2.6.1 XC-VXL-2.5G Card Functionality

2.6.1 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 recommend operating the ONS 15454 SDH with only one XC-VXL-2.5G card. To
safeguard your system, always operate in a redundant configuration. Install the XC-VX L-2.5G cards in
Slots 8 and 10.

2.6.2 XC-VXL-2.5G Card-Level Indicators

Table 2 -13 describes the two card-level LEDs on the XC-VXL-2.5G faceplate.
2.7 AIC-I Card
The optional Alarm Interface Controller–International (AIC-I) card provides customer-defined alarm
inputs and outputs, user data channels, and supports local and express orderwire. It provides
16 customer-defined input contacts and 4 customer-defined input/output contacts. It requires the
MIC-A/P for connection to the alarm contacts.
Note The AIC-I card supports both –48 VDC and –60 VDC input requirements.

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. Re place the card
if the red FAIL LED persists.
ACT/STBY L ED
Green (Active)

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).
