Description

Cross Disconnect Span 0x001D

This message disconnects all data paths of two spans that were previously connected by means of the Cross Connect Span message (XL_CrossConnectSpan).

NOTE: When cross-connecting channels across nodes in a CSP system, a separate message must be sent to each channel in the connection.

For example, you would send one message to Node 1: Cross Disconnect Span (CrossDisconnectSpan) 0,1. You would send another message to Node 2: Cross Disconnect Span (CrossDisconnectSpan) 1,0.
