Telecom Analysis Systems used to sell a satellite channel simulator that
worked at the RF level. According to their web site they have now sold this
line to dBm (http://www.taskit.com/customer_sle_product_support.htm).
If you want to add the delay at the data level, Adtech makes a line of delay
simulators that have an RS232 or V.35 interface (http://www.adtech-inc.com/)

Adding the delay at the IP layer instead of RF is easy using for
example dummynet on a FreeBSD bridge.
