Is anybody experiencing daisy-chain upgrading issue as I am about to deal with here. We have an 61C that maxed out the PRI channels and need to be upgraded to 81C. In order to do that I was told by my distributor that I have to upgrade the associated SCCS running 4.2 and CP running 2.0. On top of that I need to upgrade the NCC and SCCS, CP at another location. The whole upgrade costs between $250K and 300K. What a painful upgrade for just adding more PRI cards. Is there any alternatives to reduce that pain? Any help would be greatly appreciated.
