Address Element

0x25 - Subrate Channel

Use the Subrate Channel Address Type to address two subrate channels.

For a 1-way connection, enter the source subrate channel in Address Element 1 and the destination subrate channel in Address Element 2.

For a 1-way disconnect, enter the subrate channel to be disconnected in both Address Element 1 and Address Element 2.
