I need to create an updated Asterisk install.  I'm planning on using FreePBX.
I have markings on an old Digium board 
TDM2400P rev A2
TDM2400P Rev B
DIGCN01ATDM2400P

Is there any reason I shouldn't use this board?
Are there better board options that have been improved that I should consider?

Thanks,

Gary Kuznitz
