How to determine if DSPs installed in 2811?

I am fairly certain that I have PVDM2-48 48 channel packet voice/fax DSP module installed in my 2811 router.  "show hardware" does not indicate its presence.  But in another router I am clearly using DSP resources for conference calling.  What Cisco IOS "show" command indicates the presence of this DSP module?  Thanks.

Sample output of show hardware:
Cisco 2811 (revision 53.51) with 245760K/16384K bytes of memory.
Processor board ID FTX101010101011
2 FastEthernet interfaces
1 Gigabit Ethernet interface
1 Serial interface
2 terminal lines
2 Channelized T1/PRI ports
1 cisco service engine(s)
DRAM configuration is 64 bits wide with parity enabled.
239K bytes of non-volatile configuration memory.
126976K bytes of ATA CompactFlash (Read/Write)
