane, each connecting to the switch fabrics on the active and
standby CPU switch modules.
The 10-Gbps ITU tunable trunk card has two versions: nonsplitter and splitter. The nonsplitter version
has only one pair of optical connectors on the front panel, which connects to either the east or the west
OADM module, and can be used for unprotected, line card protected, or switch fabric protected
applications (see Figure 1-30). The splitter version of the 10-Gbps ITU tunable trunk card has two pairs
of optical connectors on the front panel, which connect to the east and west OADM modules, and is
designed for splitter protected applications (see Figure 1-31).
The Cisco ONS 15530 supports up to four 10-Gbps ITU tunable trunk cards for a total of four channels.
The 10-Gbps ITU tunable trunk cards are equipped with Universal Transponders (UT1) with tuneable
lasers. The cards are programmable to four different frequencies belonging to one of the A, B, C, D, E,
F, G, or H bands. For more information on tunable frequencies, see Cisco ONS 15530 Planning Guide.
