We've got a 3300 CXi at a customers site, and they have only 4 VM ports programmed. In the 3300 I&M Course manual, it states:
"The case CX and CXi controllers allow up to 4 ports and, with increased DSP resources, up to 16 may be supported" (emphasis mine)
This site has the DSP card in port 3 - is this the increased DSp resources the manual references, or is there something else they will need?
