DEFINED AS
"This class represents an assignment relationship between the termination point or GTP object listed in the From Termination attribute and the termination point or GTP objects listed in the To Termination attributes of the contained crossConnection managed objects.
A multipoint cross-connection can be established between one of CTP Sink, CTP Bidirectional, TTP Source, TTP Bidirectional, or GTP; and a set whose members are CTP Source, CTP Bidirectional, TTP Sink, TTP Bidirectional, or GTP.
The fromTermination attribute will always be non-NULL. The termination point or GTP object pointed to by the fromTermination attribute is related to all the termination point or GTP objects pointed to by the toTermination attribute of the contained crossConnection managed objects in such a way that traffic can flow between the termination points represented by these managed objects.
Information flows from the From Termination to the To Termination of the contained cross-connection objects.
If the objects listed in the fromTermination attribute and in the toTermination attribute of the contained crossConnection objects are GTPs, the nth element of the From Termination GTP is related to the nth element of the To Termination GTP (for every n).
The total rate of the From Terminations must be equal to the total rate of To Terminations in each contained crossConnection object.
The attribute Signal Type describes the signal that is cross-connected. The termination points or GTPs that are cross-connected must have signal types that are compatible.
The following are the definitions of the administrative state and the operational state attributes:
Administrative State:
- Unlocked: The mpCrossConnection object is administratively unlocked. It allows traffic to pass through each contained connection depending on its administrative state.
- Locked: No traffic is allowed to pass through the Cross-Connection between the cross-connected termination points. The effect of this value overrides the effect of the administrative state of each contained cross-connection.
Operational State:
The operational state of a Multipoint Cross-Connection object reflects the overall health of the cross- connection including all the Cross-Connection objects contained in the Multipoint Cross-Connection.
- Enabled: The Cross-Connection is performing its normal function. Note that some (but not all) of the cross-connection objects contained in the Multipoint Cross-Connection may be disabled.
- Disabled: The Cross-Connection is incapable of performing its normal cross-connection function. All the cross-connection objects contained in the Multipoint Cross-Connection are disabled.
Availability Status:
The supported values for this attribute are:
- In test
- Degraded: The Multipoint Cross-Connection is degraded in some respect. For instance, if one or more (but not all) Cross-Connection objects contained in the Multipoint Cross-Connection are disabled, the Multipoint Cross-Connection will be considered as degraded. The Multipoint Cross-Connection remains available for service (i.e. its operational state is enabled) while it is degraded.
- Empty SET."
