There are two kinds of Cisco DSP modules; the 542 and the 549. The 542 is the modules used in the devices that only support the FXO/FXS WICs. These support 1 FXx call per DSP and cannot, to the best of my knowledge, be used as a DSPFarm for conferencing or transcoding.
The 549 is the kind most often refered to when taking about DSPs. These are the DSPs used to support high-density voice in 2600/3600 and the 175X routers. These can be used to set up a DSPFarm for transcoding and conferencing, depending on router platform. The number of calls they support depends on the complexity of the codecs in use. One 549 DSP can support 4 Medium-complexity codec (i.e g.711) calls (apperently the PR people didn't like "low-complexity") and 2 high-complexity codec calls (i.e. g.729).
