2.5.1 XC-VXL-2.5G Card Functionality
2.5.1 XC-VXL-2.5G Card Functionality
The XC-VXL-2.5G card manages up to 192 bidirectional STM-1 cross-connects, 192 bidirectional E-3
or DS-3 cross-connects, or 1008 bidirectional E-1 cross-connects. The TCC2/TCC2P card assigns
bandwidth to each slot on a per-STM-1 basis. The XC-VXL-2.5G card works with the TCC2/TCC2P
card to maintain connections and set up cross-connects within the node. You can establish cross-connect
and provisioning information through CTC.
Note Cisco does not support operating the ONS 15454 SDH with only one XC-VXL-2.5G card. Always
operate in a redundant configuration. Install the XC-VXL-2.5G cards in Slots 8 and 10.
2.5.2 XC-VXL-2.5G Card-Level Indicators
Table 2-16 describes the two card-level LEDs on the XC-VXL-2.5G faceplate.
2.6 XC-VXC-10G Card
Note For XC-VXC-10G card specifications, see the A.4.5 XC-XVC-10G Card Specifications” section on
page A-12.
The XC-VXC-10G card establishes connections at the VC-4, VC-3, VC-12, and VC-11 levels. The
XC-VXC-10G cards provides STM-64 capacity to Slots 5, 6, 12, and 13, and STM-16 capacity to Slots 1
to 4 and 14 to 17. Any VC-4 on any port can be connected to any other port, meaning that the VC-4
cross-connections are nonblocking. XC-VXC-10G supports LO circuits on SNCP with non intrusive
monitoring.
The XC-VXC-10G card can be configured to support either VC-12 or VC-11 grooming, or mixed
(VC-12 and VC-11) grooming.
Figure 2-7 shows the XC-VXC-10G faceplate and block diagram.

Card-Level LEDs Definition
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. The FAIL
LED is on during reset and flashes during the boot process. Replace the card
if the red FAIL LED persists.
ACT/STBY LED
Green (Active)
Amber (Standby)
The ACT/STBY (Active/Standby) LED indicates whether the
XC-VXL-2.5G is active and carrying traffic (green) or in standby mode to
the active XC-VXL-2.5G card (amber).
