By the end of this week, there will be some more descriptive examples in the distribution that illustrate it's usage.  Right now, if you look in tcl/ex/snoop/snoop.tcl and tcl/lib/ns-ber.tcl you will see what there is and how to use it (snoop.tcl is the simulation script that uses error functions defined in ns-ber.tcl).  The C code for the error models is in errmodel.{cc,h}. More error models, including ones that are (arguably) more realistic, are on their way.

To understand examples of how to set up LAN topologies with link-layers, MAC protocols and a channel model, please look at tcl/ex/mac-test.tcl
