SwitchKit Name

CrossDisconnectChannel

Type

EXS API and SwitchKit API message

Description

This message instructs the Excel platform to disconnect the data paths of the channels specified (for SwitchKit, to disconnect the data paths of the channels that were connected by means of the CrossConnectChannel message).

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 Channel (CrossDisconnectChannel) A, B.

You would send another message to Node 2:

Cross Disconnect Channel (CrossDisconnectChannel) B, A.
