2.4.1 XC10G Functionality

2.4.1 XC10G Functionality

The XC10G card manages up to 192 bidirectional STM-1 cross-connects. The TCC2/TCC2P card
assigns bandwidth to each slot on a per STM-1 basis. The XC10G card works with the TCC2/TCC2P
card to maintain connections and set up cross-connects within the system. You can establish
cross-connect and provisioning information through the CTC.
Note Cisco does not recommend operating the ONS 15454 SDH with only one XC10G card. To safeguard
your system, always operate in a redundant configuration. Install XC10G cards in Slots 8 and 10.

2.4.2 XC10G Card-Level Indicators

Table 2 -11 describes the two card-level LEDs on the XC10G card faceplate.
2.5 XC-VXL-10G Card
The XC-VXL-10G card cross connects E-1, E-3, DS-3, STM -1, STM-4, STM-16, and STM-64 signal
rates. The XC-VXL-10G provides a maximum of 384 x 384 VC-4 nonblocking cross-connections,
384 x 384 VC-3 nonblocking cross-connections , or 2016 x 2016 VC-12 nonblocking cross-connections.
It is designed for 10-Gbps solutions.
Note The XC-VXL-10G card has been designed to support both –48 VDC and –60 VDC input requirements.
