I dont do RIP/OSPF/IPX. I just use IP for dialup. So why on commworks's site its said that for installing TCS 4.5/4.7 I need at least 128MbRAM and 16Mb flash? What about flash? I have just 8Mb of flash. Is it enough for upgrading to TCS4.5/4.7 ? And one more question: What happens if I upgrade DSP cards to TCS 4.5/4.7 and dont upgrade HARC and HNMC? Will dialup (dialin) work ok? Will my TCM see and be able to configure that DSP cards? Adam Barnhill wrote:

HARC Software v5.x.x suggest that you should have 128MB especially if you are doing any extra routing like ospf or IPX.

As far as connections, you should be fine.
