What blocks should I use to replace the obsolete Distributor and Commutator blocks in the Signal Processing Blockset 6.0.1 (R14SP1)?

I know that the Distributor and Commutator blocks are now obsolete. I used these blocks in my previous Simulink models and would like to replace them. However, the documentation does not specify which blocks should be used in their place.

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:
We have verified that documentation on the blocks that should be used to replace the obsolete Distributor and Commutator blocks is missing from the Signal Processing Blockset 6.0.1 (R14SP1) manual.
The Distributor block should be replaced with the Buffer block, and the Commutator block should be replaced with the Unbuffer block (both found in the (Signal Management -> Buffers sublibrary). The Unbuffer block will only work with frame-based signals. Therefore, if the incoming signal to the Unbuffer block is not frame-based, you should first convert the signal to a frame-based signal using the Frame Conversion block (Signal Management -> Signal Attributes sublibrary). Then use the Unbuffer block.
