Hello,
UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) boards are cross-connect, system control, timing boards that provide communication control, service scheduling, and clock processing functions.
UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) boards support two working modes: Normal SCC mode and Simple SCC mode. When Simple SCC mode is set for the UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) boards on the NMS, the UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) boards run in low power consumption mode and their cross-connect function is disabled.
Table 1, Table 2, and Table 3 list functions and features supported by UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) boards.
System Control and Communication Unit
Table 1 lists the functions and features supported by the system control and communication unit of a UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) board.
Table 1 Functions and features that the system control and communication unit of a UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) board supports| Function and Feature | Description |
|---|
| Basic functions | Grooms services, manages configurations, and reports alarms in a subrack. Backs up NE Data. When the data of an NE changes, the system control and communication unit immediately saves changed data to a storage medium to ensure that the NE data still exists after the NE undergoes a cold reset or power failure. This feature improves NE reliability. Implements communication between NEs through IP over DCC or HWECC.
|
| Protection | |
| DCN | Supports outband DCN, inband DCN, and ESC functions. |
| Fan alarm management | Provides 1+1 power supplies to fans, supports fan speed adjustment and fan fault detection, and manages fan alarms. |
| Subrack fan operating mode configuration | Supported. |
| Power supply management | Checks whether the power input board can be detected. |
| Master/Slave subrack | Not supported. |
Cross-Connect Unit
Table 2 lists the functions and features supported by the cross-connect unit of a UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) board.
Table 2 Functions and features that the cross-connect unit of a UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) board supports| Function and Feature | Description |
|---|
| Basic functions | Supports two cross-connect modes: O+P+S (OTN, packet, and SDH) mode and O+S (OTN and SDH) mode. O+P+S mode: Implements non-blocked cross-connections of 160 Gbit/s ODUk (k = 0, 1, 2, 2e, flex) signals. Cross-connects and schedules 50 Gbit/s VC-4s, and 20 Gbit/s VC-12s/VC-3s. Supports a packet service switching capacity of 160 Gbit/s.
O+S mode: Implements non-blocked cross-connections of 200 Gbit/s ODUk (k = 0, 1, 2, 2e, flex) signals. Cross-connects and schedules 50 Gbit/s VC-4s, and 20 Gbit/s VC-12s/VC-3s.
NOTE:In O+P+S mode, a chassis-level packet function license is provided, whereas in O+S mode, no chassis-level packet function license is provided. |
| Service processing | For packet/TDM service performance specifications, see Feature Description. |
| Protection type | Supports 1+1 hot backup. |
| Energy Saving | Only hot backup is supported. |
Clock Unit
Table 3 lists the functions and features supported by the clock unit of a UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) board.
Table 3 Functions and features that the clock unit of a UXCL (Z1UXCL/Z2UXCL_Z1SCC_Z1STG) board supports| Function and Feature | Description |
|---|
| Basic functions | Implements clock synchronization on an NE, and provides system clock signals and frame header signals for service boards. The clock signals comply with ITU-T G.813 and ITU-T G.823. Traces the external clock source, service clock source, or local clock source, and provides clock signals for itself and the system. Supports IEEE 1588v2 time and frequency synchronization. Supports G.8275.1. Supports G.8273.2.
|
| Other functions | Supports extraction, insertion, and processing of SSM information and clock ID. Supports two external clocks by working with the TNF1AUX board.
