Hi there, I have been running Hiper DSP E1/T1 cards (code ver 3.5.13) for sometime now on ISDN E1 PRI lines. However, my telco provider wants to provision some new R2 E1 lines. I wanted to know if I need to make any hardware or firmware changes on the Hiper DSP cards to support the R2 lines. Cheers, Patrick Ndegwa
